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.

When condenser tubes leak, water supplied for cooling is drawn by the condenser vacuum into the condensate. The impact level of this impurity will depend on the level of the cooling water that is in-leakage and the quality of the cooling water. System design and boiler water treatment are selected with consideration of minimizing damage from condenser tubes leak. For these reasons, these plugs are required to prevent further damage and improve production efficiency. These include Ex-three expanding plug, The Pin plug, Fiber plugs, High confidence plugs, Tube-sheet plug and Ex-f expanding plug.

Ex-3 fitting is tried to withstand an extensive variety of weight, temperature and vibration states reaching up to 150 pounds for every square crawl. It highlights an extensive external washer that allows tubes to fit with sheets and not permit the attachment to be maneuvered into the vacuum of the unit. It is accessible in metal, bronze, stainless steel and titanium. It is additionally simple to rapidly introduce and oversee and has a larger than usual washer permitting this attachment to be put flush with the tube sheet and thus not be sucked into the tube 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.

The next type of condenser type is the high confidence which is suitable enough to be taken to use when it is a must that the leaking tubes be plugged out of the heated condenser tubes so that they can be used. High confidence plugs features include re-usability, durability and innovative gripping and sealing design.

The sheet attachment gives a remarkable full-length seal at great temperatures and disconnects sheet openings from the framework, permitting proceeded with utilization of the unit without real update. The two piece configuration is a snap to introduce utilizing a hammer and can therefore be welded to the spot. It is accessible in bronze and steel.

Last on the list is Ex- F expanding plug. It has a dual-action design that makes it an excellent choice for applications where plug spillage may be a concern. Its unique features include dual action sealing and gripping design, its durable and easy to install.
