Online Exporter Tianjin Youfa Hom Kauv Welded Hlau Yeeb Nkab

Spiral Welded Steel Pipes Manufacturing Txheej txheem

Kev xaiv khoom siv:

Steel Coils: Cov hlau zoo hlau tau xaiv, feem ntau yog tsim los ntawm cov pa roj carbon tsawg lossis nruab nrab-carbon steel, kom ua tau raws li qhov yuav tsum tau muaj cov khoom siv thiab tshuaj lom neeg muaj pes tsawg leeg.

Uncoiling thiab Slitting:

Uncoiling: Cov hlau coils yog uncoiled thiab flattened rau hauv ib daim ntawv.
Slitting: Cov hlau flattened yog hlais rau hauv ib daim hlab ntawm qhov xav tau dav. Qhov dav ntawm lub sawb txiav txim siab txoj kab uas hla ntawm cov yeeb nkab kawg.

Kev tsim:

Kauv Tsim: Cov hlau sawb yog pub los ntawm cov txheej txheem ntawm cov chais uas maj mam tsim nws mus rau hauv cov duab kauv. Cov npoo ntawm cov sawb tau coj los ua ke hauv cov qauv helical los ua cov yeeb nkab.

Vuam:

Submerged Arc Welding (SAW): Kauv seam ntawm cov yeeb nkab yog welded siv cov txheej txheem submerged arc vuam. Qhov no suav nrog kev siv hluav taws xob arc thiab granular flux, uas muab lub zog zoo, zoo weld nrog me me spatter.
Weld Seam Inspection: Weld seam yog tshuaj xyuas kom zoo siv cov kev kuaj tsis muaj kev puas tsuaj xws li kev kuaj ultrasonic lossis radiographic.

Sizing thiab Shaping:

Sizing Mills: Cov yeeb nkab welded dhau los ntawm sizing mills kom ua tau raws li txoj kab uas hla thiab roundness yuav tsum tau.
Expansion: Hydraulic lossis mechanical expansion yuav siv tau los xyuas kom meej cov yeeb nkab ntev thiab txhim khu cov khoom siv.

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.

Ua tiav:

Beveling: Qhov kawg ntawm cov kav dej yog beveled los npaj rau vuam ntawm qhov chaw teeb tsa.
Kev kho deg: Cov kav dej yuav tau txais kev kho saum npoo xws li ntxuav, txheej, lossis galvanizing los txhim kho corrosion.

Kev tshuaj xyuas thiab kev tswj xyuas zoo:

Dimensional Inspection: 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, lub zog tawm los, elongation, thiab toughness kom ntseeg tau tias lawv ua tau raws li cov qauv xav tau.

Marking thiab ntim:

Kos npe: Cov yeeb nkab tau cim nrog cov ntaub ntawv tseem ceeb xws li cov chaw tsim khoom lub npe, cov yeeb nkab specifications, qib, qhov loj me, thiab cov xov tooj cua sov rau traceability.
Ntim: Cov kav dej yog bundled thiab ntim raws li cov neeg siv khoom xav tau, npaj rau kev thauj mus los thiab kev teeb tsa.
