Clamps
segmented-screw-clamp
This quick-release pressure vessel clamp system is the most practical and widely used means of positively securing flanges on pressure vessels in processing plants. The clamps replace conventional swing bolts and typically provide substantial saving over stud bolts on any vessel or processing equipment requiring even occasional opening. A wide range of sizes and types are available, including special versions with limited swing, downward release, reversing swing, etc… The segmented screw clamp can be modified to fit your processing needs. SAVE TIME AND MONEY
  • REDUCE LABOR TIME IN HALF or less as compared with standard nut and bolt
  • NO DRILLED FLANGES – Closing force acts near vessel wall
  • LESS Material (Narrower & shallower flange section)
  • LESS Preparatory Work
  • LESS Machining (drilling, rolling, etc…)
  • FEWER closing screw clamps than standard nut and bolt
  • QUICKER RELEASE with fewer turns of each nut
  • SAFER – Eliminates dangers created by missing nuts and bolts

Typical Applications
  • Reactor Vessels
  • Pressure Vessels
  • Vacuum Vessels
  • Pressurized Filter Housings Mix Vessels
  • Centrifuges
  • Manways

This unique screw clamping system is utilized for securing tank covers, manways, port holes, and flange openings without the necessity to drill and tap bolt holes into the flange surfaces, saving material and time in building and assembling these flanges. The clamps are available with ASME code certification.
