Copes-Vulcan Severe Service Valves and Desuperheaters

Copes-Vulcan engineers severe-service control valves and steam conditioning units for power plants. SD and D-100 globe valves utilize RAVEN anti-cavitation and HUSH low-noise trims. VO-II variable orifice desuperheaters and DSCV valves control steam temperature.

  • Severe-duty globe control valves SD and D-100 series
  • Multi-stage RAVEN anti-cavitation & HUSH trims
  • VO-II variable orifice desuperheaters & DSCV/PRDS
  • Replacement valve cages, plugs, seats & actuators

M&J Valve Pipeline Gate and Surge Relief Valves

M&J Valve manufactures API 6D pipeline isolation and surge relief valves for oil and gas transmission. The range includes M-303 and C-303 thru-conduit slab gate valves and DAN-EX expanding gate valves. Danflo surge relief valves protect pipelines from pressure spikes.

  • API 6D thru-conduit slab gate valves M-303 & C-303
  • DAN-EX expanding gate valves with DBB isolation
  • Danflo axial surge relief & 4-way diverter valves
  • Replacement gates, seat rings, stems & packing kits

Plenty Screw Pumps and Industrial Filtration Systems

Plenty combines positive displacement pumps with Airpel, Dollinger, and Vokes filtration systems. Mirrlees TRIRO three-screw, TWINRO two-screw, and U2000 vane pumps transfer viscous oils and fuels. Basket strainers and coalescers clean liquids and gas streams.

  • Mirrlees TRIRO 3-screw & TWINRO 2-screw pumps
  • U2000 variable-flow & Magmo rotary vane pumps
  • Airpel strainers, Dollinger & Vokes gas coalescers
  • Screw sets, liners, rotor blades & filter elements

GD Engineering Bandlock 2 Closures and Pigging Systems

GD Engineering designs pipeline pigging access systems and pressure vessel closures to ASME VIII. Bandlock 2 quick-opening closures with conical locking rings operate across ANSI Class 150 to 2500 ratings. Hi-T Pigalert signallers detect pig passage reliably.

  • Bandlock 2 quick-opening closures (ASME VIII Div.1/2)
  • Sizes from 6" to 60", pressure classes ANSI 150–2500
  • Hi-T Pigalert signallers & MPL multi-pig launchers
  • Replacement lip seals, locking bands & bleed interlocks

S&N Pumps Offshore Submersible Seawater Pump Packages

S&N Pumps manufactures heavy-duty submersible pump packages for offshore platforms, FPSO vessels, and intakes. Seawater lift and firewater pumps use super duplex steel and nickel-aluminum bronze castings. Units integrate water-filled submersible electric motors.

  • Submersible seawater lift & cooling water pump units
  • Offshore firewater pump packages for rigs and FPSOs
  • Super duplex stainless steel, NAB & titanium metallurgy
  • Water-filled submersible motors, seals & cable glands

Selecting ClydeUnion, Plenty, and S&N Industrial Pumping Systems

The pumping portfolio of Celeros Flow Technology integrates ClydeUnion Pumps, Plenty Pumps, and S&N Pumps to serve upstream oil and gas, refining, nuclear island, and conventional power applications.

For high-pressure water injection, hydroprocessing, and boiler feed duties, engineers specify API 610 radially split barrel pumps (CUP-BB5 / legacy DB36), axially split multistage pumps (CUP-BB3 / DB34), and API 674 reciprocating plunger units.

For viscous lube oils, heavy fuel oils, and bitumen transfer, Plenty supplies Mirrlees TRIRO three-screw pumps, TWINRO two-screw pumps, and U2000 variable-flow rotary vane units.

Offshore platforms and FPSO vessels utilize S&N Pumps submersible seawater lift and firewater pump packages cast in super duplex stainless steel and nickel-aluminum bronze.

Copes-Vulcan Control Valves, M&J Pipeline Valves, and GD Bandlock Closures

For severe-service pressure letdown, anti-cavitation control, and steam conditioning, Copes-Vulcan provides SD and D-100 globe valves equipped with multi-stage RAVEN velocity-control trims and HUSH cages, alongside VO-II variable orifice desuperheaters and DSCV steam conditioning valves.

Crude and product transmission pipelines rely on M&J Valve API 6D thru-conduit slab gate valves (M-303, C-303), DAN-EX mechanical expanding gate valves with double block and bleed (DBB) integrity, and Danflo surge relief systems.

Pipeline pigging traps and Airpel/Dollinger filtration vessels integrate GD Engineering Bandlock 2 quick-opening closures and Hi-T Pigalert pig passage signallers.
