Hydrostatic Pressure Systems and Tools

  • Hydrostatic pressure systems provide a safe, fast, efficient means of testing and expansion of tubes
  • Expand tubes in fins for heat exchanger manufacturing
  • Repair boiler tubes by expanding (sleeving) a new tube into a damaged tube
  • Expand (swage) tubes into tube sheets

End Forming Systems and Tools

  • Hydraulic power packs produce raw forming strength in a compact package
  • End forming tools are used to expand, reduce, flare, bead, swage, or slit to exact specifications
  • Tool options include: hand-held, power pack mounted, or bench mounted

Hydro-Expansion Systems and Tools

  • Hydromechanical tube expansion systems and tools use water to force a ball through the tube to expand it
  • Hydro-expansion systems and tools use pressurized water taken past its yield point for tube expansion

High-Pressure Components and Accessories

  • Componets and Accessories include: accumulators, air bleed valves, air-driven pumps, check valves, control valves, dump valves, hoses and fittings, live swivels, pressure regulators, quick disconnects, and relief valves
  • Air-Driven Pumps have high-pressure flows from 0.5 gpm to 2 gpm (1.9 lpm to 7.6 lpm)
  • Patented Quick Disconnect Couplings rated at 20,000 psi, 30,000 psi, and 60,000 psi (1,379 bar, 2,068 bar, 4,137 bar)
