Soft Joint Flange

High quality soft joint flange is offered by China manufacturer SN Valve. Soft joint flange usually consists of a pair of flanges, a soft joint (e.g. made of rubber, plastic or other elastic materials) and a number of bolts and nuts. The soft joint sits between the two flanges and acts as a seal and cushion. This type of flange connection through the bolts and nuts to the two flanges closely clamped together, and use the elastic deformation of the soft joint to compensate for the piping system displacement, vibration and temperature changes and other factors caused by the stress.

Product Description

Features and Advantages

HIGH SEALING PERFORMANCE: Due to the excellent elasticity and sealing properties of soft joints, Soft joint flange is able to provide higher sealing performance and prevent medium leakage.
Good flexibility: Soft joint flange can absorb displacement and vibration in piping system, thus reducing stress and damage to piping system.
Strong adaptability: Soft joint flange is suitable for various media and temperature conditions, and can meet the needs of different industrial fields.
Easy installation: Compared with welded flanges, Soft joint flange is relatively easy to install and does not require complicated welding operations.

Application Scenario

Soft joint flange is widely used in piping systems in petroleum, chemical, shipbuilding, pharmaceutical, metallurgical and other industries. Especially in the working environment that needs to withstand large displacement, vibration and temperature change, Soft joint flange is favored for its good flexibility and sealing performance.

Selection and Installation

Selection of material: When selecting Soft joint flange, it is necessary to consider the temperature, pressure and corrosiveness of the medium as well as the displacement and vibration of the piping system. Ensure that the selected material can adapt to the requirements of the working environment.
Determine the size: According to the size and pressure rating of the piping system, select the appropriate size and type of Soft joint flange.
Correct installation: When installing Soft joint flange, you need to follow the installation instructions or drawings. Make sure the gap between flanges is even and the bolts and nuts are tightened with proper torque. At the same time, pay attention to protect the Soft joint flange from damage.

Maintenance and Inspection

Periodic inspection: Periodic inspection of Soft joint flange includes checking whether the soft joint is aging, damaged or deformed. If any problem is found, it should be replaced or repaired in time.
Cleaning and maintenance: Clean Soft joint flange and its connecting parts regularly, remove oil, dust and other impurities on the surface. Keep good connection status and sealing performance.
Pay attention to the use environment: Avoid exposing Soft joint flange to high temperature, high pressure or corrosive environment for a long time, so as not to reduce its service life and performance.
