Product Description

Product Description

Bend pipe

A pipe bend is a pipe fitting used to change the direction of a pipeline. It is widely used in the fields of oil, gas, liquid, and engineering bridge construction. The pipe bend is made by a complete set of bending equipment, which is mainly divided into two processes: cold bending and hot pushing.

Cold bending pipe

Cold bending is a method of plastically deforming straight pipes at room temperature without heating to achieve desired curvature/angle, suitable for general bending, esp. small/medium-diameter pipes.

Bending equipment applies bending moment to bend pipes in elastic-plastic state (inner compression, outer tension), with controlled external force size/mode, enabling forming to a predetermined radius.
Specifications 
Pipe diameter: DN15 - DN1200 (21.3mm-1219mm), etc. 
Wall thickness: between 2 mm and 20mm 
Bending radius: 1.5D, 2D, 3D, 4D, etc. 
Material: carbon steel, stainless steel, alloy steel, etc.

Hot bending pipe

Hot bending is a method of bending pipes by heating them to a certain temp, then using external force via bending devices to plastically deform them into desired shapes/angles, suitable for high-temp, high-pressure, large-diameter pipes.

Heating reduces yield strength and enhances plasticity/toughness, easing deformation. Controlling heating temp/time and external force enables accurate control of bending and complex shapes/angles.

Specifications 
Pipe diameter: DN20 to DN1200 (26.9mm-1219mm), etc. 
Wall thickness: between 3 mm and 20mm 
Bending radius: 1.5D, 2D, 3D, 4D, etc. 
Material: carbon steel, stainless steel, alloy steel, etc.

Specification

Model	Process	Attributes	Application
Model A	Cold bending	Suitable for small and medium - diameter pipes. Usually made of carbon steel, stainless steel, alloy steel, etc. The bending radius can be customized, commonly 3D, 5D, 10D. Bending angles include 15°, 30°, 45°, 60°, 90° etc., and can be custom - made according to requirements. High precision, smooth surface finish, no need for heating during processing, energy - saving, and environmental - friendly.	Ideal for applications where precise bending of small and medium - diameter pipes is required, such as in plumbing systems, automotive exhaust systems, and some precision machinery pipelines.
Model B	Hot Bending	Suitable for high - temperature, high - pressure, and large - diameter pipes. Materials include various steels, nickel - based alloys, etc. The bending radius and angle can also be customized according to different engineering requirements. The pipes have good mechanical properties after hot bending, with enhanced plasticity and toughness.	Widely used in industries like power plants (high - temperature and high - pressure steam pipelines), oil and gas transportation (large - diameter pipelines), and petrochemical plants where high - strength and large - diameter pipe bending is essential.
Model C	Medium frequency Induxtion Bending	Applies to a wide range of pipe diameters and materials, including carbon steel, stainless steel, etc. Can achieve uniform wall thickness during bending, especially suitable for producing small - radius (R≈D), thin - wall (t/D≈0.015) 180° elbows. High production efficiency, can produce multiple - angle bends on the same core rod.	Used in power, petroleum, chemical, and other industries where high - quality and complex - shaped pipe bends are needed, such as pipeline prefabrication in nuclear power plants and petrochemical refineries.
