Introduction

General Description

The pipe preparation tool is designed to provide a fusible surface
on any polyethylene pipe material (new, weathered or previously
installed) in accordance with Gas Industry Standards GIS/PL2-5 Part 5
Electrofusion Ancillary Tools.

A small layer is removed from the pipe with each pass of this tool, this
provides a suitable, fusible surface from which pipe welding can occur
more easily.

This product (Caldertech Uniprep 7) has been manufactured,
inspected and tested in accordance with the ISO9001 quality control
systems and procedures in place at Caldervale Technology Ltd,
Dewsbury.

The unit has rotating pre-set spring tension load indicator that
is used to apply the correct load to the cutting tip around the
whole pipe.

Important!

This tool should be used in accordance with the pipe manufacturers’
recommendations and in line with local codes of practice.

This manual outlines the operation of the pipe surface preparation
tooling for the scraping of polyethylene pipe and forms a part of the
product to which it relates. It should be kept for the life of the product.
Any amendments issued by Caldervale Technology Ltd should
be incorporated in the text. The manual should be passed to any
subsequent holder or user of this product.

Before Using

02. Safety Instructions

02.

Safety Instructions

1. Read and understand the whole instruction booklet before using
the tool.

2. It is imperative that all possible precautions are made to avoid
unexpected pipe movement when the tool is being used.

3. Never use the tool on pipes that are not within the specified
dimensions.

4. The tool tip holder spring tension is factory set and MUST NOT be
tampered with, without adequate training or instruction.

5. Operatives should wear eye protection, gloves, safety headwear and
footwear when using the equipment.

6. A single scrape / pass cannot be guaranteed to provide 100%
preparation, where this is required users are advised to consider
making 2 scrapes around the pipe.

Familiarisation with the Tool

The tool is made up of 4 main parts:

1. A spring-loaded scraper arm which holds the blade within a
load indicator.

2. A threaded shaft with crank handle for traversing the scraper;

3. A spanner to expand the body;

4. An expanding body to fix the tool axially in the pipe;

Operating Instructions Uniprep 7 Rotary Scraping Tool

Pipe Preparation

1. Inspect the end of the pipe to be scraped to ensure it has no
damage or deep scores and that it is externally clean.

2. Check that the pipe is round. Ovality should be reduced where
possible. (Re-round with re-rounding tool if required).

3. Check that the end has been cut reasonably square.

4. Measure the insertion depth of the fitting and add on a minimum of
25mm (35mm recommended) to give a scraping witness. Mark the
distance (from furthest protruding face of pipe end) and cross hatch
that length of pipe with suitable pen such as white china pencil.

Using the Scraping Tool

Firstly, check the expanding body, ensure all parts are present and
nothing is loose or hanging o the tool.

1. Insert expanding body of the tool into pipe making sure the feet are
past the point of any pipe end regression with the Feed Screw collet
outermost.

03. Operation

2. Using supplied hex spanner locate on Feed Screw Collet expand the
body by turning anti-clockwise until very tight, aiming to leave the
Feed Screw Drive knob uppermost. Once tight, remove the spanner.

3. Quarter turn the feed screw drive knob to raise and disengage the
thread driver (if not already in position). Next fully insert the feed
screw and engage the feed screw driver by turning the feed screw
drive knob a quarter turn. Unscrew the crank arm T screw ready to
receive the scraper arm.

4. Raise the crank handle and insert the scraper arm. (Note it is highly
recommended to have the crank handle and scraper arm together
in the same orientation to prevent injury from rotation of the tool)
Lower the scraper arm until the scraper tip is approximately 6-10mm
from the pipe surface and lock in position with the crank arm T
screw.

5. Mark the position of the blade tip on the pipe to identify the point
when the telescopic scraper arm is retracted. This mark is used to
identify when the feed screw is nearing the end of the thread and to
prevent the scraper arm falling out and/or being damaged.

05

Operating Instructions Uniprep 7 Rotary Scraping Tool

6. Loosen the two arm extension wing nuts, extend the scraper arm
until it reaches the witness marking and lock in position.

7. Ensure the angle relief wing nut is tightened and does not allow the
tool tip cartridge to pivot then release the cutting arm release knob
and lower the spring-loaded scraper arm and blade onto the pipe.

8. Use the cutting arm T screw to adjust the spring tension until the
load indicator is set on top of the cutting tip (top of the cap head
screw is flush with the round boss).

9. Slowly turn the crank handle clockwise to rotate the cutter once
round the pipe whilst continually keeping an eye on the load
indicator, adjust the spring tension if required to apply the correct
load at the pipes lowest spot.

10. Double check the Feed screw driver is engaged on the shaft then
begin scraping until the mark made earlier is reached.

11. At the point where the mark is reached release the blade tension
(with the cutting arm T screw), lift and lock the arm (using the
cutting arm release knob).

03. Operation

06

12. Disengage the feed screw drive knob and slide the feed screw back
in to the start position. Re-engage the feed screw drive knob.

13. Loosen the two wing nuts, retract the arm to line up with the end of
the scrape and lock in position.

14. Release the arm using the cutting arm release knob and adjust the
spring tension until the load indicator is set. Continue to scrape
keeping an eye on the load indicator on the first rotation; adjust
tension as necessary to set it for any pipe lowest spot.

15. If the pipe being scraped has any pipe end regression the Cutting
Tip Angle Relief Wingnut needs to be loosened to allow the cutting
tip to remain in full contact with the pipe and give a good scrape.

Note: keeping an eye on the load indicator at this stage is
essential to a good scrape

16. Continue until the scrape is complete.cutter on to the pipe wall
surface and the correct pressure will be applied to the tip (6) via the
tool tip spring.

04. Removal After Completion

04.

Removal After Completion

1. Use the Cutting arm T screw to release blade spring tension.

2. Lift and lock scraper arm using cutter arm release knob.

3. Ensure the angle relief wing nut is tightened and does not allow the
tool tip cartridge to pivot.

4. Release the feed screw drive knob and slide out feed screw and
scraper arm and crank handle.

5. Separate scraper arm from crank handle using Crank Arm T Screw.

6. Use spanner clockwise to remove expanding body.

7. Ensure all parts are clean and dry.

8. Put all parts away in transport cases to protect them.

Storage

IMPORTANT! When not in use always:

1. Store the tool in the transport cases, ensure it is clean and dry
before storage.

2. Ensure cutter tip will not get damaged when transporting or storing
as this can severely limit the quality of the scrape.

Routine Maintenance

1. Check for correct movement and operation and lubricate moving
parts at regular intervals before using.

2. It is important to ensure all component parts are present and in
serviceable condition. In addition, the condition of the cutting /
peeling tip should be checked for damage or excessive wearing.

3. The cutter tip can be replaced. Spares are indicated in the parts
diagram.
