API SPEC 5L GB/T 9711.1 LSAW Steel Pipe In Pipe Oil And Gas
LSAW steel pipe is a straight seam submerged arc welded steel pipe. Its main technical characteristics are as follows:
1. During the steel tube forming process, the steel plate is uniformly deformed, the residual stress is small, and the surface is not scratched. The processed steel pipe has greater flexibility in the diameter and wall thickness steel pipe size specifications, especially in the production of high-steel-grade thick-walled steel pipes, especially large-caliber thick-walled pipes, which have unmatched advantages in other processes, which can meet Users have more requirements in terms of steel pipe specifications;
2. Adopting the pre-weld and then internal-outer welding (fine welding) process, welding can be achieved at the optimal position, which is not prone to defects such as misalignment, welding deviation and under-penetration, and it is easy to control the welding quality;
3. The overall mechanical diameter expansion can effectively improve the dimensional accuracy of the steel pipe and improve the distribution of stress in the steel pipe, thereby avoiding damage due to stress corrosion, and at the same time, it is beneficial to the welding construction on site;
4. Carry out 100% quality inspections on steel pipes, so that the entire process of steel pipe production is under effective detection and monitoring, effectively ensuring product quality;
5. All the equipment of the whole production line has the function of networking with computer data acquisition system, realizing the real-time transmission of data, and the central control room controls the production.
