	Dear all, In purchasing a pipe API 5L, is it mandatory to stated either the pipe is PSL 1 or PSL 2? For PSL 2, is it mandatory to stated the delivery condition for the pipe which are either it is R (as-rolled), N(normalizing forming) or Q(quenching & tempered)? Really appreciate if somebody can tell me the differences between all delivery condition mentioned & how to decide which one to select. thank you very much..!

	PSL defined as Product Specification Level in API 5L , yes it is mandatory to stencil on pipe surface in addition with below for both case PSL1 & PSL2 1) Manufacturer Name - AB CO 2) Pipe Specification - API 5L 3) Specified Dimension (outside x sp. wall thickness) - 14" x 0.375" 4) Grade and class - Gr A 5) Product Specification Level - PSL1 or PSL2 6) Process of Manufacture - seamless (S),welded(W) 7) Heat treatment - Normalized and tempered (NH) 8) Test Pressure - 1500 PSI example - ABCO API 5L 14" x 0.375 B PSL2 S NH 1500PSI PSL 2 is more stringent requirement as compare to PSL1 , in PSL2 charpy test is mandatory, tensile strenth and chemical composition is more as compare to PSL1 with Regards

	While ordering a pipe following informations should be metioned as a Minimum 1. Pipe Size in ND 2, Pipe Material with Grade or Tensile Strength 3. Thickness or Schedule 4. End Connection BE or PE 5 LENGTH : 6 ( SRL ) OR 12 ( DRL) 6 Applicable API STD if Line Pipe 7 PSL 1 or PSL 2 These informations should be treated as enough Regards , Naved Mahdi
