Frequently Asked Questions

A plate flange, also known as a flat flange or slip-on plate flange, is a type of flange that consists of a flat, circular plate with bolt holes around the perimeter. It is used to connect pipes, valves, or other equipment to a pipeline system. Plate flanges are designed to provide a strong, secure connection while allowing for easy alignment and installation.

Plate flanges are available in a wide range of sizes to match different pipe diameters and flange standards. Standard sizes typically range from 1/2 inch to 24 inches or more. Custom sizes and specifications can also be manufactured to meet specific needs.

Plate flanges are installed by aligning the flange with the pipe or equipment to be connected. The flange is then bolted into place using bolts and a gasket to create a leak-proof seal. Proper alignment and tightening are essential to ensure a secure connection.

Yes, we offer custom manufacturing solutions for plate flanges to meet specific requirements. Please contact us with your detailed specifications, and we will work with you to produce flanges tailored to your needs.

The lead time for plate flanges depends on the complexity and volume of the order. After reviewing your specifications, we will provide an estimated lead time. We are committed to delivering all projects on schedule while maintaining the highest quality standards.

Yes, plate flanges can be used for both liquid and gas applications, provided they are made from appropriate materials and installed correctly to handle the specific conditions of the system, including pressure and temperature.

Plate flanges are made from various materials, including carbon steel, stainless steel, alloy steel, and other metals. The choice of material depends on the application’s requirements, such as the type of fluid or gas, temperature, pressure, and environmental conditions.

Plate flanges are used in various industries, including oil and gas, petrochemical, water treatment, and construction. They are commonly employed for connecting pipes, valves, and other components to a pipeline system, providing a secure and stable connection.

Plate flanges are manufactured to comply with various industry standards, such as ASME B16.5, ASME B16.47, and API standards. These standards define the dimensions, tolerances, and material requirements to ensure compatibility and reliability in piping systems.

Plate flanges offer several advantages, including:

  • Ease of installation: Provides a simple and efficient connection method.
  • Alignment flexibility: Allows for easy alignment with pipes or equipment.
  • Versatility: Suitable for a wide range of applications and pipe sizes.
  • High strength and durability: Made from robust materials to handle high-pressure and temperature conditions.
