Characteristics of spiral welded pipes with stainless steel reinforcing ribs used in underground coal mines

Views: 2    

1. The quality of the pipe is light: the pipe is made of a 1.5-3mm stainless steel strip, which reduces the weight of the pipe. 2. The safety performance of the pipe is high: the inner wall of the pipe is smooth, the flow capacity is strong, and the fluid resistance is small. 3. High strength of pipe structure: The welded seam structure of the pipe acts as a reinforcing rib and improves the strength of the pipe against negative pressure. 4. The pipe has good electrical conductivity: the pipe is made of stainless steel, which improves the life of the pipe and has an antistatic effect; 5. The particularity of the pipe: the unique occlusal structure during the pipe forming process makes the pipe during the coal mine gas transportation process, due to geological changes, displacement, or stretching, the occluding part releases 3%-6% of the length through extension, While ensuring that the gas does not leak. This is a feature that other ordinary metal pipes do not have. 6. The pipe is easy to transport and the installation cost is low.
