Induction Pipe Bending

Apakah Lentur Induksi?

Induction bending is a precise and efficient method of bending pipes and tubes using localized heating. This technique employs an electric coil to generate an electromagnetic field that heats a specific section of the pipe or tube. Once the material reaches the appropriate temperature, it is drawn through a bending mechanism to achieve the desired angle and radius. The heated section is then rapidly cooled, typically using water or air quenching, to set the bend in place.

What Material Can Be Used?

Induction bending can be applied to a wide range of materials, termasuk:

• Keluli karbon: Commonly used in construction, saluran paip, dan pembuatan.
• Keluli Tahan Karat: Preferred in industries requiring corrosion resistance, such as food processing and pharmaceuticals.
• Besi aloi: Used for high-strength applications, including aerospace and automotive sectors.
• aluminium: Chosen for its lightweight properties and used in transportation and structural applications.
• Copper and Copper Alloys: Utilized in plumbing, electrical, dan sistem HVAC.
• titanium: Employed in aerospace, medical devices, and high-performance engineering applications.

The versatility in material compatibility makes induction bending suitable for diverse industrial needs.

Detailed Overview of Induction Bending

1. Process Description

Induction bending involves several key steps:

1. Heating: The pipe or tube is positioned within an induction coil, which generates an electromagnetic field. This field induces eddy currents within the material, causing it to heat up rapidly and uniformly along the targeted section.
2. Lenturan: Once the material reaches the desired temperature (typically between 800°C to 1000°C for steels), it is drawn through a bending arm or roller system that applies the required force to achieve the bend.
3. Cooling: The bent section is immediately quenched using water or air, which rapidly cools the material and sets the bend. This rapid cooling
