What is carbon steel welded pipe, and how is it different from other types of pipes?
Carbon steel welded pipe refers to a type of pipe made from carbon steel that is specifically manufactured through the welding process. Carbon steel is widely used because of its strength, durability, and cost-effectiveness. Welding involves fusing two pieces of metal using heat and pressure, creating a strong and continuous joint. Carbon Steel Welded Pipes have distinctive characteristics compared to other types of pipes, such as seamless or ductile iron pipes.
Unlike seamless pipes manufactured without welded seams, carbon steel welded pipes have welded joints along their length. This welding process introduces additional strength to the pipe, making it suitable for various applications. Carbon steel welded pipes are generally more affordable and readily available than ductile iron pipes, making them a popular choice in many industries.

What are the main applications and industries commonly use carbon steel welded pipes?
Carbon steel welded pipes find extensive applications across various industries. One primary sector that commonly utilises carbon steel welded pipes is the oil and gas industry. Due to their durability and high-pressure resistance, these pipes are widely employed for transporting oil, gas, and other fluids over long distances. Carbon steel welded pipes are extensively used in the construction industry for structural purposes, such as the fabrication of buildings, bridges, and infrastructure.
They provide robustness and stability in supporting heavy loads and ensuring the integrity of structures. Carbon steel welded pipes are commonly used in water and wastewater treatment to convey water, sewage, and other fluids. They are also used in manufacturing to transport raw materials, chemicals, and process fluids. Carbon steel welded pipes' versatility, strength, and affordability make them suitable for various applications and industries.

Electric Resistance Welding (ERW) Process
Pipe is created using the Electric Resistance Welding (ERW)
process by cold-forming a flat steel sheet into a cylindrical
shape. The steel is then heated to a degree at which the edges
of the steel cylinder are pressed together to establish a bond
without the use of welding filler material.
Several Electric Resistance Welding (ERW) processes are
available for pipe production. The two main types of ERW are:
. High Frequency Welding
. Rotary Contact Wheel Welding.
High Frequency Welding
In high frequency induction welding, a work coil is placed in front of the weld spot and acts as a conduit for the weld current to reach the material. Work coil does not come into contact with pipe. Through the magnetic fields that surround the pipe, an electrical current is induced into the pipe's substance. When changing pipe size, high frequency induction welding avoids contact marks and requires less setup time.
Rotary Contact Wheel Welding
The electrical current is passed through a contact wheel at the weld spot in rotary contact wheel welding. A portion of the forge pressure required for the welding process is also applied by the contact wheel. AC, DC, and square wave are the three primary types of rotary contact wheel welders. Electrical current is transferred in all three power supplies by brush assemblies that interact with slip rings attached to a revolving shaft that holds the contact wheels. The current is sent to the strip edges through these contact wheels.
Submerged Arc Welding (SAW) Process
A constantly fed bare wire electrode and the workpiece form an
arc during the submerged arc welding (SAW) process. To produce
protective gases, slag, and to add alloying components to the
weld pool, the procedure requires a flux. Using a shielding gas
is not necessary. Excess flux is recycled via a hopper as the
arc advances along the joint line. After welding, any remaining
layers of fused slag are simple to remove. The arc is generally
invisible during welding because the flux layer totally covers
it, and heat loss is also very minimal. In contrast to the
manual metal arc's 25% thermal efficiency, this one can reach
60%.
There are two types of Submerged Arc Welding (SAW) processes:
. Longitudinal Submerged Arc Welding (LSAW) Process
. Spiral Submerged Arc Welding (SSAW) Process
