What do you need to pay attention to when choosing pipe making machine？
Scope
When choosing pipe making machine, the most important thing to pay attention to is the scope of pipe making, including the thickness of pipe, diameter, etc
Techniques
Tube mill or pipe mill employ two unique methods to form seamless and welded structures from a wide range of materials, including iron and non-ferrous metals. Factories are classified according to volume, technology or the nature of materials. For example:
ERW (electric resistance welding)
Plasma Welding
Laser Welding
TIG (tungsten inert gasses) Welding
Monitoring and inspection equipment are crucial to quality assurance. Typical devices include eddy current or ultrasonic monitoring systems, flux leakage detectors, and optical or laser sensors. Integration of the equipment drives improved automation and control of the processes.
Applications
Tube mills or pipe mills serve an array of industries and applications, including:
Electrical or Gas transmission
Liquid transportation
Oil and gas drilling
Irrigation
Structural tubing
Petrochemical pipe
Medical
Hydroform tubing
Mechanical tubing
Exhaust pipes
Materials
After choosing the use of the pipeline, you can choose the appropriate material according to the use of the pipeline. Tube mills and pipe mills rely on steel as their primary raw material. Pipes are made out of many types of materials. It is up to the engineering company to determine the materials to be used in the process piping system. Materials are selected based on fluid, pressure, temperature and cost. Most pipelines used by industrial sectors such as oil and gas fall into the following categories:
Carbon Steel Pipes
Stainless Steel Pipes
Alloy Steel Pipes
Galvanized Iron Pipes
Other materials present in the steel alloy may include:
Aluminum
Manganese
Titanium
Tungsten
