Product Overview
Loj txoj kab uas hla SSAW (Spiral Submerged Arc Welded) steel yeeb nkab yog tsim los ntawm kev sib txuas ua ke kub -rolled steel coils rau hauv lub plhaub helical cylindrical, ua raws li los ntawm sab hauv thiab sab nraud submerged arc vuam. Txoj kev sib txuas txuas ntxiv no tso cai rau kev tsim cov kav dej loj - txoj kab uas hla los ntawm tus qauv - dav coils nrog kev tswj qhov kev ntxhov siab thiab qhov sib npaug ntawm qhov raug nyob rau qhov ntev ntev.

FAQ
Q: Dab tsi yog qhov siab tshaj plaws phab ntsa thickness muaj rau cov kab loj SSAW kav?
A: Qhov siab tshaj plaws phab ntsa thickness mus txog 25.4 hli, nyob ntawm seb qhov kev xaiv sab nraud thiab cov kev txwv qib steel tswj los ntawm kev txwv.
Q: Koj puas tuaj yeem muab cov kav dej nrog 3PE corrosion txheej sab nraud?
A: Yog. Hauv - cov tsev txheej txheej siv 3-txheej polyethylene (3PE) thiab 3-txheej polypropylene (3PP) txheej raws li DIN 30670 thiab ISO 21809 tus qauv.
Q: Dab tsi yog qhov txawv ntawm SSAW thiab LSAW rau kev siv cov qauv?
A: SSAW siv lub helical weld seam tsim los ntawm coils, muab kev ua haujlwm siab thiab tus nqi zoo rau txoj kab uas hla mus txog 3220 hli. LSAW siv ib txoj kab ntev lossis ob txoj hlua ntev los ntawm cov hlau hnyav, feem ntau xaiv rau cov phab ntsa tuab thiab cov kab me me.
Q: Koj puas ua raws li thib peb -kev tshuaj ntsuam xyuas (TPI) ua ntej xa khoom?
A: Yog. Cov koom haum soj ntsuam ywj pheej xws li SGS, BV, Intertek, thiab TUV tau tso cai rau hauv pem teb tag nrho rau kev kuaj pom thiab cov yeeb nkab tso tawm kos npe -tawm.
Q: Dab tsi kam rau ua qauv siv rau cov yeeb nkab ntev thiab ncaj?
A: Ntev ntev ua raws li cov qauv zeb kev coj ua (+/- 50 mm rau qhov ntev ntev), thiab tag nrho qhov sib txawv ntawm qhov ncaj tsis tshaj 0.2% ntawm tag nrho cov yeeb nkab ntev.
Q: Dab tsi yog tus qauv yam tsawg kawg nkaus txiav txim kom muaj nuj nqis (MOQ) rau cov qib kev cai steel?
A: MOQ yog khi rau coil dov batches, feem ntau pib ntawm 50 metric tons ib qhov loj / qib ua ke, txawm tias qhov me me tuaj yeem ua tiav los ntawm cov sijhawm tam sim no.
