SCOPE:
Outlined specification DIN 8077 / 78. This pipe
is intended for use in applications where the fluid conveyed
does not exceed 95° C.
PP-R
MATERIALS:
The material used in the
manufacture of the pipe shall be domestically produced
Polypropylene co-polymer compound with other additives.
PP-R grade AER003N of Reliance Industries
Ltd.
DIMENSIONS:
PP-R Pipes shall be manufactured in strict
accordance to the requirements of DIN:8077/78 for physical
dimensions and tolerances. Each production run of pipe
manufactured in compliance to this standard, shall also meet
or exceed the test requirements for materials, workmanship,
creep strength, impact strength, heat reversion, density, melt
flow index etc..

manual welding machine
Polyfusion welding:
Step 1: Cut the pipe upright to
the axis of the pipe.
Step 2: Clean the die durface properly and
ensure Machine temperature has reached to 260° C.
Step 3: Insert pipe and fitting into
respective die and allow to heat as per table given
above.
Step 4: Remove the pipe and fittings from
the dies and immediately push the pipe into the socket
and allow it to cool as per table given above.
