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 hwakaparadzana uye huremu hwayo hahuzosiyane kupfuura 10% pamusoro kana 5.5% pasi pehuremu hwayo hwekufungidzira, huchiverengerwa pachishandiswa hurefu hwayo nehuremu hwayo pakureba kweyuniti.
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
Inopikisa corrosion uye zvakatipoteredza
Mune chero chirongwa chekuvaka, hupenyu hurefu uye kuvimbika kwezvinhu zvakakosha.S355 JR spiral simbi mapaipi anokunda panyaya iyi sezvo achinyanya kurwisana nekuora uye zvakatipoteredza.Simbi inoshandiswa mukugadzira inobatwa zvakanyanya kuti iwedzere kupikisa kwayo, ichiita kuti mapaipi aya ave akakodzera kune ese ari pamusoro- uye pasi-pasi-pasi.Kupikisa uku hakusi kungovimbisa kuvimbika kwepombi, asiwo kunoderedza zvakanyanya mari yekugadzirisa, zvichiita kuti ive sarudzo inodhura.
