1. Pasi pemamiriro ekusakanganisa kusungirirwa kwemhuno, kureba kwakachengetwa kwepoxy powder pamagumo e polyethylene layer inofanira kuwedzerwa zvakakodzera kudzivirira 3PE anti-corrosion warping inokonzerwa nekugara kwenguva refu kwepombi yesimbiuye iyo yakakomba yesimbi corrosion yepombi inopera.

2. Kana mapaipi anodzivirira kupisa akaturikidzana mumhepo yakashama kwenguva yakareba, anofanirwa kuvharwa pamagumo epombi kudzivirira mvura inonaya kubva mukuora uye kukonzera kukanganisa kwakanyanya kwepombi inopera.

3. Kana nguva yekuvakwa kwepombi yakareba, pendi inokwenenzverwa yekudzivirira ngura inogona kupendwa pasimbi isina chinhu yepombi inopera kudzivirira iyo 3PE anti-corrosion layer kuti irege kuputika nekuda kwekuora panguva yekuchengetedza.

4. Nyatsodzora kunaka kwekukuya kwewelding seam yakachengetwa pamagumo epombi.Iko kunze kwe polyethylene groove pa weld yakafanana nedzimwe nhengo dzemuviri wepombi.Chengetedza epoxy poda yakareba kudarika 20mm kudzivirira pasi pe epoxy powder pane weld kubva pakutanga kusvibiswa uye kukonzera 3PE anti-corrosion layer ye warp.

Kuchenjerera kunofanira kubhadharwa pakukuya kwepombi end welds:

1) Kubva pakatanga kugezesa musono kukuya kune polyethylene chamfer, panofanirwa kuve nechikamu chakati sandara che polyethylene layer ye 10-20mm isina yakawedzera weld kureba uye zvakafanana nemuviri wepombi kuti ive nechokwadi chekubuda uye kubatana kwe polyethylene. groove pane pombi kupera kunaka.

2) Kusimbiswa kwe weld seam mushure mekugaya kunofanira kunge kwakanyanyisa sezvinobvira nemuviri wepombi, uye hapafanirwe kuve nekusimbisa kuri pachena kudzivirira epoxy poda kubva pakupepereswa pakukuya chamfer ye polyethylene layer.

3) Iyo chamfer yekumusoro isina kupfekedzwa weld uye chikamu chekuchinja chenzvimbo yakagadziriswa inofanirawo kunge yakafanana nechamfer ye polyethylene layer (≤30°) kuitira kuti simba rekusvina rekusvina roller rinokwanisa kupindirana ne polyethylene layer Kudzivirira polyethylene layer kubva pakuputira nekuda kwekusagadzikana kwekunamatira kwe-anti-corrosive layer pa groove.

5. Iyo epoxy powder coating yechikamu chakachengetwa inogona kunonoka kumucheto warping kunokonzerwa nekuora chete kana kudzivirira kwapera.Domestic pombi kupera polyethylene bevel processing inoitwa nesimbi waya vhiri kugaya, izvo zvinokuvadza epoxy poda coating.Iyo bevel inofanira kugadzirwa pachinzvimbo, uye iyo yepasi pasi yebanga-mupendero inofanira kuganhurirwa nechishandiso chekudzora kudzika kwekucheka kwechishandiso, kuti usakuvadza epoxy poda coating.
