Seamless steel pipes china supplier
PIC-(Seamless steel pipes china supplier)
Our factory are professional in producing API5L PLS1/PLS2 line pipes Seamless steel pipes china supplier. We can according to API5L,ASME or GB to produce.
Standard: GB/T 8163, ASME, API5L
Standard: GB/T 8163, ASME, API5L
Material: ASTM A53/A106 GrB. API5L GrB. PlS1. 10#,20#,Q345 etc.
Outside Diameter: 8-630mm
Thickness: 1-40mm
API 5L seamless steel pipes, the line pipe have PLS1 and PLS2. PLS is the products standard brief name. It is also the quality grade. So when order the API pipes there should clear the material grade. It is pls1 or pls2. The difference between PLS1 And PLS2 is as the following:
1. The test method and chemical is different. PLS1 no need do the impact test. But PLS2 except steel grade X80, all the other steel grade need the full size on 0℃ the average figure, Vertical ≥41J Horizontal ≥27J. X80 pipes full size 0℃ Akv average figure is Vertical ≥101J Horizontal ≥68J.
2. The PLS2 line pipes need do the water pressure test by piece. While PLS1 no need do the UT. PlS2 need do the UT piece by piece.
3. PLS1 and PLS2 Chemical compare.
