API 5L Spiral Welded Steel Pipes mwachidule:
Muyezo: API 5L
Kufotokozera: API 5L imatchula zofunikira popanga milingo iwiri yotsimikizika yazinthu (PSL1 ndi PSL2) zamapaipi achitsulo opanda msoko komanso welded. SSAW (Spiral Submerged Arc Welded) mapaipi ndi mtundu wa welded zitsulo chitoliro opangidwa ndi ozungulira kuwotcherera njira, amene amalola kupanga mipope lalikulu awiri.
1500MM SSAW Mapaipi Azitsulo Zowotcherera Zofunikira:
Diameter:1500mm (60 mainchesi)
Makulidwe a Khoma:Makulidwe a khoma amatha kusiyanasiyana kutengera zomwe mukufuna, koma zikhalidwe zimayambira 6mm mpaka 25mm kapena kupitilira apo.
Gulu la Zitsulo:
PSL1: Magiredi wamba akuphatikizapo A, B, X42, X46, X52, X56, X60, X65, X70.
Njira Yopangira:
SSAW (Spiral Submerged Arc Welding): Njirayi imaphatikizapo kupindika kosalekeza kwa chitsulo chowotcha chowotcha pamiyala yozungulira pamakona odziwika kupita ku chitoliro, kupanga msoko wozungulira. Kenako msoko umawotcherera mkati ndi kunja pogwiritsa ntchito kuwotcherera arc pansi pamadzi.
Utali:Nthawi zambiri amaperekedwa kutalika kwa 12m (mamita 40), koma amatha kudulidwa kutalika kwamakasitomala.
Kupaka ndi Lining:
Kupaka Kwakunja: Kungaphatikizepo 3LPE, 3LPP, FBE, ndi mitundu ina yopereka chitetezo cha dzimbiri.
Lining Mkati: Itha kuphatikizira zokutira za epoxy zokana dzimbiri, matope a simenti amapaipi amadzi, kapena zomangira zina zapadera.
Mitundu Yomaliza:
Mapeto Opanda: Oyenera kuwotcherera kumunda kapena kulumikizana ndi makina.
Beveled Ends: Okonzekera kuwotcherera.
Mapulogalamu:
Kutumiza kwa Mafuta ndi Gasi: Amagwiritsidwa ntchito kwambiri potengera mafuta ndi gasi.
Kutumiza Madzi: Oyenera ntchito zazikulu zoperekera madzi.
Zolinga Zamapangidwe: Itha kugwiritsidwanso ntchito pamapangidwe omwe amafunikira mapaipi akulu akulu.
SSAW Welded Steel Pipes Quality Assurance:
Mphamvu Zokolola:Kutengera giredi, mphamvu zokolola zimatha kuyambira 245 MPa (kwa Gulu B) mpaka 555 MPa (kwa Gulu X80).
Kulimba kwamakokedwe:Kutengera giredi, kulimba kwamphamvu kumatha kuyambira 415 MPa (ya Gulu B) mpaka 760 MPa (ya Gulu X80).
Kuyeza kwa Hydrostatic:Chitoliro chilichonse chimayesedwa ndi mayeso a hydrostatic kuti atsimikizire kukhulupirika kwa weld ndi thupi la chitoliro.
Kuyang'ana Kwambiri:Imawonetsetsa kuti chitoliro chikukumana ndi miyeso ndi kulolerana kwake.
