test Izidingo

Hydraustatic Test:

I-Steel Pipe Ukuba ivavanywe Hydraulically One By One. I Maximum Test Ingcinezelo Ingaba 20 MPA. Under The Uvavanyo Pressure, The sinjalo Ixesha kufuneka ungabi ngaphantsi kwe-10 S, Kanti Steel Pipe Ngaba Not ukuvuza. Okanye I fracturing Test Ngaba buyiselwa Ngu Eddy yangoku Testing okanye Magnetic Flux Ukuvuza Testing.

Test Nondestructive:

Imibhobho ezifuna Okunye Ukuhlolwa Ukuba Be Ultrasonically kuhlola One By One. Emva zothethathethwano ezidinga imvume Of The Party Ke kucacisiwe Contract, Okunye Non-Eyenzakalisayo Uvavanyo inokongezwa.

Flattening Test:

Ngemibhobho Nge An engaphandle Ububanzi Ezingaphezu 22 Mm oyakuphathwa gadalala A Flattening Test. Akukho Delamination ebonakalayo, amatshatshazi amhlophe, Okanye ubumdaka Ukuba ngethuba Linga lonke.

Ukuqinisa Test:

Kuba Pipe Of kumaBakala P91, P92, P122, Ke P911, Brinell, Vickers, Okanye Tests Rockwell Ukuqina unokwenziwa A Specimen Ukusuka uLote ngalinye
