Description of JIS B2220 Slip On Flanges:
JIS B2220 Slip On Flanges are a type of flange specified in the Japanese Industrial Standard (JIS) B2220. These flanges are designed to be slipped over the end of a pipe or fitting and then welded in place to create a secure and leak-tight connection.
The JIS B2220 Slip On Flanges have a flat face (FF) sealing surface, which allows for easy alignment during installation. They are commonly used in applications where ease of assembly and disassembly is required, as they can be easily slipped on and off the pipe or fitting.
These flanges are available in various sizes and pressure ratings, ranging from 10A to 1500A, and pressure ratings of 5K, 10K, 16K, 20K, 30K, 40K, or 63K. The material of construction for JIS B2220 Slip On Flanges can be carbon steel, stainless steel, alloy steel, or other materials as per the customer's requirements.
When constructing a new pipe system or replacing an existing one, JIS B2220 Carbon Steel and Stainless Steel Slip On Flanges can be used to create a seal between two pipes. These fittings are particularly suitable for low-pressure applications as they require less attention and are easier to install compared to weld neck flanges.
JIS B2220 Slip on flanges come in various sizes and styles, commonly made of carbon steel, stainless steel or alloy steel. They may feature a raised face or flat face, offering flexibility in selection based on your specific requirements.
The size of the flange is determined by the diameter of the pipe it is intended to connect. If you are uncertain about the dimensions, it is advisable to seek guidance from a professional to ensure a proper fit. JIS B2220 Slip on flanges are designed to accommodate a wide range of pipe sizes.
