I. Manufacturing process
1. Raw materials: Precision Tubes raw materials are high-quality carbon steel, alloy steel and stainless steel and so on.
2. Manufacturing process: Precision Tube production process includes: raw material inspection, heating, piercing, rolling, heating treatment, straightening, crack detection, surface treatment and finished product testing. Among them, piercing is the most important one, which is carried out by heating the blank to soften it and then piercing it on the rolling mill to form a seamless tube.
3. Precision control: precision tubes need to be strictly controlled during the production process of dimensions and surface quality, because the improvement of precision can ensure that precision tubes are more stable and reliable in use, and reduce unnecessary losses.
Second, features
1. High precision: Small diameterPrecision Tube of the inner and outer diameter dimensions of the accuracy of 0.05mm, the wall thickness accuracy of 0.05mm or less, to ensure the stability and reliability of its application in various industrial fields.
2. Good surface quality: the outer surface of the precision tube is smooth and free of paint, and the inner surface is smooth and free of oxidized skin and other defects. This surface quality helps to improve the efficiency of transferring fluids and extends the service life.
3. High strength: due to the special treatment process of forging and quenching, precision tubes have high strength and good tensile and extrusion strength. Therefore, it is significantly better than ordinary steel tube in mechanical engineering applications.
Three, application
1. Automobile industry: precision tubes are widely used in automobile manufacturing, such as frames, front and rear bearing housings, exhaust systems and so on, which can improve the safety and performance of automobiles.
2. Aerospace: Precision Tubes are also widely used in national defense, aerospace and other high-tech applications, such as aircraft accessories, missile engine sleeves, satellite launch canisters (propellers).
3. Medical equipment: precision tubes are widely used in the field of medical equipment, such as surgical instruments, medical gas delivery piping, etc. They can provide high-precision, high-reliability services, and make an important contribution to the medical cause.
In short, Precision Tube is a kind of high-precision, high-quality seamless steel tube. It plays an important role in various industrial fields and can greatly improve production efficiency and economic benefits.
