Raws li tus neeg muag khoom, Chengdu Shushengtai Steel Co., Ltd. muab siab - Galvanized Steel Pipes zoo thiab muaj kev taw qhia txog kev ua kom zoo dua cov txheej txheem vuam kom ntseeg tau cov qauv kev ntseeg siab thiab kev tiv thaiv corrosion. Cov txheej txheem vuam kom raug yog qhov tseem ceeb vim yog cov txheej txheem zinc, uas yuav tsum tau tuav tshwj xeeb piv rau cov qis qis - carbon steel.
Kev txiav txim siab tseem ceeb rau Vuam Galvanized Steel Pipes:
① Pre-Kev Npaj Vuam
Ua ntej vuam, cov txheej txheem kev npaj zoo ib yam li cov hlau tsis muaj - carbon steel, tab sis yuav tsum tau saib xyuas rau qhov ntev ntawm qhov zawj thiab qhov chaw galvanized nyob ib sab. Lub kaum ntse ntse yog 60-65 degree, nrog qhov sib txawv ntawm 1.5-2.5 hli. Txhawm rau tiv thaiv zinc paug hauv qhov vuam, nws raug nquahu kom tshem cov zinc txheej los ntawm qhov zawj ntawm qhov chaw ua ntej vuam.
② Vuam Method thiab Groove Control
Concentrated beveling thiab tsis muaj -blunt- ntug tswj pab ua kom zoo sib xws weld nkag. Ib ob - txheej txheej vuam txheej txheem yog qhov zoo dua los txo qhov kev pheej hmoo ntawm kev ua tsis tiav fusion thiab ua kom lub zog tsis sib xws thoob plaws lub vuam seam.
③ Kev xaiv electrode
Kev xaiv electrode nyob ntawm cov khoom siv hauv paus. Rau qis- cov kav dej carbon steel, feem ntau siv vuam rods muab kev ua haujlwm zoo thiab sib raug zoo nrog cov chaw galvanized.
④ Tswj Zinc Thaum Vuam
Thaum lub sij hawm ntau- hla vuam, nws yog ib qho tseem ceeb kom cia cov zinc txheej kom yaj thiab evaporate, txo nws cov tuav nyob rau hauv lub weld seam. Rau fillet vuam, txav cov electrode rau pem hauv ntej 5-7 hli raws li cov zinc melts, ces rov qab mus rau qhov chaw pib, pab tso vaporized zinc zoo, ua rau kom huv si, tsis xws luag - weld dawb.
⑤ Advanced Techniques for High -Quality Welds
Siv luv- arc vuam rods rau hla thiab ntsug vuam txo qis ntug hlawv. Tsis tas li ntawd, kev ua haujlwm rau pem hauv ntej-thiab- cov txheej txheem kev noj cov hlau rov qab ua kom muaj kev sib txuas zoo sib xws thiab txo qhov kev pheej hmoo ntawm qhov tsis xws luag.
Los ntawm kev ua raws li cov kev coj ua zoo tshaj plaws no, Chengdu Shushengtai Steel Co., Ltd. lav tias nws cov Galvanized Steel Pipes tuav ob qho tib si lub zog thiab lub sij hawm ntev - corrosion resistance, muab kev txhim khu kev qha rau kev tsim kho, kav dej, thiab kev lag luam.
