摘要:
为了探究机械式双金属复合管进行Reel-lay海底管道铺设的可行性,模拟Reel-lay铺管过程,采用全尺寸静态弯曲试验机对Φ219.1 mm×(14.3+3.2) mm L450Q+316L机械式双金属复合管进行了循环弯曲试验。通过复合管弯曲应力应变测试,证明本试验装置完全可以模拟复合管Reel-lay铺设过程的弯曲变形。同时,对复合管弯曲前后的金相组织、拉伸性能、硬度和冲击性能进行检测,结果表明Reel-lay铺设过程中弯曲变形对该管材的理化性能影响较小,采用Reel-lay铺设方式是可行的。
Abstract:
In order to explore the feasibility of mechanical bimetallic composite pipe for Reel-lay submarine pipeline laying, the cyclic bending test of Φ219.1 mm×(14.3+3.2) mm L450Q + 316L mechanical bimetallic composite pipe was carried out using full size static bending testing machine to simulate the Reel-lay laying process. Through the stress-strain test of the bending of the composite pipe, it is proved that the experimental device and method can fully simulate the bending deformation of the actual Reel-lay laying process during the test. Meanwhile, through the test of the microstructure, tensile property, hardness and impact property of the composite pipe and butt weld before and after bending, it is shown that it has little influence on the performance of the mechanical composite pipe. The results show that the Reel?ay method is feasible for the mechanical bimetallic composite pipe.
