Njira Zowotcherera Mapaipi a Chitsulo a SSAW Pamizere ya Gasi

Kufotokozera Kwachidule:

Ponena za kukhazikitsa mapaipi a gasi, kuonetsetsa kuti dongosololi ndi lotetezeka komanso lodalirika ndikofunikira kwambiri. Mbali yofunika kwambiri pa ndondomekoyi ndi njira yolumikizira zinthu zomwe zimagwiritsidwa ntchito polumikiza zigawo zosiyanasiyana za mapaipi a gasi, makamaka pogwiritsa ntchito chitoliro chachitsulo cha SSAW. Mu blog iyi, tikambirana za kufunika kwa njira zoyenera zolumikizira zinthu pa mapaipi a gasi pogwiritsa ntchito chitoliro chachitsulo cha SSAW.

Chitoliro chachitsulo cha SSAW, yomwe imadziwikanso kuti chitoliro cholumikizidwa ndi arc, imagwiritsidwa ntchito kwambiri poyika mapaipi a gasi chifukwa cha kulimba kwake komanso mphamvu zake. Komabe, kugwira ntchito bwino kwa mapaipi amenewa kumadalira kwambiri mtundu wa njira zolumikizira zomwe zimagwiritsidwa ntchito poyika. Njira zolumikizira zosayenerera zimatha kubweretsa zolumikizira zofooka komanso zowonongeka, zomwe zimapangitsa kuti pakhale ngozi zachitetezo komanso kulephera kwa dongosolo.

Chimodzi mwazinthu zofunika kwambiri pakutsimikizira kuti kuyika kwa payipi ya gasi pogwiritsa ntchito chitoliro chachitsulo cholumikizidwa ndi spiral submerged arc ndiko kusankha njira yoyenera yolumikizira. Izi zikuphatikizapo kuganizira mosamala njira zolumikizira, zida zodzaza ndi kukonzekera kolumikizira. Kuphatikiza apo, kutsatira miyezo ndi malamulo amakampani ndikofunikira kwambiri kuti zitsimikizire kudalirika ndi chitetezo chamzere wa mafutasmachitidwe.

Kukonzekera bwino kulumikiza mapaipi achitsulo olumikizidwa ndi arc ndikofunikira kwambiri kuti mapaipi achitsulo olumikizidwa ndi arc omwe ali pansi pa madzi agwiritsidwe ntchito bwino. Izi zimaphatikizapo kuyeretsa bwino ndikuyang'ana pamwamba pa mapaipi kuti muchotse zodetsa zilizonse kapena zolakwika zomwe zingakhudze ubwino wa cholumikiziracho. Kuphatikiza apo, kuti chitolirocho chikhale cholimba komanso chodalirika, chitolirocho chiyenera kuyezedwa bwino ndikulinganizidwa bwino.

kapangidwe kozizira kopangidwa ndi welded

Pa nthawi yogwiritsira ntchito mapaipi enieni, kusamala kwambiri ndi kutsatira njira yoyenera n'kofunika kwambiri. Kusankha njira yoyenera yogwiritsira ntchito mapaipi, kaya ndi TIG (tungsten inert gas welding), MIG (metal inert gas welding) kapena SMAW (stick arc welding), kuyenera kusankhidwa kutengera zofunikira za kukhazikitsa mapaipi a gasi. Kuphatikiza apo, kugwiritsa ntchito zipangizo zodzaza zapamwamba komanso njira zogwiritsira ntchito mapaipi mosamala ndikofunikira kwambiri popanga ma weld odalirika komanso olimba omwe amakwaniritsa zofunikira pa ntchito za mapaipi a gasi.

Kuphatikiza apo, kuwunika ndi kuyesa pambuyo pa weld ndi njira zofunika kwambiri kuti zitsimikizire kuti weld ndi yabwino komanso yolondola pakuyika mapaipi a gasi pogwiritsa ntchito chitoliro chachitsulo cha SSAW. Njira zoyesera zosawononga, monga kuyesa kwa x-ray ndi kuyesa kwa ultrasound, zingathandize kuzindikira zolakwika zilizonse kapena kusagwirizana m'malo olumikizirana kuti athe kukonzedwa mwachangu ndikuwonetsetsa kuti makina anu opaira gasi ndi odalirika.

Mwachidule, njira zoyenera zowotcherera ndizofunikira kwambiri pakuyika mizere ya gasi pogwiritsa ntchito mapaipi achitsulo ozungulira omwe ali ndi arc welded. Kudalirika ndi chitetezo cha makina anu opachikira gasi kumadalira mtundu wa kuwotcherera kwanu, kotero miyezo yamakampani opachikira ndi njira zabwino ziyenera kutsatiridwa. Mwa kuyika patsogolo kukonzekera koyenera kowotcherera, njira zowotcherera mosamala, komanso kuwunika bwino pambuyo pa kuwotcherera, oyika mapaipi a gasi amatha kutsimikizira kudalirika ndi chitetezo cha kuyika mapaipi achitsulo a SSAW pakugwiritsa ntchito mapaipi a gasi.
