API 5L Spiral Welded Steel Pombi Ongororo:
Standard: API 5L
Tsananguro: API 5L inotsanangura zvinodiwa pakugadzirwa kwematanho maviri ekugadzirwa kwechigadzirwa (PSL1 nePSL2) emapombi esimbi asina musono uye akasungirirwa. Mapombi eSSAW (Spiral Submerged Arc Welded) imhando yepombi yesimbi yakasungirirwa inogadzirwa nenzira ye spiral welding, iyo inobvumira kugadzirwa kwemapombi ane dhayamita hombe.
Magadzirirwo eMapaipi eSimbi Akasungirirwa e1500MM SSAW:
Dhayamita:1500mm (60 inches)
Ukobvu hwemadziro:Ukobvu hwemadziro hunogona kusiyana zvichienderana nezvinodiwa, asi hunhu hwakajairika hunotangira pa6mm kusvika 25mm kana kupfuura.
Giredhi reSimbi:
PSL1: Magiredhi akafanana anosanganisira A, B, X42, X46, X52, X56, X60, X65, X70.
Maitiro Ekugadzira:
SSAW (Spiral Submerged Arc Welding): Maitiro aya anosanganisira kutenderedza simbi inopfurwa nemoto nguva dzose pa mandrel inotenderera pakona yakatarwa ku axis yepombi, zvichiita musono we spiral. Musono wacho unozobatanidzwa mukati nekunze uchishandisa welding ye submerged arc.
Kureba:Kazhinji inopihwa nehurefu hwemamita gumi nemaviri (mamita makumi mana), asi inogona kuchekwa zvichienderana nehukuru hwemutengi.
Kupfeka uye Kuisa Mucheka:
Kupfeka Kunze: Kunogona kusanganisira 3LPE, 3LPP, FBE, nedzimwe mhando kuti dzidzivirire ngura.
Mukati meLining: Inogona kusanganisira epoxy coating kuti isapararire ngura, simende mortar lining yemapaipi emvura, kana mamwe ma linings ane hunyanzvi.
Mhando dzemagumo:
Migumo Yakajeka: Yakakodzera kusungirirwa mumunda kana kubatana kwemuchina.
Migumo Yakachekwa: Yakagadzirirwa kusungirirwa.
Mashandisirwo:
Kutakura Oiri neGasi: Inoshandiswa zvakanyanya pakutakura oiri negasi rechisikigo.
Kutakurwa Kwemvura: Kwakakodzera mapurojekiti makuru ekupa mvura.
Zvinangwa zveMaumbirwo: Zvinogona zvakare kushandiswa mukushandiswa kwemaumbirwo anoda mapaipi akakura.
Simbi Yakasungirirwa yeSSAW. Kuvimbiswa Kwemhando:
Simba reGoho:Zvichienderana negiredhi, simba remukoho rinogona kubva pa245 MPa (yeGiredhi B) kusvika pa555 MPa (yeGiredhi X80).
Simba reKusimba:Zvichienderana negiredhi, simba rekudhonza rinogona kubva pa415 MPa (yeGiredhi B) kusvika pa760 MPa (yeGiredhi X80).
Kuedzwa kweHydrostatic:Pombi yega yega inoongororwa ne hydrostatic test kuti ive nechokwadi chekuti weld nemuviri wepombi zvakachengeteka.
Kuongorora Kwemativi:Inoita shuwa kuti pombi inosangana nehukuru hwakatarwa uye kushivirira.
