Rosemount 114C Thermowell

Product overview

Temperature sensors are rarely inserted directly into an industrial process. They are installed into a thermowell to isolate them from the
potentially damaging process conditions of flow-induced stresses, high pressure, and corrosive chemical effects. Thermowells are
closed-end metal tubes or barstock installed into the process vessel or piping and become an integral pressure-tight part of the process
vessel or pipe. They permit the sensor to be quickly and easily removed from the process for calibration or replacement without requiring
a process shutdown and possible drainage of the pipe or vessel.

The Rosemount 114C Thermowell is made from solid barstock to ensure strength and integrity. The Rosemount 114C was designed to
accommodate a host of industry standard configurations, but has the flexibility to adapt to special configurations for different types of
applications.

Flexible design modifiers accommodate many process requirements

 Different sizes of root (A), tip (B), and bore (d) diameters

 Different tip (t) thickness as required

 Numerous combinations for various industrial applications

 Meet ASME PTC 19.3 TW standard with flexible design

Thermowell calculations ensure thermowell design is compatible with process conditions

 Thermowells inserted into any process are subjected to forces

from the fluid flow.

 ASME released design standard PTC 19.3 TW that defines a

series of qualitative calculations to determine design suitability
to withstand process conditions.

 Calculations are based on process conditions, process fluid,

installation method, thermowell geometry and material.

 The thermowell calculation tool from Emerson is designed to

meet the ASME standard.

 The free online software version can be used for preliminary

calculations. Click here to access the tool.

 Formal calculations by our expert team of engineers are

available prior to order placement to ensure design is
acceptable.

 Recommendations are also made if thermowell design is found

to be unacceptable for the application.

 Order Thermowell Calculation option (R21) to receive a formal

report with product shipment.

Selection guide

Ensure sensor fits thermowell

Rosemount 114C Head length (H) + Immersion length (U) = Rosemount 214C Sensor insertion length (L).

Basic selection guide

Selecting the proper thermowell for an application is an important activity as it impacts plant safety and measurement efficiency.
Thermowells are considered a wetted part; they physically become part of the pressure retaining system.

The four major factors to consider when selecting a thermowell for an application are described below:

Thermowell length

There is no standard formula to determine thermowell immersion length. However, there are a few common practices that the
process industry follows along with good engineering judgment. Ideally the thermowell tip should be located near the centerline in
turbulent flow conditions because this represents the most accurate process temperature.

To ensure optimal performance, a general guideline for immersion length into a pipe is as follows:

 10⫻ the thermowell root diameter for air or gas

 5⫻ the thermowell root diameter for liquids

Another guideline is at least one-third the way into the pipe for any measurement. The American Petroleum Institute (API) has a
specific recommendation of using an immersion length of the sensing element plus 50 mm (2-in.).

Mounting configuration

Consider how the thermowell is mounted on the pipe or tank. The process designer typically specifies what mating connection will
be used and the thermowell selected should match that connection. Temperature, pressure, and material are usually taken into
consideration to ensure the process connection will be adequate for the application. Welded, threaded, flanged, and Van Stone are
standard mounting configuration options.

Thermowell stem profile

Factors to be considered when selecting a stem style include the process pressure, required response speed of the measurement,
drag force of the fluid flow on the well, and the wake frequency. The stem or shank is the part of a thermowell inserted into the
process piping or vessel. Straight, stepped and tapered stem styles are available. Each profile has its advantages depending on the
need and situation.

Thermowell material

Rosemount Thermowells are supplied in most materials required for industrial applications. Standard materials are 316/316L
Stainless Steel, 304/304L Stainless Steel, and A105 Carbon Steel. For corrosive environments, special materials such as Alloy C-276
and Alloy 600 are also available. See the ordering table for a complete listing of standard materials. Contact your local Emerson
representative for additional material availability.

Threaded installation

Threaded thermowells are screwed into the process using a threaded fitting or directly into a tapped pipe if there is sufficient wall
thickness. Tapered threads will deform to each other to create a seal. Thread sealant and appropriate torque should be applied to
reduce risk of leaks.

