1.Standard
The PE pipe for water supply of our company is produced
and detected strictly according to GB/T13663-2000,
ISO4427-1990 and GB/T17219.
2.Color
The color of our PE pipe for water is black and the
stripe is blue.
3.Series and specifications
The PE pipe for water supply of our company can be
classified into two series of PE80 and PE100 according
to PE materials. PE80 pipe series includes SDR11,
SDR13.6, SDR17, SDR21, SDR33 and so on. PE100 pipe
series includes SDR11, SDR13.6, SDR17, SDR21, SDR26
and so on..
4.Length
Usually the pipe length is 6m,9m,12m.Also we can
product any length pipe to satisfy our customers.Pipe
less than 63mm can be coiled,the length is 50m,100m,150m
etc.Specially,pipe diameter between 75mm and 110mm
can be coiled also according customers requirements.

Only a brittle fracture should be concerned in hydrostatic
strength test (165h) at 80°C. If a test piece fails
in a ductile mode in less than 165h, a retest shall
be performed at a lower stress and a new minimum failure
time selected follow table.
