1. Definition & Core Features

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


2. Design Variants

  • 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


3. Industry Applications

  • Food & Beverage‌: Milk tanks, brewing systems (CIP/SIP compatible)‌

  • Pharma‌: Bioreactors meeting GMP/ASME BPE standards‌

  • Chemical‌: Corrosion-resistant models for reactors‌
