What is EWR pipe?
ERW (Electric Resistance Welded) pipes are essential in various industries due to their strength, versatility, and cost-effectiveness. Manufactured by rolling metal sheets and welding the edges together using an electric current, these pipes exhibit uniformity and durability. Widely used in structural applications, oil and gas, and water transportation, ERW pipes can be produced in various sizes and thicknesses, making them suitable for a range of pressures and diameters. Their smooth surface and consistent quality contribute to efficient flow and minimize maintenance.
Additionally, ERW pipes are often seen as a more sustainable option, as the production process can reduce waste and energy consumption compared to traditional methods.
Yuhong group provides high quality ERW pipe and export to various countries around the world, welcome to contact us for more details.

Why are 316L pipes widely used in waste water treatment plants?
1. Corrosion Resistance: 316L has excellent resistance to corrosion, especially in chloride-rich environments, which are common in sewage.
2. Durability: This material is strong and can withstand the mechanical stresses and abrasion that occur in sewage systems.
3. Sanitization: Its surface is easy to clean and sanitize, preventing bacterial growth and ensuring hygiene.
4. Temperature Resistance: 316L can handle a wide range of temperatures, making it suitable for various treatment processes.
5. Longevity: The long lifespan of 316L reduces the need for frequent replacements, making it cost-effective in the long run.
6. weldability: 316L is easy to weld, which allows for the construction of complex piping systems.
7. Low Maintenance: Due to its resistance to rust and staining, maintenance requirements are minimal.
