I-ASTM A53 B ERW Umbhobho weNtsimbiIsicelo
1 Uyilo lweZakhiwo: umbhobho owona mkhulu ngaphantsi kokutsalwa kwamanzi amaninzi aphantsi komhlaba xa iinqaba, iibhoyila, ukuhanjiswa kwamanzi ashushu njalo njalo.
2 Umatshini, iiseti zokuthwala, oomatshini bokulungisa kunye nezinye izincedisi.
3 Iklasi yoMbane: ukuhanjiswa kwegesi, i-conduit yamanzi yamandla amanzi.
4 Iityhubhu ezi-Anti-static izityalo zamandla omoya.
I-ASTM A53 B ERW Ipayipi yentsimbi ibandakanya ezi ntlobo namabakala alandelayo:
Uhlobo E—Electric-resistance-welded, Grades A and B
