ASTM A53 Qib A yog dab tsi?
Nws yog qhov tsim nyog rau kev siv vuam thiab tsim cov haujlwm uas suav nrog coiling, dabtsi yog khoov thiab flanging, raws li qee qhov kev tsim nyog. A53 npog seamless thiab welded, dub thiab kub-dip galvanized nominal (nruab nrab) phab ntsa yeeb nkab rau coiling, dabtsi yog khoov, flanging thiab lwm yam tshwj xeeb lub hom phiaj, thiab yog haum rau welding.
ASTM A53 Qib A steel yeeb nkab yog hais txog cov txheej txheem txawv teb chaws steel yeeb nkab qib, uas yog qib Asmeskas tus qauv, cov A53-A sib raug rau cov khoom siv hauv tsev 10#.
ASTM A53 Qib A steel yeeb nkab tau muab faib ua ob hom: A53-A thiab A53-B. A53-A yog cov pa roj carbon tsawg thiab A53-B yog nruab nrab carbon steel. ASTM A53 steel yeeb nkab yog siv los thauj cov kua dej, xws li dej, roj, cua, roj thiab cua sov. Nws tau muab faib ua ob hom: seamless steel yeeb nkab thiab welded steel yeeb nkab. Kev tsim cov txheej txheem ntawm seamless steel yeeb nkab tuaj yeem muab faib ua kub dov thiab kos duab txias. Muaj ob hom. Nws cov yeeb nkab kawg suav nrog lub tiaj tiaj, threaded kawg thiab qhov (socket) kawg.
