Q345 Spiral Welded Pipe
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
(1) Zvigadzirwa zvesimbi machira esimbi, waya dzewelding, uye fluxes.Kuongororwa kwakasimba kwemuviri nemakemikari kunodiwa usati waisa mari.
(2) Butt joint ye strip simbi musoro nemuswe, tora imwe waya kana kaviri waya yakanyudzwa arc welding, mushure mekukoira mupombi yesimbi, tora otomatiki yakanyura arc welding 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) Iyo welding seam gap control mudziyo unoshandiswa kuve nechokwadi chekuti welding seam gap inosangana nezvinodiwa zvewelding, uye dhayamita yepombi, huwandu hwekusarongeka uye musono welding gap zvese zvinodzorwa.
(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) Mawelded seams ese anoongororwa neinternet inoenderera mberi ultrasonic otomatiki flaw chiridzwa, icho chinovimbisa 100% isiri-inoparadza yekuvhara yekuvhara spiral welds.Kana paine chakakanganisika, chinongo vhundutsa nekupfapfaidza mucherechedzo, uye vashandi vekugadzira vanogona kugadzirisa maparamendi chero nguva zvichienderana neizvi kuti abvise chikanganiso nenguva.
(9) Air plasma yekucheka muchina unoshandiswa kucheka pombi yesimbi kuita zvidimbu zvega.
(10) Mushure mekucheka mumapombi esimbi imwe chete, batch yega yega yepombi dzesimbi dzinofanirwa kupinda muhurongwa hwekutanga hwekuongorora kuti utarise zvimisikidzo, chimiro chemakemikari, fusion mamiriro eiyo welds, kunaka kwepamusoro kwepombi dzesimbi uye kupfuura ongororo isingaparadze. kuve nechokwadi chekuti nzira yekugadzira pombi inokodzera.Mushure meizvozvo, inogona kuiswa zviri pamutemo mukugadzirwa.
(11) Zvikamu zvine inoenderera sonic flaw yekuona mamaki pane weld inoongororwazve nemanual ultrasonic uye X-ray.Kana pane kukanganisa, mushure mekugadzirisa, ichapfuura nekuongorora kusina kukuvadza zvakare kusvikira yasimbiswa kuti kukanganisa kwakabviswa.
(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 hydrostatic pressure test, uye kumanikidza kunotora radial chisimbiso.Iyo yekumanikidza yekuyedza uye nguva inodzorwa zvakanyanya nesimbi pombi hydraulic microcomputer yekuona mudziyo.Iwo bvunzo paramita anodhindwa otomatiki uye kurekodhwa.
(14) Iyo pombi inopera inogadziriswa nemichina, kuitira kuti verticality yekuguma kwechiso, bevel angle uye obtuse edge inogona kunyatsodzorwa.
Parizvino, zviyero zvinowanzo shandiswa zve spiral simbi mapaipi anowanzo kupatsanurwa kuita: SY/T5037-2000 (Ministry standard, inonziwo spiral seam undermerged arc welded simbi pombi yemapaipi ekufambisa emvura), GB/T9711.1-1997 (National chiyero, chinonziwo oiri uye gasi maindasitiri ekufambisa Chikamu chekutanga chehunyanzvi hwekuburitsa mamiriro emapombi esimbi: Giredhi A mapombi esimbi (akanyanya kuomesesa ari GB/T9711.2 Giredhi B simbi mapaipi), API-5L (American Petroleum Institute, iyo inonziwo pipeline simbi mapaipi akakamurwa kuva mhando mbiri: PSL1 uye PSL2 Grade), SY/T5040-92 (Spiral submerged arc welded simbi pombi kuti murwi)
Spiral chubhu zvinhu:Q235A, Q23b, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb.Q345 L245 L290 X42 X46 X70 X80
Spiral simbi mapaipi anonyanya kushandiswa muinjiniya yekugovera mvura, indasitiri yepetrochemical, indasitiri yemakemikari, indasitiri yemagetsi emagetsi, kudiridza kwekurima, uye kuvaka maguta.Ndechimwe chezvinhu makumi maviri zvakakosha zvakagadzirwa munyika yangu.
Inoshandiswa pakufambisa kwemvura: kugovera mvura, drainage.Inoshandiswa kutakura gasi: marasha gasi, chiutsi, liquefied petroleum gasi.Nezvinangwa zvemaumbirwo: sepombi dzekututira, semabhiriji;piers, migwagwa, zvivakwa zvekuvaka, nezvimwe.
