Cov khoom siv twg yog A53 yeeb nkab sib npaug?
ASTM A53 Carbon Steel Seamless Pipe Specifications
ASTM A53 seamless steel yeeb nkab yog ib hom American standard hom. A53-F sib raug rau Tuam Tshoj cov khoom siv Q235, A53-A sib raug rau Tuam Tshoj cov khoom No.
ASTM A53 yog cov pa roj carbon steel hlau uas tuaj yeem siv los ua cov qauv hlau lossis cov kav dej tsis tshua muaj siab.
ASTM A53 (ASME SA53) Carbon Steel Pipe yog ib qho kev qhia tshwj xeeb uas npog seamless, welded dub thiab kub-dip galvanized steel yeeb nkab nyob rau hauv qhov ntau thiab tsawg NPS 1/8 "rau NPS 26. A53 yog haum rau siab thiab mechanical daim ntaub ntawv thiab kuj haum rau kev siv dav. nyob rau hauv chav dej, dej, roj thiab cua pipelines.
A53 kav dej muaj nyob rau hauv peb hom (F, E, S) thiab ob qib (A, B).
A53 Hom F yog tsim los ntawm lub qhov cub tawg welds lossis tej zaum yuav muaj qhov txuas txuas ntxiv (Qib A nkaus xwb)
A53 Hom E nta tsis kam vuam (Class A thiab B)
A53 S hom yog cov yeeb nkab seamless, muaj nyob rau hauv qib A thiab B)
