Stainless Steel Pipe Types: Seamless, Welded, and ERW

In the realm of stainless steel pipe, the choices can be overwhelming. Each type, whether seamless, welded, or ERW (Electric Resistance Welded), offers distinct advantages and disadvantages. The selection of the right stainless steel pipe type hinges on project requirements, and as seasoned stainless steel suppliers, we are here to guide you through this crucial decision-making process.

Seamless Stainless Steel Pipe

Seamless stainless steel pipe are manufactured without any welding or joints, resulting in a continuous, unbroken structure. This unique production process grants seamless pipes several advantages:


High Strength: Seamless pipes boast superior strength, making them suitable for high-pressure applications in industries such as oil and gas.

Corrosion Resistance: Seamless pipes exhibit exceptional resistance to corrosion, ensuring longevity and reliability, even in harsh environments.

Smooth Interior: The absence of weld seams on the interior surface minimizes turbulence in fluid flow, reducing friction and allowing for efficient transportation of liquids and gases.

Aesthetics: Seamless pipes offer a sleek appearance with a clean, uninterrupted surface, making them an excellent choice for architectural applications.


Cost: Seamless stainless steel pipe tend to be more expensive than their welded counterparts due to the complex manufacturing process.

Limited Size Range: Seamless pipes are typically available in smaller size ranges compared to welded pipes.

Welded Stainless Steel Pipe

Welded stainless steel pipe are constructed by joining sections of steel together through various welding processes, such as TIG (Tungsten Inert Gas) or MIG (Metal Inert Gas). This method results in pipes with distinct qualities:


Cost-Efficiency: Welded pipes are generally more cost-effective to produce, making them a budget-friendly option for many applications.

Versatility: Welded pipes come in a wide range of sizes and shapes, accommodating various project requirements.

Durability: When done correctly, welding creates strong bonds, ensuring the structural integrity of the pipe.

Customization: Welded pipes can be customized to specific lengths and diameters, offering flexibility in design.


Corrosion Vulnerability: Welded areas are susceptible to corrosion, which may require additional protection measures, such as coatings or regular maintenance.

Reduced Interior Smoothness: The presence of weld seams on the interior surface can cause increased friction and turbulence in fluid flow.

ERW (Electric Resistance Welded) Stainless Steel Pipe

ERW stainless steel pipe are a type of welded pipe manufactured using electrical resistance welding. This method involves passing an electric current through the edges of the steel to create a weld seam:


Cost-Effective: ERW pipes are cost-effective to produce and offer a reasonable balance between cost and performance.

Good Strength: These pipes provide satisfactory strength for many applications, including those in construction and transportation.

Availability: ERW pipes are readily available in a variety of sizes and specifications, making them suitable for diverse projects.

Reliable Welds: ERW welding produces dependable welds with good structural integrity.


Corrosion Susceptibility: Like other welded pipes, ERW pipes are vulnerable to corrosion, necessitating proper maintenance.

Limited Use in High-Pressure Applications: ERW pipes may not be ideal for applications with extremely high pressures or temperatures, where seamless pipes are often preferred.

Choosing the Right Stainless Steel Pipe

The choice between seamless, welded, or ERW stainless steel pipe should be informed by project requirements. Here are some insights to help you decide:

Seamless pipes are ideal for high-pressure and corrosive environments, where strength and longevity are paramount. Consider them for critical applications in industries like oil and gas.

Welded pipes offer cost-efficiency and versatility, making them suitable for a wide range of applications, including structural support and general fluid transport.

ERW pipes strike a balance between cost and performance and are suitable for many applications, such as construction and transportation.

Stainless Steel Pipe Manufacturing Process

At HXSCO, as dedicated stainless steel suppliers, our commitment to delivering high-quality stainless steel pipe is unwavering. Understanding the intricate manufacturing process behind these pipes is crucial to appreciate the level of precision and craftsmanship that goes into every product. Join us on a journey through the step-by-step stainless steel pipe manufacturing process, where quality control measures are our guiding light.

Selection of Raw Materials

The journey of crafting a stainless steel pipe begins with the careful selection of raw materials. High-quality stainless steel, typically in the form of coils or sheets, is chosen. The grade and composition of the steel are critical factors, as they determine the pipe’s resistance to corrosion, temperature tolerance, and overall durability. At Stainless steel suppliers HXSCO, we source our stainless steel from trusted suppliers to ensure the highest quality from the outset.

Forming the Pipe

The chosen stainless steel material is then subjected to a forming process, where it is shaped into a tubular form. There are several methods for this, including:

Hot Extrusion: Involves heating the steel and forcing it through a die to create the desired shape.
Cold Pilgering: A cold-working process that reduces the diameter and increases the wall thickness of the pipe.
Welded Pipes: For welded pipes, the steel is rolled into a cylindrical shape and welded along the seam.

Heat Treatment

To enhance the mechanical properties of the stainless steel, it undergoes a heat treatment process. This involves heating the pipe to specific temperatures and then cooling it rapidly. The heat treatment helps improve the pipe’s strength, hardness, and resistance to corrosion, ensuring it can withstand the rigors of its intended application.

Welding (For Welded Pipes)

In the case of welded stainless steel pipe, the longitudinal seam is created through welding. Various methods like TIG (Tungsten Inert Gas), MIG (Metal Inert Gas), or laser welding are employed to achieve a strong and reliable weld. Stringent quality control measures are applied during this phase to ensure the weld meets industry standards.

Cold Sizing and Straightening

The pipe is then passed through a series of cold sizing and straightening processes to achieve the desired dimensions and remove any irregularities. This step is critical for ensuring the pipe’s uniformity and integrity.

Quality Control Measures

Quality control is a hallmark of our stainless steel pipe manufacturing process. At every stage, our dedicated team of experts meticulously inspects and tests the pipes to ensure they meet or exceed industry standards. Key quality control measures include:

Dimensional Checks: Precise measurements are taken to verify the pipe’s diameter, wall thickness, and length, ensuring they conform to specifications.

Visual Inspection: Highly trained inspectors visually assess the surface quality, looking for any imperfections, scratches, or surface irregularities.

Non-Destructive Testing (NDT): Techniques like ultrasonic testing and radiography are employed to detect internal defects, ensuring the integrity of the pipe.

Chemical Analysis: Comprehensive chemical analysis is conducted to verify that the stainless steel composition meets the specified grade and standards.

Mechanical Testing: Tensile and hardness tests are performed to assess the pipe’s mechanical properties and ensure they meet or exceed requirements.

Final Finishing

The stainless steel pipe undergo a final finishing process, which may include pickling, passivation, polishing, or coating, depending on the intended application. This step enhances the pipe’s surface finish and corrosion resistance.
