ASME ANSI B16.5 Carbon Stainless Steel Blind Flange

Product Data

Product Introduction

Blind flange is an industrial flange connection used to close or cover unused flange connections on piping systems or equipment.

Dimensions and standards:

The dimensions and design of blind flanges usually follow international standards, such as ANSI/ASME B16.5 and DIN. Different standards specify different sizes of blind flanges to match flange connections on piping systems or equipment.

Pressure Rating:

The pressure rating of a blind flange usually varies based on the needs of the piping system or equipment. Different pressure levels correspond to different working pressure ranges, usually covering various conditions from low pressure to high pressure. The selection of pressure level should be determined based on specific application requirements.

Material:

Blind flanges are usually made of metal materials, such as carbon steel, stainless steel, aluminum, etc., to meet the requirements of high temperature, high pressure and corrosive environments. Material selection depends on the fluid and operating conditions of the piping system.

Advantages and Disadvantages:

Advantage:

1.Safety: Blind flange is used to safely seal the flange connection to prevent fluid or gas leakage and ensure the safety of operators.
2.Flexibility: They allow pipe connections to be closed or opened when needed for maintenance, inspection or equipment replacement.
3.Anti-pollution: It can prevent external substances from entering the pipeline system and keep the inside of the pipeline clean.

Shortcoming:

1.Requires manual intervention: Installing and removing blind flanges often requires manual intervention, which can take time and effort.
2.Cost: Blind flanges and their installation and maintenance can add to the overall cost.

Blind flanges are usually used in the following situations:

1.Safe closure: When piping systems or equipment need to be repaired, cleaned, inspected or maintained, blind flanges can be used to securely close flange connections to prevent fluid or gas leakage, ensuring operator safety.

2.Prevent contamination: In some industrial or chemical processes, it is sometimes necessary to temporarily seal the flange to prevent external substances from contaminating the fluid or gas inside the piping system.

3.Temporary closure: Blind flanges can also be used to temporarily close specific connections of pipes or equipment to allow for repairs, replacement of parts, or other work.

Before using a blind flange, you need to ensure that you select the correct size and type of blind flange to match the specifications of the pipe or equipment, and that it needs to be installed in strict accordance with relevant safety standards and procedures. In addition, blind flanges can also be used with sealing gaskets to ensure good sealing performance.

In summary, a blind flange is an important industrial component used to close pipe or equipment connections for safe maintenance, operation and contamination prevention.
