Using premium rolling plate as raw materials hot rolled pipe, after rechecking, is automatically molded and welded and is cleared burr away at the optimum melding temperature under the control of computer. Nondestructive-examination-passed pipes are heated to 910-950 in anoxic condition before discharging. Repeatedly rolled by stretch reducer the pipes are comprehensively uniform in metallurgical structure, grain situation, physical dimension and mechanical property. Our products are widely used in flow pipe of combustible and incombustible liquid, boiler and steel structure and supply a gap of home market.
