Umdwebo Wemikhiqizo
Amazinga Okusebenza
1.Dizayina futhi wenze ngokuvumelana ne-API 602,BS5352,ANSI B 16.34
2.Uxhumano luphela kusukela ku-:
1) Ubukhulu be-Socket weld buhambisana ne-ANSI B 16.11, JB/T 1751
2) Ubukhulu beziphetho zesikulufa buhambisana ne-ANSI B 1.20.1,JB/T 7306
3)I-Butt-Welded ihambisana ne-ANSI B16.25,JB/T12224
4)Iziphetho ezicashile zihambisana ne-ANSI B 16.5,JB79
3. Ukuhlolwa nokuhlolwa kuhambisana nalokhu:
1)API 598,GB/T 13927,JB/T9092
4.Izici zesakhiwo:
Ibhonethi eboshiwe, isikulufu sangaphandle nejoka
Ibhonethi eshiselwe, ama-scres angaphandle kanye nejoka
5.Izinto ezisetshenziswayo zihambisana ne-ANSI/ASTM
6.Izinto ezibalulekile:
I-A105,LF2,F5,F11,F22,304(L),316(L),F347,F321,F51,Monel,20Alloy
