    Khoom Ntawv

    Kawm txog A252 Qib 2 Hlau Hlau:

    A252 Qib 2 Steel Yeeb Nkabyog cov pa roj carbon cov yeeb nkab txheem tshwj xeeb tsim rau kev siv hauv cov ntawv thov siab piping thiab cov ntawv thov. Nws yog tsim raws li Astm (American Society rau kev sim thiab cov qauv), kom ntseeg tau cov qauv zoo thiab sab nrauv qhov tseeb. Cov qauv 2 qhia qhia tias cov yeeb nkab steel yog tsim los siv submerged arc vuam hlau vuam los yog seamless vuam kev.

    Qhov tseem ceeb ntawm ob tog submerged Arc Vuam:

    Ob chav submolled arc vuam, tseem hu ua DSAW, yog ib txoj kev siv vuam tshwj xeeb siv los koom nrog cov ntu ntawm A252 qib 2 qib 2. DSaw muaj ob peb qhov zoo dua lwm txoj kev vuam, suav nrog zoo heev Weld kev ncaj ncees, muaj kev tswj hwm zoo tshaj plaws, thiab kev tswj hwm zoo ntawm kev tawm tswv yim tshav sov. Nws ua kom muaj kev sib raug zoo ntawm cov kav dej ntawm cov kav dej, ua rau lawv tsis tshua muaj qoob loo, corrosion thiab cov qauv kev puas tsuaj.

    Vim li cas siv A252 qib 2 cov yeeb nkab steel rau cov lim dej?

    1. Lub zog zoo thiab durability: A252 Qib 2 muaj lub zog tensile muaj zog, ua rau nws tiv taus sab nraud ntxhov siab thiab kev ntsuas sab nraud. Lawv txoj kev tsis txaus ntseeg ua kom muaj kev pabcuam ntev dua, txo qhov kev xav tau hloov ntau zaus lossis kho vaj tse.

    2. Corrosion Kuj: A252 Qib 2 yog tsim los tiv thaiv hnyav, muaj kuab lom thiab noo noo, tsis muaj corrading lossis degrading lossis tsis ncaj ncees. Qhov no tshwj xeeb tau nce qhov kev pabcuam lub neej ntawm cov kav dej lim dej.

    3. Nqi-Siv tau: A252 Qib 2 Steel Yeeb muab cov tshuaj zoo siv rau cov dej quav yeeb nkab. Lawv cov kev saib xyuas me me thiab lub neej ntev thiab yuav cawm tau cov neeg saib xyuas thiab cov phiaj xwm cov phiaj xwm tseem ceeb tshaj sijhawm.

    Yeeb Nkab Wrding Cov Txheej Txheem

    Daim Ntawv Thov ntawm A252 Qib 2 Cov Yeeb Nkab Hauv Dej Steel hauv Serer Engineering:

    A252 Qib 2 steel hlau yog dav siv nyob rau hauv ntau yam ntawm ntau yam ntawm ntau cov dej phwj dej, suav nrog:

    1. Kev siv dej pheebsuab: A252 Qib 2 tau siv dav hauv kev tsim kho cov dej hauv nroog thiab cov khoom lag luam los kho cov nroj tsuag.

    2. Muaj cov dej phwj dej hluav taws xob: kev lag luam complexes yuav tsum muaj cov lim dej khov kho kom haum rau cov chaw ua haujlwm thiab lwm cov chaw tsim khoom thiab lwm cov chaw tsim khoom.
