Alloy 601 & Alloy 602ca Manufacturer and Exporter

Alloy 601 & Alloy 602ca Tube inserts or ferrules are inserted into the end of a heat exchanger tube to provide a specific function such as protection.

We manufacturing and exporting a wide range of boiler tube ferrule, condenser tube inserts, heat exchanger ferrule tube inserts, ferrules, APH sleeve tube &  Tapered Tube Plugs.

The purpose of the tube insert is to be sacrificial to the effects of inlet-end erosion or corrosion. They are also used to transfer extremely high heat past the tube sheet to the exchanger tubes. A metal tube insert is more durable in these environments. Ceramics perform well when the temperatures are extremely high. However, ceramics can be subject to breaking. Unity Tube can provide many ferrules or tube inserts in a variety of materials and sizes. Tube sheet type heat exchangers used in chemical reactors, particularly those exposed to reducing, nitridizing and/or carburizing environments. Such means include the use of certain ferrules within the heat exchange tubes and/or weld types used in construction of these

Heat exchangers.Heat exchanger sleeving, a money-saving technology generally associated with the electric power industry, is drawing increasing interest from engineers in the chemical process industries (CPI), as well. Sleeving consists of expanding thin tubes (sleeves) into the tubes of a heat exchanger. The expanding process produces a residual, interfacial fit pressure between the outside surface of the sleeve and the inside surface of the tube. The sleeves may be short, for instance about 6 to 16 in., or may extend for the full straight length of the tubes. Typical sleeve thicknesses are 0.01 to 0.03 in., depending upon material of construction and thickness of the original tubes. In addition to the expansion step, sometimes the inner end of the sleeves is welded to the inside wall of the tube. In tubular heat transfer equipment in power plants, sleeving has long been used for one or more of these purposes.

• To reduce the prospect of inlet-end tube erosion (short sleeves for this purpose are also called ferrules, and their use is called ferruling)

• To restore tubes to service that had been plugged by plant personnel because of known perforations in discrete, identifiable locations.

• To restore tubes to service that had been plugged because their walls had become excessively thin.

• To bridge failures in discrete locations of tubes that are otherwise intact for example, if a tube has a circular crack just beyond the inner face of the tubesheet
Before applying sleeving to similar problems at CPI plants, it is useful to: be aware of the sleeving methods and equipment available, be able to determine how sleeves affect the heat transfer performance of heat exchangers, and be able to calculate the changes in pressure drop through the tubes.
