Products Description

Cold bending welded round carbon steel pipe is a high-quality product designed to meet the needs of businesses looking to various types of mechanical steel pipes. The welded round carbon steel pipe offers a range of features and benefits that make it an ideal choice for businesses of all sizes.

Cold bending welded carbon round steel pipe is a kind of carbon steel pipe with high performance and high precision. The welded round steel pipe can be used in various fields, such as agricultural machinery, aerial work machinery, petrochemical machinery and hosting machiner and so on. The pipe has the characteristics of high precision, homogenizing wall thickness, uniform. The pipe size can be customized.





Features:


High performance:

yield strength 1000MPa ,length 16M,high strength,wear resistance, easy welding,impact resistance.

High precision:

OD,thickness,Rcorner,straightness,Perpendicularity can be controlled. Acid pickling,shot blasting, galvanization can provide.

Special:

Special material, special specification,special use,special requirement.

Special-shaped section:

According to the requirements of customers, we can produce all kinds of non-standard models with high speed and low cost.

Advantages of cold bending welded steel pipe:

1. High-strength:

Grain refinement and crystallinity increase during processing. 2. High-toughness: Plastic deformation occurs in the process of processing, so that the organization is refined and homogenized

3. Corrosion resistance

4.energy conservation and emission reduction: Cold rolling does not require high temperature, so it reduces energy consumption and smoke emissions, which is conducive to energy saving, emission reduction and environmental protection.

5.Material utilization:

The shape and size of materials can be better controlled during manufacturing, so raw materials can be used more efficiently and waste generated less.
