Quick Release Pressure Vessel Clamps

Industrial processing plants frequently open and reseal pressure vessels, reactors, and filter housings for cleaning, inspection, and product changeovers. The fastening system holding those flanges together has a direct effect on downtime, safety, and long-term maintenance costs.

At Jaygo, we offer pressure vessel clamps specifically for this repeated-access demand, giving plant engineers, project engineers, and production managers a faster, code-compliant alternative to bolted flange connections. Here, we cover how our quick-release pressure clamps work, why they outperform conventional bolting, and how to spec the right configuration for your vessel.

What Is a Pressure Vessel Clamp?

A pressure vessel clamp, also called a segmented screw clamp, replaces the ring of individual bolts that traditionally holds two vessel flanges together. Curved clamp segments wrap around the joint and use a fastener mechanism to draw the flanges into a tight, uniform seal, which eliminates the need for drilled flange holes. This segmented design allows operators to open and close vessel flanges without having to remove every bolt, nut, and washer.

Why Quick Release Clamps Outperform Conventional Bolted Flanges

Standard nut-and-bolt closures require drilling a ring of holes through the vessel flange, and each hole becomes a point where stress concentrates under pressure. Our clamps eliminate that risk by closing around the flange face instead of passing through it, applying closing force near the vessel wall and allowing the flange itself to be machined or fabricated with a smaller diameter and/or thickness while still holding the same closing strength. That reduction in material lowers fabrication costs for new vessel builds.

On the maintenance side, plant crews typically cut labor time in half or more compared to a standard bolted closure. A single clamp action replaces the sequential tightening of an entire bolt circle every time the vessel needs to open. Using quick release clamps also eliminates the safety risks associated with missing nuts and bolts.

ASME Section VIII and PED Compliance

Every clamp we manufacture is designed to meet the latest PED code or ASME Section VIII requirements, the code governing design, fabrication, inspection, and testing for vessels operating above 15 psig. Because our clamps satisfy these safety requirements, specifying our clamps won’t create a compliance gap during your next inspection or policy review.

Compatible Vessel Types and Applications

Our pressure vessel clamps support quick access across a wide range of processing equipment, including, but not limited to:

  • Reactor vessels (regular and glass-lined). Frequent maintenance operations benefit from fast, repeatable resealing.
  • Pressure and vacuum vessels. Maintain a reliable seal under both positive and negative pressure conditions.
  • Pressurized filter housings. Speed up filter media changeouts without compromising the pressure boundary.
  • Mixing vessels and Nutsche filters. Support the frequent opening required for batch processing and cake discharge.
  • Centrifuges. Withstanding the vibration and cycling common to centrifuge operation.
  • Manways. Provide quick personnel access for inspection and cleaning.

Fastener Options: Material Specifications & Coating Options

We offer our clamps with a range of fasteners and finishes so you can match the clamp to your process environment and budget:

  • Fastener styles. Hex head nut, wing nut, and cap nut.
  • Fastener materials. B7 alloy steel for standard-duty applications, Type A4 stainless steel (Mat. No. 1.4571, 316Ti equivalent) for corrosion resistance, and Type B8M stainless steel (ASTM A193-B8M, 316Ti equivalent) for higher-strength stainless requirements.
  • Coating options. Zinc plating, Vecalit plating, electropolishing, and pickling and passivating.

Our team can help you match fastener material and coating to your product’s temperature, chemical exposure, and washdown requirements.
