Detachable Double-flange Power Delivery Joint
Detachable double flange delivery joint is a kind of pipeline connector used to connect two and more flanges, adopting detachable design, which can be installed and disassembled without using special tools. It is mainly used for transferring the pressure thrust of the connected parts and compensating the pipeline error, and at the same time, it can bear the axial displacement.
Overview
Material
The main materials of the joints include carbon steel and stainless steel.
Carbon steel: such as Q235 carbon steel, 20# seamless piping, 20G boiler piping, etc., suitable for general industrial piping.
Stainless steel: such as 304L and 316L, suitable for corrosive media or environments requiring higher corrosion resistance
Features
Structural features: compact structure, loose sleeve design.
Sealing performance: high temperature resistant, corrosion resistant sealing materials, sealing ring design.
Withstand pressure: high pressure tolerance.
Connection performance: double flange connection.
Installation and maintenance: detachable easy to install, adjustable installation length.
Scope of application: wide range of application, long life.
Technical requirements: specifications DN65mm-DN3200mm; test pressure (Mpa) 1.5-6.0Mpa; working pressure (Mpa) 0.6-2.5Mpa; medium temperature (℃) ≤ 80 ℃.