Flanged thermowell overview

All Rosemount flanged thermowells are manufactured in accordance with ANSI B16.5. The flange to stem weld is in accordance to
ASME Section IX. There is also full traceability with material certifications available on request. Rosemount flanged thermowells are
available in two manufacturing configurations: full and partial penetration welds.

Full penetration weld (F) Partial penetration weld (P) Forged, no welds (G)

 Stronger weld

joint per ASME
PTC 19.3 TW

 Used for heavy

duty
applications

 Emerson recommended option

Figure 8. Standard Offering–Flanged

 Adequate for

most process
applications

 Weld withstands

same pressure
and temperature rating as flange

 Lower cost than full penetration weld

 Highest fatigue

resistance per
ASME PTC 19.3
TW

 Eliminates weld

qualifications and failures

 Used in extreme process applications

The common options shown in Figure 8 represent a partial offering; reference the Rosemount 114C Flanged Ordering Information
for a full list of available options.

Flanged installation

Flanged thermowells are bolted to a mating flange which protrudes from the process. It is important to select appropriate gasket for
the process conditions, to provide a seal between the flange faces. The Rosemount 114C Thermowells come standard with a raised
face and spiral serrations designed per the ASME B16.5 standard. These should be installed with an inside bolt circle (IBC) gasket/ring
gasket, which extends to and is centered by the bolts. Other flange face options are available.

Van Stone thermowell overview

Van Stone/lap Joint thermowells are mounted between the mating flange and lap joint flange. This unique design enables thermowell
designers to specify thermowell flange materials different than the thermowell stem material; flanges are easily replaceable. These
thermowells allow use of different thermowell materials for the flange contacting the process and overlaying flange which can save
material and manufacturing costs. They are a good choice for corrosive applications, because there are no welds so weld-joint
corrosion is eliminated. The Emerson standard for the Van Stone thermowell is a raised face style made of carbon steel. Other styles
and flange materials are also available.

The standard offering figure below shows the thermowell configurations that can typically be shipped in two weeks or less.

Figure 13. Standard Offering–Van Stone

The common options shown in Figure 13 represent a partial offering; reference the Rosemount 114C Van Stone Ordering Information
for a full list of available options.

Van Stone installation

Van Stone thermowells are installed using a lap joint flange
which slips over the stub end of the thermowell. The lap joint
flange has no flange face. Instead the flange is bolted over the
stub end which acts as the flange face and compresses the
gasket. The Rosemount 114C Thermowells come standard with
spiral serrations on the stub end designed per the ASME B16.5
standard. These should be installed with an inside bolt circle
(IBC) gasket/ring gasket, which extends to and is centered by the
bolts. Other flange face options are available.

Provides a Van Stone stem with a matching lap flange per stem
material. Coatings do not apply to lap flange.

Welded thermowell overview

Welded thermowells are permanently welded to process pipes or tanks. Welded thermowells have the highest pressure rating and
are generally used in applications with high velocity flow, high temperature, or extremely high pressure. They are necessary where a
leak-proof seal is required.

The standard offering figure below shows the thermowell configurations that can typically be shipped in two weeks or less.

Figure 18. Standard Offering–Welded

The common options shown in Figure 18 represent a partial offering; reference the Rosemount 114C Welded Ordering Information
for a full list of available options.

Socket weld installation

Socket weld thermowells are typically welded into a socket weld fitting. Welds should be designed according to the appropriate
standards. It is important to order a head length (H) that leaves enough space so the instrument threads will not be deformed by
welding at installation. The customer should also make sure the root diameter of the thermowell will fit through the inner diameter of
the weld fitting.

Note

When specified in a thermowell calculation, the unsupported length for a socket weld thermowell is from the point of weld (B shown
on Figure 21 on page 54) to the thermowell tip.

