FAQ's of Stainless Steel Spectacle Flange 304 L:

Q: How are Stainless Steel Spectacle Flange 304L components typically used in piping systems?

A: These flanges are primarily installed between pipe sections to allow for visual inspection, flow control, or isolation of the pipeline. They can be applied in process industries, oil & gas facilities, and petrochemical systems where periodic maintenance or flow diversion is necessary.

Q: What benefits does the 304L stainless steel grade provide for spectacle flanges?

A: 304L stainless steel offers excellent corrosion resistance, high strength, and durability, making it ideal for harsh industrial environments. Its low carbon content minimizes the risk of carbide precipitation during welding, ensuring long-term, leak-proof service.

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

A: Select RF for higher pressure applications requiring enhanced sealing, FF for applications with flat gasket requirements, and RTJ for environments needing superior leak resistance under high pressure and temperature fluctuations.

Q: What is the process for manufacturing these spectacle flanges?

A: Manufacturing involves forging high-purity 304L stainless steel, followed by precision machining to ASME/ANSI standards. The flange is then finished using techniques such as pickling, sandblasting, or mirror polishing, and rigorously tested for hardness, dimensional accuracy, and surface quality.

Q: Where can these spectacle flanges be sourced and how are they packaged?

A: They are readily available throughout India via dealers, distributors, exporters, manufacturers, and other supply channels. Packaging is done in robust wooden boxes or cartons, ensuring safe delivery and ease of storage.

Q: What temperature and pressure ranges can these flanges withstand?

A: The Stainless Steel Spectacle Flange 304L operates efficiently within temperatures of -40C to 800C and pressure classes ranging from 150# to 2500#, adhering to ASME B16.5/B16.47 compliance.
