Most Reliable Condenser Tube Plugs

By Kenya England


As a means of regaining stability of a chiller or a heat exchanger, plugs are put in place to remove leaky tubes out of action. This follows the rule that is a it will need to be re-tubed after eleven percent of the tubes have been put in place.All the condenser tube plugs must be plugged at both ends.

Whenever there is a leakage in the condenser, cooling water is taken in by the condenser into the purity condensate.The degree of this impurity depends on the amount of the water-coolant supplied and it's quality. The system structure and high temperature treatment are taken into consideration with the intentions of of minimizing damage on condenser tubes. Plugs are therefore required to avoid further damage and increase production efficiency. Examples include Ex-3 Pin plug, Expanding plug, High confidence plugs, Fiber plugs, Tube sheet plug and Ex-F expanding plug.

The ex-three plug has been tested to withstand a variety of pressures, temperature and vibration conditions of up to one hundred and fifty pounds per square inch. It features a large outer washer that allows the tubes to fit with the sheet and not allow the plug to be pulled into the vacuum unit. It is available in brass, bronze, stainless steel and titanium. It is also easy to quickly install and manage and has an over-sized washer allowing this plug to be placed with the sheet and not be sucked into the tubes by unit vacuum.

For permanent plugging of condenser tubes and sheet holes, the one piece of tapered design of the Type 1 pin Plug is machined to match specific tubes sizes. The one-piece design is a snap to install using a mallet. And can be welded into place. For this type of plug, Special materials and sizes can be custom manufactured. This type of tube provides an easy solution to permanent plugging for tubes or tube sheet holes.

The Fiber type can be put in place in case of an emergency or temporarily to the high temperature exchanger and the condenser. These plugs are capable of expanding when cold to completely seal the tubes. They can not cause damage to sheets and can be utilized at temperatures of two-thirty Fahrenheit and pressures of up to four hundred psi. It is easy to set up and install since it only requires a mallet and can therefore be machined to fit specific tubes sizes.

High confidence plugs are suited for use when you have to plug off leaking tubes in condensers and heat exchangers since they are re usable. It's features include innovative gripping and sealing design, It can be removed and re used, it's durable and safe for use in coated or epoxied tube sheets.

The sheet plug provides an exceptional full-length seal at high temperatures and isolates sheet holes from the system, allowing continued use of the unit without major overhaul. The two piece design is a snap to install using a mallet and can even be welded into place. It is available in bronze, titanium and steel.

The extending attachment finishes the rundown. It has a two-activity outline which settles on it the best decision for particular applications where plug spillage may be of need. Its unmistakable components incorporate double activity fixing and grasping outline and simplicity of establishment.
