Hot-Finishes

Seamless line pipe is produced to comply with the specifications API 5L PSL1 and PSL2, ASTM A106 and ASTM A53.

Steel Grades
Three basic steel grades are used for the production of the different grades of material in the API 5L specification. The main chemical elements will comply with the maximum limits alongside.

Chemical Composition API 5L (PSL 1)

GRADE	C	Mn	S	P
B	0,20%	1,05%	0,030%	0,030%
X42	0,20%	1,05%	0,030%	0,030%
