 ASTM A178 Electric Resistance Welded Tube Welded Pipe & Tube

ASTM A178 Electric Resistance Welded Tube


ASTM A178 standard referes to electric-resistance-welded tubes with minimum-wall-thickness. Materials are carbon steel and carbon-manganese steel, ASTM A178 pipe and tube is to be used in boiler tubes, boiler flues, superheater flues and safe ends. Steel Grades A (low-carbon steel), C (medium-carbon steel), or D (carbon-manganese steel). Manufacturing processes must include heat treatment, welding after cooling. Crush test shall be performed if required by customer.

Tiancheng Group exports erw pipes and tubes of different sizes and shapes,the same as other welded and seamless pipe, erw pipes or tubes can be delivered as beveled, threaded, coupled,surface treatment as black, bare or protective coating. Erw pipe and tubes also available in other steel grades: ASTM A53 structual pipe, API 5L line pipe, ASTM A252 pilling pipe.

Tiancheng supplies ASTM A178 erw tube as precision tube which applicated in boiler, superheater, heat exchanger tubes,if you need other precision tubes for engineering purposes, read boiler tube and pipe product or send quotation now.
