Cold drawn welded pipe is a type of steel pipe that is manufactured by welding together flat steel strips and then subjecting them to a cold drawing process. This method enhances the pipe’s mechanical properties and dimensional accuracy. Here’s an overview of the process and its features:

1. Material Preparation: Flat steel strips are cut to size from larger sheets.

2. Welding: The strips are rolled into a cylindrical shape and welded along the seam. This can be done using various welding techniques, including electric resistance welding.

3. Cold Drawing: After welding, the pipe undergoes a cold drawing process, where it is pulled through a die to reduce its diameter and increase its length. This step improves the pipe’s strength and surface finish.

4. Finishing: The pipes may go through additional treatments, such as annealing (to relieve stress), cleaning, and coating for corrosion resistance.

Rectangular welded pipe, also known as rectangular tube, is a type of hollow section made from flat steel sheets or strips that are rolled and welded into a rectangular shape. This type of pipe is widely used in various applications due to its structural strength and versatility.

Welded square pipe, also known as square tube or rectangular tube, is a type of hollow section made from flat steel sheets that are rolled and welded into a square or rectangular shape. This product is widely used in various construction and industrial applications due to its structural integrity and versatility.

Electro welded tubes, also known as electric resistance welded (ERW) tubes, are made from metal sheets that are rolled and welded together using an electric current. This process involves several key steps:

1. Material Preparation: Steel or other metal sheets are cut and prepared for rolling.

2. Forming: The sheets are rolled into a tubular shape.

3. Welding: An electric current is applied along the edges of the tube, which heats the metal and causes it to fuse together. This welding can be done using various methods, including high-frequency induction or contact welding.

4. Finishing: The welded tubes may undergo additional processes, such as cutting to length, cleaning, and surface treatment.

Electro welded tubes are widely used in various industries, including:

• Construction: For structural applications, scaffolding, and supports.
• Automotive: In the manufacturing of vehicle frames and components.
• Furniture: For making tubular furniture frames.
• Pipelines: In transporting fluids and gases.

• Cost-Effective: The production process is generally more economical than other methods like seamless tube manufacturing.
• Versatility: Can be produced in a wide range of sizes and shapes.
• Strength: Provides good mechanical properties suitable for many applications.

• Weld Integrity: The quality of the weld can affect the overall strength of the tube.
• Corrosion Resistance: May require additional coating or treatment.

Round welded steel pipe is a type of hollow steel tube that is formed by welding together flat steel sheets or strips into a circular cross-section. This type of pipe is widely used in various applications due to its strength, durability, and versatility.
