What are the main machines in the steel pipe machine production line?

As an important industrial material, steel pipe has a wide range of applications in various fields. In order to meet market demand and improve production efficiency, various advanced machinery and equipment are used in the steel pipe production process. Let's take a look at the main types of steel pipe production machines and their functions.
I. Rolling mill
Rolling mill is one of the core equipment in steel pipe production, which is mainly used to roll billets into steel pipes. A rolling mill usually consists of multiple rolls, which are gradually deformed into steel tubes by continuous rolling of steel billets. The performance and precision of rolling mill directly affect the quality and dimensional precision of steel pipe.
Second, welding machine
In the process of steel pipe production, the welding machine is used to weld steel strips or plates into tube billets. The welding machine adopts high-frequency induction heating method to rapidly heat the edge of the steel strip or steel plate to the molten state, and then realizes continuous welding of the steel strip or steel plate through the extrusion roll. The performance of welding machine directly affects the welding quality and efficiency.
Three, straightening machine
The straightener is used to straighten the welded tube billet and eliminate the bending and distortion caused by the welding process. The straightening machine usually adopts the principle of multi-roll straightening, and through the adjustment and pressure of multiple straightening rollers, the steel pipe is gradually restored to a straight state during the straightening process.
Four, cutting machine
The cutting machine is used to cut the straightened steel pipe to a certain length. The cutting machine usually adopts the flame cutting or laser cutting method, which can quickly and accurately complete the fixed-length cutting of the steel pipe. The precision and efficiency of the cutting machine directly affect the yield and production efficiency of the steel pipe production.
5. Testing equipment
In addition to the above main production equipment, the steel pipe production process also needs to use a variety of testing equipment to detect the quality of the steel pipe. These testing equipment include ultrasonic flaw detectors, hydraulic testing machines, etc., which are used to detect internal defects, dimensional accuracy and mechanical properties of steel pipes.
