Pipe wall thickness problem
Thread Content
Can the wall thickness of the pipeline be determined based on the pressure level LB (equivalent to PN) and pipeline NPS (equivalent to DN)? The standard is ASTM A312. I also wrote a Standerd weight pipe! Please give me some advice. Thanks! This post was last edited by rishionli on 2009-4-16 13:25 ]
Different standards will have different wall thicknesses, which cannot be determined and the wall thickness should be determined by the SCH grade of the pipeline. This post was last edited by tekchina on 2009-4-16 12:32 ]
The standard is ASTM 312. But the SCH level is not indicated. Is there any way to check it? ?
Sch=p/ * 1000 in formula: p-indicates the design pressure, MPa, σ-indicates the allowable stress of the material at the design temperature, MPa
Also wrote a standard weight tube
With the standard ASTM A312, and Standerd weight pipe, the wall thickness can be found.
But in the A312 standard, there is no mention of Standard weight pipe? ? ? Is there any other thing or standard for this? For example, how much does Standard weight pipe represent SCH? ? ? Something like that? ? ?
How to check? What does a standard weight tube stand for? ? ?
SCH does not have another grade series STD, XS, XXS Example 1" pipe STD 0.133 Inch
