Isevisi yase-China High-Temperature ye-ASTM A106 A53 Gra/API 5L Grb/A179 A192 Udonga Oluwugqinsi/I-Thin Wall Carbon Seamless Steel Tube/Galvanized Pipe
Uhlolojikelele
Sizama ukwenza kahle, sisekela amakhasimende", sithemba ukuba ithimba eliphezulu lokubambisana kanye nebhizinisi elibusayo labasebenzi, abahlinzeki kanye nabathengi, libona ukubaluleka kokwabelana kanye nokumaketha okuqhubekayo kweCarbon Steel Seamless Tube/Pipe, Ngaphandle kwalokho, inkampani yethu inamathela kukhwalithi ephezulu futhi izindleko ezithengekayo, futhi sethula nezinkampani ezinhle ze-OEM ezinkampanini eziningi ezidumile lapho sibhekene nokuncintisana kwezimakethe zomhlaba wonke, sethule isu lokwakha umkhiqizo futhi sabuyekeza umoya "wenkonzo egxile kubantu nethembekile", ngenhloso yokuthola ukuqashelwa emhlabeni jikelele. kanye nentuthuko esimeme.
I-ASTM A106 GR. B Ipayipi lensimbi engenamthungo linokusebenza okuhle kokushisela. Ngenxa yokuqukethwe okuphansi kwe-C, ngokuvamile asikho isakhiwo esiqinile esiqinile ngenxa yokushisela, futhi isihlanganisi esishiselwe sinepulasitiki enhle nokuqina. Yonke inqubo yokushisela ingathola i-welding ehambisanayo ehlangene ngaphandle kwezinyathelo ezikhethekile zobuchwepheshe.
I-ASTM A106 GR. I-B kanye ne-20# ziyefana ekwakhekeni kwamakhemikhali nasezimpahleni zemishini futhi zivame ukushintshwa enye nenye, kodwa umehluko ukhona, ikakhulukazi maqondana nezidingo zokusetshenziswa okunwetshiwe.Isibonelo, ukuthatha u-20# njengesibonelo, i-GB50316 ibeka ukuthi izinga lokushisa elincane lokusebenza ye-GB8163 20# ishubhu lensimbi ngu-19℃, kuyilapho i-ASMR B31.3 ibeka ukuthi izinga lokushisa elincane elisebenzayo elingu-A106 GR. Ishubhu lensimbi elingu-B lingu-29℃, futhi kunesimo sokungabi bikho kokuhlolwa komthelela. Yize kunomehluko ekucacisweni kwedizayini, isizathu esijulile umehluko wezinga lokulawula lokuqukethwe kwe-Mn. Umkhiqizi angase angazazi lezi zandiso. , kodwa umthengi kufanele aqaphele lo mehluko futhi azise umenzi ngezimfuneko ngesikhathi sokuthenga, ngaphandle kwalokho izinkinga zingase ziphakame ngaphansi kwezimfuneko eziqinile.
Isicelo
Ipayipi lensimbi engenamthungo yokusebenza okuphezulu kokushisa kwe-ASTM A106, efanelekile ukushisa okuphezulu
Ibanga Eliyinhloko
