What does L245 SEAM(L) mean?
Thread Content
I would like to ask which expert knows what the letter \"L\" in \"L245 SEAM(L)\\" refers to when it comes to pipe materials
In SEAM(L), does L stand for the English word \"Line\", or does it have some other meaning?
Steel pipes are of two types: seam-type and seamless. There are very few pipes that are completely seamless; it’s impossible to have absolutely no seams at all – at least there are circumferential welds. Pipes with seams are called welded steel pipes, and these come in two varieties: straight-seam and spiral-seam. Check which type yours is; for the rest, you can look up information – it’s likely to be a straight-seam pipe
LGS is the abbreviation for Longitudinal Seam in pipeline materials; it refers to straight-seam welded pipes
