Shand & Jurs 95220 Clamping Manway Cover

For storage tank engineers, digester operators, and large-vessel maintenance teams, the Shand & Jurs 95220 Clamping Manway Cover provides secure, oversized access for large-diameter storage tank manways and digester covers while maintaining vapor-tight and watertight closure between entries.

Unlike conventional bolted manway covers on large openings that require removing a full bolt pattern to enter and often develop gasket drift across inspection cycles, the 95220 uses a hinged lightweight dome combined with a threaded clamping handle and flexible elastomer seal to create a reliable mechanical closure that opens rapidly by releasing the clamping hardware.

A self-locking foot pedal and safety locking pins secure the cover against unintended closure during maintenance or entry. The corrosion-resistant base and cover and flexible elastomer seal support predictable performance in petroleum, chemical, and industrial storage environments.

Available in 30″, 36″, 42″, 48″, 54″, and 60″ sizes with flat-face drilled flanges to ANSI, API, or DIN standards, the 95220 suits vertical atmospheric storage tanks, digester covers, and floating roof access where frequent, rapid large-diameter entry is required.

Features

Threaded Clamping Handle

Provides controlled compression of the seal for gas-tight and watertight closure, removing the bolt-by-bolt uncertainty of conventional large-diameter manway covers.

Hinged Lightweight Dome

Offers unobstructed large-diameter access for routine inspection and service, opening rapidly by releasing the clamping hardware rather than removing a full bolt pattern.

Flexible Elastomer Seal

Maintains consistent compression to limit fugitive leakage in low-pressure environments across repeated open-close cycles through the service life of the cover.

Multiple Large Diameters

Sizes from 30″ to 60″ cover a range of common tank and digester openings, matching existing manway patterns without custom nozzle work.

Self-Locking Foot Pedal

Prevents accidental closure during maintenance or entry, protecting personnel working inside the tank or digester during scheduled service events.

Flat-Face Drilled Flanges

Supports ANSI, API, or DIN bolt patterns for installation flexibility across regional tank-construction standards without requiring custom flange adaptation.

Applications

  • Storage Tank Access: Large-diameter personnel entry on vertical atmospheric storage tanks where rapid hinged access and dependable resealing between entries are both required.
  • Large Manway Maintenance: Routine inspection and service on large openings where removing and reinstalling a full bolt pattern would extend outage time and introduce gasket variability.
  • Product Sampling: Larger-diameter sampling access where specialized sampling apparatus or inspection tooling requires a full manway rather than a standard gauge hatch.
  • Digester Access: Entry on anaerobic digesters and biogas vessels where vapor-tight sealing limits fugitive methane release and protects personnel during scheduled maintenance.
  • Floating Roof Inspection: Roof-top entry for seal and leg inspection where the cover must reseal reliably after each entry to restore normal roof breathing behavior.
  • Terminal Tank Farm Cover Access: Large tank covers at petroleum terminals where frequent scheduled access and predictable low-pressure sealing must coexist across the tank's inspection cycle.

What distinguishes the 95220 from the 95210?

−

The 95220 is engineered for larger-diameter openings — 30″ through 60″ — and uses a hinged lightweight dome with a threaded clamping handle, self-locking foot pedal, and safety locking pins. The 95210 covers 16″ through 48″ with a similar threaded clamping approach. Selection depends on the tank manway diameter and whether the additional safety hardware of the 95220 is required for the entry procedure.

How does the safety hardware protect personnel during entry?

+

A self-locking foot pedal and safety locking pins secure the cover in the open position, preventing unintended closure while personnel are working at or inside the tank or digester. This addresses one of the principal operational risks on large-diameter manway access.

What working pressure can the 95220 seal against?

+

Maximum working pressure is approximately 1 PSIG nominal, matching the low-pressure service typical of vertical atmospheric storage tanks and anaerobic digesters. The threaded clamping compression and elastomer seal maintain vapor-tight and watertight closure across this range.

Which sizes and flange patterns are available?

+

Nominal sizes are 30″, 36″, 42″, 48″, 54″, and 60″ with flat-face drilled flanges to ANSI, API, or DIN standards. An undrilled flange version is available for projects requiring custom field drilling where standard patterns do not match the existing tank nozzle.

Is an ATEX configuration available?

+

Yes. ATEX and CE configurations are available for hazardous area installations, alongside protective coating options for severe environments and non-ferrous clamping hardware (brass, bronze, stainless) where spark resistance is required in flammable service.

How is the 95220 ordered?

+

Part numbers follow the format 95220-[A][B]-[C][D]-[E], where A is cover size (30″–60″), B is seal material (NBR/CR), C is clamping hardware material, D is flange drilling standard (ANSI/API/DIN), and E is an option code for coatings or certifications. Cognesense applications support can assist with the full configuration.

Summary

With over a century of tank-safety heritage inside Cognesense, the Shand & Jurs 95220 Clamping Manway Cover is chosen when large-diameter manways on storage tanks and digesters require frequent, rapid access without sacrificing vapor-tight and watertight closure. Its hinged lightweight dome, threaded clamping handle, self-locking foot pedal, and flexible elastomer seal deliver dependable performance across 30″ to 60″ openings. For petroleum, chemical, and industrial storage, the 95220 is trusted wherever you need to measure, monitor, and protect what matters most.
