A flexible connector is necessary because without one, there could be resulting problems in the pump due to too much loads from the pump nozzle. Nozzle loads can be a result of various factors such as thermal expansion and pipe misalignment. It can also be caused by leaking from the seal and problems in the bearing or coupling. Excessive nozzle loads can be prevented by buying the right flex connector for sale which will help correct the problems.
Choosing the correct connector with separate the pump vibration which can cause destruction since it can be amplified once it passes the piping system.
There are four basic kinds of flexible connectors that can be utilized on pipes. Common materials used in making the flex connectors are stainless steel, Teflon and rubber. The rubber connector can either be spool type or spherical type. The spherical is the most commonly used in pumps because of ease of installation. Spool types have rubber flanges with an incorporated metal backing rings for added support.
The braided hose connectors are a metal connector with flexible parts which is made of corrugated stainless steel. The fittings can either be stainless steel or carbon. It does not have the capacity to extend or compress thus will not be useful in case of thermal expansions. End fittings most widely used is male thread ends with small diameters and carbon steel flanges.
Metal bellows connectors operates the same way as rubber connectors due to its ability to compress. This is ideal in higher temperature settings where compression is necessary as a result of thermal expansion. The rods make sure that overextension does not occur while removing thrust loads.
PTFE connectors have a lot of benefits compared to metal because of its resistance against various chemicals. These are considered as expansion joints and bought together with rods to make sure overextension does not happen along with too much thrust loads.
When choosing the flex connector for sale, make sure to check the application where it is applicable as each has its own advantages and disadvantages. When in doubt, ask a professional for advice.
