Welded Steel Yeeb Nkab: Ib Daim Ntawv Qhia Kom Paub Txog Kev Sib Txuas Zoo Thiab Txhim Kho

Qhia:

Thoob plaws hauv kev lag luam, cov kav hlau steel tau siv dav rau lawv lub zog, durability, thiab versatility.Thaum koom nrog cov kav hlau, vuam yog txoj kev nyiam.Vuam tsim cov kev sib txuas muaj zog uas tuaj yeem tiv taus kev kub ntxhov, ua rau nws tseem ceeb hauv cov haujlwm xws li kev tsim kho, roj thiab roj, thiab kev tsim khoom.Hauv qhov blog no, peb yuav dhia mus rau qhov tseem ceeb ntawm cov yeeb nkab steel vuam thiab muab cov lus qhia dav dav kom ua kom muaj kev sib txuas zoo thiab txhim khu kev qha

Mechanical Property

Tshuaj muaj pes tsawg leeg

Hydrostatic Test

Txhua qhov ntev ntawm cov yeeb nkab yuav tsum raug kuaj los ntawm cov chaw tsim khoom mus rau lub siab hydrostatic uas yuav tsim nyob rau hauv cov yeeb nkab phab ntsa ib qho kev ntxhov siab tsis pub tsawg tshaj 60% ntawm qhov tsawg kawg nkaus yield zog ntawm chav tsev kub.Lub siab yuav tsum tau txiav txim los ntawm qhov sib npaug hauv qab no:
P = 2st/D

Permissible variations In Weights and Dimensions

Txhua qhov ntev ntawm cov yeeb nkab yuav tsum tau hnyav nyias thiab nws qhov hnyav yuav tsum tsis txhob sib txawv ntau dua 10% tshaj lossis 5.5% raws li nws qhov hnyav, suav nrog nws qhov ntev thiab nws qhov hnyav ntawm ib chav tsev ntev.
Sab nraud txoj kab uas hla yuav tsum tsis txhob sib txawv ntau tshaj ± 1% ntawm lub npe nominal sab nraud txoj kab uas hla.
Phab ntsa thickness ntawm txhua qhov chaw yuav tsum tsis pub ntau tshaj 12.5% ​​raws li cov phab ntsa thickness.

Ntev

Ib qho random ntev: 16 txog 25ft (4.88 txog 7.62m)
Ob chav random ntev: tshaj 25ft txog 35ft (7.62 txog 10.67m)
Uniform lengths: permissible variation ± 1in

Xaus

Cov yeeb nkab yuav tsum tau muab tso rau hauv qhov xaus, thiab cov burrs ntawm qhov kawg yuav raug tshem tawm.
Thaum cov yeeb nkab kawg tau teev tseg rau bevel xaus, lub kaum sab xis yuav tsum yog 30 txog 35 degree

1. Nkag siab cov kav hlau:

 Cov kav hlautuaj nyob rau hauv ntau qhov ntau thiab tsawg, cov duab thiab cov ntaub ntawv, txhua qhov tsim nyog rau cov ntawv thov tshwj xeeb.Lawv feem ntau yog ua los ntawm carbon steel, stainless hlau los yog hlau alloy.Cov pa roj carbon steel kav tau dav siv vim lawv qhov kev pheej yig thiab lub zog, thaum cov kav hlau stainless muaj kev tiv thaiv zoo heev.Nyob rau hauv ib puag ncig kub, alloy steel kav yog nyiam.Kev nkag siab txog qhov sib txawv ntawm cov yeeb nkab steel yuav pab txiav txim siab qhov kev xaiv vuam tsim nyog.

