Tus qauv lub npe ntawm kub-dip galvanized steel yeeb nkab khoom yog "tsawg-voltage kua thauj mus los ntawm kub-dip galvanized vuam steel yeeb nkab". Nws yog sab hauv thiab sab nraud kub-dip galvanized sab hauv thiab sab nraud kub galvanized raws li cov kav hlau welded, kom cov yeeb nkab sab hauv thiab sab nrauv ntawm cov yeeb nkab steel muaj zinc txheej, uas zoo heev txhim kho kev tiv thaiv corrosion ntawm cov hlau. cev. Tiag tiag li 20 npaug ntawm cov kav hlau zoo tib yam. Qhov kub-dip galvanized steel yeeb nkab yog siv los ua cov yeeb nkab conveying lossis hlau qauv. Nws yog dav siv nyob rau hauv hluav taws engineering, tsheb thauj mus los ntuj, roj av kev lag luam, dej conservancy engineering vaj tse, thiab vaj tse nyob. Cov khoom no yog hais txog kev siv US tus qauv ASTM A53, British bid BS1387, lub teb chaws tus qauv GB / T3091 thiab lub teb chaws tus qauv GB / T13793, thiab yuav tsum tsis txhob raug nyob rau hauv tsis-neutral ib puag ncig xws li acid, alkali, ntsev.
Pipeline technical requirements
(1) Qhov saum npoo ntawm lub raj - xaus rau qhov zawj ntu yog tiaj tus, tsis muaj pob tsis muaj qhov sib tw.
(2) Qhov nruab nrab ntawm qhov zawj yuav tsum yog concentric nrog lub raj phab ntsa, thiab qhov dav thiab qhov tob ntawm qhov zawj yuav tsum ua tau raws li qhov yuav tsum tau ua.
(3) Cov grooved grooves uas tau ua tiav los ntawm lub tshuab tank yuav tsum tsis txhob ua puas lub galvanized steel yeeb nkab.
