ERW steel pipe is widely used in construction, bridge, machinery manufacturing, automobile manufacturing, oil and gas transmission and other fields. For example, in the field of construction, it can be used in steel structures, scaffolding, bridge supports, etc. In the field of mechanical manufacturing, this steel pipe can be used to manufacture various mechanical parts and piping systems. In the field of oil and gas transportation, it is used to transport oil and gas and other media.
Coil preparation: high quality steel plate or steel strip is selected as raw material, and after pretreatment (such as rust removal, cleaning, etc.), it is sent to the coil machine for winding.
High frequency welding: the edge of the crimp steel plate is heated to melting state by high frequency current, and then quickly pressed together to form a seamless weld. High frequency welding has the advantages of fast speed, high weld quality and no need to add welding materials.
Weld treatment: After the welding is completed, necessary treatment is carried out on the weld, such as removing burs and sanding, so as to improve the flatness and beauty of the weld.
Testing and inspection: Conduct various testing and inspection on steel pipes, including appearance inspection, dimension measurement, pressure test, etc., to ensure that the quality of steel pipes meets relevant standards and requirements.
Cutting and packaging: According to customer requirements, steel pipes are cut to the required length, and packaged and marked for transportation and use.
Efficient production: ERW steel pipe adopts automatic production line, which can realize continuous and high-speed production and greatly improve production efficiency.
Cost savings: reduced labor costs due to high degree of automation; At the same time, the resistance welding process does not require additional filling materials, reducing the cost of materials.
Precise CONTROL: DURING resistance welding, current, voltage, time and other parameters can be precisely controlled to ensure stable weld quality.
High consistency: the dimensional accuracy and surface quality of the steel pipe are uniform and consistent, meeting the requirements of high standards.
High utilization rate: The ERW process has a high utilization rate of raw materials and reduces material waste.
Environmental protection and energy saving: no harmful emissions in the process of resistance welding, meet the requirements of environmental protection; At the same time, efficient energy use also reduces energy consumption.
Wide application: suitable for a variety of industries, such as construction, oil, gas, automobile manufacturing, etc.
Flexible customization: Steel pipes with different specifications, wall thickness and length can be customized according to customer needs to meet diversified needs.
High strength: After strict heat treatment process, it has high strength and good toughness.
Corrosion resistance: anti-corrosion treatment can be carried out to improve the corrosion resistance of steel pipes and extend the service life.
