Where can I find the wall thickness specifications for national standard fittings? Also, where can I find the weight of pipe fittings with a certain wall thickness? GBT12459-2005 Steel Butt-Welded Seamless Fittings.pdf – I’ve searched everywhere but couldn’t find it. I hope experts can provide a specific way to locate it. I’ve read all of the replies on HAIYOU yet still haven’t found an answer; I hope someone can give me some guidance
Just shared GBT12459-2005 steel butt-welded seamless pipe fittings: http://bbs.hcbbs.com/thread-446669-1-1.html
It depends on the type of pipe you are using; for example, GB/T9711.1-1997 provides formulas for calculating the wall thickness and weight per unit length of spiral welded pipes.
There is a comparison table for outer diameter and wall thickness; SCHS applies to both fittings and pipes. The wall thickness can also be determined based on the pressure tolerance, while in the latter case it is determined according to the thickness of the pipe.
