Spiral Welded Steel Pipes Specifications thiab Standards
Specifications:Sab nraud txoj kab uas hla 219mm txog 3000mm; Thickness sch40, sch80, sch160; Ntev 5.8m, 6m, 12m lossis customized
Qib:SSAW cov kav dej tuaj yeem tsim tau ntau qib, suav nrog API 5L cov lus qhia zoo li Qib B, X42, X52, X60, X65, X70, thiab X80.
Qauv:Feem ntau tsim raws li cov qauv xws li API 5L, ASTM A252, lossis lwm yam kev qhia tshwj xeeb nyob ntawm daim ntawv thov.
API 5L: Cov qauv no yog muab los ntawm American Petroleum Institute thiab qhia txog cov kev cai rau kev tsim khoom ntawm ob theem khoom specification (PSL 1 thiab PSL 2) ntawm seamless thiab welded steel kav rau siv nyob rau hauv pipeline tsheb thauj mus los systems nyob rau hauv cov roj av thiab natural gas industries .
ASTM A252: Cov qauv no yog muab los ntawm American Society for Testing and Materials thiab npog nominal phab ntsa cylindrical steel yeeb nkab pawg uas lub tog raj kheej steel ua raws li cov neeg nqa khoom mus tas li lossis ua lub plhaub los tsim cov pob zeb hauv qhov chaw.
SSAW Kauv Welded Hlau Yeeb Nkab Txheej
3-Layer Polyethylene (3LPE) Txheej:Cov txheej no muaj fusion-bonded epoxy txheej, txheej nplaum, thiab txheej polyethylene. Nws muab kev tiv thaiv corrosion zoo heev thiab feem ntau siv rau cov kav dej hauv qhov chaw hnyav.
Fusion-Bonded Epoxy (FBE) Txheej:FBE txheej muab cov tshuaj tiv thaiv zoo thiab tsim nyog rau ob qho tib si saum av thiab hauv av.
Galvanizing:Cov txheej txheem galvanizing suav nrog kev siv cov zinc txheej tiv thaiv rau cov yeeb nkab steel los muab kev tiv thaiv corrosion. Kauv weld steel yeeb nkab yog immersed nyob rau hauv ib da dej ntawm molten zinc, uas tsim ib tug metallurgical daim ntawv cog lus nrog cov hlau, tsim ib tug check thiab corrosion-resistant txheej. Kub-dip galvanizing yog tsim rau ob qho tib si sab hauv thiab sab nrauv daim ntaub ntawv thiab muab kev tiv thaiv zoo heev tiv thaiv xeb thiab corrosion.
Kauv Welded Carbon Steel Pipes Applications
Roj thiab Roj Tsheb thauj mus los:Siv dav rau kev thauj cov roj av, roj av, thiab lwm yam khoom siv roj av mus ntev.
Kev faib dej:Haum rau cov kav dej vim lawv cov kav ntev thiab tsis kam tiv thaiv corrosion.
Kev siv tus qauv:Ua hauj lwm hauv kev tsim kho rau kev txhawb nqa, xws li hauv choj, vaj tse, thiab lwm yam kev tsim kho vaj tse.
Kauv Welded Carbon Steel Pipes Kev Tshuaj Xyuas thiab Kev Tswj Xyuas Zoo
Dimensional soj ntsuam:Cov kav dej raug kuaj xyuas kom ua raws li txoj kab uas hla, phab ntsa thickness, thiab ntev specifications.
Mechanical Testing:Cov kav dej raug sim rau lub zog tensile, tawm los lub zog, elongation, thiab toughness kom ntseeg tau tias lawv ua tau raws li cov qauv xav tau.
Kev kuaj tsis raug:
Kev Ntsuas Ultrasonic (UT): Siv los txheeb xyuas qhov tsis xws luag hauv qhov vuam seam.
Kev Ntsuas Hydrostatic: Txhua cov yeeb nkab tau raug kuaj xyuas hydrostatic los xyuas kom meej tias nws tuaj yeem tswj cov kev khiav hauj lwm siab yam tsis muaj dej.
Spiral Welded Carbon Steel Pipes Ntim thiab xa khoom
Ntim Cov Lus Qhia: nyob rau hauv hexagonal seaworthy bundles packed los ntawm steel strips, Nrog ob nylon slings rau txhua bundles.
Kev Qhia Txog Tus Me Nyuam: Nyob ntawm QTY, feem ntau ib hlis.
