Product Description Stainless Steel Rectangular Square Round Oval Sanitary Pressure Tank Hatch Manway Manhole (JN-ML1001) A stainless steel sanitary square manhole is a clean-in-place (CIP) access port used in hygienic processing systems. It provides a secure and sanitary opening for inspection, cleaning, and maintenance in tanks or vessels. Made from high-quality stainless steel, it ensures corrosion resistance and durability. Its square shape allows for easy installation and efficient sealing.Working PrincipleThe stainless steel sanitary square manhole operates by providing a secure access point on tanks or vessels. First, the manhole cover is opened, allowing personnel to inspect or clean the interior. The gasket ensures a tight seal when closed, preventing contamination and leakage. Its robust stainless steel frame withstands pressure and corrosion. During operation, the manhole remains tightly sealed to maintain sanitary conditions. Size: 300×300mm, 400×400mm, 500×500mmMaterial: 304 or 316L stainless steelThickness: 3mm - 6mmSealing ring: Silicone or EPDMDesign pressure: 0.3 - 1.0 MPaWorking temperature: -20oC to 150oCSurface roughness: Ra ≤ 0.8μmOpening method: Quick clamping or bolt fixingConnection method: Flange connection or welding 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  Oval Non-pressure Manhole CoverOval Pressure Manhole CoverRound/ Rectangular Non-pressure Manhole CoverRound/Rectangular Pressure Manhole CoverDN500 Turnover Hopper ManholeSpecifications/ SizesNon-pressure sealing; sanitary sizes (DN range varies).Pressure-rated; exact rating varies.Atmospheric tanks; DN500-DN600 common.Pressure-rated; dairy-grade.DN500 turnover style.Working PrinciplesHinged/bolted closure for atmospheric tanks.Bolted closure withstands pressure.Hinged/turnover access.Pressure-tight bolted closure.Flip-open hopper manway.Key FeaturesSanitary finish, easy access, hygienic.Pressure seal, polished finish.Polished, crevice-free, CIP capable.Mirror polish, pressure-certified.Quick access, hygienic.Suitable ApplicationFood, beverage, dairy, pharma tanks.Pressurized vessels, steam/autoclave.Storage tanks, process vesselsPressurized food tanks, sterile storage.Hopper/discharge tanks.  Product Description Stainless steel sanitary fittings are widely used in high cleanliness industries and have the following significant feature:1. Square Frame Reinforcement for Tank Wall IntegrationReinforced square frame ensures stable mounting on flat tank surfaces, offering enhanced rigidity during pressure or vacuum cycles.2. Full Radiused Corners for Hygienic Flow TransitionsInternal corners are smoothly radiused to eliminate dead zones, improving clean-in-place (CIP) flow and minimizing bacterial accumulation.3. Heavy-Duty Locking System with Safety InterlockRobust swing bolts and optional safety latch provide secure sealing, reducing the risk of accidental opening during operation.4.Raised External Collar for Splash ProtectionThe elevated collar around the manhole opening helps deflect overflow, offering extra contamination prevention in washdown zones.5.Profiled Gasket Groove to Prevent Seal DisplacementGasket groove is precision-machined to lock the seal in place, maintaining uniform compression and minimizing leakage risk.6.Quick-Open Hinge Design with Position RetentionThe hinged cover remains open and stable during inspection, allowing hands-free tank access for operators during servicing.Product ParametersPackaging & ShippingFABFeature AdvantageBenefit1.Designed with a flat square frame for tank wall mounting, this manhole provides excellent surface compatibility and uniform contact. The flat profile enhances installation on rectangular or angular tank structures.2.Equipped with a precision-machined groove, the seal sits tightly without misalignment. This ensures consistent compression and improves long-term sealing reliability.3.Features a lift-assist hinge system allowing smooth opening. Operators can access the tank interior easily, especially during CIP or inspection.4.Includes an integrated safety locking system to prevent accidental release. The robust closure mechanism boosts operational safety in high-pressure environments.5.Constructed with polished internal surfaces and radius corners. It minimizes residue buildup, improving hygiene and cleaning efficiency.6.The cover plate is reinforced with support ribs. It prevents deformation during vacuum or pressure, maintaining long-term sealing integrity.1.Superior structural strength and sealing efficiency are achieved even under thermal cycling. This leads to minimal maintenance and less downtime in sanitary processing.2.Quick-open design with no-tool operation enhances operator efficiency. This design significantly reduces opening time, streamlining access.3.External splash guard collar design minimizes outside contamination. It adds a secondary barrier against splashes or CIP backflow.4.High compatibility with standard CIP/SIP systems and cleanroom operations. It integrates seamlessly into strict hygienic processes.5.Gasket groove prevents twisting or extrusion during pressure spikes. This feature extends gasket lifespan, reducing part replacement.6.Anti-drop hinge holds the lid in fixed open position. This reduces risk of operator injury, especially during overhead maintenance.1.By reducing microbial dead zones, this design improves compliance. It supports hygienic certifications like 3-A and EHEDG.2.Long-lasting performance cuts cost over time. Operators experience lower downtime, improving plant productivity.3.Clean design with no exposed threads or pits. This avoids cross-contamination, aligning with pharmaceutical-grade processing.4.Easy gasket replacement design speeds up maintenance. Downtime is minimized, optimizing production uptime.5.Compatible with various pressure ranges and applications. It adapts to different working conditions, boosting versatility.6.Offers clear operator handling safety during cleaning. The manhole cover stays secured, preventing unexpected lid drops.Product RecommendationsCompany Profile  Wenzhou Joneng Valves Co., Limited We  supply sanitary butterfly valve, sanitary flow diversion valve, sanitary CPM valve, sanitary regulating control valve, sanitary diaphragm valve, sanitary ball valve, sanitary sampling valve, sanitary safety valve, sanitary pressure reducing valveSanitary elbow, sanitary tee, sanitary reducers, sanitary unions, sanitary clamp, sanitary ferrule, sanitary pipe clamps, sanitary cleaning ball, sanitary sight glass, sanitary manway manhole cover, sanitary strainer, filters, and other sanitary pipe fittings... Welcome to check our other products.  About usJoNeng was established in July 2007, strategically situated in Wenzhou, China.
