Product Features And Manufacturing Process
Product Features of Seamless Alloy Steel Tube
1. High precision: The size accuracy and shape accuracy of this steel pipe are very high, which can meet the requirements of various high precision application scenarios.
2. High strength: due to the use of high-quality alloy materials, it has high strength and can withstand greater pressure and impact force.
3. Corrosion resistance: the addition of alloy elements makes the steel pipe have good corrosion resistance. It can be used in a variety of harsh environments for a long time.
4. Good processing performance: it has good processability, can be cutting, bending, welding and other processing operations.
Manufacturing Process
1. Raw material preparation
· Material selection: according to the required steel pipe performance requirements (such as strength, corrosion resistance, high temperature resistance, etc.), select suitable alloy materials. These materials may include stainless steel, nickel-based alloys, titanium alloys, superalloys, etc.
· Smelting and casting: the selected alloy raw materials are smelted, and alloy ingots or billets that meet the requirements are obtained by adjusting the composition and process parameters.
2. Billet processing
· Heating and perforation: The worker will heat the alloy blank to the appropriate temperature. And then use a punch to punch to form a preliminary tube blank. Perforation methods may include hot rolling perforation, diagonal rolling perforation or tube jacking perforation.
· Pickling and passivation: pickling the perforated tube blank. The surface is removed of oxide scale and dirt and then passivated to improve its corrosion resistance.
3. Hot rolling and cold rolling
· Hot rolling: the tube billet is heated to a certain temperature in the heating furnace. And then rolled through the hot rolling unit, gradually reducing the pipe diameter and increasing the wall thickness until the desired size is reached. In hot rolling process, it is necessary to strictly control the temperature and rolling force to ensure the quality of pipe.
· Cold rolling: for seamless alloy steel tubes requiring higher precision and surface quality, cold rolling process can be used. Cold rolling is carried out at room temperature. The dimensional accuracy and surface quality of pipe can be improved by reducing pipe diameter and wall thickness gradually through multi-pass rolling.
4. Heat treatment
· Solution treatment: hot rolled or cold rolled steel pipes are treated with solution treatment to eliminate stress, homogenize structure and improve performance. This treatment usually includes steps such as heating, insulation and cooling.
· Aging treatment: For some alloys, such as superalloys and titanium alloys, factories need to age them to further improve their strength and stability. Aging treatment refers to holding at a certain temperature for a period of time, followed by natural cooling or rapid cooling to room temperature.
5. Test and cut
· Non-destructive testing: Conduct non-destructive testing on the steel pipe, such as ultrasonic testing, ray testing, etc., to detect whether there are defects inside the pipe.
· Size and appearance inspection: Check the size, wall thickness and appearance of the pipe. It can ensure that it meets the design requirements.
· Cutting and packaging: According to customer requirements, steel pipes are cut to the required length, and packaged and marked for transportation and storage.