The immersion length normally refers to the length of the thermowell stem beginning underneath the process connection to the tip
of the thermowell. This length is typically specified by the process designer but the general rule is at least one-third or one-half the
pipe diameter. Thermowells longer than 42-in. will be required to have an internal pressure test (Q85) performed to ensure the
internal cavity integrity has not been compromised. Parallel thread thermowells have a U length that actually includes the process
threads thus requiring an extra 1-in. (25 mm) for min. U length.

Straight style thermowells (1)

Straight style thermowells have the same diameter along the entire immersion length. They
present the largest profile to the process medium and have the highest drag force compared
to other styles with the same root diameter. Because of the large tip diameter, there is more
mass to heat which slows the thermal response of the measurement assembly. The minimum
immersion length (U) allowed with this profile is 1-in. (25 mm) except for parallel threaded thermowells that have a minimum
immersion of 2-in. (50 mm).

Tapered style thermowells (2)

Tapered style thermowells have an outside diameter that decreases uniformly from root to
tip. For the same root diameter, this design represents a good compromise between straight
and stepped thermowells. It’s drag will be less than a straight style, but greater than a
stepped style. The response time will be faster than a straight style and slower than a stepped
style. The two general forms of a tapered stem are uniform (tapered from root to tip) and non-uniform (straight portion followed by
tapered portion). Because of its profile shape, it is a good compromise for strength between the two other styles. It is the common
choice for high velocity flow applications where the flow forces typically are too great to use a stepped well. The tapered design has
faster response than the straight style offering an optimal balance of strength and response time factors. The minimum immersion
length (U) allowed with this profile is 1-in. (25 mm) except for parallel threaded thermowells that have a minimum immersion of 2-in.
(50 mm). The maximum length allowed for the tapered profile is; Immersion length (U) + Head length (H) <= 4-in. (1067 mm)

Stepped style thermowells (3)

Stepped style thermowells have two straight sections with the smaller diameter straight
section at the tip. For the same root diameter as a straight profile thermowell, this design has
less profile exposure to the flowing process and exhibits less drag force and quicker response
time due to the smaller mass at the tip. In general, stepped thermowells will have thinner
walls. By the geometry of its design, the stepped well has a higher natural frequency than the other styles with the same root
diameter, and is less susceptible to vibration induced failure. Since this design has less material at the tip, its considered the best
thermowell for fast time response. The minimum immersion length (U) allowed with this profile is 3-in. (75 mm) except for parallel
threaded thermowells that have a minimum immersion of 4-in. (100 mm).

Thermowell material

Back to Threaded ordering table

Back to Flanged ordering table

Back to Van Stone ordering table

Back to Welded ordering table

The material of construction is typically the first consideration in choosing a thermowell for any given application. Three factors
affect the choice of material:

1. Chemical compatibility with the process media to which the thermowell will be exposed.

2. Temperature limits of the material

3. Compatibility with the process piping material to ensure solid, non-corroding welds and junctions.

It is important the thermowell conforms to the design specs of the pipe or vessel it will be inserted into to ensure structural and
material compatibility. The original process design most likely included temperature, pressure, and corrosive considerations as well
as cleaning procedures, agency approvals required, and conformance with codes or standards. Since an installed thermowell
essentially becomes part of the process, these original design considerations also apply to the thermowell and will drive the
thermowell material of construction and mounting type selection. International pressure vessel codes are explicit about the types of
materials and methods of construction allowed.

Thermowell calculation (R21)

Back to Threaded ordering table

Back to Flanged ordering table

Back to Van Stone ordering table

Back to Welded ordering table

The ASME PTC 19.3TW is internationally recognized as a mechanical design standard yielding reliable thermowell service in a wide
range of temperature measurement applications. It includes evaluation of stresses applied to a barstock thermowell as installed in a
process based on the design, material, mounting method, and process conditions. The documentation provided will detail the
process information, thermowell geometry, and comprehensive calculation analysis. It will also provide an acceptable or
unacceptable statement based on the analysis.

There are four quantitative criteria in ASME PTC 19.3 TW for a thermowell to be found acceptable for a particular set of process
conditions:

 Frequency Limit: the resonant frequency of the thermowell must be sufficiently high so that destructive oscillations are not

excited by the fluid flow.

