ASTM A53 steel yeeb nkab

ASTM A53 (ASME A53) carbon steel yeeb nkab yog ib qho tshwj xeeb uas npog seamless thiab welded dub thiab kub-dipped galvanized steel yeeb nkab nyob rau hauv NPS 1/8 "rau NPS 26. A 53 yog npaj rau siab thiab mechanical daim ntaub ntawv thiab kuj tau txais kev zoo tib yam. siv nyob rau hauv chav dej, dej, roj, thiab cua kab.

A53 yeeb nkab los ntawm peb hom (F, E, S) thiab ob qib (A, B).

A53 Hom F yog tsim los nrog lub qhov cub tawg vuam lossis tej zaum yuav muaj qhov txuas txuas ntxiv (Qib A nkaus xwb)

A53 Hom E muaj hluav taws xob tsis kam vuam (Qib A thiab B)

A53 Hom S yog cov yeeb nkab seamless thiab pom hauv Qib A thiab B)

A53 Qib B Seamless yog peb cov khoom siv ntau tshaj plaws nyob rau hauv cov lus qhia no thiab A53 yeeb nkab feem ntau tau lees paub rau A106 B Seamless yeeb nkab.
