Advantages of Welded Cold Formed Welded Structural Pipes

 In the construction and manufacturing sectors, the choice of welding materials and methods plays a vital role in the successful completion of any project. One such material that has become popular in recent years is cold-formed welded structural pipe. This innovative product offers several advantages over traditional seamless or welded pipes, especially spiral seam pipes.

 Cold formed welded structural pipe is manufactured through a cold-forming process, which involves bending and forming coils of steel into the desired shape. The result is a pipe that is both strong and durable, yet lightweight and easy to use. Additionally, the cold forming process ensures that the pipe maintains its structural integrity and dimensional accuracy, making it ideal for welding applications.

Mechanical Property

Chemical Composition

Hydrostatic Test

Each length of pipe shall be tested by the manufacturer to a hydrostatic pressure that will produce in the pipe wall a stress of not less than 60% of the specified minimum yield strength at room temperature. The pressure shall be determined by the following equation:
P=2St/D

Permissible Variations In Weights and Dimensions

Each length of pipe shall be weighed separately and its weight shall not vary more than 10% over or 5.5% under its theoretical weight, calculated using its length and its weight per unit length.
The outside diameter shall not vary more than ±1% from the specified nominal outside diameter.
Wall thickness at any point shall not more than 12.5% under the specified wall thickness.

Length

Single random lengths: 16 to 25ft(4.88 to 7.62m)
Double random lengths: over 25ft to 35ft(7.62 to 10.67m)
Uniform lengths: permissible variation ±1in

Ends

Pipe piles shall be furnished with plain ends, and the burrs at the ends shall be removed
When the pipe end specified to be bevel ends, the angle shall be 30 to 35 degree

 One of the main advantages of cold-formed welded structural pipe for welding is its ability to withstand high temperatures and pressures. Unlike traditional pipes, which are susceptible to corrosion and other forms of degradation, cold-formed pipes are engineered to withstand the rigors of welding and other industrial processes. This makes them ideal for use in a variety of applications from building construction to infrastructure projects.

 Another advantage of cold-formed welded structural pipe is its cost-effectiveness. The cold forming process can produce pipes in a variety of sizes and shapes, reducing the need for expensive casting and machining processes. This makes the product more affordable and as reliable as seamless or welded pipe. In addition, the lightweight nature of cold-formed pipe makes transportation and installation easier and more cost-effective, further increasing its appeal.

 Spiral seam tubes particularly benefit from the cold forming process. The inherent strength and flexibility of cold formed tubes make them ideal for creating durable and leak-proof spiral joints. This makes them an excellent choice for applications such as underground drainage systems, water lines and even agricultural irrigation systems. Additionally, the smooth surface of cold-formed pipes minimizes the risk of friction and wear, extending pipe life and reducing the need for maintenance and repairs.

 Overall, cold formed welded structural pipe offers a number of advantages that make it an excellent choice for welding applications, especially spiral seam pipe. Their strength, durability and cost-effectiveness make them an attractive choice for a wide range of industries, from construction to manufacturing. As the demand for high-quality, reliable materials continues to grow, cold-formed welded structural pipe will become an increasingly popular choice for welding applications.
