L360 paipa maitai tukatuka ritenga paipa kawe putorino
L360 Pipeline Steel, Kaupapa: API SPEC 5L-2011 (Pipeline Specification), i whakawhanakehia, i whakaputaina e te American Petroleum Institute, e whakamahia ana i te ao katoa.Pipepipe: Hei kawe hinu, hau, wai ranei mai i te whenua ma nga paipa paipa ki te umanga hinu me te hau.Ko te paipa paipa kei roto nga putorino tuitui me te paiherea e rua nga momo, he papatahi te pito o te putorino, te pito miro me te pito turanga;Ko te aratau hononga ko te mutunga fehokotaki'anga, hononga porowhita, hononga turanga me te aha.Ko te rauemi matua o te ngongo ko B, X42, X46, X56, X65, X70 me etahi atu karaehe rino.I tukuna e to maatau kamupene te tiwhikete API (API 5CT me API 5L) i Akuhata 2009.
L360 Pipeline Steel, API SPEC 5L GB / T9711.1 GB / T9711.2 Haina Paerewa Paerewa Hainamana: Oxygen, wai me nga paipa tuku hinu i roto i te ahumahi hinu me te taiao B, X42, X52, X60, X65, X70 L245 L290 L320 L360 L390 L450 L485
Ki te whanaketanga o te paipa paipa hangarau paraharaha me te ahunga whakamua o paipa paipa hanga, hangarau fehokotaki'anga, te whānuitanga tono o te putorino ki putorino paiherea i roto i āta whakawhänui, rawa i roto i te diameter nui paiherea putorino hōkai akomanga painga ake kitea, me te utu āhuatanga, paipa paiherea kua tino nui i roto i te mara o te paipa raina, e whakawhāiti te whanaketanga o te kowiri tira paipa raina tui maitai.I te tau 2004, he 400,000 t te putanga o te paipa tuitui, ko te karaehe rino ko te X42-70, ko nga momo he paipa ki uta me te paipa o raro.
Ko te hanga o te putorino paipa paipa maitai teitei e tango ana i te tukanga maimoatanga whakamahana whakawera microalloying, ko te utu hanga o te kowiri tira putorino tuitui he tino kitea ki runga ake i te putorino paiherea, me te whakapai ake i te karaehe rino, penei i te X80 me runga ake i te tepe paipa paipa rino o runga i te waro rite. , he uaua ki te whakatutuki i nga whakaritenga o nga kaiwhakamahi te tukanga tikanga o te paipa kore;Ko ia kaihanga putorino koranu 12Cr1moV kei te mahi rangahau putaiao kia pai ake ai te aukati i te waikura o tana putorino paipa me te pai o te mahi i roto i te taiao iti me te teitei.
