Selection and Applications of Dry Disconnect Couplings to Prevent Leakages

Dry disconnects are the fittings that ensure enhanced leak-free fluid handling in oil and fuel industry processes. They have a wide range of applications in various industries where there is no scope for accidental leakages into the environment and must conform to regulatory requirements.

In various industry verticals, dry disconnect or dry break couplings are used for ensuring safe and economical transfer of liquids or liquified gases into railcars or tanker trucks. They are widely used in petroleum, pharmaceutical, and chemical industries. With their self-sealing designs, these fittings guarantee the highest level of precision and safety during operations. You can buy them in varied seal sizes and materials to suit almost any type of application. These fittings are specifically suitable for applications that involve toxic, flammable, hazardous, or corrosive contents.

Selecting the Right Type of Dry Disconnect Fittings:
It can be daunting to find an appropriate type of dry disconnect couplings suited to your specific applications. You need to find the best type depending on your individual needs. You can buy Mann Tek couplings integrated with the best features and applications for maintaining accuracy and eliminating leakages during fluid transfers. Here are a few factors that you must consider:

●Acceptable Spillage:
Depending on the environment and applications, spillage allowed can vary up to a great extent. Therefore, it is necessary to consider the acceptable level of spillage when selecting the dry break couplings.

●Type of Valve:
The valves in a coupling can largely affect their flow rate. Hence, you should take precaution and choose the best among options like ball, butterfly, or poppet couplings.

●Operability:
The ease of operation is essential to maintain precision during transfer of fluids. In this regard, the position of connection in a coupling can affect their operability. So, you should consider this factor when looking to buy Mann Tek Couplings.

●Safe and Secure Connection:
Any accidental disconnection when handling hazardous fluids can cause serious injuries to the operators or environment. Hence, you should prefer couplings made by Mann Tek as they are fitted with a mechanical interlock system. At the same time, it should be capable of preventing cross contamination. There are couplings with sensors to avoid accidental connections made to a wrong hose line.

●The Dimensions and Weight:
An operator’s efficiency and safety also depend on these two factors. The weight of the coupling should be bearable since the hose needs to be frequently used. The size should match the intermediate bulk container in these couplings.

How To Use Mann Tek Dry Couplings to Avoid Leakages?

These couplings facilitate the safe transfer and dry break when disconnecting the fittings. Here are some important steps to be taken in this regard:

●It is essential to use the right type of equipment and accessories when using dry disconnects during fluid transfers. The face of the hose and tank units should be clean and dry to prevent spills during disconnections.

●Operate the couplings safely by pushing the hose into the tank and turn the large handle on the hose unit. The rollers in the hose unit will pass through the slots present in the tank unit to be locked behind the flange to ensure complete safety.

●Let the fluid transfer before releasing the coupling. The transfer will be completed when hose gets disconnected.

These are some important factors to know about selection and use of dry disconnect couplings in fluid transfer processes.
