What is a Seamless Pipe?
Seamless pipes are derived from solid steel that is in sheet or bar form and is formed into a solid round shape known as “billets” which are then heated and cast over a form such as a piercing rod to create a hollow tube or shell. These kinds of pipes are known for their ability to withstand pressure more efficiently in comparison to other methods of pipe manufacturing processes, as well as being fast and cost-effective. Seamless pipes are generally used in gas lines, as well as pipes that carry liquidseamless pipes are derived from solid steel that is in sheet or bar form and is formed into UNS
Main representative grades of duplex stainless steel
DSS can be generally divided into four categories:
Low alloy type -- the representative brand is UNS s32304 (23cr-4ni-0.1n)
PrEN value 24 ~ 25
Medium alloy type -- the representative brand is UNS S31803 (22cr-5ni-3mo-0.15n),
PrEN value 32 ~ 33
High alloy type -- the standard brand is UNS s32550 (25cr-6ni-3mo-2cu-0.2n),
PrEN value 38 ~ 39
Super duplex stainless steel type -- standard grades include UNS S32750 (25cr-7ni-3.7mo-0.3n),
PrEN value ＞ 40
