Bendability Test
Inoshanda kune mapaipi ane dhayamita yekunze ≤50 mm sezvakatsanangurwa nemutengi.
Mucherechedzo ngauve usina kuputika kana wakakotama pakona ye90 ° nepakati pedhayamita katanhatu kubva kunze kwepaipi.Kona yekukotama ichayerwa pakutanga kwekubhenda.
Hydrostatic Test kana Nondestructive Test
Muedzo we hydrostatic kana usinga paradza uchaitwa papombi imwe neimwe.
Hydrostatic Test
Bata pombi isingasviki pane yakataurwa yakaderera hydrostatic test pressure kweinenge 5 seconds uye tarisa kuti pombi inogona kumirisana nekudzvanywa pasina kubuda.
Kana Mutengi akasatsanangura kudzvanywa kwekuyedza, uye pombi painoiswa pasi peiyo shoma hydrostatic test pressure yakapihwa, pombi inokwanisa kumira nayo pasina kuvuza.

Kana iyo yakaderera hydrostatic bvunzo yekumanikidza yenhamba yechirongwa chakasarudzwa ichipfuura bvunzo yekumanikidza P yakawanikwa neformula, iyo yekumanikidza P ichashandiswa seyakaderera hydrostatic test pressure pachinzvimbo chekusarudza iyo shoma hydrostatic test pressure mutafura iri pamusoro.
Nondestructive Test
Iyo pombi ichaongororwa ne ultrasonic kuonekwa kana eddy ikozvino kuonekwa.
Kune ma ultrasonic ekuonekwa maitiro, masaini ereferenzi samples ane UD kirasi referensi zviyero zvakatsanangurwa muJIS G 0582 ichaonekwa seyero yearamu, uye hapana chiratidzo chakaenzana kana chikuru kupfuura chiyero chealarm chichavepo.
Kune eddy ikozvino yekuona maitiro, chiratidzo chereferenzi sampuli ine referensi chiyero chekirasi EY sezvakatsanangurwa muJIS G 0583 ichaonekwa searamu level, uye hapana chiratidzo chakaenzana kana chikuru kupfuura alarm level ichave iripo.
