ERW Pipe Manufacturing Process

Octal Pipe inonyatso kutevedzera zviyero zvepasi rose mukugadzira mapaipi eERW, uchishandisa otomatiki uye nehungwaru michina kuti ive nechokwadi chakagadzikana uye chakavimbika chigadzirwa kuita. Nzira yakakwana inosanganisira:

1. Raw Material Kuongorora & Kugadzirira

Mahwendefa esimbi anosangana neAPI, ISO, uye mamwe mazinga epasi rose anosarudzwa.
Kuumbwa kwemakemikari, zvivakwa zvemuchina, uye kuremara kwepasi kunoedzwa kuti ive nechokwadi chekuenderana.

2. Kucheka & Kuumba

Yepamusoro-midziyo yekucheka nemazvo inova nechokwadi chekururama kwedimensional.
Mahwendefa esimbi anokotamiswa zvishoma nezvishoma nekugadzira michina kuita denderedzwa pombi mabhii.

3. Yakakwirira-Frequency Resistance Welding

Mipendero inopisa kusvika kune imwe plastiki uye yakasungirirwa pamwe chete nekusvina rollers.
Zvazvino, voltage, uye kumhanya kwewelding zvinogadziridzwa otomatiki kuvimbisa dense uye inoenderera welds.

4. Kurapa Kupisa (Annealing / Normalizing)

Kubvisa kushushikana kwemaweld nekupisa-nzvimbo dzakakanganisika.
Inovandudza microstructure, kuoma, uye kutsemuka kuramba.

5. Nondestructive Testing & Inspection

Ultrasonic bvunzo (UT):inoona mukati weld defects.
Eddy ikozvino kuyedza (ECT):inozivisa kuputika kwepamusoro uye inclusions.
Kuongororwa kweHydrostatic:inosimbisa pressure resistance.
Dimensional kuongorora:kukora kwemadziro, ovality, kureba kushivirira.

6. Kukura, Kucheka & Kupedzisa

Kupfapfaidza kutonhora uye saizi inovimbisa kutenderera uye kutwasuka.
Mapombi anochekwa kureba sezvinodiwa nemutengi, ane chamfering uye deburring.

7. Surface Treatment & Coating

Kunhonga, kuputika kwepfuti, kana -mapendekete anodzivirira corrosion (3PE, epoxy powder) anovandudza kusaita ngura.

FAQ

Q: Ndeupi musiyano uripo pakati peERW neHFW pombi?

A: HFW inowanzobatwa semhando yemazuva ano yepamusoro-yakawanda yeERW-"ERW" ndiro izwi reamburera, ukuwo "HFW" inoburitsa-frequency welding method inoshandiswa.

Mubvunzo: Unoziva sei ERW pombi kudzvanywa kwechiyero?

A:Pressure capacity ndiyokuverengerwa, isina kugadziriswa-zvinoenderanaOD, ukobvu hwemadziro, uye zvinobvumidzwa kushushikanamaererano nekodhi yedhizaini (inowanzo shandisa Barlow-type equations), yozogadziridzwa tembiricha uye corrosion allowance; hydrotest inosimbisa kutendeseka kwekumanikidza kana ichidikanwa.

Mubvunzo: ERW pombi vs pombi isina musono - ndeipi yandinofanira kusarudza?

A:SarudzaERWapo welded pombi inobvumirwa uye unodainowirirana OD/WT uye ipfupi yekutungamira nguva; sarudzaisina musonoapo fungidziro ichichida kana kuti basa riripoyakanyanya kudzvanywa / tembiricha kana yakanyanya cyclic kurodha.

Mubvunzo: ERW inorevei mupombi yesimbi?

A:ERW inomiriraMagetsi Resistance Welded. Iyo inogadzirwa nekudziya mipendero yemitsetse nehigh-frequency currentnokuasundidzira pamwe chete kuti aite alongitudinal weld musono.
