Iithegi zeMveliso

I-L360 Pipeline Steel, Injongo: I-API SPEC 5L-2011 (Inkcazo yoMbhobho), ephuhliswe kwaye ipapashwe yi-American Petroleum Institute, isetyenziswa kwihlabathi jikelele.Umbhobho: Ukuthutha i-oyile, irhasi okanye amanzi ukusuka emhlabeni ngemibhobho ukuya kwishishini leoli nerhasi.Umbhobho wombhobho uquka umbhobho ongenamthungo kunye newelded iindidi ezimbini, isiphelo sombhobho sinesiphelo esisicaba, isiphelo esinentambo kunye nesiphelo sosokethi;Imowudi yokudibanisa i-welding yokuphela, uxhumano lwe-hoop, uxhumano lwe-socket kunye nokunye.Izinto eziphambili ityhubhu yi-B, X42, X46, X56, X65, X70 kunye nezinye ibakala lensimbi.Inkampani yethu iphumelele isatifikethi se-API (API 5CT kunye ne-API 5L) ngo-Agasti ka-2009.

I-L360 Pipeline Steel, i-API SPEC 5L GB/T9711.1 GB/T9711.2 ISicelo soMgangatho weSizwe saseTshayina: Imibhobho yokuhanjiswa kweoksijini, amanzi kunye neoyile kwishishini le-oyile negesi yendalo B, X42, X52, X60, X65, X70 L245 L290 L320 L360 L390 L450 L485

Kunye nophuhliso umbhobho ipleyiti yentsimbi ubuchwepheshe kunye nenkqubela umbhobho odityanisiweyo ukwenza, iteknoloji welding, uluhlu lwesicelo umbhobho kunye umbhobho oludityanisiweyo ekwandiseni ngokuthe ngcembe, ingakumbi ubukhulu becala umbhobho odityanisiweyo scope iklasi inzuzo ebonakalayo ngakumbi, kunye neendleko izinto, umbhobho odityanisiweyo uye wagqwesa kwintsimi yombhobho womgca, othintela uphuhliso lwentsimbi engenamthungo yombhobho womgca wentsimbi.Ngo-2004, imveliso yombhobho ongenamthungo imalunga ne-400,000 t, ibakala lentsimbi libandakanya i-X42-70, kwaye iintlobo zemibhobho yonxweme kunye nombhobho ongaphantsi kwamanzi.

Ukuveliswa kombhobho wentsimbi yomgangatho ophezulu wamkela inkqubo yonyango yokufudumeza i-microalloying, iindleko zemveliso yentsimbi engenamthungo yombhobho ngokucacileyo ingaphezulu kunombhobho odityanisiweyo, kunye nophuculo lomgangatho wentsimbi, onjenge-X80 nangaphezulu komda wemibhobho yomgangatho wentsimbi olingana nekhabhoni. , inkqubo eqhelekileyo yombhobho ongenamthungo kunzima ukuhlangabezana neemfuno zabasebenzisi;Umenzi ngamnye wombhobho we-alloy we-12Cr1moV wenza umsebenzi wophando lwezenzululwazi ukuze kuphuculwe ukuxhathisa kokubola kombhobho wepayipi kunye nokusebenza okuzinzileyo kwimekobume yobushushu obuphantsi kunye nophezulu.
