    Hydrostatic Test

    Hurefu hwega hwega hwepombi huchaedzwa nemugadziri kune hydrostatic pressure iyo inoburitsa mumadziro epombi kushushikana kusingasviki 60% yeiyo yakataurwa kushomeka kwegoho pakupisa kwekamuri.Kudzvanywa kunozotemwa neinotevera equation:
    P=2St/D

    Kusiyana Kunobvumirwa Muhuremu uye Zviyero

    Hurefu hwega hwega hwepombi huchayerwa hwakasiyana uye huremu hwayo hahuzosiyane kupfuura 10% pamusoro kana 5.5% pasi pehuremu hwayo hwekufungidzira, huchiverengerwa uchishandisa kureba kwayo uye uremu hwayo pahurefu hweyuniti.
    Iyo dhayamita yekunze haifanire kusiyana kupfuura ± 1% kubva kune yakatsanangurwa yekunze dhayamita.
    Ukobvu hwemadziro chero nguva haufanire kupfuura 12.5% ​​pasi peiyo yakataurwa madziro ukobvu.

    Urefu

    Single random urefu: 16 kusvika 25ft (4.88 kusvika 7.62m)
    Hurefu hwakapetwa kaviri: pamusoro pe25ft kusvika 35ft (7.62 kusvika 10.67m)
    Hurefu hwakafanana: musiyano unobvumidzwa ±1in

    Ends

    Mirwi yepombi inofanira kuiswa pachena, uye maburi ari kumigumo anofanira kubviswa.
    Kana iyo pombi inopera yakatsanangurwa kuve bevel inopera, kona ichave 30 kusvika 35 degree
