Spiral welded pipes (saw) akaturikidzana panze, uye mazhinji acho anovigwa pasi pevhu kana achishandiswa, saka ari nyore kuita ngura uye kuita ngura. Kuti uve nechokwadi chekuyerera kwakanaka kwepombi, iyo spiral welded pombi inofanirwa kunge iine yakasimba corrosion resistance. Kana pombi yaita ngura, inokonzeresa kubuda kweoiri negasi, izvo zvisingazongokanganisa kutakura chete, asiwo kusvibisa nharaunda, uye zvinogona kutokonzera moto nekukuvadza. Spiral welded pombi vanogadzira vanokuudza nezve izvo zvinokonzeresa kuparara kwe spiral welded pombi:

Zvikonzero zvekuita ngura ye spiral welded pombi:

1. Corrosion failure.

Kana pombi inogadzirwa, zvinodikanwa kuita basa rakanaka rekuita basa rekudzivirira kana kushandisa zvakananga anti-corrosion spiral steel pipes. Chikonzero chekuora kwepombi ndechekuti anti-corrosion layer yepombi yakakuvadzwa. Kana iyo anti-corrosion layer uye pamusoro pepombi zvapatsanurwa, zvinokonzeresa kutadza kutadza. Iyi ndiyo zvakare mhando yemanera. Tinofanira kusarudza anti-corrosion spiral welded pombi kana tichitenga spiral welded pombi.

2. Pesvedzero yemamiriro ekunze.

Chinhu chikuru ndechekutanga kutarisa maitiro uye tembiricha yepakati yakatenderedza pombi, uye kana iyo yepakati yakatenderedza pombi inoora. Nekuti kuora kwepakati kunoenderana zvakanyanya neakasiyana ma microorganisms ari muvhu. Uye kana iri pombi refu-refu, hunhu hwenzvimbo yevhu hwakanyanya kuoma. Pamusoro pezvo, tembiricha yemhoteredzo iyo pombi iripo ichakanganisawo kukora kwe spiral welded pombi. Kana tembiricha yakakwira, corrosion rate inokwidziridzwa, nepo tembiricha yakadzikira, chiyero chekuora chinodzikiswa.
