Electro Polished Pipes & Tubes, also known as EP pipes, are manufactured through a special process that includes ultra-precision polishing treatment, achieving an inner surface roughness of Ra ≤ 0.5μm. These pipes are characterized by their excellent corrosion resistance, high inner surface smoothness, cleanliness, and anti-adhesion properties, which allow them to maintain good performance under harsh conditions such as high temperatures and pressures.

The production process of EP pipes involves a combination of electrolytic polishing technology and special passivation treatment. This innovative process generates minimal chemical pollution, and it replaces traditional chemical cleaning with ultrasonic cleaning, significantly reducing environmental impact and aligning with modern eco-friendly concepts and regulatory policies.

Stainless steel EP pipes are high-quality, high-performance stainless steel tubes with broad market application prospects. They are widely used in pipeline transportation systems in industries such as pharmaceuticals, biological vaccines, and precision instruments. Additionally, they are extensively applied in semiconductor instruments, pressure vessels, rare gas/ultra-pure gas transmission, chip manufacturing, hydrogen production, nuclear power, photovoltaics, machinery, and other sectors.
