Yog1239 Txheem steel kav

Puas yog 1239 yog cov txuj ci tshwj xeeb rau cov kav hlau steel los ntawm Bureau of Indian cov qauv hauv kev thauj mus los thiab cov phiaj xwm kev tsim kho kom zoo nkauj. Tus qauv no tau muab faib ua ntau seem.

Tus Qauv Lub Npe:

Puas yog 1239: Kev qhia tshwj xeeb rau cov leeg hlau me me, tubular thiab lwm yam wrought steel fittings

• Tseeb version:

Yog 1239 tau muab faib ua ntau seem (Tshooj 1 txog Tshooj 3). Qhov tseeb hloov kho dua tshiab yuav tsum raug rau cov nom kev tso tawm ntawm Bureau of Indian cov qauv (BIS).

1. Steel yeeb nkab hom:

• Ntu 1: Seamless \/ Welded Hlau Tubes (Hlaub Me Me)

• Ntu 2: Galvanized Steel Leeg

• Ntu 3: Welded Cov Hlau Steel rau Cov Qauv Txheej Txheem

2. Daim Ntawv Thov Teb:

• Dej twj tso dej, tso dej thiab roj Kev Hloov Pipelines;

• Lub Cev Muaj Zog Hluav Taws Xob Hluav Taws Xob

• Kev tsim kho cov qauv kev txhim kho cov cheebtsam (xws li scaffolding);

• Kev siv cov tshuab engineering xws li kev tsim kho tshuab thiab kev ua haujlwm tsheb hlau.
 

1. Cov ntaub ntawv thiab tsim cov txheej txheem tsim khoom

• Cov khoom siv: cov hlau roj carbon ntau (hlau me), cov ntsiab lus me me), cov ntsiab lus carbon tsawg dua los yog sib npaug. 25%, manganese cov ntsiab lus tsawg dua lossis sib npaug rau 1.5%;

• Txoj kev sib raug:

Seamless steel kav (kub-tiav los yog txias-kos);

Welded steel kav dej (Reactance vuam erw lossis submerged arc vuam pom).

2. Qhov loj me thiab thev taus

• Txheej txheem hla ntau: 6 hli rau 150 hli (nrog rau me ntsis sib txawv hauv ntau qhov chaw);

• Daim phab ntsa thickness kam rau: nyob ntawm seb hom yeeb nkab steel, kev ua siab ntev rau seamless kav yog ± 10%, thiab rau welded kav, nws yog ± 10%.

• ntev: feem ntau yog 5.8 meters lossis customized ntev.

3. Cov Khoom Siv Kho Tshuab

Tensile lub zog: ntau dua los yog sib npaug rau 330 mpa;

• Elongation: ntau dua los yog sib npaug rau 20% (ntsuas cua (gauge ntev 50 hli);

Cov tseev kom muaj rau Galvanized Txheej (Tshooj 2):

• Zinc coating loj dua los yog sib npaug rau 610 g \/ m² (nruab nrab tuab ntau dua lossis sib npaug rau 85 μm);

Qhov kev sib txuam ntawm cov txheej yuav tsum tau dhau lub tooj sulfate xeem.

4. Kuaj thiab tshuaj xyuas

• Yuav tsum tau kuaj xyuas cov khoom lag luam:

• Kev ntsuas kev hydraulic (ntsuas ntsuas yog 1.5 zaug tsim kev tsim kho);

Nplaum ntawm galvanized txheej (winding kuaj lossis kev sim sib tsoo);

Tshuaj lom neeg cov tshuaj ntsuam xyuas, ntsuas qhov ntev, kev tshuaj xyuas zoo.

1. Xaiv lub hauv paus:

• Xaiv cov galvanized lossis tsis-galvanized steel kav dej raws li cov khoom siv hluav taws xob (dej, roj, roj av);
Nyob rau hauv high-siab scenarios, phab ntsa tuab thiab compressive zog yuav tsum tau txiav txim siab (yog 1239 steel kav feem ntau siv nyob rau hauv qis-siab scenarios).

2. Txhim kho thiab txij nkawm:

Zam txhob siv cov kav hlau tsis-galvanized steel nyob rau hauv kev xeb ib puag ncig;
Thaum vuam, nws yuav tsum tau sau tseg tias cov galvanized txheej yuav tso kua roj lom.

3. Daim ntawv pov thawj yuav tsum muaj:

• Kev lag luam Indian yuav tsum muaj ntawv pov thawj bis (ISI Mark);
Thaum kev xa tawm, nws yuav tsum ua raws cov qauv ntawm lub hom phiaj teb chaws.
