Semugadziri anotungamira mundima iyi,Iyo kambani Cangzhou Spiral Steel Pipe Group Co., Ltd.inonyatso kuomerera kune dzepasirese zviyero uye inyanzvi mukugadzirwa kwe electrofusion arc weldedspiral musono simbi mapaipikufukidza mamakisi mashanu. Iyi mhando yeASTM simbi pombiyakanyatsogadzirirwa kutakurwa kwezvinwiwa, magasi kana chiutsi, kuve nechokwadi chekushanda kwakachengeteka uye kwakanaka munzvimbo dzakasiyana-siyana dzekumanikidza uye dzakaoma.
Simba rekambani rinobva pakukura kwayo kukuru kwekugadzira kugadzirwa. Tine mitsara gumi nenhanhatu yesimbi yekugadzira pombi uye mitsara mina inorwisa-corrosion uye mitsara yekupisa yekupisa yekupisa, inokwanisa kugadzira pombi dzesimbi dzakatenderedzwa dzine madhayamita ekunze anotangira pa219 millimeters kusvika pa3500 millimeters uye kukora kwemadziro kusvika pa25.4 millimeters.
Zvigadzirwa zvayo zve "Wuzhou" brand hazvingotevedzere akawanda epasi rose zviyero seAPI Spec 5L uye EN 10219, asi zvakare zvinozadzisa zvizere zvinodikanwa zveakakosha zviyero zvakaita seASTM A139 uye ASTM A252.
Aya mapaipi esimbi eChinese anoteerana neASTM miyero ane akanyanya kupamhama mashandisirwo mamiriro. Iwo akashandiswa zvinobudirira mumapurojekiti akakosha akadai semvura yemanisipala uye madhiraivha network, kureba gasi rechisikigo uye mafuta ekufambisa, uye pombi mirwi masisitimu, achipa akasimba uye anogara akasimba ekufambisa "midziyo yeropa" yekuvaka zvivakwa zvepasirese.
Kusarudza mugadziri ane zvitupa zvepasi rose idanho rekutanga rekuona kuvimbika kwenguva refu kwemapurojekiti epombi. Cangzhou Spiral Steel Pipe Boka, nekunyatso kuteedzera zviyero zveASTM uye yakasimba yakagadziridzwa kugadzirwa kwesimba, inopa vatengi mhinduro-yekumira kubva pakugadzira kusvika kune-kupokana.
Kuti uwane rumwe ruzivo nezve zvakatemwa, zvitupa zvetifiketi uye kugona kugadzirisa kweASTM yedu yakajairwa-inopindirana spiral simbi pombi, ndapota taura neboka redu rehunyanzvi kuti uwane ruzivo rwehunyanzvi hwekubvunza uye makotesheni.
