Kev faib tawm ntawm cov txheej txheem square tube
Lub raj square tau muab faib ua cov txheej txheem ntau lawm: kub-dov seamless square raj, txias rub-tawm seamless square raj, nyem seamless square raj, thiab vuam square raj. Ntawm lawv, lub vuam raj tshuaj muab faib ua: (a) raws li cov txheej txheem -arc vuam square tube, tsis kam vuam square tube (siab zaus, tsis tshua muaj zaus), roj vuam square raj, qhov cub vuam square tube Slim vuam raj, kauv vuam square tube
Kev faib tawm ntawm cov khoom siv
Cov yeeb nkab square yog muab faib los ntawm cov khoom siv: dav dav carbon steel square raj, qis alloy square raj. General carbon steels muab faib ua: Q195, Q215, Q235, SS400, 20 # steel, 45 # steel, thiab lwm yam. Cov hlau tsis tshua muaj hlau tau muab faib ua Q345, 16MN, Q390, ST52-3, thiab lwm yam.
Kev faib tawm ntawm Founded Management Standards for Production Standards
Kev tswj hwm square tau muab faib ua cov qauv tsim: lub teb chaws cov qauv, cov qauv niaj hnub, British-based square tswj, US cov qauv, European qauv, thiab tsis yog-tus qauv square tswj.
Classification ntawm square tube seem nto
Lub raj square yog cais raws li cov duab ntawm seem: (1) Tej yam yooj yim seem square tube -square square tube, rectangular square tube (2) complex seem square raj - paj -zoo li tus square raj, qhib square raj, ripple -shaped square. tube, thiab alien square tube.
Kev faib tawm ntawm kev kho deg ntawm lub raj square
Lub raj square yog kho nrog kev kho deg: kub-dip galvanized square raj, electro-galvanized square raj, roj-coated square raj, thiab pickled square raj.
Kev faib tawm ntawm cov kav dej square
