Manufacturing process of double flange welded steel pipe: welding, cutting, drilling
Double flange welded steel pipe is suitable for steel pipes of any diameter.
The double flange welded steel pipe has high mechanical strength, excellent corrosion resistance, small thermal expansion coefficient, good insulation and anti-interference performance.
The inner and outer surfaces of the double-flange welded steel pipe are sandblasted, which greatly enhances the adsorption force of the plastic and the base pipe, and is resistant to weathering and pressure.
Working temperature of hot water pipe: 0°C～75°. Cold water pipe working temperature: 0°C～55°. The performance indicators of the double flange welded steel pipe meet the requirements of the national standard and the sanitary standard of the Ministry of Health, and have certain flexibility.
The double-flange welded steel pipe is not easily deformed by extrusion, is resistant to collision, and has high installation reliability; the installation is convenient and reliable, and a flared socket and bimetal connection are added to the traditional connection.
Scope of application: Plastic-coated composite steel pipes can be used in coal mines, ventilation systems, fire-fighting water supply systems, air-conditioning HVAC circulating water pipelines, industrial water supply and drainage, domestic water supply and drainage, gas and other gas transportation, power wiring, chemical transportation pipelines and seawater treatment range of tubes.
