Classification of tube making machines

Tube making machines are mainly used to produce welded steel tubes. According to different classification standards, they can be divided into the following types:

Classification by welding method

High frequency Tube Making Machine (HF welding): uses high frequency current to heat the edge of the steel strip and weld, commonly used in the production of carbon steel tubes and stainless-steel tubes.

Straight seam submerged arc making machine (LSAW): uses submerged arc welding process to produce straight seam steel tubes, suitable for large diameter thick wall tubes.

Spiral submerged arc making machine (SSAW): uses spiral forming and submerged arc welding, suitable for large diameter transmission tube lines.

TIG making machine (TIG welding): used for precision welding of stainless steel and non-ferrous Metal Tubes, with high weld quality but slow production speed.

Classified by production process

Cold Forming tube making Machine: The cold-bending process is used to manufacture tubes, which is suitable for the production of small and medium-diameter steel tubes.

Hot rolling forming making machine: forming through hot rolling process, suitable for the manufacture of thick-walled tubes and large-diameter steel tubes.

Classified by use

Ordinary structural tube making machine: produces steel tubes for buildings, bridges, and mechanical structures.

Fluid transport tube making machine: produces welded tubes for water, oil, gas and other fluid transport, such as API standard tubes.

Precision tube making machine: produces tubes with high precision requirements for automobiles, home appliances, medical equipment, etc.

Classified by degree of automation

Manual tube making machine: more manual operation, suitable for small batch production.

Semi-automatic tube making machine: some processes are automated to improve production efficiency.

Fully automatic tube making machine: fully automated production, suitable for large-scale industrial production.

Different types of tube welding machines are suitable for different industries and needs, and they need to be selected based on factors such as materials, specifications, and uses.

The difference between decorative tube welding machine and industrial tube welding machine

The main differences between decorative tube welding machines and industrial tube welding machines are reflected in the use, process requirements, equipment configuration and product quality, as follows:

Different Uses

Decorative tube making machine: mainly produces Stainless Steel Tubes for home decoration, building decoration, furniture manufacturing and other fields, such as handrails, guardrails, door and window tubes, cabinet tubes, etc.

Industrial tube making machine: used to manufacture stainless steel tubes that need to bear pressure, corrosion resistance and high strength, widely used in food, medicine, petrochemical, boiler heat exchangers, automobile exhaust tubes and other industries.

Different Process Requirements

Decorative tubes: The aesthetics of the weld is high, and they are usually ground and polished to make the surface smooth and flawless, but the mechanical properties and pressure resistance of the tube are relatively low.

Industrial tubes: The strength, sealing and corrosion resistance of the weld are high, and the welding process is more stringent. Some industrial tubes need to be annealed to improve the mechanical properties, and more precise dimensional tolerances are required.

Different Device Configuration

Decorative tube making machine: generally adopts high frequency welding or argon arc welding, the equipment structure is relatively simple, and is often equipped with an online polishing device to ensure the beauty of the weld.

Industrial tube making machine: usually adopts argon arc welding (TIG), plasma welding (Plasma), laser welding and other precision welding technologies, and some are also equipped with solution annealing equipment to ensure the mechanical properties and corrosion resistance of the tube, and the equipment is more complex.

Different Production Standards

Decorative tubes: mainly follow the decoration industry standards, such as GB/T 18705, GB/T 12770, etc., with strict requirements on appearance quality.

Industrial tubes: need to meet higher industry standards, such as GB/T 14976 (stainless steel tubes for fluid transportation), ASTM A312 (industrial stainless steel seamless and welded steel tubes), and some industries such as food and medicine also need to meet special hygiene standards.

Different Quality Testing

Decorative tubes: Generally, basic indicators such as wall thickness, outer diameter, and weld appearance are tested, and strict non-destructive testing is rarely performed.

Industrial tubes: More stringent quality testing is required, such as water pressure testing, X-ray flaw detection, ultrasonic testing, corrosion resistance testing, etc., to ensure the safety and reliability of the tubeline.

In summary, decorative tube making machines focus more on appearance and are suitable for applications with light structures and high aesthetic requirements, while industrial tube making machines emphasize pressure resistance, corrosion resistance and mechanical properties and are used in high-standard industrial scenarios. When choosing, you need to decide on the appropriate equipment type based on specific production needs.

Main Difference between Laser Tube Making Machine and High Frequency Tube Making Machine

The main differences between laser tube making machines and high-frequency tube making machines are welding methods, application range, welding quality and equipment cost:

Welding Methods

Laser tube making machine: uses a high-energy laser beam as a heat source to complete welding by melting the metal, usually using fiber laser or CO2 laser.

High frequency pipe making machine: uses high frequency current (usually 100~800kHz) to induction heat the steel strip, melts its edge and then pressurizes and forms it for welding.

Welding Quality

Laser tube making machine: The weld is narrower, the heat-affected zone is smaller, and the welding accuracy is higher. It is suitable for high-requirement precision tube manufacturing, such as in the fields of medical, electronics, aviation, etc.

High frequency tube making machine: The weld is wider and the heat affected zone is larger, but the welding strength is higher, which is suitable for large-scale industrial production, such as construction, automobiles, oil pipelines, etc.

Application Range

Laser tube making machine: suitable for welding high value-added materials such as stainless steel, aluminum alloy, titanium alloy, etc., and is often used in precision manufacturing industry.

High frequency tube making machine: mainly used for the manufacture of welded pipes made of carbon steel, stainless steel and other materials, widely used in construction, pipelines, automotive industry and other fields.

Equipment Cost and Energy Consumption

Laser tube making machine: the equipment cost is high, the operation and maintenance cost is high, but the energy consumption is relatively low, and it is suitable for high-end manufacturing with high precision and low output.

High-frequency tube making machine: relatively low equipment investment, suitable for mass production, but high energy consumption.

Production Efficiency

Laser tube making machine: high welding speed, but limited by material characteristics and process requirements, usually suitable for small and medium-sized batch production.

High frequency tube making machine: the production speed is fast, suitable for mass continuous production, especially in the industrial application with low-cost demand.

Summary

If high-precision, high-quality welding is required, suitable for high-end materials such as stainless steel and titanium alloy, laser tube making machine is more suitable.

If large-scale production is required, high efficiency and low cost are pursued, suitable for ordinary steel pipe manufacturing, high-frequency tube making machine is more cost-effective.
