ERW Steel Pipe is produced in sizes from 1/8 to 24 in NPS. ERW Steel pipe is produced from flat sheet metals. ERW steel pipe is first cold formed into a cylindrical shape and then welded longitudinally. both continuous welded and elctric resistance welded pipe are made by shaping rolls of coiled steel into cylindrical forms and welding along the longitudinal seams. Picture below shows the first step of forming strips into cylindrical shape and then fusing it together in 2nd step.

Manufacturing Of ERW Steel Pipe
There are many ways for the electric current to be used for welding the rolled strip. This includes revolving copper disc, fixed alloy Cu contacts and induction coils. These methods raise the temperature of the steel edge to 2600 deg F for effective welding. The rolling process exerts so much pressure that it creates a metal welded seam on the outside and inside. These weld seams are then removed during the finishing process. The welded pipe is heat treated, inspected and hydro tested.
ERW steel pipe is available in following common specs;
ASTM A53 ERW steel pipe
A135 ERW steel pipe
A252 ERW steel pipe
A500 ERW steel pipe
A795 ERW steel pipe
API 5L ERW steel pipe
API 5CT ERW steel pipe
Most common spec for welded pipe is A53 ERW steel pipeand API 5L ERW steel pipe.
