Imtixaanka Hydrostatic
Tuub si loo hor istaago baaritaanka biyo-baxa adigoon ka daadanin ku-daynta godka weldka ama jirka tuubbada. Wada-baxayaasha uma baahna in hawo-haynta lagu tijaabiyo siinta qaybaha tuubbada la isticmaalay si guul leh loo tijaabiyey.
Tijaabada Bend
Cill dildilaaca ma dhici doonaan qayb kasta oo ka mid ah gabalka imtixaanka oo aan furin ka mid ah weldku wuu dhici doonaa.
Imtixaanka Flatten
Shuruudaha aqbalitaanka ee imtixaanka jilicsan ayaa noqon doona:
- EW TIPES D <12.750 IN:
- X60 oo leh t 500in. Ma jiri doonto dhagaxa weld oo ka hor inta aysan masaafada u dhexeerin taargooyinka ay ka yar tahay 66% ee dhexroorkii dibedda. Dhamaan buundooyinka iyo darbiga, 50%.
- Tuubbada leh D / T> 10, ma jiri doonto dhagaxa weld ka hor intaanay masaafada u dhexeeynin taarikada ay ka yar tahay 30% dhexroorkii dibedda.

Imtixaanka Saamaynta CVN ee PSL2
Cabbirro badan oo PSL2 ah iyo buundooyin ayaa u baahan CVN. Tuub fadhiisi oo aad u jajaban waa in lagu tijaabiyaa jirka. Tuubbada dharka lagu xiro waa in lagu tijaabiyaa jirka, ppe weld iyo aagga kuleylka kuleylka leh.
