ANSI/ASME B16.5 Carbon Steel Blind Flanges Class 400LB BLRF for Industrial Applications

Introduction:

Thank you for your interest in Shaanxi Peter International Trade Co., Ltd. We are a well-established and respected firm with extensive experience in the industry, and we are pleased to introduce our comprehensive range of ANSI B16.5 Class 400 Blind Flanges.

 

Our blind flanges are designed and manufactured using high-quality materials such as carbon steel or stainless steel, ensuring durability and corrosion resistance. They feature a solid, flat disc that covers the end of the pipeline, providing a reliable seal.

 

One of the key features of our ANSI B16.5 Class 400 Blind Flanges is their pressure rating. With a Class 400 pressure rating, they are suitable for applications with working pressures up to 400 pounds per square inch (psi). This rating ensures their reliability and safety in various high-pressure environments.

 

We offer a wide range of sizes to accommodate different piping system requirements, ranging from smaller diameters to larger sizes. Additionally, our blind flanges are versatile and can be used in various industries, including oil and gas, petrochemical, power generation, and more.

 

Our ANSI B16.5 Class 400 Blind Flanges comply with the ANSI B16.5 standard, ensuring that they meet industry requirements for dimensions, tolerances, materials, and testing. We are committed to quality assurance and guarantee the performance and reliability of our blind flanges in demanding applications.

 

 

Description of Carbon Steel Blind Flanges:

Carbon steel blind flanges are solid pieces used to block the end of a pipe system or valve. They are commonly used to shut off a piping system or to terminate it. These flanges are designed without a bore, making them ideal for applications where the end of the line needs to be closed off. Carbon steel blind flanges are typically used in high-pressure or high-temperature applications due to the strength and durability of carbon steel material. They are available in various sizes and pressure ratings to accommodate different piping system requirements. Additionally, these flanges are often used in conjunction with other equipment such as valves and fittings to provide a secure and sealed termination point for the piping system.

 

Carbon Steel Blind flanges are relatively simple in construction compared to other flange types, requiring less mechanical machining and being heavier due to the absence of a bore. Although these flanges are typically provided as blanks to accommodate slip on flanges and weld neck flanges, we also offer custom machining options. Common modifications include center machining for NPT threads and custom bore sizes for use as slip on flanges without a hub.