 Dynamic Stress Limit: the maximum primary dynamic stress must not exceed the allowable fatigue stress limit. If the design

requires that the thermowell pass through the in-line resonance to get to the operating conditions, there is an additional fatigue
check at resonance.

 Static Stress Limit: the maximum steady-state stress on the thermowell must not exceed the allowable stress, as determined by

the Von Mises criteria.

 Hydrostatic Pressure Limit: the external pressure must not exceed the pressure ratings of the thermowell tip, shank, and flange

(or threads).

Emerson.com/Rosemount

Rosemount 114C

In addition, the suitability of the thermowell material for the process environment must be considered. This means the designer must
evaluate how corrosion and erosion affects the thermowell as well as how exposure to the process conditions affects material
properties.

Positive Material Identification (PMI) is a test that verifies the thermowell material is as specified by the Rosemount 114C model code.
X-ray/radiograph fluorescence (XRF) is used to provide elemental analysis in a nondestructive manner. The certificate will provide
PMI results in comparison with the applicable material standards for each individual thermowell and state the reference standard.
Two points are provided on flanges. All other thermowell components (including welds) will have a single point. XRF will not detect

Surface finish certification (Q16)

Back to Threaded ordering table

Back to Flanged ordering table

Back to Van Stone ordering table

Back to Welded ordering table

Thermowell surface finish is typically done to remove all the burrs and sharp edges which smooths the thermowell stem surface. The
Rosemount 114C comes with a standard surface finish of T32 in. CLA N6 (0.8 μm Ra) or better. This option provides a certificate
that documents the maximum surface finish reading for stem and flange (when applicable) and a pass/fail statement. Improved
surface finish options are also available for the Rosemount 114C (see options R14 and R20).

Surface finish <Ra 0.3 μm (12 μin) (R14)

Back to Threaded ordering table

Back to Flanged ordering table

Back to Van Stone ordering table

Back to Welded ordering table

Improves surface finish to be less than Ra 0.3 μm. An improved surface finish will increase corrosion resistance and make the
thermowell easier to clean. This is common in sanitary applications.

Electropolish (R20)

Back to Threaded ordering table

Back to Flanged ordering table

Back to Van Stone ordering table

Back to Welded ordering table

The electropolish process uses a combination of electrical current and chemicals to improve the surface finish. The surface will
appear shiny and polished. It can have an advantage over mechanical polishing because there is no cold work involved that can lead
to scratches, strains, metal debris, and embedded abrasives on the surface. An improved surface finish will increase corrosion
resistance and make the thermowell easier to clean. This is common in sanitary applications.

Larger root diameters will provide greater strength. Changing the root diameter is helpful when designing a thermowell to pass wake
frequency calculations.

Guidelines on specifying design modifiers based on the stem profile are as follows:

 Straight – only root diameter (Axxx) should be specified

 Tapered – both root (Axxx) and tip diameter (Bxxx) must be specified

 Stepped – if root diameter (Axxx) only is specified, the tip will be standard 0.5-in diameter; if tip diameter (Bxxx) is ordered, root

diameter (Axxx) must also be specified

Lap flange material for Van Stone design (C0X)

Back to Van Stone ordering table

This option is only available when the Van Stone (V) mounting configuration is selected. By default, a Van Stone thermowell comes
with a carbon steel A105 lap flange. These options give the choice of having the thermowell ordered without a flange, with a
316/316LSST flange, or with a flange of similar material as the thermowell stem. Below are some model string examples of the
standard offering and options for reference:

Example model: 114CE0030VAA2SC032A – carbon steel A105 lap flange with 316/316L SST thermowell stem provided (standard)

Example model: 114CE0030VAA2SC032AC01 – no lap flange, only thermowell stem provided

Example model: 114CE0030VAA2SC032AC02 – changes default carbon steel A105 lap cover flange to 316/316LSST flange

Example model: 114CE0030VAA2SC032AC03 – changes default cover flange to match thermowell stem material

Note

Coatings do not apply to lap flange.
