Non-seemless pipe is rolled from a flat piece of metal and welded lengthways to form the piping. Seemless pipe is extruded and has no seems and is generally stronger.
Pipes that have been welded (or melted) together.
coil welded type
High Frequency Welded Pipe
A CEW pipe stands for a cold drawn electrically wielded pipe. Pipes can be made in a number of ways. One such method is to make pipes from sheet steel. The sheet is cut to the required width and rolled along the length. The ends are to be joined so that is forms a pipe. When they are welded using resistance then they are called ERW pipes and when they are electrically welded they are cold drawn electrically welded pipes or CEW pipes.

Double submerged arc welded pipes has two types, one is spiral welded pipes, and the other is longitudinal welded pipes which are different from EFW pipes.

Heavy weight mild steel with screwed fittings bspt. == Normally galvanized pipes are not used for steam. Mild steel with screwed or welded fittings are the norm. Pressure and temperature are very important factors to be considered in what type of materials to be used. Steam even at low pressures can be extremely dangerous. Answer In hign temperature application nomally the alloy steel pipes are used ANSWER: Mild Steel Seemless pipes, thickness dependent on the pressure rating to be used.

This acronym means Helical Submerged Arc Welded pipes. They are also know as Spiral Submerged Arc Welded pipes. These specification of pipes are assembled via welding. They are mainly deployed for the transportation of oil and gas in some cases, water. Hope this helps.
The difference between seamless and welded (as it is commonly known) pipes is the welded joint along the longitudinal direction. Seamless pipes are manufactured by continuous extrusion process. Seamless pipes have greater bursting and tensile strength than the welded ones.
SAW PIPE = SUB MERGED ARC WELDED PIEP
Furnace butt welded pipe refers to the manner in which a pipe is to be welded. The skelp itself is heated to a specific temperature in a furnace. You would then weld the longitudinal seam forge. This is a method that works on fence posts or pipes required for low pressure services.
