Ubwino wa Chitoliro cha Gasi Chomwe Chili ndi Arc Welded Gas Line Choviikidwa M'madzi Kawiri

Ubwino wa Chitoliro cha Gasi Chomwe Chili ndi Arc Welded Gas Line Chithunzi Chodziwika

Kufotokozera Kwachidule:

Takulandirani ku Cangzhou Spiral Steel Pipe Group Co., Ltd., kampani yodziwika bwino yopanga mapaipi achitsulo cha kaboni chopangidwa ndi spiral welded. Kampani yathu imadzitamandira kugwiritsa ntchito ukadaulo watsopano wopangidwa ndi spiral submided arc welding womwe umatsimikizira kupanga mapaipi apamwamba kwambiri opangidwa ndi spiral seam kuti agwiritsidwe ntchito m'njira zosiyanasiyana.

Mu dziko la mapaipi, pali njira zosiyanasiyana zomangira ndi zipangizo. Njira yotchuka yolumikizira mapaipi ndi kuwotcherera arc submerged arc (DSAW) yomwe imagwiritsidwa ntchito kwambiri pamizere ya gasi ndi madzi, ndipo pali chifukwa chomveka. Mu blog iyi tifufuza ubwino wogwiritsa ntchitocholumikizira cha arc choviikidwa m'madzi kawirichitoliro mu ntchito izi.

Mayeso a Hydrostatic

kufotokozera kwa malonda1

Chitolirocho chiyenera kupirira mayeso a hydrostatic popanda kutuluka kudzera mu msoko wa weld kapena thupi la chitolirocho.
Zolumikizira siziyenera kuyesedwa ndi madzi, bola ngati magawo a chitoliro chomwe chimagwiritsidwa ntchito polemba zolumikizira adayesedwa bwino ndi madzi asanayambe ntchito yolumikizira.

Kuwotcherera kwa Arc Yokhala ndi Helical Drived

Choyamba, kuwotcherera mapaipi awiri odzazidwa ndi madzi ndi njira yabwino komanso yotsika mtengo yolumikizira mapaipi. Njirayi imaphatikizapo kupanga cholumikizira polowetsa chitolirocho mu flux ya granular pogwiritsa ntchito ma arc awiri owotcherera. Izi zimapangitsa cholumikiziracho kukhala champhamvu komanso cholimba chomwe chingathe kupirira kupsinjika kwakukulu ndi kupsinjika, zomwe zimapangitsa kuti chikhale choyenera kugwiritsa ntchito mpweya ndi madzi.

Chimodzi mwa ubwino waukulu wa chitoliro cholumikizidwa ndi arc chomwe chimayikidwa m'madzi awiri ndi kukana dzimbiri. Kutuluka kwa granular komwe kumagwiritsidwa ntchito polumikiza izi kumapanga gawo loteteza pamwamba pa chitolirocho, zomwe zimathandiza kupewa dzimbiri ndikuwonjezera moyo wa chitolirocho. Izi ndizofunikira kwambiri kwamapaipi amadzi, chifukwa zimaonetsetsa kuti madzi operekedwa amakhala oyera komanso opanda kuipitsidwa.

Kuwonjezera pa kukana dzimbiri, mapaipi olumikizidwa ndi arc awiri okhala pansi pa nthaka amapereka mphamvu zabwino kwambiri zamakanika. Njirayi imapanga ma weld ofanana komanso chitoliro cholimba komanso chodalirika. Izi ndizofunikira kwambiri pamapaipi a gasi wachilengedwe chifukwa zimaonetsetsa kuti gasi wachilengedwe akuyenda bwino komanso motetezeka popanda kutayikira kapena kulephera kugwira ntchito.

Kuphatikiza apo, mapaipi olumikizidwa ndi arc awiri omwe ali pansi pa madzi amatha kupirira kutentha kwambiri komanso nyengo yoipa. Izi zimapangitsa kuti akhale abwino kwambiri pa ntchito za m'mphepete mwa nyanja komanso m'mphepete mwa nyanja zomwe zingachitike chifukwa cha nyengo yoipa komanso momwe zinthu zikuyendera. Pa mapaipi olumikizira madzi, kulimba kumeneku kumatsimikizira kuti mapaipi amatha kusuntha madzi bwino popanda kuwononga magwiridwe antchito.

Ubwino wina wogwiritsa ntchito chitoliro cholumikizidwa ndi arc wolumikizidwa kawiri ndi wakuti pamwamba pake ndi posalala komanso pokongola. Izi zimapangitsa kuti zikhale zosangalatsa kwambiri poyika pamwamba ndi pansi pa nthaka, chifukwa n'zosavuta kuziyang'ana ndikuzisamalira. Kuphatikiza apo, pamwamba pake polumikizidwa ndi weld amachepetsa kukangana ndi kutsika kwa mphamvu mkati mwa chitoliro, zomwe zimathandiza kukonza magwiridwe antchito a makina operekera mpweya ndi madzi.

Pomaliza, chitoliro cholumikizidwa ndi arc choviikidwa kawiri pansi pa madzi ndi chisankho chabwino kwambiri kwachitoliro cha mpweyandi mapaipi amadzi. Njira yake yowotcherera yogwira ntchito bwino komanso yotsika mtengo, pamodzi ndi kukana dzimbiri, makhalidwe abwino a makina, kulimba komanso kukongola, zimapangitsa kuti ikhale chisankho choyamba pakupanga mapaipi. Kaya amanyamula gasi wachilengedwe kapena madzi, mapaipi awa amapereka mphamvu ndi kudalirika kofunikira kuti agwire ntchito mosamala komanso moyenera. Mwachionekere, chitoliro chowotcherera cha arc chokhala ndi zigawo ziwiri ndi chinthu chamtengo wapatali padziko lonse lapansi pakupanga mapaipi.
