Anti-corrosionwozungulira welded chitoliro ali ndi kuwotcherera mbali imodzi komanso kuwotcherera mbali ziwiri.Chitoliro chowotcherera chiyenera kuonetsetsa kuti kuyesa kwa hydrostatic, kulimba kwamphamvu kwa weld ndi kuzizira kopindika kuyenera kukwaniritsa zofunikira.

Msoko wowotcherera matako: Ndiwowotcherera wozungulira wopangidwa polumikiza zigawo ziwiri za mapaipi achitsulo palimodzi.

Msoko wowotcherera: Ndi msoko wowotcherera womwe umagwiritsidwa ntchito kukonza m'mphepete mwa matako asanafike kuwotcherera komaliza.

Msoko wowotcherera Mzere wachitsulo: Mzere wachitsulo wowotchera ndi msoko wowotcherera wa mbale yachitsulo kapena chingwe chachitsulo papaipi yachitsulo yozungulira.

Anti-corrosion spiral welded chitoliro amapangidwa ndi kugudubuza chitsulo chochepa cha carbon carbon structural iron kapena low-alloy structural steel strip mu chubu chopanda kanthu pa ngodya ina yozungulira (yomwe imatchedwanso kupanga ngodya), ndiyeno kuwotcherera msoko wa chubu.Ikhoza kukhala yopapatiza Mipata kubala lalikulu m'mimba mwake zitsulo mipope.Spiral steel pipe imagwiritsidwa ntchito popanga mapaipi amafuta ndi gasi.Mapaipi achitsulo ozungulira amawotcherera mbali imodzi ndi mbali zonse.Ma welded mapaipi azionetsetsa kuyesa kwa hydrostatic, kulimba kwa ma welds ndi ntchito zopindika zozizira kuti zigwirizane ndi malamulowo.
