14 Type of welding in PE pipes 1.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.

17 Sr. NoPropertyHDPE pipeP.V.C pipe 6Water Hammer Characteristics Better water hammer characteristics. Need higher diameter pipe lines to control surge pressures under similar conditions as that of HDPE. 7Highest C valueOver 150 with low frictional losses Around 130, more frictional losses need more pumping. 8Saving in Power cost Due to high C value low pumping cost Pumping costs are high due to high frictional losses 9Saving in labor cost Not necessary to prepare trenches Trenching & underground burying is must, increasing total cost. 10Velocity of flowHDPE pipe can be operated at higher velocities without derating the pipeline Flow velocities are lower than in HDPE due to lower C value.

18 Sr. No Propert y HDPE pipeP.V.C pipe 11Flexibili ty 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. 12LengthsSize 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. 13No. 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. 14Soil Settlem ent 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. Comparison between HDPE & PVC pipes
