seamless steel pipe production process

　　General speaking seamless steel pipe production process can be divided into cold and hot rolled. Cold-rolled seamless steel pipe production process generally is more complicated than the hot-rolled, tube first to three roller rolling and extrusion to sizing test, if surface did not respond to the crack of tube through cutting machine for cutting, cutting growth is about one meter of blank. API5L pipes we can supply.And then into the annealing process annealing to use acidic liquid pickling, pickling should pay attention to surface a lot of blistering, if there are many foaming are produced to illustrate the quality of the pipe is not up to standard. Appearance of cold rolling seamless steel tube to short in hot rolling of seamless steel pipes, cold rolling seamless steel pipe wall generally thick than the hot-rolled seamless steel tube to small, but it seems than thick walled seamless steel pipe is brighter, the surface is not too much rough, caliber without too many burrs.
we can also supply oil screen pipe,  screen pipe , API5CT casing pipe,

oil casing pipe,slotted pipe etc.

different between PLS1 AND PLS2

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 steel 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.

PLS1	C ≤	Mn ≤	P ≤	S ≤	Si ≤	V ≤	Nb ≤	Ti ≤
B	0.28	1.20	0.030	0.030	-	-	-	-
PLS2	C ≤	Mn ≤	P ≤	S ≤	Si ≤	V ≤	Nb ≤	Ti ≤	CEpcm ≤
B	0.24	1.20	0.025	0.015	0.40	c	c	0.04	0.25
