Specifications for ERW/HRW pipes with PWHT
Specifications for ERW/HRW pipes with PWHT
(OP)
Hi,
I am selecting welded pipe material for an offshore structure and came across a requirement that if ERW/HRW pipes are used they have to subjected to heat treatment to relief stresses caused by this welding technique.
I was wondering if the required heat treatment is there (by default) EN 10225 , EN 10210, EN 10219 and API 5L.

Many thanks for the response.
I am actually selecting the material based on the project specification.
The reason i raised the question is that one paragraph of the material specification stated that ERW pipes are not allowed, yet it called for the usage of several pipe grades of EN 10225 which are ERW pipes. So i was trying to figure out why.
