摘要:
针对国内目前大直径输水钢管现场对接焊安装时出现的对接质量低、速度慢、焊接接口漏水等问题，结合国外应用经验，通过对承插搭接焊接口进行参数设计和受力分析，设计了一种大直径输水钢管承插焊连接方式，并通过试验模拟了现场焊接和试压。结果表明，钢管承插搭接焊连接可降低对接难度，提高对接速度和接口的密封性，以期为我国输水钢管的生产和安装提供更好的解决方案。
Abstract:
Aiming at the problems of low butt quality, slow speed and leakage of welding interface occurred in the field butt welding and installation of large diameter water transmission steel pipe in China, combined with foreign application experience, through the parameter design and force analysis of socket lap joint, a socket welding connection mode of large diameter water conveying pipe was designed, and field welding and pressure test were simulated by experiment. The test results showed that socket lap welding connection of steel pipe can reduce the difficulty of butt joint, improve the speed of butt joint and the tightness of the interface, and provide a better solution for the production and installation of water transmission steel pipe in China.
