No doubt that there is difference between ERW steel pipe and HFW steel pipe. The former is made through low or high frequency resistances Electric Resistance. However, for the latter, it is specially for high-frequency electric resistance welding.
Here is the question: What kind of requirements would be allowed into ERW steel pipe’s process?
There are untold steel pipes with different standards could be produced by ERW process. And for clients, they may just need some common standards in pipelines. So we would like to list them for customers to choose.
Stainless steel ERW pipe/tube standards and specifications
ASTM A269 stainless tube
ASTM A312 Stainless pipe
ASTM A270 sanitary tubing
ASTM A790 ferritic/austenitic/duplex stainless pipe
Carbon steel pipe in ERW
ASTM A53 Grade B and A (and Galvanized)
ASTM A252 pile pipe
ASTM A500 structural tubing
EN 10219 S275, S355 pipe
ASTM A134 and ASTM A135 pipe
API ERW Line pipe
API 5L B to X70 PSL1 (PSL2 shall be in HFW process)
API 5CT J55/K55, N80 casing and tubing
For example, Threewaysteel pipe company can supply ERW API 5CT, ERW Steel Pipe, API 5CT Pipe which also in the common category of ERW steel pipe.
