Cold Drawn Seamless Tubing is a kind of steel pipe. According to the production process, steel pipe can be divided into hot rolled tubing, Cold Drawn Seamless Tubing and hot-expanded seamless pipe. Cold Drawn Seamless Tubing is a steel pipe made of hollow billet or raw materials after multiple passes of cold drawing. The precision of Cold Drawn Seamless Tubing is high, which can improve the utilization rate of products and reduce the cost when it is used to make hydraulic machinery. 聽 What's the difference between hot rolled tubing and Cold Drawn Seamless Tubing? Hot rolled tubing is hot formed steel pipe, Cold Drawn Seamless Tubing is cold formed seamless steel pipe. Therefore, the mechanical properties of Cold Drawn Seamless Tubing without heat treatment are not as good as those of hot rolled tubing. The size tolerance of hot rolled tubing is large, and the precision of Cold Drawn Seamless Tubing is high. The production capacity of hot rolled tubing is high, so the price is low, and the production capacity of Cold Drawn Seamless Tubing is low, so the price is high. 聽 Where is the Cold Drawn Seamless Tubing mainly used? Because of its high accuracy, Cold Drawn Seamless Tubing can improve the utilization rate of its products. So can be widely used in a variety of mechanical processing production, such as: hydraulic pneumatic cylinder, jack, auto parts, fitness equipment, pipe joints and so on. 聽 How is Cold Drawn Seamless Tubing made?
