Ipayipi lensimbi ye-L360 yepayipi yokucubungula ngokwezifiso ipayipi lokuthutha
I-L360 Pipeline Steel, Injongo: I-API SPEC 5L-2011 (Ukucaciswa Kwepayipi), eyakhiwe futhi yanyatheliswa yi-American Petroleum Institute, isetshenziswa emhlabeni wonke.Ipayipi: Ukuthutha uwoyela, igesi noma amanzi ukusuka emhlabathini ngamapayipi ukuya embonini kawoyela negesi.Ipayipi lepayipi lihlanganisa ipayipi elingenamthungo nelishiselwe izinhlobo ezimbili, ukuphela kwepayipi kunomkhawulo oyisicaba, umkhawulo ocushiwe kanye nokuphela kwesokhethi;Imodi yokuxhuma i-welding yokuphela, uxhumano lwe-hoop, uxhumano lwesokhethi nokunye.Izinto eziyinhloko ze-tube yi-B, X42, X46, X56, X65, X70 kanye nelinye ibanga lensimbi.Inkampani yethu yaphasa isitifiketi se-API (API 5CT ne-API 5L) ngo-Agasti 2009.
L360 Pipeline Steel, API SPEC 5L GB/T9711.1 GB/T9711.2 China National Standard Application: Oxygen, amanzi namafutha ukulethwa amapayipi embonini kawoyela negesi yemvelo B, X42, X52, X60, X65, X70 L245 L290 L320 L360 L390 L450 L485
Ngokuthuthukiswa kobuchwepheshe bepuleti lensimbi yepayipi kanye nenqubekela phambili yokwakhiwa kwamapayipi ashiselwe, ubuchwepheshe bokushisela, uhla lwesicelo sepayipi ngepayipi elihlanganisiwe ekwandeni kancane kancane, ikakhulukazi izinzuzo zesigaba esikhulu sepayipi elihlanganisiwe zibonakala kakhudlwana, nezici zezindleko, ipayipi elishiselwe bekulokhu kuvelele emkhakheni wepayipi lomugqa, okhawulela ukuthuthukiswa kwepayipi lensimbi engenamthungo.Ngo-2004, ukukhiqizwa kwepayipi elingenamthungo kulinganiselwa ku-400,000 t, izinga lensimbi lihlanganisa i-X42-70, futhi izinhlobo zingamapayipi asogwini kanye nepayipi elihamba ngaphansi kolwandle.
Ukukhiqizwa kwepayipi lepayipi lensimbi esezingeni eliphezulu kusebenzisa inqubo yokwelapha yokushisisa nge-microalloying, izindleko zokukhiqizwa kwepayipi lensimbi engenamthungo ngokusobala ziphakeme kunepayipi elishiselwe, futhi ngokuthuthukiswa kwezinga lensimbi, elifana ne-X80 nangaphezulu komkhawulo wepayipi lensimbi elilingana nekhabhoni. , inqubo evamile yepayipi engenamthungo inzima ukuhlangabezana nezidingo zabasebenzisi;Umkhiqizi ngamunye wamapayipi engxubevange ayi-12Cr1moV wenza umsebenzi wocwaningo lwesayensi ukuze athuthukise ukumelana nokugqwala kwepayipi lawo kanye nokusebenza okuzinzile endaweni yokushisa ephansi nephezulu.
