As a method for recapturing productivity of a warmth exchanger or chiller, attachments are introduced to take cracked tubes out of administration. This takes after the general guideline which is a vessel should be re-tubed after at least 10 percent of the available tubes have been completely sealed. The condenser tube plugs should be stopped at both closures of the weight.

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 never-ending fixing of condenser tubes and sheets crevices, the one bit of diminished blueprint of the Type 1 pin Plug is made to match different tubes sizes. The one-piece arrangement is a snap to present using a mallet. Furthermore, can be welded into spot. For this kind of fitting, Special materials and sizes can be solely made. This sort of tube gives a basic response for immutable halting for tubes or sheet crevices.

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.

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 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.
