| Abstract: | The high pressure piping in offshore drilling systems always needs to use AISI 4130 or similar materials to meet relevant requirements.This type of piping lines work in adverse conditions and are strict with welding quality.Based on the analysis of welding properties of AISI 4130,through welding tests,and combined with the actual production capacity of the factory,a targeted AISI 4130 piping welding process and a PWHT process are worked out and summarized,including: welding process parameters,PWHT process parameters,weld welding sequences,welding repair process,by conducting some practical operational details and dealing with matters worth attention.By using this process,the requirement for welding under specific operating conditions has been fulfilled,and the practical experience in the construction of AISI 4130 steel piping has also been accumulated. |
