Q235B Spiral Tube
Zviyero zvinowanzo shandiswa zve spiral simbi pombi dzinowanzo kupatsanurwa kuita: SY/T5037-2000 (Ministry chiyero, inonziwo spiral seam yakanyura arc welded simbi pombi yemapaipi ekufambisa emvura akajairwa), GB/T9711.1-1997 (National standard, inonziwo oiri uye gasi indasitiri yekuparadzira simbi pombi Chikamu chekutanga chehunyanzvi hwekuunza mamiriro: Giredhi A simbi pombi (GB/T9711.2 Giredhi B simbi pombi inodiwa zvakanyanya), API-5L (American Petroleum Institute, inonziwo pipeline simbi pombi; iyo yakakamurwa kuita mamakisi maviri: PSL1 uye PSL2), SY/T5040-92 (Spiral akanyura arc welded simbi pombi nokuda murwi).
(1) Zvishandiso zvinogadzirwa simbi dzemachira, waya dzewelding, uye fluxes.Kuongororwa kwakasimba kwemuviri nemakemikari kunodiwa usati waisa mari.
(2) Butt joint ye strip simbi musoro nemuswe, uchishandisa imwe-waya kana mbiri-waya yakanyudzwa arc welding, mushure mekukoira mupombi yesimbi, otomatiki yakanyura arc welding inoshandiswa kugadzirisa welding.
(3) Asati agadzira, tambo inoyera, kuchekwa kwemupendero, kuronga kwemupendero, kucheneswa kwepamusoro uye kuendesa, uye kusati kwabhenda kurapwa.
(4) Iyo yemagetsi yekubata pressure gauge inoshandiswa kudzora kudzvanywa kwemasilinda pamativi ese emutakuri kuti ive nechokwadi chekufambiswa kwakanaka kwemutsetse.
(5) Gamuchira chekunze chekutonga kana chemukati chekudzora roll kugadzira.
(6) Weld gap control mudziyo unoshandiswa kuve nechokwadi chekuti weld gap inosangana nezvinodiwa zvekushongedza, uye iyo dhayamita yepombi, chiyero chemisalignment uye weld gap inodzorwa zvakanyanya.
(7) Ose ari maviri emukati welding uye ekunze welding anotora American Lincoln yemagetsi welding muchina kune imwechete-waya kana mbiri-waya yakanyudzwa arc welding, kuitira kuti uwane yakagadzika welding yakatarwa.
(8) Welds inoongororwa neinternet inoenderera ultrasonic otomatiki flaw chiridzwa, icho chinovimbisa 100% isiri-inoparadza yekuvhara yekuvhara spiral welds.
(9) Shandisa mhepo yekucheka plasma muchina kucheka pombi yesimbi kuita zvidimbu zvega.
(10) Mushure mekucheka mupombi dzesimbi imwe chete, mapaipi matatu ekutanga esimbi ega ega anofanirwa kuomesesa hurongwa hwekutanga kuona kuti nzira yekugadzira pombi inokodzera isati yaiswa zviri pamutemo mukugadzirwa.
(11) Zvikamu zvine inoenderera sonic flaw yekuona mamaki pane welds inoitiswa manual ultrasonic uye X-ray kuongorora zvakare.
(12) Mapombi anosonwa nesimbi yesimbi butt welding uye majoini akaita D-achipindirana nespiral welding seams ose anoongororwa neX-ray terevhizheni kana kutora firimu.
(13) Imwe neimwe pombi yesimbi inopinda muyedzo ye hydrostatic pressure, uye kudzvanywa kunotora chisimbiso cheradial.Iyo yekumanikidza yekuyedza uye nguva inodzorwa zvakanyanya nesimbi pombi hydraulic microcomputer yekuona mudziyo.Iwo bvunzo paramita anodhindwa otomatiki uye kurekodhwa.
(14) Pipe yekupedzisira machining, kuitira kuti verticality yekuguma kwechiso, bevel angle uye obtuse edge inogona kunyatsodzorwa.
Spiral seam undermerged arc welded steel pombi (SY5036-83) yekufambisa-inotakura mvura yekufambisa inonyanya kushandiswa pamapaipi ekutakura oiri negasi chaiwo;spiral seam yakakwirira-frequency welded simbi pombi (SY5038-83) yekumanikidza-inotakura mvura yekufambisa, uchishandisa high-frequency lap welding nzira Yakagadzirwa, spiral seam yakakwirira-frequency welded simbi pombi yekumanikidza-inotakura mvura yekufambisa.Iyo pombi yesimbi ine simba rakasimba-inotakura simba uye yakanaka plasticity, iyo yakanakira welding uye kugadzirisa.Kazhinji, spiral seam yakanyura arc welded simbi pombi (SY5037-83) yekufambisa-kudzvanywa kwemvura inogadzirwa nekaviri-mativi otomatiki yakanyudzwa arc welding kana imwe-sided welding yemvura, Yakanyura arc welded simbi pombi yekuendesa general low pressure fluid. zvakadai segesi, mhepo uye chiutsi
