A53 raj thiab A106 raj - (1) ntau yam
ASTM A53 yog tus qauv specification rau dub thiab kub-dip, galvanized, welded, thiab seamless tubing.
ASTM A106 yog tus qauv tshwj xeeb rau seamless carbon steel kav rau kev siv kub.
A53 yeeb nkab thiab A106 yeeb nkab - (2) yeeb nkab thov hom
53 tuaj yeem welded lossis seamless, nyob ntawm qhov xwm txheej thaum lub sijhawm yuav khoom. Nws yog ib tug dav hlau yeeb nkab specification, npog galvanized yeeb nkab thiab dub yeeb nkab.
A106 yog cov yeeb nkab uas muaj cov tshuaj zoo sib xws tab sis tsim nyog rau kev siv kub (txog 750 degrees Fahrenheit). Nws yog seamless raj.
Tsawg kawg hauv Tebchaws Meskas, feem ntau muaj A53 rau cov kav dej welded, thaum A106 tsis muaj seamless. Yog tias koj thov rau A53 hauv Asmeskas, lawv yuav hais A106 los hloov.
A53 raj thiab A106 raj - (3) Tshuaj muaj pes tsawg leeg
Piv txwv li, thaum peb piv A106-B thiab A53-B seamless los ntawm cov tshuaj muaj pes tsawg leeg foundations, peb pom tias:
1. A106-B muaj cov silicon tsawg tshaj plaws. 0.10%, ntawm uas A53-B yog 0%, silicon yog ib qho tseem ceeb hauv kev txhim kho cov txheej txheem cua sov.
2. A106-B muaj 0.29-1.06% manganese, uas A53-B muaj 1.2% manganese.
3. A106-B muaj cov ntsiab lus tsis tshua muaj leej faj thiab phosphorus, nrog rau cov ntsiab lus siab tshaj plaws ntawm 0.035%, ntawm A53-B muaj 0 .05% thiab 0.045% feem.
