The use of stainless steel for the cylinder tube has the characteristics of small product design and long service life. Because stainless steel has high strength and corrosion resistance, compared with aluminum, iron and other materials, due to its high strength and non-magnetic, it can be designed to be lighter and thinner than aluminum and iron, which can reduce the size and weight of the product. It is more used for mini cylinders. .It is a portable automatic equipment. The inner and outer roughness of the stainless steel cylinder tube can reach Ra0.2-0.4μω, and the tolerance zone of the inner and outer diameter can reach 0.03mm; the specifications are from Φ3-Φ108mm, and the wall thickness is 0.2-3mm. 1. The main feature of seamless steel pipe is that there is no welding seam. Understand greater pressure. The product can be rough cast or cold drawn parts. 2. The cylinder tube is a product that has appeared in recent years, mainly because the inner hole and outer wall dimensions have strict tolerances and roughness. The characteristics of the cylinder tube: 1. The outer diameter is smaller. 2. High precision can be produced in small batches. 3. The cold-drawn product has high precision and good surface quality. 4. The horizontal area of ??the steel pipe is more complicated. 5. The performance of the steel pipe is superior, and the metal is denser.
