FAQs of Orifice Flanges:

Q: How are orifice flanges used for flow measurement in pipelines?

A: Orifice flanges are designed with a corresponding orifice plate and accessories to precisely measure fluid flow within a pipeline. By creating a pressure differential across the plate, they enable highly accurate readings of flow rate and help maintain system efficiency.

Q: What testing processes do orifice flanges undergo before delivery?

A: All flanges are subject to ultrasonic, hydrostatic, and X-ray testing based on customer requirements. These tests ensure structural integrity, leak-proof performance, and compliance with international standards such as ASME B16.36 and PED.

Q: When should I choose a Raised Face (RF), Flat Face (FF), or Ring Type Joint (RTJ) gasket face?

A: The selection depends on your pipelines pressure, temperature, and sealing needs. RF is common for general service, FF is used with flat-faced mating flanges, and RTJ suits high-pressure, high-temperature applications requiring superior sealing.

Q: Where can these orifice flanges be applied?

A: Orifice flanges are utilized in refineries, chemical plants, water treatment facilities, and several industrial sectors across India and globally. Their material diversity and compliance with various standards make them suitable for complex and critical systems.

Q: What accessories are included with orifice flanges?

A: Each package can include an orifice plate, jacking screws for plate removal, pressure tapping points, and a complete bolting kit. These accessories facilitate smooth assembly and precise pressure measurement during operation.

Q: How does the anti-corrosive surface finish benefit the product?

A: Anti-corrosive finishessuch as anti-rust oil or paintprotect the flanges against oxidation and harsh environments, extending service life and reducing maintenance frequency in challenging process conditions.

Q: What are the advantages of sourcing orifice flanges from certified and compliant manufacturers?

A: Certified flanges (NACE MR0175, PED, IBR) ensure top quality, reliability, and safety. This guarantees compliance with rigorous industry regulations, assures material traceability, and supports successful audits and inspections.
