SS 304 ASTM A270 EP TUBE (MP/MP)

The ASTM A270 EP Stainless Steel Pipe is a high-purity, sanitary-grade tubing specifically manufactured for critical applications in the pharmaceutical, biotech, food, dairy, and beverage industries. These pipes undergo advanced electro-polishing (EP) to achieve an ultra-smooth, corrosion-resistant surface that minimizes bacterial adhesion and ensures maximum hygiene compliance.
