Flange connection spiral steel pipe

With the continuous advancement of urban infrastructure development, more and more various pipeline projects have begun to emerge. The connection methods of spiral steel pipes used in various pipeline projects are also different. Today we mainly introduce flange connection. Spiral welded steel pipes for pipeline engineering are made of high-quality steel plates through multiple processes such as curling, welding, and grinding. They have the characteristics of high strength, corrosion resistance, and strong pressure-bearing capacity. They are widely used in water supply and drainage, gas, heating, chemical industry, etc. industry.

The flange-type spiral steel pipe is made by welding a flange to both ends of the spiral steel pipe. It has the characteristics of convenient connection, convenient installation and strong adaptability. Can adapt to various special and complex working environments or terrains. But its disadvantage is that compared with ordinary welding connection methods, its price is relatively high.

Flange-type spiral steel pipes are often used for surface-mounted pipes. In order to improve the corrosion resistance of the inner and outer walls of the steel pipe and increase its service life, anti-corrosion processing is required. For example, polyurethane anti-corrosion, fiberglass anti-corrosion, plastic coating anti-corrosion, etc. The plastic coating anti-corrosion method is a new anti-corrosion method that has emerged rapidly in recent years.

Flange-type spiral steel pipes are suitable for urban water supply pipelines, drainage pipelines, and gas pipelines. Also suitable for petroleum, chemical, coal, mining, transportation and other industries. Due to its strong adaptability, easy installation, high strength, good anti-corrosion performance, reduced construction period and other characteristics, it plays an important role in various industries of modern construction and is an important pipeline material worthy of promotion.

Advantages of flange-connected spiral steel pipes:
1. High strength: Flange-connected spiral steel pipes are connected by spiral steel pipes and flanges. They have high strength and stiffness and can meet the needs of various high-strength pipeline projects.
2. Corrosion resistance: Since spiral steel pipes and flanges are made of steel, they are not susceptible to corrosion and damage. This connection method is more reliable for pipelines with various corrosive media.
3. Strong pressure-bearing capacity: The flange-connected spiral steel pipe adopts advanced welding technology to ensure the sealing and pressure-bearing capacity of the pipeline, and can meet the needs of various high-pressure pipeline projects.
4. Easy installation: The installation of flange-connected spiral steel pipes is relatively simple. You only need to connect the flange to the pipes and equipment and tighten the bolts. The installation is efficient and easy to maintain.
5. Wide range of applications: Flange-connected spiral steel pipes are suitable for various pipeline projects, such as water supply and drainage, gas, heating, chemical industry, etc., providing reliable pipeline connections for different industries.

Application areas of flange-connected spiral steel pipes:
1. Water supply and drainage projects: Flange-connected spiral steel pipes are widely used in water supply and drainage projects. They can withstand the pressure and vibration during pipeline operation, ensuring water quality safety and normal operation of pipelines.
2. Gas engineering: Flange-connected spiral steel pipes can be used to connect gas transmission pipelines. They have high sealing and pressure-bearing capabilities, and can ensure the safety and stability of gas transmission.
3. Heating projects: Flange-connected spiral steel pipes are widely used in heating projects. They can withstand high temperatures and high pressures and ensure the normal operation and heating effect of thermal pipelines.

4. Chemical engineering: Flange-connected spiral steel pipes are suitable for transporting various corrosive media in the chemical industry, such as acids, alkalis, salts, etc., providing a reliable pipeline connection solution for chemical production.
