Hydrostatic Test
Yese pombi yesimbi ichaongororwa hydrostatically uye hapazove nekudonha kubva kune welds kana pombi muviri panguva yekuedzwa.
Mapombi asina musono uye Welded simbi pombi ine OD≤457mm:Voltage kudzikamisa nguva ≥5s
Welded simbi pombi ine OD> 457mm:Voltage kudzikamisa nguva ≥10s
Mapombi esimbi ane shinda uye mabatanidza ane OD> 323.9 mm:Miedzo inogona kuitwa mu flat-end state.
