ASME B16.48 Spectacle Blind Flange Raised Face Class150-2500

Product Data

Product Introduction

ASME B16.48 spectacle blind flange Raised Face is a special type of flange commonly used in piping systems to allow control of the flow direction and pressure of fluids. This type of flange is typically used in applications that require periodic maintenance, overhaul or cleaning of piping systems, or where fluid leakage or mixing needs to be prevented.

Here are some key features and information about the ASME B16.48 spectacle blind flange Raised Face:

Standard:

ASME B16.48 specifies the size, design, materials and connection requirements for Spectacle Blind Flange Raised Face to ensure its performance and interchangeability.

Sizes and Pressure Ratings:

ASME B16.48 specifies the requirements for Spectacle Blind Flange Raised Face in different sizes and pressure ratings to meet the needs of various piping systems. Common sizes are 1/2″-24″ DN15-DN1200, and the pressure level range is Class150-Class2500.

Construction:

ASME B16.48 Spectacle Blind Flange Raised Face is typically made of metal, with common materials including carbon steel, stainless steel, and alloy steel. Raised Face means that the flange has a raised face on the sealing surface to provide additional sealing performance.

Sealing:

Raised Face protrusions on the flange provide additional sealing properties, ensuring a reduced risk of leakage at the flange connection.

Function:

One of the main functions of the Spectacle Blind Flange Raised Face is to allow pipes to be blocked when needed. It consists of two circular blind plates, one blind plate can rotate to close the pipe, and the other blind plate can rotate to open the pipe. This feature makes it a device that can control flow direction and pressure.

Application:

This type of flange is typically used in applications that require periodic inspection, cleaning or maintenance of piping systems. For example, sight blind flanges are often used in chemical, oil and gas, power plants, and other industrial areas.

Installtion and operation:

The Spectacle Blind Flange Raised Face requires regular inspection and operation to ensure its proper operation. The operator can rotate the blind plate to control the flow direction and pressure of the fluid.

In summary, the ASME B16.48 Spectacle Blind Flange Raised Face is a special flange used in piping systems that can be used to control the flow direction and pressure of fluids, especially for applications that require regular maintenance and overhaul. Its Raised Face design provides a reliable seal to reduce the risk of leaks. The choice of such flange usually depends on the needs of the specific application and the requirements of the piping system.
