Emkhakheni weamapayipi ensimbi, izindinganiso zamapayipi ensimbi othungelwe nge-arc abalulekile abalulekile.Elinye lamazinga yi-GB/T3091-2008, ehlanganisa izinhlobo ezahlukene zamapayipi ensimbi othungelwano oluqondile, njengokumelana ne-high-frequency.amapayipi ensimbi ashiselwe (ERW)., i-arc engaphansiamapayipi ensimbi ashiselwe (SAWL).kanye namapayipi ensimbi ahlanganiswe ne-spiral seam arc welded (SAWH).)Ipayipi Lensimbi.
Ngokuhamba koketshezi olunomfutho ophansi, i-GB/T3091-2008 iphinde ibeke ukusetshenziswa kwe-amapayipi ensimbi ashiselwe.Lawa mapayipi ensimbi ashiselwe ngogesi, awaziwa kakhulu ngokuthi amapayipi amhlophe, asetshenziselwa ukuthutha amanzi, igesi, umoya, uwoyela, isitimu esishisayo, amanzi afudumele, njll. Ukucaciswa kwala mapayipi ensimbi kuvezwa ngobubanzi obungajwayelekile, kanye nobubanzi obungaphandle nodonga. ubukhulu buhambisana nemithethonqubo ye-GB/T21835.Ngaphezu kwalokho, ubude bepayipi lensimbi bungasukela ku-300mm kuya ku-1200mm, futhi bungakwazi ukulungiswa ubude noma ubude obuphindwe kabili.
Uma kuziwa ezindabeni zekhwalithi, izinga lokushisa phakathi nenqubo yokubhoboza linomthelela omkhulu.Amapayipi ensimbi yokwandisa okushisayo ngokuvamile afinyelela emazingeni okushisa azungeze u-1200°C, nakuba okuqukethwe kwekhabhoni nezinto eziyingxubevange kunganciphisa izinga lokushisa kancane.Esinye isici esibalulekile okufanele sicatshangelwe ukunciphisa inani lesilinganiso ngesikhathi sokugoba okushisayo, njengoba lokhu kungase kuthinte impilo yamathuluzi kanye nekhwalithi yendawo.
Ukusebenza kokushisisa kuyinqubo ebalulekile ekukhiqizeniIpayipi lensimbi elingu-16Mn eliqondile.Njengoba ukucubungula okuningi kwenzeka esimweni esishisayo, ukulawula okunembile izinga lokushisa lokushisa kubalulekile ukuze kuqinisekiswe ikhwalithi yomkhiqizo wokugcina.
Ukugcina izinga namazinga, ukulawula izinga lokushisa ngesikhathi sokubhoboza kubalulekile.Ipayipi lensimbi lomthungo oqondile elijwayelekile le-GB/T3091-2008 licacisa ukuchezuka okuvumelekile ngosayizi, umumo, isisindo kanye nobubanzi bangaphandle nokuqina kodonga.Ukuchezuka okuvumelekile kogqinsi olujwayelekile lodonga kuyahlukahluka ngokuya ngebanga lokuchezuka, kusukela ku-S1 kuye ku-S5, futhi ibanga ngalinye licacisa amaphesenti ahambisanayo kanye nokuchezuka okuncane.
Ngaphezu kokubekezelelana okulinganiselwe kodonga olujwayelekile, ukubekezelelana kokuqina kodonga okungajwayelekile nakho kucatshangelwa.Amaleveli okuchezuka (isb. NS1 kuya ku-NS4) ahlanganisa ukuchezuka kwephesenti elithile ukuze kuqinisekiswe ukulawulwa kwekhwalithi.Kumele kuqashelwe ukuthi u-S umelela ubukhulu bodonga lwepayipi lensimbi, futhi u-D umele ububanzi obungaphandle bepayipi lensimbi.
Ukuqinisekisa ukuthobela la mazinga kubalulekile ekukhiqizweni kwamapayipi enqwaba ensimbi ashiselwe i-arc esezingeni eliphakeme longitudinal submerged.Ngokugcina ukulawula okunembile kwezinga lokushisa nokunaka ukuchezuka okuvumelekile, abakhiqizi bangahlangabezana nokulindelwe ngamakhasimende futhi banikeze ngemikhiqizo ethembekile nehlala isikhathi eside.
