    Tsananguro pfupi:

    Kana zvasvika kune zvakasikwa gasi rekufambisa, masisitimu epaiti anotamba basa rakakosha mukuita kuti kuve nekukwezva uye kushanda kwakakodzera kweichi chinokosha chishandiso.Yakasikwa gasi pombi Kusarudzwa isarudzo yekutsoropodza sezvo inokanganisa zvakananga kuvimbika uye kuchengetedzwa kwegasi rese rekuparadzira network. Mune ino blog, isu tinodzungudza mukukosha kwemhando yemhando yeiyo gasi pombi, kutarisa pa x42 Ssaw pombi, ASTM A139, uye en10219.

     X42SSAWpombiIrwo rudzi rwechisikigo gasi pombi inowanzo shandiswa mumafuta negesi indasitiri. Iyo yakagadzirwa uchishandisa yakanyungudutswa Arc Welding maitiro ayo anogadzira pombi dzakakwirira uye dzakasimba. X42 SSAW PIPE ine yakanyanya Simba uye yakanakisa makemikari zvivakwa, ichiita kuti ive yakakodzera kune zvinodiwa zvinodiwa zveganda rechisikigo. Kupokana kwaro kwakanakisa kuCorrosion uye kupaza kunoita kuti ive yekutanga sarudzo yemapipi ekuvaka.

     ASTM A139Imwezve mwero wakakosha wezvisikwa zvegesi dzepapa. Iyi sarudzo inovhara Electropulion (arc) yakaiswa yakatwasuka kana kuti yakasarudzika seam simbi pombi inoshandiswa kuburitsa magasi, steam, mvura uye zvimwe zvinwiwa. ASTM a139 pombi inozivikanwa nekuvimbika kwayo uye kwenguva refu kuita pasi pemamiriro ezvinhu akaomarara. Iyi pombi yakagadzirirwa kutsungirira dzakanyanya kudzvinyirira uye tembiricha dzinotonhora, dzichiita kuti vakwanise kuve vakanakira kutapurirana kwegasi kwegasi uye kugovera zvikumbiro.
