This type of pipe rolling is the most important element of production and construction structures. They are characterized by maximum reliability due to production without welding seams. Such pipes are very resistant to both physical and mechanical influences. All of the above guarantees improved operational characteristics. GOST 8732-78 (assortment) and 8731-87 (technical requirements) seamless pipes are heat-deformed pipes. They are used in mechanical engineering, during the manufacture of various structures, for pipelines and even as a semi-finished product for all kinds of vessels. A wide assortment and clear technical requirements allow the consumer to choose exactly the pipe he needs and to be completely sure of its quality. Hot-deformed seamless steel pipes are made from both carbon and alloy steel. The most popular steels: 30ХГСА, 35, 20, 20Х, 10, 09Г2С, 45 and 40Х. According to the standards, the supply of pipes with a diameter of 25 mm to 820 mm is provided. At the same time, the wall thickness is 2.5-75.0 mm. The length of the pipes, according to the State Standard, is 4.0-12.5 m. But at the moment, pipes with a diameter of 32-55 mm and a wall thickness of 3.0 to 75.0 mm are produced. GOST 8734-75 (assortment) and 8733-74 (technical requirements) seamless pipes are cold-formed pipes. Cold-drawn pipe is made from a billet heated to a relatively low temperature, which is subsequently subjected to drawing, stretching it and reducing the diameter and wall thickness. Unlike a "hot" pipe, it has a more precise geometry. Like hot-deformed, "cold" pipes are made of alloy or carbon steel grades 30ХГСА, 35, 20, 20Х, 10, 09Г2С, 45 and 40Х. According to the standards, the cold-formed pipe is produced with a diameter from 6 mm to 114 mm, and the wall thickness varies from 0.5 mm to 24 mm. Seamless pipes are metal-rolled products in which there are no joints (joints, seams) along the entire length. Steel pipes are indispensable in many situations and are in demand on the market, despite the popularity of products made of polymeric materials. Types of seamless products Stainless steel is a strong, reliable and durable material. Stainless steel pipes are widely used in everyday life and production. They are classified according to the following features: length: measured, unmeasured, multiples of size; steel grades; manufacturing method: hot-rolled and cold-rolled. The manufacturing process is carried out at metallurgical plants from blanks. The difference lies in the heat treatment technology: cold-drawn ones are processed after they have cooled down, hot-drawn ones are processed in a red-hot state. The quality of pipes is always at a high level, products are created in accordance with the requirements of GOSTs. Advantages of seamless pipes Among rolled metal products, seamless pipe is the sales leader. The main advantages of these products are: attractive appearance; the possibility of manufacturing with different wall thicknesses; tightness, resistance to temperature and pressure; tolerance to aggressive environments; safety and reliability. The quality of the pipes ensures a long service life. Applications Due to properties such as elastic deformation, strength, the scope of seamless pipes is quite wide: Food and chemical industry. High throughput, purity allows you to transport various liquids. Oil, coal, heavy industry. Aviation, space and defense sphere. Shipbuilding, auto and tractor building. Construction industry (supports). Water pipelines and gas pipelines. Interior design, furniture elements. The absence of seams in the pipes allows you to evenly distribute the load and makes them indispensable and reliable.
