Detailed Product Description
|
Seamless pipe is a metal pipe with seamless structure, which is
widely used in petroleum, natural gas, chemical industry, electric
power, aerospace and other fields. Compared with welded pipes,
seamless pipes have higher strength and pressure resistance, so
they perform well in high pressure and high temperature
environments. The manufacturing process of seamless pipe is very complex and needs to go through multiple process steps. First, select a high-quality billet and process it into a tube billet by hot rolling or cold drawing. Then, the surface treatment and quenching and tempering treatment of the tube blank are carried out through pickling, grinding and annealing processes. Finally, the tube blank is processed into a seamless tube by a piercing machine or an extrusion machine. Seamless pipe has many advantages. First of all, since the seamless pipe has no welds, there will be no corrosion and fatigue problems of the welds during use. Secondly, the inner and outer surfaces of the seamless pipe are smooth, and the frictional resistance is small, so the energy loss can be reduced when the fluid is transported. In addition, seamless pipes have high dimensional accuracy and can meet various engineering needs. According to different application requirements, seamless pipes can be made of different materials. Common materials are carbon steel, alloy steel, stainless steel, etc. Carbon steel seamless pipe has good toughness and weldability, and is widely used in oil and gas fields. Alloy steel seamless pipe is widely used in chemical and electric power industries due to its high strength and corrosion resistance. Due to its excellent corrosion resistance, stainless steel seamless pipes are widely used in food, medicine, aerospace and other fields. Seamless pipe plays an important role in the oil and gas industry. During oil extraction, seamless pipes are used to transport oil and gas to ensure its safe and efficient transport to its destination. Additionally, seamless tubing is used in drilling and cementing operations for oil and gas wells. In the chemical industry, seamless pipes are used to transport various chemical media to ensure the smooth progress of chemical production. In a word, seamless pipe, as a metal pipe with seamless structure, plays an important role in many fields. Its manufacturing process is complicated, but it has many advantages, such as high strength, strong pressure resistance, and high dimensional accuracy. Seamless pipes of different materials are suitable for different application fields, such as carbon steel seamless pipes for oil and gas fields, and alloy steel seamless pipes for chemical and power industries. Seamless pipes have broad application prospects in petroleum, natural gas, chemical and other industries. Zhengde hot-rolled seamless steel pipe is a long strip of steel with a hollow section and no joints around it. The steel pipe has a hollow cross-section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, seamless steel pipe is lighter in weight when the bending and torsional strength is the same. It is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes and automobile transmission shafts. , bicycle racks and steel scaffolding used in building construction, etc. The use of seamless steel pipes to manufacture ring parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing hours, such as rolling bearing rings, jack sets, etc., which have been widely used in steel pipes. Hot-rolled seamless steel pipe is also an indispensable material for various conventional weapons. Gun barrels, barrels, etc. must be made of steel pipes.
Three-roll pipe mill The seamless steel pipe produced by the three-roll mill for hot-rolling seamless steel pipe has high precision. Because of the cross-rolling with the mandrel, the rolling action is repeated many times in one pass, which greatly improves the accuracy of the wall thickness and is not easy to produce. Defects such as scratches, ears, and green lines; the flexibility in production is large, and the pass size can be changed with the help of the clutch of the roll. Adequate inventory Standing inventory of carbon seamless tubes, seamless special-shaped tubes, alloy seamless tubes, precision tubes. Various types of seamless steel pipes with a specification of 5-426*0.5-60mm and a length of 2-16m. The cold-rolled precision bright tubes produced by our factory have smooth appearance, uniform wall thickness, no oxide layer, and high precision. The inner hole of the steel pipe can be divided into round type, spline type, plum blossom type, etc. It is widely used in automobiles, motorcycles, electric power, petrochemicals, ships, aerospace, bearings, pneumatic components, oil cylinders, boiler equipment, medical equipment, fitness equipment and other industries. Attention to detail No matter how to choose the hot-rolled seamless steel pipe, its quality cannot be ignored. It must be noted that there should be no defects on the surface, such as small cracks or scars, etc., and that the thickness of the pipe wall is the same to ensure uniformity. The physical comparison is still very important. Only after the basic comparison of the physical objects is done, can the steel pipes that meet the needs be selected. The processing technology of each seamless steel pipe is different, which will also affect its application field. Now it is generally processed by cold drawing and hot rolling, and the processing effect of the two and the application of steel pipes will also have certain differences. Applicable scene Hot-rolled seamless pipes specifically include low and medium pressure boiler steel pipes, high-pressure boiler steel pipes, seamless steel pipes for ships, petroleum cracking steel pipes, seamless steel pipes for high-pressure fertilizer equipment, oil jacket steel pipes, pipeline steel pipes, hollow sucker rods, and ordinary fluid steel pipes. , structural seamless steel pipes and imported alloy steel pipes, etc., with rich varieties and complete specifications, widely used in petroleum, chemical, electric power, boilers, ships, machinery and other industries, and have been sold all over the world.
