I-China iMveliso eNtsha yaseTshayina uMgangatho oLungileyo wokutshiza ipeyinti engenamthungo yentsimbi
Isishwankathelo
I-ASTM A106Gr.B umbhobho wensimbi ongenamthungo yintsimbi ephantsi kwekhabhoni esetyenziswa ngokubanzi, esetyenziswa ngokubanzi kwimizi-mveliso yepetroleum, imichiza kunye nebhoyila.Izinto eziphathekayo zineempawu ezintle zoomatshini.Isetyenziswa kakhulu ukuthutha ulwelo oluphezulu lobushushu obufana namanzi, ioyile, igesi, njl.
I-ASTM A106 ipayipi yensimbi engenamthungo ibandakanya iinkqubo ezimbini: ezibandayo zitsalwa kwaye zishushu ziqengqiwe.
Isicelo
Umbhobho wensimbi ongenamthungo wokusebenza okuphezulu kwe-ASTM A106, ilungele ukushisa okuphezulu
IBanga eliPhambili
IBanga lentsimbi yolwakhiwo lwekhabhoni ekumgangatho ophezulu: G.A,GR.B,GR.C
