Iyo spiral simbi pombi inogadzirwa nekukungurutsa yakaderera-kabhoni structural simbi kana yakaderera-alloy structural simbi mutsetse mupombi, maererano neimwe kona ye spiral line (inonzi forming angle), uyezve welding pombi seams.
Inogona kushandiswa kugadzira hombe dhayamita simbi pombi ine nhete strip simbi.
Iyo dhizaini yespiral simbi pombi inoratidzwa nekunze dhayamita * madziro ukobvu.
Iyo welded pombi ichayedzwa neiyo hydrostatic bvunzo, kusimba kusimba uye kutonhora kukotama, kuita kweiyo welding seam kunosangana nezvinodiwa zvekutsanangurwa.
Chinangwa chikuru:
Iyo spiral simbi pombi inonyanya kushandiswa kufambisa mafuta uye gasi rechisikigo.
Nzira yekugadzira:
(1) Raw zvinhu: simbi coil, welding waya uye flux. Kuongororwa kwakasimba kwemuviri nemakemikari kuchaitwa kusati kwagadzirwa.
(2) The butt welding the head and muswe wecoil kuita kuti makoiri maviri abatanidzwe, obva atora waya imwechete kana mbiri waya dzakanyura arc welding, uye otomatiki yakanyura arc welding inotambirwa kuti isungirwe mushure mekukunguruka mupombi yesimbi.
(3) Asati agadzira, simbi yemutsetse ichagadziriswa, kuchekwa, kurongwa, kucheneswa, kutakurwa uye kumberi.
(4) Iyo yemagetsi yekubata pressure gauge inoshandiswa kudzora kudzvanywa kweinotsikirira silinda yemafuta pamativi ese emutakuri kuti ive nechokwadi chekufambisa kwesimbi simbi zvakanaka.
(5) Kugadzira roll, shandisa kutonga kwekunze kana kutonga kwemukati.
(6) Shandisa weld gap control kifaa kuti uve nechokwadi chekuti weld gap inosangana nezvinodiwa zvekushongedza, ipapo iyo pombi dhayamita, misalignment uye weld gap inogona kunyatsodzorwa.
(7) Ose ari maviri emukati welding uye ekunze welding anotora American Lincoln Magetsi welding muchina wewaya imwe chete kana waya mbiri dzakanyura arc welding, kuitira kuti uwane yakagadzikana welding performance.
(8) Yese welding seams inoongororwa ne-on-line inoenderera mberi ultrasonic otomatiki flaw detector kuona 100% NDT bvunzo inovhara ese spiral welding seams. Kana paine zvakakanganisika, zvinongo vhundutsa nekupfapfaidza mamaki, uye vashandi vekugadzira vanogadzirisa maparamendi chero nguva kuti vabvise hurema munguva.
(9) Iyo pombi yesimbi inochekwa kuita chidimbu chimwe chete nemuchina wekucheka.
(10) Mushure mekucheka mupombi imwe chete yesimbi, batch imwe neimwe yepombi yesimbi ichave iri pasi peyakasimba yekutanga yekuongorora system yekutarisa ma mechanika, chimiro chemakemikari, fusion mamiriro, pamusoro pemhando yepombi yesimbi uye NDT kuona kuti pombi yekugadzira pombi inokodzera isati yaiswa zviri pamutemo mukugadzirwa.
(11) Zvikamu zvine inoenderera mberi acoustic flaw yekuona mamaki pane welding seam ichaongororwazve nemanual ultrasonic uye X-ray. Kana pane kukanganisa, mushure mekugadzirisa, pombi ichaiswa pasi peNDT zvakare kusvikira yasimbiswa kuti zvikanganiso zvakabviswa.
(12) Pombi yebutt welding seam uye T-joint intersecting spiral welding seam ichaongororwa neX-ray terevhizheni kana kuongorora firimu.
(13) Imwe neimwe pombi yesimbi inoenderana neiyo hydrostatic bvunzo. Iyo yekumanikidza yekuyedza uye nguva inodzorwa zvakanyanya nekombuta yekuona mudziyo wesimbi pombi mvura kumanikidza. Test parameters inodhindwa otomatiki uye kurekodhwa.
(14) Iyo pombi inopera inogadzirwa kuti inyatso kudzora perpendicularity, bevel angle uye mudzi chiso.
