They can be efficiently welded using commonly used welding methods, making them a practical choice for numerous construction and manufacturing projects. Stainless steel 309/309S welded pipes offer high strength and durability, capable of withstanding mechanical stresses and pressure variations. Their exceptional temperature resistance, corrosion resistance, weldability, and strength make stainless steel 309/309S welded pipes a preferred choice for applications requiring reliable performance in challenging conditions.

How does stainless steel 309/309S differ from other types of stainless steel?
Stainless steel 309 differs from other types of stainless steel in several ways, primarily in composition and performance characteristics. While stainless steel is known for its corrosion resistance, 309 offers enhanced resistance to high temperatures and thermal cycling. It contains more chromium and nickel than other stainless steel grades, providing excellent oxidation resistance and high-temperature strength.

Stainless steel 309S differs from other types of stainless steel in several notable aspects. It is an austenitic stainless steel alloy with a higher percentage of chromium and nickel than many other stainless steel grades. This increased chromium and nickel content gives 309S stainless steel enhanced resistance to corrosion and oxidation in high-temperature environments. One key differentiating factor of 309S is its low carbon content, making it more resistant to sensitization and subsequent intergranular corrosion. This property makes 309S stainless steel suitable for applications involving continuous exposure to elevated temperatures, such as furnace components, boiler tubes, and heat exchangers.

Stainless Steel 309 Welded Pipe Manufacturing Process

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
