Their robust engineering guarantees long service life in critical environments.

FAQ's of Carbon Steel Ring Joint Flanges 65:

Q: How are Carbon Steel Ring Joint Flanges 65 installed in piping systems?

A: These flanges are typically installed using either welded or bolted connections at pipe ends, depending on system design and pressure requirements. Their ring joint or raised face connection offers reliable sealing, essential for high-pressure applications in oil, gas, and chemical industries.

Q: What benefits do the different coatings provide?

A: Coatings such as transparent oil, black paint, or yellow paint protect the flange surface against corrosion and wear. Rust-proof oil coating is standard, while painted finishes offer visual identification and extra protection in harsh environments, extending the service life of the flange.

Q: When should I choose a stock finish versus a spiral serrated face finish?

A: A stock finish is ideal for standard sealing when total face contact is needed, delivering excellent general performance. The spiral serrated finish, with its concentric grooves, is preferred in applications demanding superior gasket grip and improved sealing performance under challenging operating conditions.

Q: Where can these flanges be used within a plant or facility?

A: Carbon Steel Ring Joint Flanges 65 are primarily used at junctions requiring robust, leak-proof seals, such as in pressure vessel outlets, main pipelines, pumps, valves, or heat exchanger connections in refineries, power plants, marine setups, and petrochemical installations.

Q: What is the manufacturing process for these flanges?

A: The flanges are manufactured using a forging process to enhance strength and durability. After forging, they are machined to precise dimensions and finished with stock or spiral serrated face, followed by surface treatment and packing in wooden cases or pallets to ensure safety during transport.

Q: What are the key advantages of using these carbon steel flanges?

A: Key advantages include high tensile and yield strength, exceptional corrosion resistance, durability in temperature extremes, and compliance with international standards. Their versatility in end connections, finishes, and sizes meets a wide range of industrial requirements, making them a reliable choice for critical infrastructure.
