LSAW (Submerged Arc Welded) cov kav dej, tseem hu ua ncaj seam submerged arc welded steel kav, yog qhov kev xaiv zoo tshaj plaws rau kev thauj mus los loj - txoj kab uas hla vim lawv cov txheej txheem tsim tshwj xeeb, kev ua haujlwm zoo heev, thiab kev hloov tau zoo dua. Lawv tau siv rau hauv cov ntawv thov xws li ntev - kev thauj mus los ntawm cov roj thiab roj, cov dej hauv nroog, thiab kev tsim vaj tsev hauv hiav txwv.
LSAW kav siv high- kub zoo- dov steel phaj ua raw cov ntaub ntawv, siv ncaj seam txoj kev thiab submerged arc vuam txheej txheem. Thaum lub sij hawm tsim khoom, cov khoom yog thawj zaug raug txiav siv lub tshuab CNC shearing, ua raws li ntau yam txheej txheem xws li ua ntej- dabtsi yog khoov, sib sau, vuam sab hauv, thiab vuam sab nraud. Piv nrog rau cov kav dej kauv welded, LSAW cov kav dej muaj cov seam ncaj, tsis txhob muaj kev ntxhov siab los ntawm lub kaum sab xis ntawm kauv welds. LSAW cov kav dej nthuav tawm cov qauv kev ruaj ntseg ntau dua nyob rau hauv cov xwm txheej huab cua xws li kev kub siab thiab kub qis. Lub submerged arc vuam txheej txheem zoo cais lub pas dej molten los ntawm huab cua los ntawm cov txheej txheem tiv thaiv flux, ua kom muaj kev sib txuas zoo nkauj, cov nplej zoo, thiab cov khoom siv vuam zoo sib xws nrog cov khoom siv hauv paus, txhim kho tag nrho cov load- cov kabmob muaj peev xwm ntawm cov kav dej.
Qhov tseem ceeb ntawm kev sib tw ntawm LSAW kav dej nyob rau hauv lawv lub zog siab thiab siab flux tsis kam. Peb cov khoom LSAW siv cov raj xa dej ntawm cov qib sib txawv, tso cai rau kev kho cov kav dej nrog cov phab ntsa sib txawv thiab cov kab uas hla kom tau raws li cov neeg siv khoom xav tau, npog ntau yam diameters.
Lawv ua tau raws li qhov yuav tsum tau ua ntawm siab - cov ntawv siv siab xws li ntev - cov kav dej thiab cov pa roj thiab cov kav dej siab - siab. Tsis tas li ntawd, los ntawm kev txhim kho vuam zoo thiab cov txheej txheem kho cua sov, cov kav xa dej tau nthuav tawm cov kev cuam tshuam zoo, tswj cov khoom siv kho tshuab zoo txawm tias nyob rau hauv qis - qhov kub thiab txias, ua rau lawv haum rau thaj tsam txias thiab qhov tob - dej hiav txwv.
LSAW pipelines ' superior corrosion kuj ua kom durability nyob rau hauv complex ib puag ncig. Peb cov LSAW pipelines muaj ntau yam kev tiv thaiv corrosion rau cov kev siv sib txawv: hauv kev thauj cov roj thiab roj, 3PE tiv thaiv- txheej txheej yog siv, siv cov qauv sib xyaw ntawm cov hmoov epoxy hauv qab, cov nplaum nruab nrab, thiab txheej txheej polyethylene kom ua tiav ntau txheej ntawm kev tiv thaiv corrosion, cuam tshuam, thiab kev laus; hauv cov dej hauv nroog thiab cov dej ntws tawm, cov txheej txheem tsis yog - tshuaj lom epoxy tiv thaiv kev ua qias tuaj tom qab; thiab hauv marine engineering, kev sib xyaw ua ke ntawm zinc txheej thiab tshuaj tiv thaiv - cov xim pleev xim zoo tiv thaiv qhov muaj zog corrosive los ntawm dej hiav txwv. Tsis tas li ntawd, sab hauv phab ntsa ntawm cov yeeb nkab tuaj yeem smoothed raws li qhov xav tau los txo cov kev thauj mus los, txo kev siv zog, thiab txhim kho kev thauj mus los.
LSAW kav dej muaj ntau yam kev siv thiab kev hloov kho tau yooj yim, ua rau lawv xaiv rau ntau qhov kev lag luam. Hauv kev lag luam hluav taws xob, LSAW cov kav dej yog qhov tseem ceeb ntawm qhov ntev - cov roj thiab cov kav dej nyob deb, ua kom muaj kev nyab xeeb ntawm kev thauj cov roj thiab cov roj los ntawm cov roj av mus rau cov chaw refineries ua tsaug rau lawv lub zog siab. Hauv kev tsim vaj tsev hauv nroog, loj- txoj kab uas hla LSAW cov kav dej yog siv hauv nroog loj dej thiab dej phwj kho, muab cov txiaj ntsig zoo hauv kev tiv thaiv corrosion thiab siab ntws. Hauv kev tsim kho dej hiav txwv, LSAW cov kav dej tuaj yeem siv rau kev thauj cov kav dej ntawm ntug dej hiav txwv roj thiab roj av thiab cov kav dej hauv qab hiav txwv, tiv thaiv dej hiav txwv yaig thiab kev nyuaj siab hauv hiav txwv. Hauv kev lag luam tshuaj, LSAW kav yog tsim rau thauj ntau yam kua qaub thiab alkali xov xwm thiab siab -kub kua, exhibiting zoo tshuaj stability. Peb cov kav dej LSAW tuaj yeem muab ntau yam kev sib txuas xws li kev sib txuas threaded, flange kev sib txuas, thiab kev sib txuas welded, nrog rau qhov ntev customized, phab ntsa thicknesses, thiab anti- kev kho corrosion daws kom tau raws li qhov xav tau ntawm kev lag luam sib txawv.
