Ikhwalithi enhle yase-China Hot DIP Sch40 A53 API 5L Gr. B Engenamthungo/Evunguzayo Eshiselwe /ERW/Ipayipi Lensimbi Lekhabhoni Elingaphekiwe
Uhlolojikelele
Sizokwenza umzamo womuntu ngamunye ukuze ahluke futhi afaneleke, futhi sisheshise izinyathelo zethu zokuma ngaphakathi kwerenki yamabhizinisi asezingeni eliphezulu emhlabeni wonke kanye nawobuchwepheshe obuphezulu be-A53 Gr. B Engenamthungo/Eshiselwe Ipayipi Lensimbi Lekhabhoni, Siyakwamukela ukuthi uvakashele imboni yethu futhi sibheke ngabomvu ukusungula ubudlelwano bebhizinisi obunobungane namakhasimende ekhaya naphesheya maduze. Yonke imikhiqizo yethu nezisombululo zihambisana nezindinganiso zekhwalithi zamazwe ngamazwe futhi zaziswa kakhulu ezimakethe ezihlukahlukene emhlabeni jikelele. Uma unentshisekelo kunoma yimiphi imikhiqizo yethu noma ungathanda ukuxoxa nge-oda langokwezifiso, khumbula uzizwe ukhululekile ukusithinta. Besibheke ngabomvu ukwakha ubudlelwano bebhizinisi obuphumelelayo namakhasimende amasha maduze nje.
I-ASTM A53 icacisa izimfuneko zamapayipi ensimbi angenamthungo/ashiselwe amnyama namadiphu ashisayo ukuze asetshenziswe ngokujwayelekile. Insimbi esohlwini olusezingeni kumele icutshungulwe esithandweni somoya esivulekile, ioksijini ye-alkaline noma isithando somlilo sikagesi, futhi kufanele ibe nezidingo zamakhemikhali ezilandelayo: i-carbon, i-manganese, i-phosphorus, isulfure, ithusi, i-nickel, i-chromium, i-molybdenum ne-vanadium. Ipayipi kufanele libe ngaphandle komthungo noma elishiselwe. Ukuhlolwa kwe-tensile, ukugoba kanye nokucaba kufanele kwenziwe ukuze kuqinisekiswe ukuthi kufanele kuhlangabezane nezakhiwo ezijwayelekile zemishini. Ukuhlolwa kwengcindezi ye-Hydrostatic kuzokwenziwa, futhi akukho ukuvuza nge-weld noma umzimba wepayipi. Ukuhlolwa kukagesi okungabhubhisi kufanele kwenziwe ukuze kuqinisekiswe ukuthi umthamo ophelele wepayipi kufanele uhlangabezane nezinga. Uma kuthathwa kudingekile ukuze kuqinisekiswe ukuthi ipayipi lihlangabezana nezidingo ezishiwo, umthengi unelungelo lokwenza noma yikuphi ukuhlola nokuhlola okucaciswe kulokhu kucaciswa.
I-ASTM A 53 ilungele izinhlelo zamapayipi okucindezela, amapayipi amapayipi kanye namapayipi enhloso evamile ezingeni lokushisa elingu-350 degrees. Phakathi kwazo, ibanga lensimbi le-Gr.B yilona elisetshenziswa kakhulu, ngamandla alo aqinile ≥ 415 (MPa) namandla esivuno ≥ 240 (MPa).
Isicelo
Isetshenziselwa Ngokuyinhloko izingxenye zamandla nengcindezi, futhi ngenjongo evamile yamapayipi omusi, amanzi, igesi nomoya.
