What is a steel tube mill line machine?
The steel tube mill line can produce pipes from 4 mm to 660 mm in diameter and from 0.2 mm to 22 mm in thickness. Generally diameters above 219 mm are referred to as big size pipe mill machine.
The core advantages of steel tube mill line machine
Easy Operation
The whole welded pipe production line adopts PLC control and touch screen operation, equipped with Chinese and English interfaces (the language can be switched according to requirements).
Precision & Stability
The outer diameter deviation of the welded pipe should be within 0.02mm, the ovality deviation should be within 0.02mm, and the straightness of the welded pipe should be less than 0.8mm/m. The welding quality is stable, with no cracks.
Full Line Customization
We customize the unit combination, forming stands and auxiliary devices based on your required pipe sizes, raw materials and factory layout.
Perfect Service
You can get the feasibility program and plant layout design before purchase, and we will provide you with door-to-door installation and commissioning services to ensure that your machine can run perfectly.
Applications of steel tube mill line machine
High frequency steel tube mill line can produce round, square, rectangular, oval and special shaped pipes.Suitable for MS tubes, GI tubes, black tubes, high-strength steel tubes, etc. ERW steel pipes are used in a variety of applications, including oil and gas transport, water systems, structural applications, and automotive chassis components.
Main components of steel tube mill line
A simple welded pipe production line consists of these machines: uncoiler, shear butt welder, looper, forming welding and sizing equipment, flying saw, stacking system etc.
Uncoiling And Leveling System
Mainly used for unrolling and leveling coils of steel and feeding them into the production line.
Shearer& Butt Welder Station
When the previous coil of steel strip is used up and replaced by a new one, the irregular edges of the two coils need to be cut out and welded together to ensure continuous production.
Horizontal spiral accumulator
Used for temporary storage of steel strip to ensure the continuous operation of the production line.
Steel Tube Mill Forming & Welding & Sizing Section
- The forming, welding and sizing of high-frequency welded pipes are the core production processes.
- Forming is done by a series of rollers that gradually bend the flat steel strip into a tube, providing blanks for welding;
Welding utilizes high-frequency induction heating to melt the edges of the billet and then passes through the extrusion rollers to form a solid weld;
- Sizing adjusts the outer diameter and roundness of the pipe through the roll set to ensure dimensional accuracy and appearance quality.The three coordinate and cooperate to determine the performance and quality of welded pipe.
Flying Saw Cut Off Equipment
- Flying saws are responsible for cutting continuously produced steel pipes in-line at a set length.
- According to the cutting method, the flying saw is mainly divided into hot-cutting saw and cold-cutting saw.
- Hot cutting saw produces high temperature cutting by rotating the saw blade at high speed, which is fast, but the cut may have burrs.
- Cold cutting saw adopts the principle of cold milling, the kerf is flat and smooth, almost no burr, suitable for products with high quality requirements for tube ends.
Steel Pipe Stacking and Strapping Machine
- The stacking machine neatly arranges the cut steel pipes according to the set quantity and rules by means of an automated device, and stacks them into bundles of specified shapes, such as hexagonal packet stacking and square stacking.
- The strapping machine automatically bundles the stacked tube bundles, using steel or plastic bands to fix the bundles and prevent them from being loose or deformed during transportation and storage.
