Product description

JIS (Japanese Industrial Standards) is a series of industrial standards developed and published by Japan, covering a variety of different areas of product and technical specifications. JIS daily standard flange is a flange connection system developed under the JIS standard framework for connecting pipes, valves, equipment, etc.

JIS daily standard flanges are commonly used in industrial fields, especially in fluid transmission systems such as liquids and gases. These flanged connection systems allow different components such as pipes, valves, equipment, etc. to be connected together to enable fluid transmission and control. Flange connections usually involve the following main components:

1. Flange (Flange) : Flange is a flat round or square metal plate with some holes in the edge for bolting. The shape of the flange and the number of holes vary according to the requirements of the standard and application.

2. ** Flange Gasket: ** Flange gasket is located between flanges and is used to fill the gap between flanges to ensure the tightness of the connection. It is usually made of rubber, metal and other materials.

3. Bolts and Nuts: Bolts and nuts are used to connect the flange together to ensure the fastness and tightness of the connection by proper fastening force.

JIS daily standard flanges are available in different types and sizes to suit different application scenarios. They are classified into different pressure levels and connections to ensure the required tightness and reliability under different operating conditions. The classification of JIS flanges is usually based on the shape of the flange, the number of holes and the size.

In general, JIS daily standard flanges are a common connection method used in industrial piping systems, through standardized design and specifications, to ensure stable connection and fluid transmission in different application fields.

The JIS B2220 Slip-on Welding Flange is a fundamental and widely adopted component within industrial piping systems that conform to Japanese Industrial Standards. This type of flange is designed to be slipped over the pipe end and then welded both internally and externally, creating a robust connection. Its popularity stems from a balance of practical installation benefits, reliable performance, and economic efficiency. Engineers and project managers often select the JIS B2220 Slip-on Welding Flange for a variety of applications, from waterworks and plant utilities to general industrial service, due to its standardized dimensions and proven design principles.

A primary advantage of the JIS B2220 Slip-on Welding Flange is its relative ease of installation compared to other flange types. Since it does not require precise pipe end threading or complex machining for a weld neck, the initial fitting and alignment process is generally more straightforward. This characteristic can lead to reduced labor time and associated costs during assembly. The design allows for simpler alignment of bolt holes before the final welding, which is a significant practical benefit on the job site. However, it is crucial to follow proper welding procedures to ensure the integrity of the connection made with a JIS B2220 Slip-on Welding Flange.

From a cost-effectiveness perspective, this flange type often presents an economical choice. The manufacturing process for a JIS B2220 Slip-on Welding Flange typically requires less material than a comparable weld neck flange, as it lacks a long, tapered hub. This material efficiency can translate into lower initial unit costs, especially in projects with a large number of connections. For systems operating at moderate pressures and temperatures, the JIS B2220 Slip-on Welding Flange provides a reliable sealing solution without the need for the more robust—and more expensive—designs required for extreme service conditions.

In terms of mechanical performance, when properly installed, this flange offers dependable service. The double-weld configuration provides sufficient strength for many standard applications. The inherent reliability of the JIS B2220 Slip-on Welding Flange is backed by the comprehensive JIS standard, which specifies exacting requirements for materials, dimensions, pressure-temperature ratings, and testing. This standardization ensures interchangeability from different manufacturers and guarantees that the flange will perform as expected within its rated parameters, contributing to system safety and predictability.
