Male And Female Flange

ANSI/ASME B16.5, B 16.47 Male Female Pipe Flange Manufacturer

A male and female flange is a type of pipe flange that features two distinct surfaces designed to fit together. The male flange has a raised, protruding lip, while the female flange has a corresponding recessed area that fits over the raised lip of the male flange. This design allows the two flanges to lock into place securely, forming a strong and leak-resistant connection. These flanges adhere to international standards such as ASME, ISO, and DIN, ensuring that they meet the necessary dimensional, material, and pressure specifications for industrial use.

What sets Ample Alloys apart is its dedication to excellence. The company adheres to international standards like ASME, ANSI, and DIN, ensuring precision-engineered products that meet the highest benchmarks of quality.

Technical Expertise

Our knowledgeable team provides technical guidance and support to ensure you select the right flange for your application.

These flanges are commonly used in applications requiring high-pressure containment, including oil and gas, chemical processing, and power generation industries.

Male and female flanges have a unique sealing mechanism where the raised and recessed faces create a tight fit, unlike flat face or raised face flanges.

While the design offers a tight seal, gaskets are often used to enhance the sealing performance in high-pressure or high-temperature applications.
