Kev lag luam Standard For Welded Pipe Manufacturing

Kev lag luam tus qauv rau welded yeeb nkab raug
Lub teb chaws thiab cov qauv kev lag luam ua raws li kev tsim cov weld feem ntau suav nrog cov hauv qab no:

Ib, national standard
1. Weld zoo li tus qauv:

① 《 vuam zoo li qib qhia: qhia txog kev faib tawm thiab cov kev xav tau ntawm vuam zoo li qib zoo, suav nrog geometric tsis xws luag ntawm qhov chaw vuam, qhov chaw tsis tsim nyog ntawm qhov chaw, nto burrs thiab txaws.

GB/T 7999-2014 《 Kev Ntsuas Tus Qauv rau Kev Pom Zoo ntawm Welded Cov Qauv Cov Tswv Cuab Qhia : Nws yog feem ntau siv tau rau cov tswv cuab ntawm cov khoom siv hlau ua los ntawm cov khoom siv hlau, thiab qhia cov qauv kev ntsuas rau qhov zoo li qub, suav nrog cov duab vuam, nto zoo, burr thiab tawv nqaij tsis xws luag.
2. Weld loj thiab daim ntawv thiab txoj hauj lwm kam rau ua tus qauv:
① 《Kev kam rau siab ntawm vuam qhov ntev nthuav qhia: qhia cov txheej txheem suav thiab cov tseev kom muaj ntawm vuam qhov ntev thiab geometric kam rau ua, suav nrog qhov siab qhov siab, vuam dav, vuam qhov sib nrug thiab sib koom ua ke.
②GB/T 1804-2000 《Limited Deviation of Steel for Mechanical Engineering express : Nws yog tsuas yog siv tau rau welded structural cov tswv cuab ua los ntawm cov ntaub ntawv hlau, thiab qhia cov qauv ntsuas ntawm lawv qhov ntev thiab cov duab thiab txoj hauj lwm tolerances, nrog rau welded pob qij txha, welded Cheebtsam thiab cov khoom sib dhos.
3.Technical qauv rau vuam cov ntaub ntawv:
①GB/T 14957-2017 《Technical Conditions for Welding Materials express: specifications the technical conditions for welding material of metallic materials and nonmetallic materials, including covered electrode, welding wire, welding hmoov thiab shielding gas.
4. Weld zoo thiab soj ntsuam tus qauv:
①Weld cov qauv zoo feem ntau xav kom cov npoo npoo yuav tsum du, tsis muaj cua qhov, nrog me ntsis txaws, thiab weld ceg loj yuav tsum tau raws li qhov yuav tsum tau ua.
② Weld thib ob yuav tsum tsis txhob muaj teeb meem tsis xws luag pom ntawm qhov muag liab qab.
③ Yuav tsum tsis muaj qhov tsis xws luag xws li cov kab nrib pleb, cua qhov thiab slag suav nrog hauv qhov chaw vuam. Yog tias muaj qhov tsis xws luag, lawv yuav tsum tau kho raws li cov txheej txheem sib xws.
 

2, Cov qauv kev lag luam lossis cov qauv tshwj xeeb
Rau qee qhov kev lag luam tshwj xeeb lossis kev lag luam, xws li kev lag luam petrochemical, aerospace thiab lwm yam, tej zaum yuav muaj cov qauv nruj dua thiab cov kev cai rau kev tsim vuam. Cov qauv no yuav suav nrog ntau cov kev cai tshwj xeeb ntawm kev faib cov khoom siv vuam zoo, kev kuaj tsis zoo, kev xaiv cov khoom siv thiab lwm yam.
Txhawm rau ua tiav, kev tsim cov vuam seam yuav tsum ua raws li lub teb chaws thiab cov qauv kev lag luam kom ntseeg tau tias qhov zoo thiab kev nyab xeeb ntawm vuam seam. Hauv kev ua haujlwm tiag tiag, cov qauv tsim nyog thiab cov lus qhia tshwj xeeb yuav tsum raug xaiv raws li cov kev xav tau ntawm cov haujlwm tshwj xeeb lossis cov khoom lag luam, thiab kev tsim khoom thiab kev sim yuav tsum tau ua raws li cov kev cai nruj.
Peb tsis yog tsuas yog cov neeg tsim khoom, tab sis kuj yog cov neeg saib xyuas zoo. Txhua kauj ruam ntawm kev soj ntsuam zoo yog peb txoj kev cog lus rau cov neeg siv khoom. Raws li ib tug zoo benchmark nyob rau hauv kev lag luam, peb ib txwm ua raws li nruj kev soj ntsuam zoo. Peb tos ntsoov yuav ua haujlwm nrog koj los tsim Excellence ua ke.
