Features of ERW SS Pipe
ERW stainless steel pipe, often referred to as a “green pipe,” is highly advantageous for American readers due to its recyclability, durability, hygienic properties, and ease of maintenance. Our ERW stainless steel pipe is not only easily fabricated but also exhibits excellent resistance to corrosion, even in extreme temperatures. Moreover, it offers easy automation, high efficiency, malleability, and deformability.
Applications of ERW SS Pipes
Primarily, ERW stainless steel pipe finds wide applications in transporting oil, natural gas, and other liquid substances. It also serves numerous industries, including the textile industry, general engineering, hospitals, kitchen equipment, furniture, interior decoration, and paper & pulp manufacturing. Additionally, it is utilized in manufacturing automobile exhaust pipes, water pipelines, fencing, and scaffolding. ERW stainless steel pipe is an essential component for various sectors, such as sugar mills, dairies, breweries, and power plants.
Welding Techniques
To cater to your specific requirements, we offer a range of welding techniques for customizing your ERW stainless steel pipes. These include TIG (Tungsten Inert Gas), MIG (Metal Inert Gas), SMAW (Shielded Metal Arc Welding), PLASMA, SAW (Submerged Arc Welding), as well as FCAW (Flux-Cored Arc Welding).

ERW pipes are generally more cost-effective and suitable for non-critical applications, while EFW pipes are preferred for larger diameter and high-pressure applications where strength and corrosion resistance are crucial. It is important to consult with industry professionals or engineers to determine the most appropriate choice for your specific needs.
In summary, here are the different types of ERW pipes:
- Standard ERW Pipes: Regular ERW pipes complying with industry standards such as API 5L or ASTM A53.
- Line Pipes: Designed for oil, gas, and petrochemical transmission lines, capable of withstanding high pressures and harsh conditions.
- Structural Pipes: Used in construction and infrastructure projects for building frames, bridges, and support structures.
- Water Pipes: Specifically designed for transporting potable water in residential, commercial, and industrial settings.
- Galvanized ERW Pipes: ERW pipes with a zinc coating applied for enhanced corrosion resistance.
In summary, the main differences between ERW and DOM tubes lie in their manufacturing processes, surface finish, dimensional accuracy, and mechanical properties. ERW tubes are more commonly used and cost-effective for general applications, while DOM tubes offer superior precision and performance for specialized applications that demand tight tolerances and high-quality surface finish.
