Greetings everyone,
The general consensus is that pipe carries a + or - 12.5% wall thickness tolerance and has been around for 50 years.
I am currently dealing with SAWL 36 x .750 wall API 5L x52 pipe. I am being asked to prove that the + or - 12.5% wall thickness tolerance is in play for...
I am in possession of some 2" xs API 5L X52 PSL 2 Hyundai the producing mill did not report the CVN results on the MTR.
I am being told that 4" and below does not have to show results on the MTR. But I would need to prove this to our customer.
Table 22 gives the requirements per size for...
Hello Everyone,
Have a huge project calling for us to use floor stock inventory. The project calls for API 5L X52 PSL2 EN10204 Cert 3.2 with API 2B
The company is willing to allow us to use independent inspectors to meet the 3.2.
The MTR's that do not state API 2B we are going to certify the...
We are supplying pipe on a fast track job that requires material from stock.
Customer has requested ASTM A252 Gr 3 with 50 KSI min yield or better.
After placing the order they are requesting that all MTR's state "M" or modified due to the 50 KSI YS.
No where in the spec is there any...
Seeking Hydro of 100% SMYS @ 70KSI yield.
API 5L 46th ed. L450 (5LX65M) PSL 2 36" x .562wt Actual Yield on MTR is 72,300
Mill hydro'd at 2230# for 10 seconds
What hydrostatic test pressure would be required to meet 100% SMYS @ 70KSI yield?
As always, thanx everyone in advance.

API 45th edition calls out a wall tolerance on page 145 table J.4
it simply states
wall tolerance + - 0,7 (0.028)t
should I do a calculation here based upon my given wall to come up with a wall tolerance? If so what is the calculation?
OR
Is it my wall + or - .028
BTW my wall...
API 5L X52 PSL 2 30" O.D. X .875 wall
Permissable Mn is 1.65% MAX page 30 Table 5 (b)
MTR has Ladle and product Analysis
Ladle Mn 1.66
Product 1 1.60
product 2 1.60
Customer is rejecting due to the fact that the reported Ladle analysis is Mn 1.66%.
API clearly states in the very top of API...
