| Dri-Seal Tube Plugs | ||
The Dri-Seal range of products has been developed as a cost-effective means to enhance the longevity of both shell & tube and air-blast heat exchangers. Our product range currently comprises of:- Dri-Seal Jiffi-Plug - the safest and most convenient method of plugging failed heat exchanger tubes Dri-Seal Façade Tubeplate Protection System - for cost effective life extension of eroded or corroded heat exchanger tubeplates Dri-Seal Tube Insert - protect the ends of heat exchanger tubes from turbulence induced erosion  Dri-Seal jiffy–Plug The Dri-Seal Jiffy Plug is our latest patented development and offers a new and inexpensive way of sealing failed heat exchanger tubes safely and with the minimum of fuss. The Dri-Seal Jiffi-Plug has been developed be the safest and most cost effective form of plugging failed heat exchanger tubes. Produced from high performance plastics, the plugs can withstand temperatures up to 150° C and pressures up to 300psi, and are suitable for a wide range of heat transfer fluids and gases. The Problem One of the most common and irritating problems for the maintenance engineer is that of sealing failed heat exchanger tubes without causing damage to the surrounding tubes or tubeplate. Common methods of tube sealing include the use of tapered metallic plugs which are driven into the ends of the failed tubes. This process is not only unsafe and unreliable, but the plugs themselves can be extremely expensive due to their "made-to-order" nature. |  The Solution The Dri-Seal Jiffi-plug Tube Sealing System solves all of these problems in one easy step. The use of strong yet flexible polymer and copolymer materials ensures that even eroded/corroded tubes can be sealed without causing any damage or deformation to the tubes or tubeplate ligaments. The lack of complex mechanics within the sealing mechanism ensures that the Jiffi-Plug is both cost-effective and simple to fit. Materials The standard Dri-Seal Jiffi-Plug is produced from high performance Du Pont Hytrel and Acetal copolymer materials which have been selected for their temperature range and good chemical resistance. For information on the chemical resistance properties of the Dri-Seal Jiffi-Plug, please see our Chemical Resistance Guide. The main body of the plug is produced from DuPont Hytrel, a high performance elastomer chosen for it’s wide chemical resistance and property retention at elevated temperatures. The fixing pin is produced from Acetal copolymer, again chosen for it’s chemical resistance and property retention characteristics at elevated temperatures. Please see our Material Characteristics Guide for more information. Size Range The Dri-Seal range of Jiffi-Plugs currently covers most applications from 3/8" to 1" tube (outside diameter), with more being added all the time. Should the plug you require not be included in our plug availability list please contact us via our Contacts section for more information. Plug Sizing To ensure optimum performance, the plugs are specifically matched to the tube outside diameter and gauge (wall thickness). Please be sure of the figures for your application when enquiring about plugs. | Other product categories:- Heat Exchangers Finned Tubes and Cores Other products:- Condenser Ferrules Condenser Packing Ring Seals Fibre and Metallic Heat Exchanger and Condenser Tubes Leak Detection Tubes Tube Inserts Facade Tubeplate Protection U-Tubes and Coils |
