ASTM 430 Welded Steel Yeeb Nkab
Txhawm rau kom ntseeg tau tias kev ua haujlwm ntawm ASTM 430 Welded Steel Pipe thaum lub sijhawm tsim khoom, nws yog ib qho tseem ceeb uas yuav tsum tau tswj ntau yam txheej txheem tseem ceeb:
Tshuaj muaj pes tsawg leeg: Ua raws li cov txheej txheem tshuaj lom neeg tshwj xeeb, suav nrog chromium, carbon, silicon, thiab lwm yam, yog qhov tseem ceeb rau kev ua tiav cov khoom xav tau.
Vuam txheej txheem: Kev xaiv ntawm vuam txoj kev, xws li TIG, MIG, los yog submerged arc vuam, tuaj yeem cuam tshuam qhov zoo ntawm cov vuam. Kev siv cov vuam tsis zoo xws li tam sim no, qhov hluav taws xob, thiab kev mus ncig ceev yog qhov tseem ceeb.
Kev kho cua sov: Annealing tom qab vuam tuaj yeem pab, thiab txo cov kev ntxhov siab uas yuav ua rau muaj kev cuam tshuam lossis tawg.
Ua haujlwm txias: Yog tias cov yeeb nkab yuav ua haujlwm txias, theem ntawm deformation yuav tsum tau tswj kom ua tiav qhov xav tau lub zog thiab ductility yam tsis tau qhia txog kev ua haujlwm txias heev.
Kev tshuaj xyuas thiab kuaj: Kev tshuaj xyuas tsis tu ncua, suav nrog kev kuaj pom, hluav taws xob, ultrasonic, thiab etching, yog qhov tsim nyog los xyuas kom meej tias tsis muaj qhov tsis xws luag lossis tsis zoo hauv cov vuam lossis cov khoom siv.
Ua tiav: Qhov saum npoo ntawm cov yeeb nkab yuav tsum tsis muaj nplai, xeb, thiab lwm yam kab mob. Ib tug du, huv si yog ib qho tseem ceeb rau corrosion kuj thiab tsos.

FAQ:
Q1: Koj puas muab cov qauv? Puas yog dawb lossis ntxiv?
A1: Yog lawm, peb tuaj yeem muab cov qauv dawb thiab cov neeg siv khoom yuav them tus nqi thauj khoom.
Q2: Yuav ua li cas yog tias kuv tsis muaj kev paub txog kev xa tawm?
A2: Peb muaj tus neeg sawv cev txhim khu kev qha uas tuaj yeem xa khoom tuaj rau koj los ntawm hiav txwv / huab cua / Qhia rau koj lub qhov rooj. Txawm li cas los xij, peb yuav pab koj xaiv qhov kev pabcuam xa khoom zoo tshaj plaws.
Q3: Koj lub sijhawm ua haujlwm ntev npaum li cas?
A3: Yog tias nws nyob hauv Tshuag, nws feem ntau yog 5-10 hnub. Los yog, yog tias tsis muaj cov khoom muag, 15 hnub, nyob ntawm seb muaj pes tsawg.
