Hauv cov kav dej prefabricated, kev sib txuas ntawm cov kav dej thiab flanges yog qhov txuas tseem ceeb. ASME B16.5 flanges yog dav siv nyob rau hauv industrial piping systems raws li standardized accessories. Peb ntawm HT PIPE muabPre-Fabrication Pipe Spoolscov kev pabcuam, txuag lub sijhawm, ua kom zoo thiab txo cov nqi. Peb tuaj yeem ua kom ntseeg tau tias ASME B16.5 flange muaj kev ntseeg siab rau cov raj xa dej, tsim kom muaj kev sib txuas ruaj khov thiab zoo, thiab ua kom muaj kev ua haujlwm zoo ntawm cov kav dej ua ntej. Txawm nyob rau hauv cov roj av, tshuaj, los yog hluav taws xob industries.

Kev npaj
1. Kev tshuaj xyuas cov khoom:
Paub meej tias cov khoom ntawm flanges thiab cov kav dej ua tau raws li cov qauv tsim.
Tshawb xyuas flange thiab cov yeeb nkab qhov ntev kom ua raws li ASME B16.5 cov qauv.
2. Ntxuav:
Siv cov txhuam txhuam thiab cov kuab tshuaj los ntxuav cov welded qhov chaw ntawm flanges thiab cov kav dej kom tshem tawm cov roj, oxides thiab impurities kom huv si welding nto.
3. Txiav thiab polishing:
Yog hais tias cov yeeb nkab yuav tsum tau txiav, xyuas kom meej qhov chaw txiav yog tiaj tus thiab perpendicular mus rau axis ntawm cov yeeb nkab.
Polish qhov chaw txiav kom tshem tawm burrs thiab irregularities los xyuas kom meej qhov vuam nto du.
4. Kev sib tw:
Siv cov cuab yeej sib dhos kom ua tiav cov flange nrog cov yeeb nkab.
Xyuas kom meej tias lub flange nto yog perpendicular mus rau axis ntawm cov yeeb nkab kom tiv thaiv deflection.

Vuam txheej txheem
1. Spot vuam fixation:
Tom qab kev sib raug zoo, ob peb qhov chaw welds tau ua nyob rau ntawm qhov sib txuas ntawm cov yeeb nkab thiab flange kom ruaj ntseg txoj hauj lwm.
Tshawb xyuas qhov kev sib raug zoo kom paub tseeb tias tsis muaj qhov cuam tshuam loj ntawm lub flange thiab cov yeeb nkab.
2. Xaiv txoj kev vuam:
Xaiv txoj kev vuam tsim nyog raws li cov khoom siv ntawm cov yeeb nkab thiab flange, xws li TIG vuam, MIG vuam lossis phau ntawv arc vuam.
Xaiv qhov tsim nyog welding tsis, xws li tam sim no, voltage thiab vuam ceev, kom ntseeg tau tias vuam zoo.
3. Kev siv vuam:
Hauv paus welding yog ua ntej los xyuas kom meej qhov tob thiab lub zog ntawm lub vuam.
Raws li cov kev qhia tshwj xeeb ntawm vuam, sau welding thiab npog vuam yog ua los xyuas kom meej tias qhov chaw vuam yog du thiab zoo ib yam.
Tom qab txhua qhov vuam, siv cov cuab yeej ntxuav los ntxuav cov vuam kom tshem tawm cov vuam slag thiab oxides.
4. Weld soj ntsuam:
Siv cov kev sim uas tsis yog kev puas tsuaj xws li kuaj ultrasonic, kuaj X-ray lossis kuaj cov khoom sib nqus los kuaj xyuas qhov tsis xws luag hauv welds.
Ua ib qho kev soj ntsuam ntawm qhov pom ntawm qhov vuam kom paub meej tias nws tsis muaj kab nrib pleb, qhov hws, thiab lwm yam tsis xws luag.

Cov kev ceev faj
1. Kev tiv thaiv kev nyab xeeb:
Qhov kub thiab txias arc lub teeb thaum lub vuam yog tsim kev puas tsuaj rau tib neeg lub cev, thiab cov vuam yuav tsum hnav cov khoom tiv thaiv.
Qhov chaw ua haujlwm yuav tsum tau ua kom cua zoo kom tsis txhob muaj cov pa phem.
2. Preheating thiab postheating:
Rau siab carbon steel los yog hlau alloy, preheating ua ntej vuam thiab qeeb txias tom qab vuam yog tsim nyog los tiv thaiv cov kab nrib pleb nyob rau hauv lub vuam.
3. Kev ntxhov siab:
Cov kav dej loj lossis cov kav dej yuav xav tau kev kho kev ntxhov siab tom qab vuam los tiv thaiv kev deformation lossis tawg los ntawm kev ntxhov siab welding.
4. Kev tswj kom zoo:
Txhua kauj ruam ntawm kev ua haujlwm vuam yuav tsum tau ua raws li nruj raws li cov txheej txheem vuam txheej txheem kom ntseeg tau tias vuam zoo.
Tom qab welding tiav lawm, ib qho kev tshuaj xyuas zoo yog ua los xyuas kom meej qhov kev ntseeg tau ntawm cov pob qij txha welded.
