A Sanitary Pressure Manway is a hygienic-grade access port designed for pressurized vessels in regulated industries. Key attributes include:
Material: AISI 304/316L stainless steel with electropolished surfaces (Ra ≤ 0.5μm) for contamination resistance
Pressure Rating: Typically 0-5 bar (some models up to 10 bar)
Sealing: Uses clamp (tri-clamp) or bolt mechanisms with EPDM/silicone gaskets for airtight closure
Shapes
Round: Common sizes DN200-DN800 (standard for dairy/pharma tanks)
Oval/Rectangular: E.g., 430×330mm, used in space-constrained installations
Opening Direction: Inward/outward options for different tank configurations
Food & Beverage: Milk tanks, brewing systems (CIP/SIP compatible)
Pharma: Bioreactors meeting GMP/ASME BPE standards
Chemical: Corrosion-resistant models for reactors
