and what

PE80 SDR means

Cheers

But that's really easy

MDPE= medium density polyethylene

PE80 polymer formerly known as MDPE

PE100 formerly known as HPPE high performance polyethylene.

the number on the side example 41100311 is the range, shape code and size code.

41 = PE100
100= Electrofusion coupler
311=63mm


What the hell sdr 11 or 17 is I haven't a clue, maybe pressure rating and must find out

Cheers do it all.

Had a look on Google - see below for SDR.

For non-SDR-9 (standard diameter ratio) pipe having a nominal diameter of 7 mm (0.25'') and 10 mm (0.375'') the ratio of the specified nominal diameter to the maximum wall thickness of inner tubular HDPE core is 28 for 7 mm pipe, and 40 for 10 mm pipe the minimum wall thickness of PEX being 1.57 mm for 7 mm pipe, and 1.78 mm for 10 mm pipe. For SDR-9 pipe having a nominal diameter in the range from 13 mm (0.5'') to 152 mm (6'') the ratio of the specified nominal diameter to the maximum wall thickness of the inner tubular HDPE core is in the narrow range from 52 to 100, the minimum wall thickness of PEX being 1.78 mm for 13 mm pipe and 17.29 mm for 152 mm pipe.

Doitall - do you happen to know how to tell if blue MPDE PE80 water pipe has been attacked by uv ? Have a coil lying in the yard for 18months now uncovered and was wondering if it might be damaged ?

If its faded don't use it
