High Alloy Cold Extruded Outlets and Manifolds are used where process design conditions include High Temperature, High Pressure, and Highly Corrosive Atmospheres. Typical applications for the industry sectors for both grass roots and retrofit projects include:
  • Inlet distributors: Located at the top of the furnace, produced in high alloy material specifications
  • Cold Outlet Collectors: Located at the bottom of the furnace, produced in high alloy material specifications
  • Transfer Lines: For transferring process gases to the waste heat boiler
  • Fluid Catalytic Cracking Unit: Air Grids and other components with high alloy extrusion requirement


  • Quench Water Nozzle
  • Extruded Headers (inlet and outlet)
  • FEED Injection Nozzle 
  • High Temperature Thermowells
  • High Velocity Quench Tube Assemblies (Gas Oil Furnace)
  • Quench Tube Outlets
  • Inlet TLX "Y" Assemblies
  • Thermowells & Hangers
  • TW with Cast Alloy 6 Tapered Tip, Flanged TW's, Teardrop TW's, TW housing
  • Extruded Manifolds
  • Radiant Headers
  • TLX Legs
  • Heat Exchanger Ferrules 
  • Fitting Connections (Tees, Elbows, Crosses, & Spools) 
  • Crossover Transfer Lines 
  • Venturi Coil Inlets
