For example, PE2708 is a polyethylene with adensity cell class of 2 and a slow crack growth resistance cellclass of 7 as per Specification D 3350 with an 800psi designstress for water at 73.4F (23C).

Measurements of coiledpipe shall be made on a sample cut from the coil, and in caseof disagreement, conditioned per 6.3.NOTE 2Other factors, that is, installation compaction,
40、 static soilloading, and dynamic vehicular loads may increase the ovality; therefore,5 % was chosen as the limit for the amount contributed by manufacturing,packing, in-plant storage, and shipping. For further information, see (1).7(1) Before or during installation, coiled pipe larger than 3 in.IPS
41、(88.9 mm) shall be processed by the installer throughre-rounding equipment that corrects ovality to 5% or less.NOTE 3Ovality is a packaging condition that occurs when roundablepipe is wound into a coilthe pipe flattens out as it is coiled. Ovality iscorrected when joining equipment is applied to rou