2. Xaiv cov txheej txheem vuam:

Muaj ntau yam txheej txheem vuam siv los koom nrog cov yeeb nkab steel, suav nrog arc vuam, TIG (tungsten inert gas) vuam, MIG (hlau inert gas) vuam, thiab submerged arc vuam.Kev xaiv ntawm cov txheej txheem vuam yog nyob ntawm yam xws li hom steel, txoj kab uas hla ntawm cov yeeb nkab, qhov chaw vuam thiab kev sib koom ua ke.Txhua txoj kev muaj nws qhov zoo thiab cov kev txwv, yog li xaiv cov txheej txheem tsim nyog tshaj plaws rau daim ntawv thov xav tau yog qhov tseem ceeb.

3. Npaj cov yeeb nkab steel:

Kev npaj cov yeeb nkab kom zoo ua ntej vuam yog qhov tseem ceeb rau kev ua tiav kev sib koom ua ke muaj zog thiab txhim khu kev qha.Nws suav nrog kev ntxuav cov yeeb nkab saum npoo kom tshem tawm cov xeb, nplai lossis cov kab mob.Qhov no tuaj yeem ua tiav los ntawm kev siv tshuab ntxhua khaub ncaws xws li hlau txhuam lossis sib tsoo, lossis siv cov tshuaj ntxuav tes.Tsis tas li ntawd, chamfering cov yeeb nkab kawg tsim V-shaped zawj uas tso cai rau kev nkag mus zoo dua ntawm cov khoom siv muab tub lim, yog li ua kom yooj yim rau txoj kev vuam.

4. Vuam tshuab:

Cov txheej txheem vuam siv tau cuam tshuam rau qhov zoo ntawm kev sib koom ua ke.Nyob ntawm cov txheej txheem vuam siv, qhov tsim nyog tsis xws li vuam tam sim no, qhov hluav taws xob, kev mus ncig ceev thiab cov khoom siv hluav taws xob yuav tsum tau khaws cia.Kev txawj ntse thiab kev paub ntawm tus welder tseem ua lub luag haujlwm tseem ceeb hauv kev ua tiav qhov zoo thiab tsis muaj qhov tsis xws luag.Cov txheej txheem xws li kev ua haujlwm electrode kom zoo, tuav lub arc ruaj khov, thiab ua kom muaj kev tiv thaiv cov roj txaus txaus tuaj yeem pab txo qis qhov tsis xws luag xws li porosity lossis tsis muaj fusion.

5. Kev tshuaj xyuas tom qab vuam:

Thaum lub vuam tiav lawm, nws yog ib qho tseem ceeb uas yuav tsum tau ua ib qho kev soj ntsuam tom qab vuam los xyuas seb muaj qhov tsis zoo lossis qhov tsis zoo uas tuaj yeem cuam tshuam qhov kev ncaj ncees ntawm kev sib koom ua ke.Cov kev sim uas tsis yog kev puas tsuaj xws li kev tshuaj xyuas qhov muag, kev tshuaj ntsuam xyuas qhov muag, kev kuaj sib nqus particle lossis kuaj ultrasonic tuaj yeem siv.Cov kev tshuaj xyuas no pab txheeb xyuas cov teeb meem uas yuav tshwm sim thiab xyuas kom cov pob qij txha welded ua tau raws li qhov yuav tsum tau ua.

Hauv kev xaus:

 Hlau Yeeb Nkab Rau Vuamyuav tsum tau ua tib zoo xav thiab ua kom raug kom muaj kev sib raug zoo thiab txhim khu kev qha.Los ntawm kev nkag siab txog kev sib txawv ntawm cov yeeb nkab steel, xaiv cov txheej txheem vuam tsim nyog, ua kom tiav cov yeeb nkab, siv cov txheej txheem vuam tsim nyog, thiab ua cov kev soj ntsuam tom qab vuam, koj tuaj yeem ua tiav cov welds muaj zog thiab zoo.Qhov no nyob rau hauv lem pab txhim kho kev nyab xeeb, kev cia siab thiab kev pab lub neej ntawm steel kav nyob rau hauv ntau yam kev siv uas lawv yog ib qho tseem ceeb Cheebtsam.
