Stainless steel seamless pipe is a long strip of steel with a hollow cross-section and no seams around its perimeter.
Manufacturing process and flow of seamless steel tubes:
Smelting > Billet > Rolling > Sawing > Skinning > Piercing > Annealing > Pickling > Coating > Cold Drawing > Trimming > Pickling > Storage
2. Seamless steel tube features:
It's clear from the above process flow: Firstly, the thicker the wall thickness of the product, the more economically and practically it becomes; conversely, the thinner the wall thickness, the higher the processing costs will be. Secondly, the product's process determines its limitations, such as generally low precision in seamless steel pipes: uneven wall thickness, low luster on both the inside and outside surfaces, high cost for cutting to fixed lengths, and difficulty in removing surface blemishes like pits and black spots. Thirdly, its inspection and shaping must be processed offline. Therefore, it showcases its superiority in high-pressure, high-strength, and mechanical structural applications.
