Ukusetshenziswa kwe-JIS G 3454Ipayipi lensimbi le-Carbon ERW

Inqubo Yokukhiqiza ye-JIS G 3454CarbonIpayipi lensimbi le-ERW

Ukupakisha i-JIS 3454 Carbon ERW Steel Pipe

Ipayipi elingenalutho, i-coat emnyama noma i-dip eshisayo efakwe nge-zinc (eyenziwe ngokwezifiso);
Ezinyandeni ezinezihlilingi ezimbili zikakotini;
Zombili ziphela ngabavikeli bokugcina;
Isiphetho esingenalutho, isiphetho se-bevel (Lapho kudingwa umthengi kanye no-S≤22mm, umkhawulo wepayipi kufanele ubhobhodwe, izinga: 30° (+5°~0°), futhi ukushuba kodonga lwempande akwehliswa ngo-<2.4 mm.);
