API 5L Steel Line Pipe Plate

Whakaahuatanga Poto:

Pipeline maitai Ko te ahua o te pereti maitai whakamahia mo pipelines, te nuinga whakamahia i roto i te hanga o paipa paipa mo te hinu me te hau māori, me te waro me te hanga slurries rauemi.Ko te maitai e kore e hiahiatia anake te kaha compressive tiketike, engari ano hoki e hiahia ana tiketike iti pāmahana uaua me te weldability pai.

Hua Whakataki

Ko te maitai paipa hou o tenei wa ko te waro iti-iti-iti-iti-iti ranei te miihini miihini, he hua he mea hangarau teitei me te uara taapiri.Ko te nuinga o nga whakatutukitanga hangarau hou i roto i te mara whakarewa i roto i nga tau 20 kua pahemo kua whakamahia ki te hanga i te rino paipa.Ko te ahua whanaketanga o te miihini paipa he nui te diameter o te paipa, te kawe hau nui te pehanga, te whakamatao nui, te taiao whakamahi waikura nui, me te matotoru o te pakitara paipa o raro.Na reira, me whai kaha teitei te paipa paipa hou, te iti o te paanga o Bauschinger, te kaha me te kaha o te pakaru, te iti o te ihirangi waro weld me te pai o te weldability, me te aukati ki te pirau HIC me te H2S.

Ka whakamahia te pereti rino paipa ki te hanga paipa raina paiherea, na te mea he mea hanga nga putorino raina ki te pae porohita, ehara i nga pereti rino.Kei te whakamahia te pereti matotoru reo ki te hanga putorino paiherea whiri totika pakitara, a ka whakamahia te maitai kowiri ki te whakaputa putorino paiherea (ERW) hiko me te putorino arc paiherea (SSAW).I enei wa, ka nui noa atu nga kaihoko e hiahia ana ki te pereti rino paipa ki te whakaputa i nga putorino raina na te mea ka taea te whakamahi i nga pereti rino ki te hanga paipa diameter nui ake, hei taapiri, ko te utu o nga paipa paipa he iti ake i tera o nga paipa kore.

Raina paipa maitai pereti he rauemi matua mo te hanga o te paipa raina ERW, LSAW raina paipa, SSAW paipa raina, e whakamahia ana i roto i te hanga raina paipa i roto i te hinu, hau me te wai kawe, ka taea te whakamahi i te reira i roto i te hanga pehanga hanga tuku wai.

Te tino iti o te pāmahana Arctic, te taumahatanga i roto i te moana hohonu, te pāpāho waikawa: ahakoa nga ahuatanga tino kino kare he paanga kino ki o tatou papa riipene.Ka taea e nga papa raina paipa te mahi i te hohonutanga ki te 2,800 mita i raro i te mata o te moana.

Ka whakaekea ano e matou he pereti rino o waho o te takutai me te pereti awhi-atete ki te waikura mo nga tono teitei mo te tono hau kawa.I te mea he tohunga mo nga hangarau hurihuri hiko thermo hou me te whakamahana tere, kei roto matou i nga kaiarahi umanga o te ao.
