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.
Kev ntsuam xyuas hydraulic hydraulic ntawm cov yeeb nkab galvanized yuav tsum tau ua nyob rau hauv lub raj dub, thiab qhov ntsuas vortex kuj tseem siv tau los ntawm kev ntsuas hydraulic. Kev ntsuas siab lossis ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov loj me yuav tsum ua raws li cov cai ntawm GB 3092.
Steel mechanics kev ua tau zoo yog qhov tseem ceeb ntawm kev ua kom ntseeg tau qhov kev ua tau zoo kawg (kev ua haujlwm zoo) ntawm cov hlau, uas nyob ntawm cov tshuaj muaj pes tsawg leeg thiab kev kho cua sov ntawm cov hlau. Nyob rau hauv cov txheej txheem steel yeeb nkab, raws li kev siv sib txawv, kev ua haujlwm ncab (lub zog tensile, yield zog lossis yield point, elongation point) thiab hardness, toughness indicators, thiab high thiab low temperature yuav tsum tau los ntawm cov neeg siv.
Kev ua cov galvanized steel yeeb nkab grooves
1. Siv lub tshuab txiav los txiav cov yeeb nkab steel ntawm qhov xav tau ntev, thiab qhov kev txiav yuav tsum tiaj tus.
2. Teem lub steel yeeb nkab khib uas yuav tsum tau ua tiav ntawm lub tshuab zawj.
3. Muab tus kav kab rov tav rau ntawm cov yeeb nkab steel thiab ua kom tus kav kab rov tav kom cov yeeb nkab steel horizontally.
4. Muab tshuaj txhuam qhov kawg ntawm cov yeeb nkab steel thiab cov menyuam kom nruj.
5. Pib lub tshuab zawj, thiab maj mam nias lub phaus kom lub log sab sauv sib npaug ntawm cov yeeb nkab steel kom txog thaum qhov chaw qhov zawj nres.
6. Txheeb xyuas qhov tob thiab qhov dav ntawm qhov zawj nrog lub cloak meter. Tom qab paub meej tias cov txheej txheem yuav tsum tau ua raws li tus qauv yuav tsum tau ua, tshem lub phaus mus rau lub nra thiab tshem tawm cov yeeb nkab steel.
