Weldolet, tseem hu ua pob tw welded ceg yeeb nkab sawv, yog hom ceg yeeb nkab sawv ntsug uas tau siv dav hauv xyoo tas los. Nws yog cov yeeb nkab txuas ntxiv siv rau kev sib txuas ntawm cov yeeb nkab, uas tuaj yeem hloov cov yeeb nkab txuas ib txwm muaj xws li txo cov tees, cov phaj txuas ntxiv, thiab cov yeeb nkab txuas ntxiv.
Qhov zoo
Weldolet muaj cov txiaj ntsig zoo xws li kev nyab xeeb thiab kev ntseeg tau, txo tus nqi, kev tsim kho yooj yim, txhim kho qhov nruab nrab ntws raws, kev tsim qauv, thiab tsim qauv yooj yim thiab xaiv. Lawv tau siv ntau zuj zus nyob rau hauv high-pressure, high-temperature, loj-inch, thiab tuab phab ntsa pipelines, hloov cov tsoos ceg yeeb nkab txuas txoj kev.
Weldolesyog hom yeeb nkab sib koom ua ke ntawm txhua qhov kav dej. Qhov no yog ib qho zoo tagnrho high-pressure yuag daim ntawv thov thiab welded rau lub qhov hluav taws xob ntawm cov yeeb nkab khiav. Qhov kawg yog inclined los pab txhawb cov txheej txheem no, yog li ntawd, qhov vuam yog suav tias yog lub pob tw welded haum.
Raws li cov ceg pob tw vuam txuas txuas ntxiv, cov weldolets ua raws li qhov hluav taws xob qhov hluav taws xob kom txo qis kev ntxhov siab. Nws muab kev txhawb nqa dav dav.
Feem ntau, nws qhov kev kawm tau zoo ib yam li lossis siab dua cov yeeb nkab qis dhau, thiab ntau yam khoom siv forging tau muab, xws li ASTM A105, A350, A182, thiab lwm yam.
Ntau lawm loj
Txoj kab uas hla ntawm cov yeeb nkab hauv qab yog 1/4 nti rau 36 ntiv tes, thiab txoj kab uas hla ntawm ceg yog 1/4 nti rau 2 nti. Tsis tas li ntawd, txoj kab uas hla loj tuaj yeem raug kho.
Lub cev tseem ceeb ntawm cov ceg yeeb nkab yog ua los ntawm cov khoom zoo tshaj plaws ua los ntawm cov khoom siv tib yam li cov raj xa dej, nrog rau cov pa roj carbon steel, alloy steel, stainless hlau, thiab lwm yam.
Ob leeg cov kav dej thiab cov kav dej tseem ceeb yog welded, thiab muaj ntau hom kev sib txuas ntawm cov kav dej los yog lwm cov kav dej (xws li cov kav dej luv, ntsaws, thiab lwm yam), cov twj paj nruag, thiab cov li qub, xws li pob tw vuam, qhov (socket) vuam, xov, thiab lwm yam. .

Yuav daws qhov teeb meem ntawm weldolet li cas
1. Tshawb xyuas cov qauv ntawm weldolet kom paub meej tias nws tsis zoo thiab tsis muaj qhov puas tsuaj.
2. Txheeb xyuas qhov vuam ntawm lub weldolet kom paub tseeb tias nws muaj kev ruaj ntseg thiab tsis muaj qhov xau.
3. Tshawb xyuas qhov kev txhawb nqa ntawm lub weldolet kom paub tseeb tias nws muaj kev ruaj ntseg thiab tsis muaj cov dej xau.
4. Txheeb xyuas qhov kev teeb tsa ntawm lub weldolet kom paub tseeb tias nws muaj kev ruaj ntseg thiab tsis muaj qhov xau.
Tsis tas li ntawd, ua ntej txhim kho lub weldolet, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo tshuaj xyuas nws cov qauv, vuam qhov chaw, kev txhawb nqa qhov chaw, thiab qhov chaw teeb tsa kom ntseeg tau tias lawv txhua tus muaj kev nyab xeeb thiab tsis muaj qhov xau.
