Usage of ASTM A 53 Grade A / B / C Pipes
Usage of ASTM A 53 Grade A / B / C Pipes
(OP)
Dear All,
I am very much confused when to use ASTM A 53 Grade A / B / C Pipes. I know that the basic difference between various grades is in the percentage of Carbon & Magnesium if I'm not mistaken. So please help me out of this.
Thanks in advance................

You shuold choose the most commonly-used pipe grade that meet the guidelines that should be used when selecting the pipe material like:
- Special welding procedures
- allowable stress value (according B31.3)
- Service
- Resistance to Bright Fracture
- Corrosive Hydracarbon Service
Excessive wall tickness requires use of Grade B normally, but for example for use pipe with higher allowable design stress you should use another pipe material grade.
Which are the guidelines you have considered to choose ASTM A 53 ? Why not A106 Gr B ? Or API 5L-X52 ? They are quite the same and normally used for the the same service.

I know that you meant, "Resistance to Brittle Fracture".
Agreed, though. Not sure I would be inclined to use A-53-A/B/C if A-106 was available unless the job was extremely cost-sensitive.

I've heard that A53 with "galvinezed" finish is commonly used for fuel tanks piping systems (underground or above) which will add corrosive resistance.
I think you cannot use SA53 for Section I BEP (B31.1) because of code, and also not recommended to use for tubes inside Thermal Fluid Heaters subject to high temperatures.

Type "S" is seamless. Type "E" is ERW, and at 2"NPS and larger, every inch of the seam is 'supposidly' Eddy-current tested. "Supposidly" because I have personally Ultrasound - shearwave evaluated ERW seams and found lack-of-fusion on the ID, the OD, and sometimes both. Any properly calibrated Eddy-Current machine would have found all of these conditions, ID or OD. So there are pipe mills that will sell you junk. Don't buy from 3rd world countries - ever. [coughCHINAcough] Unless you don't mind leaks. There's a reason that some countries can sell a product cheaper than domestic, after shipping it cross-country, then trans-ocean, then cross-country.
