Ikhwalithi Ephakeme yaseChina Iqembu lomkhiqizo Elingenamthungo/ERW elishiselwe I-Stainless/Carbon/Alloy Galvanized Square/round Boiler Engenamthungo/Ipayipi Lensimbi Lokushintshanisa Ukushisa
Uhlolojikelele
Umgomo wethu uwukuthuthukisa njalo sibe umphakeli oqanjiwe wamadivayisi edijithali nokuxhumana ngobuchwepheshe obuphezulu ngokunikela ngomklamo ongezwe amanani, ukukhiqiza okusezingeni lomhlaba, kanye namakhono okukhanda we-Seamless/ERW welded Stainless/Carbon/Alloy Galvanized Square/round Seamless Steel Pipe, Okuthengiswayo kwethu kuthunyelwe eMid East, Europe, Korea, Vietname, Iraq, Russia nakwamanye amazwe. Sibheke phambili ukudala ukubambisana okuhle nokuhlala isikhathi eside kanye nawe ekusaseni elizayo elibonakalayo! Sinezixazululo ezingcono kakhulu kanye nokuthengisa okukhethekile kanye nethimba lezobuchwepheshe.Ngokuthuthukiswa kwenkampani yethu, siyakwazi ukuletha amakhasimende imikhiqizo ehamba phambili, ukusekelwa okuhle kobuchwepheshe, isevisi ephelele yangemva kokuthengisa.
Isicelo
Isetshenziselwa Ngokuyinhloko izingxenye zamandla nengcindezi, futhi ngenjongo evamile yamapayipi omusi, amanzi, igesi nomoya.

A Ubude obuncane begeji engu-2in. (50mm) izonqunywa ngefomula elandelayo:
e=625000(1940)A0.2/U0.9
e = ubude obuncane begeji engu-2in. (50mm), iphesenti lifinyezwa ku-0.5% eseduze;
A = Ibalwa ngokuhambisana nobubanzi obushiwo bangaphandle beshubhu lokuzisholo noma ububanzi besampula obuqinile kanye nogqinsi olucacisiwe lodonga, futhi lazungezwa endaweni eseduze yesigaba esiphambanayo yesampula eqinile engu-0.01 in.2 (1 mm2), futhi Iqhathaniswa no-0.75in.2 (500mm2), kuye ngokuthi yikuphi okuncane.
U = amandla amancane aqinile abekiwe, i-psi (MPa).
B Ngokuhlanganiswa okuhlukahlukene kosayizi abahlukene bezibonelo zokuhlolwa kwe-tensile namandla anqunyiwe abekiwe, ubude obuncane obudingekayo buboniswa kuThebula X4.1 noma kuThebula X4.2, ngokuya ngokusebenza kwakho.
Isidingo Sokuhlola
Ukuhlolwa kwe-tensile, ukuhlolwa kokugoba, ukuhlolwa kwe-hydrostatic, ukuhlolwa kukagesi okungonakalisi kwama-welds.
