Ring Type Joint Integral Orifice Plates Manufacturer in Mumbai India
Asre Engineering is a trusted Ring Type Joint (RTJ) Integral Orifice Plates manufacturer in Mumbai, India, supplying high‑accuracy differential pressure flow measurement solutions for oil & gas, petrochemical, power, and process industries. Our RTJ integral orifice plates combine orifice plate, orifice carrier, pressure taps, and RTJ flanges into a single compact assembly, ensuring leak‑free performance, repeatable accuracy, and easy installation.
Designed to comply with ASME, ISO 5167, and AGA standards, our RTJ orifice plates deliver stable flow measurement, reduced installation errors, and long service life in high‑pressure and high‑temperature applications.
In processes where suspended solids and debris are present, accurate flow measurement is often complemented by effective filtration and straining solutions. For upstream protection
of flow instruments and piping systems, Asre Engineering also recommends the use of industrial strainers and filtration equipment manufactured by our associate division. To explore high-quality Y strainers, basket strainers, and custom industrial strainers, visit our dedicated strainer manufacturing website at asrengineering.com, engineered to support reliable and clog-free process operations across industries.
Why Our Ring Type Joint – Integral Orifice Plates Stand Out
RTJ Flanged Construction – superior sealing for high‑pressure pipelines
Integral One‑Piece Design – eliminates misalignment and leakage risks
High Accuracy Flow Measurement – stable and repeatable DP readings
Custom Bore & Beta Ratio – engineered for your exact process conditions
Wide Material Options – carbon steel, stainless steel, alloy steel, duplex
Long Service Life – suitable for corrosive and high‑temperature fluids
Working Principle – How Our Ring Type Joint Integral Orifice Plates Work
A Ring Type Joint integral orifice plate measures flow by creating a controlled pressure drop across a precision‑machined orifice bore. As fluid passes through the bore:
Velocity increases at the restriction
Differential pressure is generated upstream and downstream
Pressure taps transmit DP to a DP transmitter
Flow rate is calculated using Bernoulli’s principle
The RTJ flange sealing ensures zero leakage, making it ideal for critical gas, steam, and liquid services.
