ASTM API 5L GR A seamless and welding steel pipe processes requiring validation are the following:
1.For API 5L GR A seamless, as-rolled pipe: final reheating practice and hot sizing or stretch reducing; if applicable, upsetting, cold finishing;
2.For API 5L GR A seamless, heat-treated pipe: heat treatment;
3.For electric-welded, as-rolled API 5L GR A pipe: sizing and seam welding; if applicable, seam heat treatment and upsetting;
4.For API 5L GR A electric-welded, heat-treated pipe: seam welding and full-body heat treatment;
5.For SAW and COW API 5L GR A pipe, non expanded: pipe forming, seam welding, repair welding; if applicable, heat treatment;
6.For API 5L GR A SAW and Cow pipe, expanded: pipe forming, seam welding, repair welding, expansion.
