API 5L Spiral Welded Steel Pipes Overview:
Chiyero: API 5L
Tsanangudzo: API 5L inotsanangura zvinodikanwa pakugadzirwa kwematanho maviri echigadzirwa (PSL1 nePSL2) emapombi esimbi asina musono uye akasungwa. SSAW (Spiral Submerged Arc Welded) mapaipi imhando yepombi yesimbi yakashongedzwa inogadzirwa nespiral welding nzira, iyo inobvumira kugadzirwa kwemapaipi makuru edhayamita.
1500MM SSAW Welded Steel Pipes Key Specification:
Diameter:1500mm (60 inches)
Kukora Kwemadziro:Ukobvu hwemadziro hunogona kusiyana zvichienderana nezvinodiwa chaizvo, asi maitiro akajairika anobva pa6mm kusvika 25mm kana kupfuura.
Simbi Giredhi:
PSL1: Magiredhi akajairika anosanganisira A, B, X42, X46, X52, X56, X60, X65, X70.
Manufacturing process:
SSAW (Spiral Submerged Arc Welding): Kuita uku kunosanganisira kuenderera kutenderedzwa kwesimbi inopisa-yakakungurutswa pane inotenderera mandrel pakona yakatarwa kune pombi axis, ichigadzira spiral seam. Musono unozoiswa welding zvese nemukati nekunze vachishandisa undermerged arc welding.
Urefu:Inowanzo kupihwa mukureba kwe12m (40 tsoka), asi inogona kutemwa kune hurefu hwakanangana nemutengi.
Coating uye Lining:
External Coating: Inogona kusanganisira 3LPE, 3LPP, FBE, uye mamwe marudzi ekupa kudzivirirwa kwekuora.
Internal Lining: Inogona kusanganisira epoxy coating yekudzivirira ngura, simende yedhaka lining yemapombi emvura, kana mamwe machira ane hunyanzvi.
End Types:
Plain Ends: Inokodzera kukwirisa munda kana mechanical coupling.
Beveled Ends: Yakagadzirirwa welding.
Applications:
Kufambiswa kweOiri neGasi: Inoshandiswa zvakanyanya kutakura oiri uye gasi rechisikigo.
Kufambiswa Kwemvura: Inokodzera zvirongwa zvakakura zvekupa mvura.
Zvinangwa Zvinangwa: Inogona zvakare kushandiswa mune zvimiro zvekushandisa zvinoda mapaipi makuru edhayamita.
SSAW Welded Steel Pipes Quality Assurance:
Goho Simba:Zvichienderana negiredhi, simba regoho rinogona kubva pa245 MPa (yeGrade B) kusvika pa555 MPa (yeGrade X80).
Tensile Simba:Zvichienderana negiredhi, simba rekusimba rinogona kubva pa415 MPa (yeGrade B) kusvika pa760 MPa (yeGrade X80).
Hydrostatic Testing:Imwe neimwe pombi inoiswa kune hydrostatic bvunzo kuti ive nechokwadi chekutendeseka kweiyo weld uye muviri wepombi.
Dimensional Inspection:Inovimbisa kuti pombi inosangana nehukuru hwakatarwa uye kushivirira.
