Hydraustatic Test:
The Steel Pipe should be tested Hydraulically One by One. Maximum Test Pressio est XX MPa. Sub Testi Impetus, Stabilitas Tempus Non Minus quam X S, Et Ferro Pipe non Leak. Vel Hydraulic Test restitui potest per Eddy Current Testis vel Magnetic Flux Leakage Testis.
Test nondestructive
Fistulae quod plus requirant inspiciendum ultrasonically inspiciendum est per unum. Post Negotiationem requirit consensum partium et specificatur in contractu, alia probatio non perniciosa addi potest.
Test adulatione
Fistulae exteriori diametro maior quam XXII Mm subicietur adulationi Test. Nulla visibiles Delaminatio, maculae albae, aut immunditie fieri debent Per totum experimentum.
Duritia Test:
Fistula Graduum P91, P92, P122, et P911, Brinell, Vickers, Vel Rockwell durities Testimoniorum erit in Specimine Loth.
