Welded pipe:
 Welded Pipes are manufactured from Plate or continues Coil or strips. To manufactured
welded pipe, first plate or coil is rolled in the circular section with the help of plate
bending machine or by a roller in the case of continues process. Once the circular
section is rolled from the plate, the pipe can be welded with or without filler material.
Welded pipe can be manufactured in large size without any upper restriction. Welded
pipe with filler material can be used in the manufacturing of long radius bends and
elbow. Welded pipes are cheaper with compared to the seamless pipe and also Weak
due to the weld joint.
