Injection lances (or fittings) are generally used within dosing systems as a means of introducing chemical into main pipeline streams.
CSS can offer a wide range of both withdrawable and fixed fittings.
The lances can incorporate N.R.V’s to prevent backflow.
In order to select and quote for a suitable injection fitting we require
- Dosage rate, pressure, and composition
- Main line size, pressure and preferred tapping size and type (or existing tapping details)
- Type of injection fitting required, insertion distance, if NRV required, and preferred dosage connection.
