Product Description Stainless Steel Sanitary Round Outward Non Pressure Tank Manhole Cover with Full Sight Glass A sanitary stainless steel circular manhole is a hygienic access point designed for pressure or non-pressure tanks in clean process industries. It is commonly used in dairy, food, beverage, pharmaceutical, and biotech systems. Its purpose is to allow easy internal inspection, cleaning, and maintenance while ensuring a contamination-free seal. The smooth, crevice-free design supports hygienic compliance and CIP/SIP protocols.Working PrincipleThe sanitary stainless steel circular manhole operates by forming a sealed access point on tanks or vessels. When closed, its gasket is compressed by a clamp or swing-bolt mechanism to create a leak-proof, hygienic seal. To open, the operator loosens the handle or bolts, allowing the cover to be safely lifted for inspection or cleaning. During operation, it resists internal pressure or vacuum, maintaining system integrity and CIP compatibility without contamination.Type: Pressure / Non-pressureShape: RoundOpening Direction: Inward / OutwardDiameter: 200mm - 600mmSeal: Silicone / EPDM / PTFEFinish: Ra ≤ 0.8μm (internal)Mounting: Welded to tank wall or topWorking Pressure: 0 - 3 bar (varies by model)Temperature Range: -10°C to 120°C (depending on seal)Connection: With or without hinge, handle, or safety lock Quality guarantee of 3 yearsISO 9001, FDA, SGS approved materials7-10 days fast delivery on urgent requirements20 years' Rich exporting experience to make you easy and happy with custom work Product DescriptionStainless steel sanitary fittings are widely used in high cleanliness industries and have the following significant feature:1.Deep-Drawn or Precision-Welded ShellMinimizes weld seams for better structural integrity and easier internal cleaning, ideal for hygienic flow environments.2.Condensate-Draining Top HeadSloped or domed design prevents fluid accumulation and supports aseptic conditions in sterile or cleanroom applications.3.Fully Drainable Bottom GeometryHemispherical or conical bottom allows complete product discharge and reduces cleaning cycles in high-purity processes.4.Flush-Welded Sanitary NozzlesPorts are crevice-free, angled for flow, and designed for instrumentation and CIP, ensuring zero contamination points.5.Optional Thermal Control JacketDimple or shell jacket provides uniform heating or cooling while maintaining an easy-to-clean sanitary outer surface.6.Hygienic Support Base SystemPolished, adjustable legs with open clearance support floor wash-through and vibration-free operation in critical zones.Product ParametersPackaging & ShippingFABFeature AdvantageBenefit1.Round structure for uniform pressure distribution and hygienic sealing.2.Equipped with EPDM, silicone, or FKM gaskets for CIP/SIP compatibility.3.Quick-opening or bolt-clamped design for flexible operation.4.Internal surface polished to Ra ≤ 0.8μm, meeting high sanitary standards.5.Available in various pressure and vacuum ratings, suitable for multiple processes.6.Can be installed on tanks, vessels, or pipelines, both vertically and horizontally.1.Smooth interior finish reduces product residue and contamination risk.2.Tool-free access (for quick-opening models) accelerates inspection and cleaning.3.Compatible with 3-A, FDA, and EHEDG sanitary requirements.4.Corrosion-resistant construction ensures long-term durability.5.Pressure-resistant sealing enhances safety during operation.6.Allows customized dimensions and materials for specific process needs.1.Minimizes downtime during maintenance, improving overall efficiency.2.Ensures product purity, reducing batch rejection risks.3.Improves operator safety with secure locking and pressure relief options.4.Enhances regulatory compliance, easing audits and certifications.5.Reduces long-term operating costs due to durability and easy upkeep.6.Supports process integrity, protecting brand reputation and quality control.Product RecommendationsCompany Profile Wenzhou Joneng Valves Co., Limited Ezo stainless steel provides the following materials:Stainless steel butt welded tube pipe fittings ( butt welded elbow /bend, butt welded tee, butt welded reducers, stub ends, pipe capsStainless steel flanges(weld neck flange, slip on flange ,blind flange, plate flange ,lap joint flange, socket flange, threaded flange, square flange, marine flangestainless steel filter strainers ( Y filter, inline filter, L filter, housing filterStainless steel pumps ( stainless steel centrifugal pump, rotary lobe pump, CIP pump,screw pump, emulsion pump.Stainless steel man-ways ( Pressure type man-way, non pressure man-way, round man-way, rectangular man-wayStainless steel tanks ( storage tanks, mixing tanks,emulsion tanks, water tanksWelcome to check our other products.
