High Quality Txheej Steel Yeeb Nkab
High Quality Txheej Steel Yeeb Nkab
(1) Cov txheej txheem tsim khoom ntawm seamless steel yeeb nkab tuaj yeem muab faib ua ntau pawg: kub dov (extrusion), txias dov (kos duab) thiab kub nthuav dav hlau yeeb nkab.
(2) Raws li cov txheej txheem tsim, welded yeeb nkab tuaj yeem muab faib ua ncaj seam welded steel yeeb nkab, kauv welded steel yeeb nkab, phaj coil taub qab welded steel yeeb nkab thiab welded yeeb nkab thermal expansion steel yeeb nkab.
Raws li cov duab, steel kav yuav muab faib ua: round yeeb nkab, square yeeb nkab, rectangular yeeb, octagonal, hexagonal, D-puab, pentagonal thiab lwm yam tshwj xeeb-shaped steel kav, complex seem steel kav, ob chav concave steel kav, tsib nplooj ntoos. quincunx steel kav, conical steel kav, corrugated steel kav, melon noob steel kav, ob chav convex steel kav, thiab lwm yam.
Cov yeeb nkab steel tuaj yeem muab faib ua: steel yeeb nkab rau cov kav dej, cov yeeb nkab steel rau cov khoom siv thermal, steel yeeb nkab rau kev lag luam, steel yeeb nkab rau roj av thiab geological drilling, thawv steel yeeb nkab, steel yeeb nkab rau tshuaj lom neeg kev lag luam, steel yeeb nkab rau lub hom phiaj tshwj xeeb, thiab lwm yam. Anti-corrosion faib ntawm sab hauv phab ntsa: folding kua epoxy txheej ipn8710 los tiv thaiv corrosion thiab folding fusion bonded epoxy hmoov los tiv thaiv corrosion.
Kev faib tawm ntawm sab nrauv phab ntsa tiv thaiv corrosion: folding 2PE / 3PE anti-corrosion, ib txheej PE tiv thaiv corrosion thiab folding epoxy thee asphalt anti-corrosion.Cov txheej txheem tiv thaiv corrosion: FBE epoxy hmoov los tiv thaiv corrosion yuav tsum ua raws li SY / t0315-2005 technical specification rau ib txheej fusion bonded epoxy hmoov txheej txheej ntawm steel pipeline, 2PE / 3PE anti-corrosion yuav tsum ua raws li GB / t23257-2009 technical standard rau polyethylene txheej txheej ntawm faus steel kav, tiv thaiv corrosion nto xeb tshem tawm tus qauv: xuab zeb blasting rau sab nrauv ntawm cov yeeb nkab steel yuav tsum ncav cuag SA2 1/2 raws li qhov yuav tsum tau ntawm GB / t8923-2008, thiab qhov tob ntawm thauj tog rau nkoj lis ntawm nto ntawm cov yeeb nkab steel yuav tsum yog 40-100 μ m.
Lub hauv paus cov ntaub ntawv ntawm cov kav dej los tiv thaiv corrosion muaj xws li cov kav dej kav, cov kav dej ncaj nraim, cov kav dej seamless, thiab lwm yam hauv Suav teb, lawv tau siv dav hauv cov kav dej engineering xws li kev xa dej mus ntev, roj av, tshuaj lom neeg kev lag luam, roj av, cua sov. , kev kho dej phwj tuaj, dej qhov chaw, choj, steel qauv, kev xa dej hauv hiav txwv thiab piling.
Ntxiv nrog rau kev txhim kho lub neej kev pab cuam ntawm cov yeeb nkab steel los ntawm kev tiv thaiv corrosion, nws kuj tseem cuam tshuam rau hauv qab no:
1. Ua ke cov neeg kho tshuab lub zog ntawm cov yeeb nkab steel nrog corrosion kuj ntawm yas;
2. Cov txheej txheej phab ntsa yog ntau tshaj 2.5mm, tiv taus khawb thiab kev sib tsoo;
3. Kev sib txhuam coefficient ntawm sab hauv phab ntsa yog me me, 0.0081-0.091, txo kev siv zog;
4. Sab hauv phab ntsa ua tau raws li cov qauv kev noj qab haus huv hauv tebchaws;
5. Sab hauv phab ntsa yog du thiab tsis yooj yim rau nplai, nrog rau kev tu tus kheej.
