Hluav taws xob-Fusion-Welded Pipes ASTM A672

ASTM A672 Electrofusion Welded Yeeb Nkab Khoom Taw Qhia

ASTM A672 cov kav dej yog hluav taws xob -fusion-welded steel kav, tshwj xeeb yog tsim los rau siab - kev siv siab ntawm qhov kub nruab nrab. Lawv yog tsim los ntawm welding tus neeg hlau daim hlau thiab tom qab ntawd muab cov qauv welded rau kev sim nruj kom ntseeg tau tias kev ua haujlwm zoo tshaj plaws. Txoj kev tsim khoom no tso cai rau kev hloov kho ntawm cov yeeb nkab qhov ntev thiab cov khoom siv qib, ua rau nws tsim nyog rau ntau hom kev lag luam.

Cov yam ntxwv tseem ceeb thiab cov khoom ntawm ASTM A672 Pipes

Siab zog thiab kav ntev

Yield zog: Ntau yam ntawm 240 MPa (A55) txog 485 MPa (H80).

Tensile Strength: Ntau yam ntawm 415 MPa (A55) txog 620 MPa (H80).

Tsim los tiv thaiv kev kub ntxhov sab hauv, ua rau lawv zoo tagnrho rau kev xav tau ib puag ncig xws li cov chaw tsim hluav taws xob thiab cov chaw tsim khoom.

Txhim kho Corrosion Resistance

ASTM A672 cov kav dej feem ntau raug kho nrog cov txheej txheem tiv thaiv lossis tsim los ntawm kev siv corrosion-cov alloys resistant.

Haum rau ib puag ncig uas raug tshuaj lom neeg, noo noo, thiab kub hloov pauv.

Kub Tolerance

Muaj peev xwm ua haujlwm tau zoo ntawm qhov kub txog li 400 degree, ua rau lawv zoo tagnrho rau thermal fais fab nroj tsuag daim ntaub ntawv thiab chav pipelines.

Customizable Specifications

Outer Diameter (OD): Ntau yam ntawm 10 nti mus rau 80 nti.

Phab ntsa Thickness: Sch 10 txog Sch XXS, nyob ntawm seb yuav tsum tau ua daim ntawv thov.

Cov ntaub ntawv qib thiab phab ntsa thicknesses tuaj yeem tsim kho kom tau raws li cov kev xav tau tshwj xeeb.

Cov txheej txheem tsim khoom: Hluav taws xob{0}}Fusion Vuam (EFW)

Kev tshawb fawb tom qab ASTM A672 cov kav dej yog nyob rau hauv hluav taws xob - fusion vuam txheej txheem. Nov yog ib qho kev piav qhia:

Steel Phaj Xaiv: Siab- zoo steel phaj yog xaiv raws li qib thiab cov khoom uas yuav tsum tau muaj.

Ntug Kev Npaj: Cov npoo ntawm daim hlau yog ua tib zoo npaj kom zoo sib xws.

Fusion Vuam:

Cov phaj yog rhuab mus rau qhov xav tau kub uas siv hluav taws xob arc.

Raws li kev tswj xyuas, cov phiajcim yog fused ua ke los tsim cov yeeb nkab txuas ntxiv uas tsis muaj cov ntsiab lus tsis muaj zog.

Tshaj tawm -Weld Heat Treatment (PWHT):

Txhawm rau txhim kho cov khoom siv kho tshuab, cov kav dej tau txais kev kho cua sov.

Qhov no txo ​​cov kev ntxhov siab sab hauv thiab txhim kho kev tiv thaiv kom tawg thiab deformation.

Tsis yog -Kev Ntsuas Kev Puas Tsuaj (NDT):

Cov kav dej tau raug kuaj ultrasonic, kuaj radiographic, thiab ntsuas hydrostatic siab.

Cov kev ntsuam xyuas no xyuas kom meej tias cov welds ua tau raws li cov qauv nruj.

Hais txog peb lub tuam txhab

GNEE STEEL tau tsim muaj kev sib koom tes zoo nrog ntau lub tuam txhab ua lag luam thiab cov khoom lag luam hauv Suav teb, ua kom cov khoom ruaj khov thiab cov nqi sib tw. Nyob rau tib lub sijhawm, peb nkag siab tob txog kev lag luam thoob ntiaj teb kev xav tau thiab cov qauv sib txawv, muab cov lus qhia kev xaiv rau koj thiab cov ntaub ntawv kev lag luam.
