Product Overview
In food, beverage, and pharmaceutical processing, hygienic access to tanks and vessels is essential for inspection, cleaning, and maintenance. Our Food & Pharma Grade Round Hygienic Manway is specifically designed as a non-pressure sanitary access solution, providing safe, reliable entry while maintaining strict hygiene standards.
Manufactured from high-quality AISI 304 or AISI 316L stainless steel, this round manway features a smooth, crevice-free construction that minimizes contamination risks. The internal surface finish of Ra 0.5–0.8 μm ensures easy cleaning and effective CIP procedures, while the externally polished or matte-finished surface delivers both durability and a professional appearance. When closed, the hygienic gasket and hand-wheel tightening system create a secure seal suitable for low-pressure and atmospheric applications.
Designed for daily industrial use, the outward-opening cover allows convenient access to tank interiors for routine inspection, cleaning, and maintenance. Its robust yet simple structure makes it a dependable choice for food and pharmaceutical facilities where hygiene, reliability, and ease of operation are critical.
