Seamless steel pipes have excellent product characteristics. Firstly, its most notable characteristics are its high strength and pressure resistance. Due to the absence of welding seams, seamless steel pipes can uniformly withstand pressure from all directions, making them particularly suitable for high-pressure and high-temperature working environments. The seamless steel pipes we produce adopt advanced production processes to ensure the mechanical properties of the pipes an

Seamless steel pipes have high strength and hardness, and can withstand significant pressure and impact. This is mainly attributed to strict manufacturing processes and high-quality raw materials. Secondly, the seamless steel pipes of Tianzhan Steel Pipe have excellent corrosion resistance and are suitable for fields such as petroleum, chemical, and power, which can improve their service life and reduce maintenance costs. In addition, the inner and outer walls of seamless ste

1. Raw material preparation: High quality steel billets are selected as raw materials, and after passing preliminary inspection, they enter the production line. 2. Hot rolling: Steel billets are rolled by a rolling mill at high temperatures to form capillary tubes. 3. Acid washing: Remove oxide scale and impurities on the surface of the capillary tube through acid washing. 4. Cold drawing: Cold drawing the pickled tube to gradually reduce the thickness of the tube wall, impro

Seamless steel pipes are required to have excellent wear resistance, machinability, heat resistance, and high strength and toughness of thick walled seamless steel pipes. In addition, some seamless steel pipes may decompose gases such as hydrogen chloride, hydrogen fluoride, and sulphur dioxide in a molten state, so the mould must have a certain degree of corrosion resistance. At present, domestic seamless steel pipe users generally choose 4Cr13 stainless steel. This study in

Seamless steel pipe production enjoys a high reputation in the market, especially for 20 * 2 precision pipes. The production process of precision tubes includes hot rolling, cold drawing, and precision rolling annealing. Each process has its unique advantages and application scenarios. Alloy seamless steel pipe: superior to ordinary hot-rolled seamless steel pipe Alloy seamless steel pipes are favoured for their high mechanical properties and hardness. Compared with ordinary

Seamless steel pipe is a type of steel pipe without welds, made by piercing a whole round steel. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold drawn seamless steel pipes, extruded seamless steel pipes, and top pipes. According to the cross-sectional shape, seamless steel pipes are divided into two types: circular and irregular. Irregular pipes include various complex shapes

The control of steel pipe wall thickness is a difficult point in steel pipe production, and measures to improve wall thickness accuracy in production mainly include the following aspects: 1. Tube billet heating Heating should be uniform, and rapid temperature changes are prohibited. Each temperature rise and fall should be kept steady and slow, with a maximum rise and fall temperature not exceeding 30℃. 2. Centering roller Confirm whether the centering roller is installed pro

The production process of low-temperature seamless steel pipes mainly includes the following steps: 1. Smelting: Using smelting equipment such as electric furnaces or converters, deoxidation, slag removal, and alloying treatment are carried out on molten steel to obtain pure molten steel. 2. Rolling: Injecting molten steel into a pipe rolling mill for rolling, gradually reducing the pipe diameter and obtaining the desired wall thickness, while also smoothing the surface of th

According to different production methods, it can be divided into hot-rolled pipes, cold-rolled pipes, cold drawn pipes, extruded pipes, etc. The biggest difference between cold drawn seamless steel pipes and hot-rolled seamless steel pipes is that the precision of cold drawn seamless steel pipes is better than that of hot-rolled seamless steel pipes. The general precision of cold drawn seamless steel pipes is around 20 threads, while the precision of hot-rolled seamless stee
