    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.

    Emva uvuma Le Umsebenzisi, The 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 wombhobho kumaBakala P91, P92, lukhuni iimvavanyo P122, kunye P911, Brinell, Vickers, okanye Rockwell ziya kwenziwa kwi sihlahla ukusuka yesamba ngasinye

    Bend Test:

    Kuba pipe kabani ubukhulu lidlula NPS 25 Yindlu ububanzi kwi wall ubukhulu ratio ngu 7.0 okanye ngaphantsi iya phantsi kovavanyo begoba endaweni uvavanyo flattening. Okunye pipe kabani ubukhulu ilingana okanye idlula NPS 10 unokunikwa uvavanyo begoba endaweni flattening test kuxhomekeke kwimvume salowo uyithengileyo
