Specifications of Hot Induction Bends

Hot induction bends come in various specifications to cater to different requirements in the piping industry. Let’s take a closer look at some of the key specifications:

Pipe Diameter (O.D)

The pipe diameter for hot induction bends can range from a minimum of 2″ (60.3 mm) to a maximum of 60″ (1524 mm). This wide range allows for flexibility in designing and implementing piping systems.

Seamless Bend

Seamless bends are available in sizes ranging from 1/2″ to 24″. These bends are manufactured without any welding, resulting in a smooth and continuous flow path.

ERW / Fabricated/ Welded Bend

For larger pipe sizes, ERW (Electric Resistance Welded) or fabricated/welded bends are used. These bends are available in sizes ranging from 2″ to 36″.

Radius

The radius of a hot induction bend can vary from a minimum of 100 mm to a maximum of 11000 mm. The choice of radius depends on the specific requirements of the piping system.

Wall Thickness

Hot induction bends can accommodate a maximum wall thickness of 200 mm. The available wall thickness options include 3mm to 40mm, as well as various standard schedules such as SCH5, SCH10, SCH20, SCH30, SCH40, STD, SCH80, XS, SCH60, SCH80, SCH120, SCH140, SCH160, and XXS.

Hot Bend Heating System

The maximum heating capacity of the hot bend heating system is 1030 KW. This ensures efficient and precise heating of the pipe during the bending process.

Bending Capability

The bending capability of hot induction bends is impressive, with a capacity of 15,000 metric tons per year. This high capacity allows for large-scale production to meet the demands of various industries.

Pipe Bend Radius

Hot induction bends are available in different bend radii, including R=1D, 2D, 3D, 5D, 6D, 8D, 10D, or custom radii. The choice of bend radius depends on factors such as the fluid being transported and the space constraints of the piping system.

Straight Length L

The straight length of a hot induction bend can vary between 300mm and 1500mm. This straight length is essential for proper installation and connection of the bend within the piping system.

Pipe Bend Angle

Hot induction bends can be bent at any angle between 0° and 180°. This flexibility allows for precise alignment and redirection of the fluid flow.
