Pipe
Cutting
Basic Jointing/Pipe Cutting When cutting Hep2O®
pipe it is essential to use the correct tools. Only the recommended
cutters as shown in the Hepworth Building Products plumbing
price list (HD74, HD75, HD77 or HD78) should be used.
Do not use a hacksaw. (Figure No. 1)
Before making a joint ensure the pipe end is clean, cut square
and free from burrs and surface damage. (Figure No.2). Place
the pipe in the jaws of the cutter and apply pressure, the pipe
should be rotated whilst maintaining the pressure until the
pipe is severed. (Figure No. 3) |

To ensure adequate insertion, essential for a secure joint,
cut the pipe square at one of the cutting/insertion marks
'^^^'. The distance between these marks indicates full
socket depth (Figure No. 3). |
|
When it may not be possible to use the '^^^'
marks eg. badly lit areas, jointing copper pipe or where an
exact length is required, mark the insertion depth on the pipe
using a pencil or suitable marker pen. The correct insertion
depth can be obtained by holding the pipe against the fitting
or by measuring with a rule, as shown (Figure No. 4). The depth
of insertion is shown in Table 3 at the end of this section.

Support
Sleeve
ALWAYS insert a Hep2O®
support sleeve into the Hep2O®
pipe end. (Figure No. 5).
It is essential to use a support sleeve in order to make
a good joint. The support sleeve ensures that the pipe
retains a circular section and provides a leading edge
to the pipe for easier insertion (the only exceptions
to this rule are when using copper pipe, or the open spigot
end of a Hep2O®
fitting). |
