ANSI/ASME B16.5 Carbon Steel Blind Flanges Class 900LB BLRF for Industrial Applications

Introduction:

Shaanxi Peter International Trade Co., Ltd. is a well-established company with extensive experience in the production of ANSI B16.5 Class 900 Blind Flanges. We are dedicated to providing a wide range of flanges that cater to the diverse needs of our customers.

 

Our ANSI B16.5 Class 900 Blind Flanges are crafted with precision and adhere to stringent quality standards. We recognize the crucial role these flanges play in sealing pipe systems and ensuring their integrity. To guarantee durability and long-lasting performance, we exclusively use high-quality materials such as carbon steel, stainless steel, or alloy steel.

 

Our ANSI B16.5 Class 900 Blind Flanges comply with the ANSI B16.5 standard, meeting industry requirements for dimensions, tolerances, materials, and testing. We prioritize quality assurance and proudly guarantee the exceptional performance and reliability of our blind flanges, even in demanding applications.

 

 

Description of ANSI B16.5 Blind Flanges:

Blind flanges conforming to ANSI B16.5 are available in two styles, Raised Face (RF) and Flat Face (FF). Unlike other flange types, they don't have a center bore or opening and are instead used to seal the end of a piping system, preventing flow rather than creating a connection point for liquid, gas, or air. Blind flanges serve various purposes such as testing pipe pressure, providing an access point in a piping system, temporarily sealing a piping system for modification or repair, or terminating a piping system permanently.

 

One of the primary benefits of using blind flanges is that they can be bolted rather than welded in place. This makes maintenance and inspection of the pipe system easier and allows for future expansion. To create a tight seal, a gasket is paired with the blind flange. The gasket fills the space between the flange faces, preventing any liquid or gas from leaking out.
