The CC2F double flange dismantling joint can transmit the pressure thrust of the connected parts and compensate the installation error of the pipeline, and can not absorb the axial displacement. The CC2F double flange dismantling joint is mainly used for loose connection with the accessories such as pumps and valves. In the course of use, it is mainly different from the compensation joint and the limit compensation joint. Its compensation amount refers to the adjustment amount during the installation and disassembly process. Once all the nuts are tightened, it is rigidly connected and can transmit the shaft. Heart, thus protecting valves, pumps and other equipment.
large expansion and easy maintenance.
CC2F double flange dismantling joint : After being installed on the pipeline, it is limited according to the required telescopic expansion and contraction distance, and the nut is tightened. The elastic sealing ring relies on the inclination of the nut under the action of the nut gland, and is pressed against the outer ring of the pipe. Sealing and connecting function, mainly connected with the pipeline valve not only plays the role of pipeline compensation, but also facilitates the maintenance and replacement of the valve.
1 The installation is simple and convenient, which is beneficial to the disassembly and maintenance of the pump valve.
2 long service life and stable operation.
3 can reverse the axial thrust of the pipeline to the entire pipeline to avoid local compression.
CC2F double flange dismantling joints are suitable for conveying seawater, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, steam and granular powder with a temperature not higher than 250 degrees. medium.
It is mainly used to transfer the internal force of the pipeline to avoid damage caused by the products applied in the pipeline system due to excessive concentration of the force, so it is used in various types of pipeline systems.
The CC2F double flange dismantling joint is suitable for the pipeline connecting both sides and the flange. When installing, adjust the installation length of the two ends of the product and the flange, and evenly tighten the gland bolts in the opposite direction to make it a whole and have certain The amount of displacement is convenient for installation and maintenance, and is adjusted according to the size of the site. The axial thrust can be transmitted to the entire pipe during operation. The strength of the compensation joint body shall be able to withstand the pressure of 1.5 times the nominal pressure, and the pressure shall be kept for 5 minutes without leakage and obvious plastic deformation. The compensation joint sealing pair shall be able to withstand the pressure of 1.25 times the nominal pressure, and the pressure shall be kept for 5 minutes without leakage.

2.remove the joint parts
Carbon steel or stainless steel disassembly joints (compensation joints), nominally through ≤ 400mm, the limit of short pipe, short pipe flange cylinder should be used seamless steel pipe.
The carbon steel reinforcement for the compensation joint (disassembly joint) shall be hot-dip galvanized. The surface of the parts of the compensation joint (disassembly joint) shall be free from cracks, crusting, folding, delamination, etc., and shall not be scratched, grooved or collided. A significant depression formed.
