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.

Fiber plug can be installed for emergency or temporary plugging to the heat exchanger tubes and the condenser. They are able to increase in size when wet to completely cover the tubes. It does not cause damage to the tube sheets and can be used at high temperatures of 230 Fahrenheit and pressures of up to four hundred psi. It requires only a mallet for easy and quick installation 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 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.

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.
