Different Types of Stainless Steel Pipes Based on the Production Method

The technique of producing welded pipes from continuous coil or plate entails rolling the plate or coil in a circular section with the help of a roller or bending equipment. The filler material can be used in large-scale production. Welded pipes are less expensive than seamless pipes, which have an overall more cost-intensive production method. Although these production methods, namely welding methods are essential parts of stainless steel pipes, details of these welding methods won’t be mentioned. It could be a topic of another blog post of ours. Having said that, welding methods for stainless steel pipes commonly appear as abbreviations. It is important to be familiar with these abbreviations. There are several welded techniques, such as:
1.EFW– Electric fusion welding
2.ERW– Electric resistance welding
3.HFW– High frequency welding
4.SAW– Submerged arc welding (spiral seam or long seam)

Description:

Seamless cold drawn stainless steel pipes are made in accordance to ASTM A312 TP316 / 316L standards. The material of stainless steel pipe is available in dual grade which is SS316 / 316L which allows dual usage of tubes.
SS316 pipes are most supplied in high performance fluids application for its great corrosion resistance and for its ability to withstand higher pressure. Stainless steel pipe is available in one finishing, namely annealed and pickled.
The unit used in stainless steel pipes is Inch NB size range and thickness is in schedules (abbreviated as “SCH”). The unit SCH refers to the variation of thickness. There are three types of end connections for stainless steel pipes: plain end (PE), bevel end (BE), and threaded end (TE).
