The automotive industry extensively relies on stainless steel pipes, particularly in the exhaust system. In fact, more than half of the total automotive stainless steel used is allocated for this purpose, with 80% of it being made of ferritic stainless steel. The exhaust gas produced by the vehicle's engine eventually makes its way out of the muffler through various components such as the exhaust gas intake pipe, front pipe, hose, converter, and center pipe. Popular steel grades used in exhaust systems include 409L and 436L. Stainless steel welded pipes are predominantly utilized in automobile mufflers. Statistics show that stainless steel pipes used in automobiles make up about 1.5% of the overall downstream consumption of stainless steel pipes, and the ratio of stainless steel seamless pipes to welded pipes is approximately 2:1.
Stainless steel welded pipe production process:
The process of manufacturing decorative welded pipes starts with the procurement of raw materials. These raw materials are then slit to the appropriate size, which is followed by the welding of pipes. After welding, the pipes go through a trimming process and are then polished. Once the polishing is complete, the pipes undergo inspection to ensure quality. The next step is spray printing, after which the pipes are packaged and shipped to the warehouse. From the warehouse, the pipes are sent out for distribution.
The manufacturing process for industrial piping of welded pipe starts with obtaining raw materials. These materials undergo the slitting process to achieve the desired width. The slitted pieces are then welded together to form the pipe. Heat treatment is applied to enhance the pipe's strength and durability.
After the heat treatment, the pipe goes through a straightening process to ensure its alignment. This is followed by another round of straightening to eliminate any remaining deformities. To achieve the desired length, the ends of the pipe are trimmed accordingly.
The pipe then undergoes pickling to remove any impurities or oxides on its surface. This is crucial to maintain the pipe's corrosion resistance. To ensure its quality and integrity, a hydraulic pressure test is conducted. This test evaluates the pipe's ability to withstand pressure and identifies any potential leaks.
Once the inspection is completed, the pipe goes through a printing process for necessary marking and identification. To protect the pipe during transportation, it is carefully packed. Finally, the pipes are ready for shipment to their intended destination.
According to the shape of the longitudinal section, stainless steel pipes can be categorized into equal-section pipes and variable-section pipes. Variable section tubes encompass tapered tubes, stepped tubes, and periodic section tubes.
