Njira Zowotcherera Zachitsulo za SSAW Zamizere ya Gasi
Chitoliro chachitsulo cha SSAW, yomwe imadziwikanso kuti submerged arc welded pipe, imagwiritsidwa ntchito poyika mapaipi a gasi chifukwa cha kulimba kwake komanso mphamvu zake.Komabe, mphamvu ya mapaipiwa imadalira kwambiri ubwino wa njira zowotcherera zomwe zimagwiritsidwa ntchito poika.Njira zowotcherera zosayenera zimatha kupangitsa mafupa ofooka komanso owonongeka, zomwe zimapangitsa kuti pakhale ngozi zachitetezo komanso kulephera kwadongosolo.

Chimodzi mwazinthu zofunika pakuwonetsetsa kukhulupirika kwa kuyika mapaipi a gasi pogwiritsa ntchito spiral submerged arc welded steel pipe ndi kusankha njira yoyenera kuwotcherera.Izi zikuphatikizapo kulingalira mozama za njira zowotcherera, zipangizo zodzaza ndi zokonzekera zowotcherera.Kuphatikiza apo, kutsata miyezo ndi malamulo amakampani ndikofunikira kuti muwonetsetse kudalirika ndi chitetezo chamzere wa gasismachitidwe.
Kukonzekera koyenera kowotcherera ndikofunikira kuti mutsimikizire kuwotcherera bwino kwa mapaipi achitsulo ozungulira ozungulira arc mumayendedwe oyika gasi.Izi zimaphatikizapo kuyeretsa bwino ndi kuyang'anitsitsa paipi kuti muchotse zonyansa kapena zolakwika zomwe zingakhudze ubwino wa weld.Kuonjezera apo, kuti mukwaniritse weld wamphamvu ndi wodalirika, chitolirocho chiyenera kuyeza bwino ndi kugwirizanitsa.
Pakuwotcherera kwenikweni, chidwi chatsatanetsatane komanso kutsatira njira yoyenera ndikofunikira.Kusankha njira yoyenera kuwotcherera, kaya TIG (tungsten inert mpweya kuwotcherera), MIG (zitsulo inert kuwotcherera mpweya) kapena SMAW (ndodo arc kuwotcherera), ayenera kusankhidwa potengera zofunika zenizeni za unsembe payipi mpweya.Kuphatikiza apo, kugwiritsa ntchito zida zamtundu wapamwamba kwambiri komanso njira zowotcherera mosamala ndizofunikira kuti pakhale ma welds odalirika komanso olimba omwe amakwaniritsa zofunikira zamapaipi amafuta.
Kuphatikiza apo, kuyang'anira ndi kuyezetsa pambuyo pa weld ndi njira zofunika kuonetsetsa kuti weld ndi kukhulupirika pakuyika mapaipi a gasi pogwiritsa ntchito chitoliro chachitsulo cha SSAW.Njira zoyesera zosawononga, monga kuyesa kwa radiographic ndi kuyesa kwa akupanga, zitha kuthandizira kuzindikira zolakwika zilizonse zomwe zingachitike kapena zosiyanitsidwa pamalumikizidwe owotcherera kuti athe kukonzedwa mwachangu ndikuwonetsetsa kudalirika kwa mapaipi anu a gasi.
Mwachidule, njira zowotcherera zolondola ndizofunikira pakuyika mizere ya gasi pogwiritsa ntchito mapaipi achitsulo ozungulira a arc welded steel.Umphumphu ndi chitetezo cha makina anu opangira gasi zimatengera mtundu wa kuwotcherera kwanu, chifukwa chake miyezo yamakampani owotcherera ndi njira zabwino ziyenera kutsatiridwa.Poika patsogolo kukonzekera koyenera, njira zowotcherera mosamalitsa, ndikuwunika mozama pambuyo pa kuwotcherera, oyika mapaipi a gasi amatha kutsimikizira kudalirika ndi chitetezo cha kuyika kwa chitoliro cha SSAW pakuyika mapaipi a gasi.
