Abstract
Abatract:Based on the φ1 422 mm diameter and X80 bend pipe composition design,pipe body and weld mechanical property and thermal processing performance research,several process parameters optimization of comparative trial,the optimization required reasonable push system and heat treatment process parameter,the matching of bending pipe body and weld mechanical properties and microstructure properties was realized.Produced the φ 1 422 mm×25.7 mm,X80 large diameter pipeline with hot bending bend samples that meet "CDP-S-OGP-PL-016-2014-3" general technical condition of oil and gas pipeline engineering induction heating bend requirements,and passed the national type test certification.关键词
