Introduction to Induction Bends
Pipe bends are essential components in piping systems, used to change the direction of the flow. They are widely applied in various industries, including oil and gas, water, chemical, and power.
Traditional pipe bending methods include bending, stamping, casting, and welding. These methods have advantages and disadvantages, but they all have some limitations, such as low forming accuracy, uneven wall thickness, affected material properties, and low production efficiency.
Induction bending is a pipe bend formed by heating and bending the pipe using induction heating technology. Compared with traditional pipe bending methods, induction bends have the following advantages:
- High precision and high quality: Induction heating technology ensures the bending’s forming accuracy and wall thickness uniformity, and the material properties are not affected.
- High efficiency and low cost: Induction bending has high production efficiency, energy saving, and environmental protection, and the overall cost is lower than traditional bending methods.
- Wide application: Induction bends can be applied to various industries such as oil and gas, water, chemicals, and power.
Induction Bends Material
The material of the induction bend should be selected according to the specific requirements of the piping system. Common materials include:
- Carbon steel: It is the most commonly used pipe bend material with good strength and toughness.
- Stainless steel: Stainless steel has the characteristics of corrosion resistance and high temperature resistance, and is suitable for piping systems in special environments.
- Alloy steel: Alloy steel has higher strength and wear resistance, and is suitable for harsh conditions such as high pressure and high temperature.
- Plastic: Plastic pipe bends are lightweight and corrosion-resistant, and are suitable for low-pressure piping systems.
- Other materials: According to special needs, materials such as titanium alloy and Hastelloy can also be used to manufacture induction bends.
Induction Bends Process
The manufacturing process of induction bends mainly includes the following steps:
- Cutting: Cut the pipe to the required length according to the requirements of the piping system.
