Chemical Injectors

 

 Mist_Zoom2-1

U.S. Patent # 7,137,569

Application

KENCO Chemical Injectors are designed to inject and properly atomize corrosive chemicals into the turbulent stream of a process system pipeline. The KENCO Chemical Injector will minimize the possibility of corrosive chemical build-up on the walls of the pipeline. KENCO Chemical Injectors are recommended for use in pipelines with a flow-rate velocity of 40 feet per second (12.192 meters per second), or less.

KINJ & KINJM Injector Features

  • Unique aspirator tip design on injector disperses chemical evenly into process stream and away from pipe walls
  • Designed to be mounted in any orientation
  • Check Valve in injectors eliminates backflow
  • Injectors are ideal for high pressure applications up to 6000 psig
  • Standard materials available in 316 SS, CPVC & Hastelloy C 276
  • KINJ model comes standard with 1/2″ NPT chemical feed port
  • KINJM model comes standard with 1/8″ NPT or 1/4″ NPT chemical feed port
  • Ball check material is ceramic
  • Ball check spring material 316 S.S. & CPVC models is Inconel. Ball check spring material on Hastelloy models is Hastelloy C-276
  • “Cracking Pressure” to achieve flow through injector is less than 1 psig

KRINJ Injector Features

  • Unique aspirator tip design on injector disperses chemical evenly into process stream and away from pipe walls
  • Ball Valve assembly isolates pipeline from injector assembly when injection is not required
  • Compression seal holds the assembly from back pressure
  • Safety chain prevents the injector assembly from being completely withdrawn and protects against blowout
  • Retractable injectors are ideal for high pressure applications up to 150 psig
  • Standard ball valve assembly is brass. Also available in 316 SS, Alloy 20 & CPVC.
  • Standard retractable injector is CPVC. Also available in 316 SS & Hastelloy C 276.
  • Optional spring loaded check valve available in 316 SS, Hastelloy C 276 & CPVC. Check Valve available with body bleed.
  • Ball check material on all applicable models is ceramic
  • Ball check spring material on 316 S.S. & CPVC models is Inconel. Ball check spring material on Hastelloy models is Hastelloy C-276
  • “Cracking Pressure” to achieve flow through injector on all applicable models is less than 1 psig
