Umkhiqizo Omusha WaseShayina I-China Yekhwalithi Enhle Futha Ngopende Okungenamthungo Wensimbi
Uhlolojikelele
I-ASTM A106Gr.B ipayipi lensimbi engenamthungo iyinsimbi enekhabhoni ephansi esetshenziswa kakhulu, esetshenziswa kakhulu ezimbonini ze-petroleum, amakhemikhali, kanye namabhayela. Impahla inezici ezinhle zemishini. Ikakhulukazi esetshenziselwa ukuthutha uketshezi lokushisa eliphezulu njengamanzi, uwoyela, igesi, njll.
Ipayipi lensimbi elingenamthungo le-ASTM A106 lihlanganisa izinqubo ezimbili: ukudonsa okubandayo nokugoqwa okushisayo.
Isicelo
Ipayipi lensimbi engenamthungo yokusebenza okuphezulu kokushisa kwe-ASTM A106, efanelekile ukushisa okuphezulu
Ibanga Eliyinhloko
Ibanga lensimbi yesakhiwo sekhabhoni yekhwalithi ephezulu: G.A,GR.B,GR.C

Isidingo Sokuhlola
Ngokungeziwe ekuqinisekiseni ukwakheka kwamakhemikhali kanye nezakhiwo zemishini, ukuhlolwa kwe-hydrostatic kwenziwa ngakunye, futhi kwenziwa ukuhlolwa kwe-flaring ne-flattening. .
