LSAW kav los ntawm Jinzheng yog tsim los ntawm cov ntaub ntawv muaj zog heev. Cov kav dej no yuav tsum tiv taus qhov hnyav thiab ib puag ncig hnyav. Lawv yog cov zoo tagnrho rau kev siv ntau yam, suav nrog cov haujlwm hauv kev lag luam roj thiab roj, kev tsim kho, thiab kev kho tsheb thiab cov choj. Lawv cov kav ntev qhia tau hais tias lawv tuaj yeem ua siab ntev nyob rau hauv qhov chaw uas lwm cov kav dej yuav muab kev pabcuam ob peb xyoos xwb.
Peb tsim cov kav dej Longitudinal Submerged Arc Vuam (LSAW) nrog cov txheej txheem tshwj xeeb. Cov yeeb nkab yog sib sau ua ke los ntawm vuam ob feem ntawm cov hlau thiab yog ruaj thiab muaj zog. Kauj Ruam 1: Peb muab ib daim hlau tiaj tus. Tom qab ntawd nws yog dov mus rau hauv lub cylindrical raj. Tom qab ntawd peb xa nws mus rau lub tshuab loj thiab cov npoo ntawm lub raj yog welded. Qhov vuam no ua rau cov yeeb nkab tsis sib haum, txhais tau tias nws tsis muaj cov ntsiab lus tsis muaj zog. Yog li ntawd, muaj cov yeeb nkab uas muaj zog heev uas tiv taus kev puas tsuaj ntau dua li lwm cov khoom siv yeeb nkab.
Cov kav dej zoo nkauj no tau siv rau hauv ntau qhov chaw thiab ntau qhov chaw. Piv txwv li, ncaj nraim yog siv los nqa cov roj thiab roj - cov peev txheej tau pom tob hauv av - los ntawm ib qho chaw mus rau lwm qhov, los ntawm qhov chaw uas nws tau ua kua thiab ua rau roj. Lawv kuj tau siv rau ntawm qhov chaw tsim kho, xws li tsim cov choj loj thiab qhov tunnels. Qhov ntawd txhais tau hais tias cov kav dej LSAW ua lub luag haujlwm tseem ceeb hauv ntau hom kev ua haujlwm uas tso cai rau peb cov zej zog kom vam meej thiab txuas nrog. "
Piv nrog rau lwm hom welded kav xws li ERW (Electric Resistance Vuam) thiab SSAW (Spiral Submerged Arc Vuam), LSAW kav muaj zog dua thiab toughness. Lawv kuj tuaj yeem tiv taus xeb thiab corrosion zoo dua li lwm cov kav dej. LSAW cov kav dej yog, yog li ntawd, ib qho kev xaiv zoo rau kev siv nyob rau hauv tej yaam num nyob rau hauv hnyav ib puag ncig xws li nyob rau hauv cov chaw uas muaj ntau ntawm noo noo los yog huab cua los ntawm cov tshuaj.
Peb kho qhov zoo heev ntawm Jinzheng. Peb cov LSAW Pipes yog tsim los ua kom tau raws li cov qauv nruj. Los ntawm lub zog vuam cov pob qij txha mus rau qhov kawg kov, peb xyuas kom meej tias cov pob qij txha muaj zog txaus ua haujlwm yam tsis muaj hiccups. Peb pom kev tshuaj xyuas cov kav dej, nrog rau kev ua haujlwm tshwj xeeb xws li kuaj ultrasonic thiab kuaj hydrostatic, kom paub tseeb tias cov kav dej yuav tuaj yeem tiv taus lub siab hnyav yam tsis muaj kev tawg lossis tawg. Cov kev ntsuam xyuas no muab kev lees paub tias cov kav dej uas peb tsim yuav ua tiav qhov kev cia siab zoo ntawm peb cov neeg siv khoom.
Shandong Changshengda Steel Co., Ltd. yog nyob rau hauv Tuam Tshoj tus lsaw yeeb nkab seamless steel yeeb nkab puag. Nws yog nruab nrog cov txheej txheem ntau lawm rhiav. Lub tuam txhab tau tsim nyob rau xyoo 2011 thiab yog "National 863 Program Implementation Unit".

lsaw yeeb nkab yog ib lub tuam txhab nrog ntau qhov chaw tsim khoom, suav nrog kub dov, txias dov, txias txheej txheej, galvanizing thiab tshuaj xyuas zoo. Nws tseem muaj ntawv pov thawj rau 90001 system rau kev tswj kom zoo. Nws cov khoom tsim txhua xyoo ntawm ntau tshaj li ib lab tons ntawm cov hlau tso cai rau nws khaws cov khoom zoo ntawm nws cov khoom thiab tseem khaws cov khoom muag ntawm 100000 tonnes ntawm tes txhua lub sijhawm ntawm lub xyoo. Nws yog ib tus khub txhim khu kev qha uas tuaj yeem yooj yim ua raws li cov neeg siv khoom xav tau sai rau kev xa khoom, kev tshuaj xyuas zoo, thiab lwm yam yuav tsum tau ua.
Shandong Changshengda Steel Co., Ltd muaj ntau tshaj 12 xyoo kev paub nyob rau hauv ntshuam thiab export Nws ua hauj lwm ib tug npaum mov saw system uas npog 150 lub teb chaws tso cai rau cov neeg muas zaub mus yuav khoom yam tsis tau tawm hauv tsev Thaum tib lub sij hawm muaj kev nkag siab tob txog cov nqi thiab kev lis kev cai. systems ntawm ntau yam lsaw yeeb nkab tuaj yeem pab cov neeg siv khoom los muab cov kev daws teeb meem zoo tshaj plaws uas tso cai rau lawv kom tau txais kev pabcuam zoo tshaj plaws rau tus nqi qis tshaj.
lsaw yeeb nkab tom qab-muag lav qhov system tseem yog lwm yam uas ua rau peb lub tuam txhab sawv tawm ntawm peb cov counterparts Peb lub tuam txhab tom qab muag yuav ua lub luag haujlwm rau txhua yam teeb meem uas tshwm sim xws li teeb meem nrog teeb meem kev thauj mus los tsis zoo lossis kev xa khoom qeeb hauv lub sijhawm them nyiaj pov hwm. Nyob rau theem kev lag luam nrog rau cov txheej txheem kev sib koom ua ke yav tom ntej peb yuav muab peb cov neeg siv khoom nrog cov nyiaj tshwj xeeb thiab muab cov kev xaiv zoo tshaj plaws thiab cov tswv yim kom tsis txhob muaj teeb meem hauv kev koom tes yav tom ntej kom peb cov neeg siv khoom tsis muaj kev txhawj xeeb thaum ua. kev yuav khoom
