Pakupanga mapaipi a gasi lachilengedwe, kusankha zinthu ndi njira zowotcherera ndizofunikira kwambiri kuti zitsimikizire chitetezo ndi magwiridwe antchito. Chitoliro chachitsulo cha SSAW (Spiral Submerged Arc Welded) ndi chimodzi mwa zipangizo zomwe zimagwiritsidwa ntchito kwambiri mumakampani awa. Mu positi iyi ya blog, tifufuza kufunika kwa njira zoyenera zowotcherera pakukhazikitsa mapaipi a gasi lachilengedwe pogwiritsa ntchito chitoliro chachitsulo cha SSAW ndikupereka chitsogozo choyambira chomvetsetsa gawo lofunika kwambiri la kumanga mapaipi.
Kodi chitoliro chachitsulo cha SSAW n'chiyani?
Chitoliro chachitsulo cha SSAWAmapangidwa ndi zitsulo zolukidwa mozungulira kuti apange chitoliro cholimba komanso cholimba cha mainchesi akuluakulu. Mtundu uwu wa chitoliro ndi wotchuka kwambiri m'mafakitale a gasi ndi mafuta chifukwa cha kukana kwake kupsinjika kwakukulu ndi dzimbiri. Njira yake yopangira imagwiritsa ntchito welding yonyowa pansi pa nthaka, yomwe imapanga welds zoyera komanso zolimba, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito kwambiri monga mapaipi a gasi wachilengedwe.
Kufunika kwa Njira Zoyenera Zowotcherera
Kuwotcherera ndi gawo lofunika kwambiri pakupanga mapaipi a gasi lachilengedwe, ndipo ubwino wa chowotcherera ungakhudze kwambiri umphumphu wonse wa mapaipi. Njira zoyenera zowotcherera ndizofunikira kuti zitsimikizire kuti zolumikizira mapaipi achitsulo a SSAW ndi zolimba komanso zotetezeka kutayikira. Nazi zinthu zofunika kuziganizira powotcherera mapaipi achitsulo a SSAW pamapaipi a gasi lachilengedwe:
1. Njira Yowotcherera: Kusankha njira yowotcherera kumakhudza ubwino wa chowotcherera. Kutengera ndi zofunikira za polojekitiyi, njira monga TIG (Tungsten Inert Gas) kapena MIG (Metal Inert Gas) zingagwiritsidwe ntchito. Njira iliyonse ili ndi ubwino ndi kuipa kwake, ndipo kusankha njira yoyenera ndikofunikira kuti pakhale mgwirizano wolimba.
2. Kukonzekera Zinthu: Musanagwiritse ntchito cholumikizira, pamwamba pa chitoliro chachitsulo cholumikizidwa ndi chozungulira chozungulira chiyenera kukonzedwa. Izi zikuphatikizapo kuyeretsa pamwamba ndikuchotsa zodetsa zilizonse zomwe zingafooketse cholumikizira, monga dzimbiri, mafuta kapena dothi. Kuphatikiza apo, chitolirocho chiyenera kulumikizidwa bwino kuti chitsimikizire kuti cholumikiziracho chili chofanana.
3. Magawo a kutchinjiriza: Zinthu monga liwiro la kutchinjiriza, magetsi ndi mphamvu ziyenera kulamulidwa mosamala panthawi yachitoliro chachitsulo chowotchereraMagawo awa amakhudza momwe kutentha kumalowera komanso kuchuluka kwa kuzizira, zomwe zimakhudzanso momwe makina amagwirira ntchito.
4. Kuyang'anira pambuyo pa weld: Pambuyo pa weld, kuwunika kokwanira kuyenera kuchitika kuti kuzindikire zolakwika zilizonse kapena maulalo ofooka mu weld. Njira zoyesera zosawononga monga kuyesa kwa ultrasound kapena kuyesa kwa x-ray zingagwiritsidwe ntchito kuti zitsimikizire kuti weld ndi yolimba.
Kudzipereka Kwathu pa Ubwino
Kampaniyi, yomwe ili ku Cangzhou, m'chigawo cha Hebei, yakhala ikutsogolera pamakampani opanga mapaipi achitsulo kuyambira mu 1993. Kampaniyi ili ndi malo okwana masikweya mita 350,000, ili ndi chuma chonse cha RMB 680 miliyoni, ndipo ili ndi akatswiri 680 odzipereka kupanga mapaipi achitsulo apamwamba kwambiri ozungulira. Chidziwitso chathu chochuluka komanso zida zapamwamba zimatithandiza kukwaniritsa zofunikira zamakampani opanga mapaipi a gasi.
