Qib Steel
ASTM A53 Qib B yog ib qho ntawm feem ntau siv qib ntawm cov yeeb nkab steel. Nws yog tus cwj pwm los ntawm nws lub zog siab thiab kav ntev, ua rau nws haum rau ntau yam kev siv. Qib tau muab faib ua ob hom: Hom E (Electric Resistance Welded) thiab Hom S (Seamless). ERW kav dej yog tsim los ntawm dov steel los xij thiab welding lawv longitudinally, uas muab ib tug nqi - zoo tshuaj rau ntau daim ntawv thov.
Daim ntawv thov
Pipeline kev thauj mus los: roj thiab roj kav dej, dej, chav thiab cua
