Chidule cha Mapaipi a Zitsulo Opangidwa ndi API 5L Spiral Welded:
Muyezo: API 5L
Kufotokozera: API 5L imafotokoza zofunikira popanga mapaipi awiri achitsulo (PSL1 ndi PSL2) opanda msoko ndi olumikizidwa. Mapaipi a SSAW (Spiral Submerged Arc Welded) ndi mtundu wa mapaipi achitsulo olumikizidwa opangidwa ndi njira yolumikizirana, yomwe imalola kupanga mapaipi akuluakulu.
Makiyi Ofunika a Mapaipi a Chitsulo Opangidwa ndi SSAW a 1500MM:
M'mimba mwake:1500mm (mainchesi 60)
Kukhuthala kwa Khoma:Kukhuthala kwa khoma kumatha kusiyana malinga ndi zofunikira zake, koma mitengo yanthawi zonse imayambira pa 6mm mpaka 25mm kapena kuposerapo.
Kalasi yachitsulo:
PSL1: Magiredi ofanana ndi awa: A, B, X42, X46, X52, X56, X60, X65, X70.
Njira Yopangira:
SSAW (Spiral Submerged Arc Welding): Njirayi imaphatikizapo kupotoza kosalekeza kwa chingwe chachitsulo chozunguliridwa ndi moto pa mandrel yozungulira pa ngodya inayake ku axis ya chitoliro, ndikupanga msoko wozungulira. Kenako msokowo umalumikizidwa mkati ndi kunja pogwiritsa ntchito welding yozungulira.
Utali:Kawirikawiri imaperekedwa muutali wa mamita 12 (mapazi 40), koma imatha kudulidwa malinga ndi kutalika kwa kasitomala.
Kuphimba ndi Kuphimba:
Chophimba Chakunja: Chikhoza kuphatikizapo 3LPE, 3LPP, FBE, ndi mitundu ina kuti chiteteze dzimbiri.
Mkati: Zingaphatikizepo epoxy coating kuti isagwe ndi dzimbiri, simenti matope a mapaipi amadzi, kapena zina zapadera.
Mitundu Yotsiriza:
Mapeto Opanda Mtundu: Oyenera kuwotcherera m'munda kapena kulumikizana ndi makina.
Malekezero Opindika: Okonzeka kuwotcherera.
Mapulogalamu:
Kutumiza Mafuta ndi Gasi: Kumagwiritsidwa ntchito kwambiri ponyamula mafuta ndi gasi wachilengedwe.
Kutumiza Madzi: Koyenera mapulojekiti akuluakulu operekera madzi.
Zolinga za Kapangidwe ka Nyumba: Zingagwiritsidwenso ntchito pa ntchito za kapangidwe ka nyumba zomwe zimafuna mapaipi akuluakulu.
Chitsimikizo cha Ubwino wa Mapaipi a Chitsulo Osefedwa a SSAW:
Mphamvu Yopereka:Kutengera ndi giredi, mphamvu ya zokolola imatha kuyambira 245 MPa (ya Giredi B) mpaka 555 MPa (ya Giredi X80).
Kulimba kwamakokedwe:Kutengera ndi mtundu wa chipangizocho, mphamvu yokoka imatha kuyambira 415 MPa (ya Giredi B) mpaka 760 MPa (ya Giredi X80).
Kuyesa kwa Madzi:Chitoliro chilichonse chimayesedwa ndi hydrostatic kuti zitsimikizire kuti weld ndi thupi la chitoliro ndi zomangira zake ndi zolondola.
Kuyang'anira Magawo:Kuonetsetsa kuti chitolirocho chikukwaniritsa miyeso ndi kulekerera komwe kwatchulidwa.
