Semugadziri anotungamira mundima iyi,Cangzhou Spiral Steel Pipe Group Co., Ltd.inotevedzera mitemo yepasi rose uye inonyanya kugadzira electrofusion arc weldedmapaipi esimbi emusono anotendereraichifukidza magiredhi mashanu. Rudzi urwu rweASTM pombi yesimbiYakagadzirirwa kutakurwa kwezvinwiwa, magasi kana utsi, zvichiita kuti ishande zvakanaka munzvimbo dzakasiyana-siyana dzine kumanikidzwa kwakanyanya uye dzakaoma.
Simba rekambani rinobva mukukwanisa kwayo kugadzira zvinhu zvakawanda. Tine mitsetse gumi nemitatu yekugadzira mapaipi esimbi anotenderera uye mitsetse mina yekugadzira inorwisa ngura uye inopisa, inokwanisa kugadzira mapaipi esimbi anotenderera ane dhayamita yekunze inotangira pa219 millimeters kusvika 3500 millimeters uye ukobvu hwemadziro hunosvika 25.4 millimeters.
Zvigadzirwa zvayo zvemhando ye "Wuzhou" hazvingoteveri chete mitemo yakawanda yepasi rose yakaita seAPI Spec 5L ne EN 10219, asiwo zvinozadzisa zvizere zvinodiwa nemitemo mikuru yakaita seASTM A139 neASTM A252.
Mapaipi aya esimbi ekuChina anotevedzera zvinodiwa neASTM ane mikana yakawanda yekushandiswa. Akashanda zvinobudirira mumapurojekiti akakosha akadai senzvimbo dzemvura dzemaguta nedzekudhonza mvura, kutakura gasi rechisikigo nemafuta kure, uye masisitimu emapombi, zvichipa "tsinga dzeropa" dzakasimba uye dzinogara kwenguva refu dzekuvaka zvivakwa zvepasi rose.
Kusarudza mugadziri ane zvitupa zvepasi rose ndiyo nhanho yekutanga yekuona kuti mapurojekiti emapaipi akavimbika kwenguva refu. Cangzhou Spiral Steel Pipe Group, nekutevedzera kwayo mitemo yeASTM uye kugona kwayo kugadzira zvinhu zvakagadzirwa, inopa vatengi mhinduro dzega kubva pakugadzira kusvika pakudzivirira ngura.
Kuti uwane rumwe ruzivo nezve zvirevo, ruzivo rwechitupa uye kugona kugadzirisa mapombi edu esimbi anotenderera anoenderana neASTM, ndapota taura nechikwata chedu chehunyanzvi kuti uwane mazano akadzama ehunyanzvi uye makotesheni.
