About PE63,PE-80 & PE-100
The PE pipe materials are classified with reference to their strength when subjected to internal hydrostatic pressure at 20°C during service life of at least 50 year. The minimum required strength (MRS) expressed in bar is used for designation of the pipe. Therefore you will find designation from PE-32, PE-40, PE-63, PE-80 & PE-100

Type of welding in PE pipes1. Butt Welding :- The welding procedure involves accurate machine planning of the
pipe ends followed by heating to the melting point of the pipe ends, which are then jointed together under pressure. The heating and cooling time, temperature and pressure are adjusted so that the physical properties of the original material is retained.
2. Fusion Welding:- Use of this type welding, provided similar heating on outer surface of the pipe and inner surface of the fittings by heating devise then
overlap both surface by external force. This technique use only small for diameter pipes.
3. Electro fusion welding:- The fittings is basically a double socket coupler with an electrical heating element within the bore. Two connection terminals are externally accessible for application of electrical heating energy to the element. When the two squared and scraped pipes ends are inserted into the coupler and the current is applied via a control box to the terminals the heating generated in the element fuse the two jointing surface together.

Sr. No Property HDPE pipe P.V.C pipe
6 Water Hammer Characteristics
Better water hammer characteristics.
Need higher diameter pipe lines to control surge pressures under similar conditions as that of HDPE.
7 Highest C value Over 150 with low frictional losses
Around 130, more frictional losses need more pumping.
8 Saving in Power cost
Due to high C value low pumping cost
Pumping costs are high due to high frictional losses
9 Saving in labor cost
Not necessary to prepare trenches
Trenching & underground burying is must, increasing total cost.
10 Velocity of flow HDPE pipe can be operated at higher velocities without derating the pipeline
Flow velocities are lower than in HDPE due to lower C value.

11 Flexibility
Flexible, can be bent over curves during installation requiring very few fittings at site. Undertaking installations do not crack the pipes.
Very limited flexibility and require lot of bends and fittings for installation. Undertaking installation can crack the pipe.
12 Lengths Size up to 110 mm can be supplied in number of combination like 6 mtr, 12 mtr & coil form.
Comes only in straight lengths of max 6 mtrs.
13 No. of Joints
Less no of joints as up to 110 mm, pipes can be supplied in coils form, reducing chances of leakage too.
As PVC pipe can not be coiled Lots of joints required for installation.
14 Soil Settlement
Being flexible, adjust itself to soil settlement and hence no cracking of joints .Ideal material in earthquake prone areas.
Partially flexible adjust itself to soil settlement only at moderate loads and may lead to crack of joints .Highly prone to cracking in earthquake prone areas.
