Qhov sib txawv ntawm A671 thiab A672 EFW Pipes

ASTM A671 thiab A672 yog ob qho tib si qauv rau steel tubing ua los ntawm lub siab lub nkoj-zoo daim hlau los ntawm hluav taws xob fusion vuam (EFW) cov tswv yim nrog ntxiv cov hlau muab tub lim.

Txawm hais tias lawv zoo sib xws hauv ntau yam, xws li cov kev xav tau vuam, kev kho cua sov, thiab qhov ntev ntev, lawv txawv ntawm lawv qhov kev thov, qib, chav kawm, qhov ntev, thiab cov ntawv thov tshwj xeeb.

Scope ntawm daim ntawv thov

ASTM A671 Cov Lus Qhia Tshwj XeebTug: Txheem Specification rau Hluav Taws Xob-Fusion-Welded Steel Yeeb Nkab rau Atmospheric thiab Kub Kub

ASTM A 672 Cov Lus Qhia Tshwj Xeeb: Txuj Specification rau Hluav Taws Xob-Fusion-Welded Steel Yeeb Nkab rau Kev Pabcuam Siab Siab ntawm Cov Kub Kub

Qhov Loj

ASTM A671 Cov Lus Qhia Tshwj Xeeb: DN≥ 400 mm [16 in] thiab WT ≥ 6 mm [1/4].

ASTM A 672 Cov Lus Qhia Tshwj Xeeb: DN≥400mm [16 nyob rau hauv] thiab WT≤75mm [3 nyob rau hauv].

Chav sib piv

Cov raj raug cais raws li hom kev kho cua sov uas lawv tau txais thaum lub sijhawm tsim khoom thiab seb lawv puas tau kuaj xyuas hluav taws xob thiab ntsuas siab.

astm a671 txawv ntawm a672: chav kawm

ASTM A671 muaj ntau pawg ntau dua li ASTM A672, xav txog A671 txoj hauv kev ntau dua rau kev faib cov ntaub ntawv rau brittleness thiab tsis ua hauj lwm hom uas tuaj yeem tshwm sim hauv qhov kub thiab txias.
Qhov no yog vim tus qauv A671 muab cov ncauj lus kom ntxaws ntawm cov khoom cua kub uas tsis tshua muaj tsim los xyuas kom meej tias cov yeeb nkab yuav ua tau zoo nyob rau hauv txias txias.Nyob rau hauv qhov sib piv, ASTM A672 tsom rau kev hloov mus rau qhov sib txawv ntawm qhov sib txawv thiab qhov kub thiab txias, uas suav nrog kev sib ntsib thiab tswj ntau hom kev ntxhov siab.

Qib sib piv

Muab faib raws li hom phaj siv los tsim cov raj steel.

Cov qib sib txawv sawv cev rau cov tshuaj sib txawv thiab cov khoom siv kho tshuab rau qhov sib txawv siab thiab qhov kub thiab txias.

astm a671 txawv ntawm a672: qib

Cov qib sib txawv tuaj yeem cuam tshuam tus nqi thiab kev ua haujlwm ntawm ib qhov project.
Kev siv qib siab dua ntawm cov yeeb nkab steel feem ntau txhais tau tias cov khoom siv ntau dua, tab sis kev xaiv cov khoom tsim nyog tuaj yeem txo tus nqi kho thiab txuas ntxiv kev pab cuam lub neej ntev.

Cov ntawv thov tshwj xeeb

Daim ntawv thov rau ASTM A671 Steel Tubing

Cov kev pabcuam Cryogenic: xws li liquefied natural gas (LNG) tuav thiab tsheb thauj mus los, yuav tsum tau cov raj uas muaj peev xwm tswj xyuas cov khoom zoo ntawm qhov kub thiab txias.

Lub nroog gas mov systems: Hauv cov tshuab no, cov kav dej yuav tsum tau ua haujlwm ntawm qhov kub ntawm lub caij ntuj no, yog li cov qib tshwj xeeb ntawm cov yeeb nkab steel yuav tsum tau ua kom muaj kev nyab xeeb thiab ua haujlwm zoo.

Cov chaw ua tshuaj: Hauv kev ua tshuaj lom neeg thiab cua txias, qee cov kua dej tau ua haujlwm ntawm qhov kub thiab txias, yuav tsum tau siv ASTM A671 yeeb nkab los tiv thaiv cov yeeb nkab rupture vim brittleness ntawm qhov kub thiab txias.

Offshore platforms thiab roj drilling chaw: Cov chaw no feem ntau nyob hauv cov dej txias, thiab kev siv cov yeeb nkab A671 ua kom muaj kev ntseeg siab thiab ruaj khov nyob rau hauv qhov chaw txias marine.

Daim ntawv thov rau ASTM A672 Steel Tubing

Cov nroj tsuag muaj zog: Tshwj xeeb tshaj yog nyob rau hauv boiler thiab chav tshuab, cov tshuab no yuav tsum tau cov kav dej uas tiv taus qhov kub thiab txias rau kev nyab xeeb ntawm chav thiab dej kub.

Refineries: Nyob rau hauv cov txheej txheem refining, cov kav dej yuav tsum tau ua kom muaj txiaj ntsig zoo ntawm cov roj av thiab cov khoom lag luam ntawm cov chaw ua haujlwm sib txawv, thiab cov kav dej no yuav tsum muaj peev xwm tiv taus qhov kub thiab txias ntawm cov txheej txheem.

High-Pressure Transmission Kab: High-pressure kis tau tus mob kab yog siv los thauj cov high-pressure kua los yog gases xws li natural gas thiab roj.

Industrial Pressure Systems: Hauv kev tsim khoom thiab lwm yam kev siv hauv kev lag luam, ntau lub tshuab siab xav tau kev txhim khu kev lag luam siab kom ntseeg tau tias muaj kev nyab xeeb thiab ua haujlwm zoo.

Los ntawm kev sib txawv ntawm cov khoom no thiab cov ntawv thov, nws pom tseeb tias thaum ASTM A671 thiab A672 cov qauv yeeb nkab sib tshooj hauv qee qhov kev ua haujlwm, lawv ua haujlwm sib txawv nyob ntawm qhov tshwj xeeb ib puag ncig thiab kev ua haujlwm.
