1 ABOUT THE MANUAL

This manual has been prepared as an aid and guide for personnel involved in installation or maintenance. All instructions must be read and understood thoroughly before attempting any installation, operation or maintenance.

SAFETY INSTRUCTIONS

Emerson does not have any control over the manner in which its hydraulic adapter is handled, installed or used and Emerson cannot and does not warrant or guarantee that the hydraulic adapter is suitable for or compatible with the user's specific application.

WARNING

Pressurized fluid streams can exit pipelines unexpectedly or unusual mechanical stresses can cause material failure. Safety glasses should be worn when installing or operating a hydraulic adapter. Failure to follow any instruction could result in a malfunction of the adapter with resulting sudden release of pressure, property damage or physical injury.

2 INTRODUCTION

Penberthy hydraulic adapters are intended to be used in place of standard gagecocks. They are supplied as a set (upper and lower connections) and attach to each end of a ⅝" (16 mm) or ¾" (19 mm) OD sight glass tube. This combination then forms a tubular glass gage.

2.1 System description

The Penberthy hydraulic adapter is machined from one of three standard materials: carbon steel, brass or 316 STS. It provides a ½" NPT male connection that allows you to incorporate most standard hydraulic connections currently available. Some of the options available to a gagecock style tubular glass gage can also be used with hydraulic adapters.

4 INSPECTION

On receipt of a hydraulic adapter, check all components carefully for damage incurred in shipping. If damage is evident or suspected, do not attempt installation. Notify the carrier immediately and request a damage inspection. A typical Penberthy hydraulic adapter set consists of (1) upper glass connection and (1) lower glass connection. Each connection contains (1) body, (1) glass packing, (1) glass packing gland and (1) glass packing nut.

The user should confirm that: A. The unit delivered matches the description

on the purchase order.

B. The operating conditions originally

described match the actual operating conditions at the installation site.

C. The actual operating conditions at the

installation site are within the design rating for the unit delivered.

D. The materials of construction for the

hydraulic adapter delivered are compatible with the conditions at the installation site.

SAFETY INSTRUCTIONS

If the size, model or performance data of the hydraulic adapter as received does not conform to any of the criteria above, do not proceed with installation. Contact an authorized Penberthy distributor for assistance. The incorrect adapter can result in unacceptable performance and potential damage to the tubular glass gage.

5 INSTALLATION

Installation should only be undertaken by qualified personnel who are familiar with this equipment. They should have read and understood all of the instructions in this manual.

WARNING

The hydraulic couplings must be mounted securely to the vessel or a stable framework. Failure to follow instructions could result in the separation of the sight glass from the hydraulic adapter stuffing box and a sudden release of pressurized fluid causing serious personal injury and property damage.

5.1 Attachment of the hydraulic fittings

A. Connect both the upper and lower adapters

to your hydraulic fittings. Use PTFE tape, or equivalent, on all male pipe threads. SeeFigure 1.

B. Tighten connections to a pressure tight joint.

5.2 Sight glass installation

A. Loosen both the upper and lower

glass packing nuts. Insure there is no compressive force on glass packing.

B. Move the upper adapter so it is offset from

the lower adapter and will allow the sight

glass to be inserted. C. Insert sight glass up into the upper adapter. D. Hold sight glass with upward force to check

that it clears the lower adapter. Check

vertical alignment of adapters. E. Pull sight glass down into the lower adapter

until you achieve a positive stop. F. Tighten both the upper and lower glass

packing nuts.

In some cases it may be necessary to remove glass packing nut, glass packing gland, glass packing and glass packing retainer and mount them to the sight glass prior to insertion of glass in upper and lower gagecock bodies. SeeFigure 2, the exploded parts diagram, for the proper sequence.

6 OPERATION

6.1 Pre-operational check

Before startup, the operator should ensure that: A. All installation procedures have been

completed.

B. All connections are pressure tight.

6.2 Hydrostatic test

A. Take all precautions necessary to handle

the possibility of leakage.

B. Hydrostatic pressure test the installation to

at least 100 psig (690 kPaG) and correct any leakage before proceeding.

6.3 Operation

Tubular glass gages should be brought into service slowly to avoid excessive thermal shock or mechanical stress on the tubular glass and potential glass breakage. By introducing the process fluid in this manner you allow the gage temperature and pressure to equalize slowly with the vessel.

WARNING

Failure to follow the recommended operating procedures for tubular glass gages can result in the rapid pressurization of the gage assembly. This can cause glass breakage and the sudden loss of pressure. Serious personal injury and property damage can occur.

7 MAINTENANCE

Maintenance should only be undertaken by qualified, experienced personnel who are familiar with this equipment and have read and understood all the instructions in this manual. The user must create maintenance schedules, safety manuals and inspection details for each specific gage and hydraulic adapter installation. These will be based upon the users own operating experience with their specific application. Realistic maintenance schedules can only be determined with full knowledge of the services and application situations involved.

WARNING

Do not proceed with any maintenance on a hydraulic adapter with the tubular glass gage still at operating pressure or temperature. Relieve the unit of pressure or vacuum, allow it to reach ambient temperature, and purge or drain it of all fluids. Failure to follow instructions could result in the sudden release of pressurized fluid causing personal injury or property damage.

7.1 Preventative maintenance

On all installations, check the following items regularly: A. Adapters, for signs of leakage around

hydraulic fitting connections. B. Adapters, for signs of leakage around

stuffing box connection. C. Adapters, for signs of internal or external

corrosion. D. Sight glass, for signs of etching or

scratching.

7.2 Maintenance procedures

A. Signs of leakage around the hydraulic

fitting connections indicates the lack of a

pressure tight joint. This can be remedied

by tightening the connection or removing

and replacing the PTFE tape on the adapter

threads. B. Signs of leakage around the stuffing box

indicate worn glass packing or improper

compression of glass packing. To replace

glass packing, follow Disassembly steps

1through 6 and Reassembly steps

1through 8. In the event of improper

packing compression, leakage can be

stopped by tightening glass packing nut. C. It is the user's responsibility to choose a

material of construction compatible with

both the contained fluid and the surrounding

atmosphere for the user's specific

application. If internal or external corrosion

is present, an investigation must be carried

out immediately by the user as to the cause

of the problem. This includes consulting

with an authorized Penberthy distributor. D. For broken sight glass replacement,

follow Disassembly steps 1, through 6 and

Reassembly steps 1 through 8.

IMPORTANT

New glass packing must be used when replacing glass.

WARNING

Do not proceed with the disassembly if the tubular glass gage is still at operating pressure or temperature. Relieve the unit of pressure or vacuum, allow it to reach ambient temperature, and purge or drain it of all fluids. Failure to comply could result in the sudden release of pressurized fluid causing personal injury or property damage.
