ERW Ko te putorino maitai paiherea hiko-ātete, wehea Resistance paiherea paipa maitai ki te utu o te paipa maitai paiherea me te DC paiherea paipa maitai i roto i te rua puka.

AC fehokotaki'anga i roto i runga i iarere rerekē e wehea ki te fehokotaki'anga iti-auau, IF fehokotaki'anga, fehokotaki'anga o ultra-IF me te fehokotaki'anga teitei. Ko te nuinga o te wa e whakamahia ana mo te hanga i te putorino maitai angiangi-taiepa, i te putorino maitai ranei te matotoru o te pakitara, te taapiri auau teitei ki te whakapiri whakapiri me te whakapiri whakauru. DC fehokotaki'anga te tikanga whakamahia mo te iti-diameter putorino maitai. Na, i runga i te matawhānui, teitei-auau paipa paipa whakaurua i roto i te paipa ERW ko te tukanga fehokotaki'anga tiketike-auau ki te whakaputa paipa ERW. ERW Longitudinal mahi hua matatau i roto i te mara o te hinu me te hau rokiroki me te kawe, ārahitanga kounga, paipa maitai ohaoha ake.

Ko nga putorino rino SAW he poto o Submerged Arc Welding Steel Pipe, he mea whakamahi i te tukanga whakapiri arc ki te hanga rino, ka puta te mahinga i te kiato o naianei tino tiketike, te paparanga rere ki te aukati i te mate tere o te wera, me te kukū ki te rohe fehokotaki'anga. Ko te paipa arc kua rukuhia o te kounga teitei, te pai o te whakaputa, te pewa me te paowa he iti nga ahuatanga o te putorino pewa kua rukuhia e whakamahia nuitia ana i roto i nga oko pehanga, hanga putorino, kurupae, wai pehanga iti, mahi maitai. Ko nga hua matua o nga paipa rino SAW LSAW Steel Pipe, Longitudinally Submerged Arc Welding Steel Pipe LSAW steel pipe, ko te whakamahi i te hangahanga arc fehokotaki'anga o te paipa maitai tui tika.

Te rereketanga i waengaerwakitepaipa maitai

Ka rite ki ERW paipa maitai me SAW putorino maitai i roto i te putorino i roto i te hanga, fehokotaki'anga me te tukanga he rerekē, kia e rua momo o te putorino maitai i roto i te mahi i reira he etahi rerekētanga.

(1) He pai ake te kounga o te mata paipa rino ERW i te paipa paipa arc kua ruku ki raro, he maeneene, he maeneene, he ataahua te mata paipa rino ERW, he paipa rino SAW te whakakaha o roto, o waho hoki.

(2) ERW paipa maitai paiherea momo kohakore he iti iho i te kani paipa maitai. Ka kite i te paipa maitai me te whakarewa i whakatakotohia, he maha atu nga momo koha, hei taapiri i nga koha o te rōrahi, he mahanga waea-waea. ERW paipa maitai paipa kohakore anake waea-raina me te tika fehokotaki'anga, te tukanga tirohanga ngāwari ki te whai, me te kohakore i roto i te whakaata mōrahi i, kotahi te kore o implicit, ultrasonic whakaata i te kaha, ngāwari ki te kitea.

(3) ERW paipa maitai e pā ana ki kite paipa maitai i roto i te toenga ahotea ōwehenga he iti. I te mea he pai ake te rerekee o te putorino ERW i roto i te tukanga deformation, ka honoa te rahinga o muri o te oval papatahi, nga huringa poutū porotiti me te kaki, ka iti ake te ahotea o te putorino ERW. I kitea e nga whakamatautau tinana he rite tonu nga korero, he rite tonu te putorino ERW i muri i te werohanga i te tuaka, ko te axial me nga wehenga whakawhiti he iti ake te neke atu i te putorino paiherea arc kua rukuhia.

(4) ERW Pipe mahi katoa o te taua, ka riro koha te paipa, whakawa moka maitai, tukua fehokotaki'anga. Ko te paipa rino SAW e whakaaetia ana, me te mahi paipa putorino me te mahi katoa he rerekee, ko te waahi whakapiri ka kaha ki te pakaru i te waikura. Ko nga whakamatautau e whakaatu ana ko te ahotea waikura rohirohi whakamātautau ERW paipa tōrino submerged arc paiherea paipa roa atu i te ora.
