About the Daniel Simplex Single-Chamber Orifice Fittings
Save On Down-Time And Operational Costs
The Daniel® Simplex™ Single-Chamber Orifice Fittings are engineered for use on smaller line sizes. Their differential pressure measurement performance for gas and liquids in accordance with AGA 3, API 14.3 and OIML 5167 is superior. Operators can quickly perform plate inspections and changeouts with no need to remove the fitting from the line. This is because the unit-built construction, with the plate carrier permanently attached to the sealing bar, allows the sealing bar, carrier and plate to be removed as a unit. Spreading the flanges to change the plate is no longer necessary which means less downtime and lower costs, and the possibility of costly gas leakage or spillage of liquids is eliminated.

Features of the Daniel Simplex Single-Chamber Orifice Fittings
- The ability to remove the sealing bar, carrier and plate as a unit speeds up plate inspections and change-outs.
- No flange spreading is required for plate inspections and change-outs, eliminating liquid spillage or gas leakage.
- With no need to remove the fitting from the line when performing plate changes and maintenance, uptime is maximised.
- Maintenance time and cost is virtually eliminated with a simple fitting design with few parts.
- Concentricity in accordance with the latest AGA3/API 14.3 standards for consistently accurate measurement is ensured.
- Measurement at high-pressure wells and more with 3-in to 4-in fittings configurable up to 10,000 psig is achievable.
- Manufacturing in accordance with ASTM and ANSI flange connection specifications improves safety.
- Performance in accordance with ASME, with optional hydrostatic testing to 1.5 times operating pressure, is ensured.
