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.

CNC stands for Computer Numeric Control and CNC machining is a process, which is mainly used in the manufacturing sector. Different machine tools can be controlled using computers. A number of tools, which include routers, grinders, mills, and lathes can be controlled by a CNC machine. A wide variety of machined parts can be produced by CNC machining technology. BDE Inc. is a leading provider of CNC machining services and machined parts and components. 

While each type of manufacturing process has its advantages and disadvantages, this article focuses on the CNC machining process, outlining the basics of the process, and the various components and tooling of the CNC machine (sometimes incorrectly known as a C and C machine). Additionally, this article explores various mechanical CNC machining operations and presents alternatives to the CNC machining process.

In these types of anodes, the anode material is not in direct contact with the surface to be protected, and there is a gap (hence the name stand-off). The insert is generally a tubular one which can be welded or bolted to the surface.)

The benefit of a stand-off design is that it is a more compact design, and the anode material is better utilized in a stand-off design. This is quantified by a parameter called ‘anode utilization factor’. This is the fraction of the anode material which is actually utilized over the lifetime of the anode. For flush anodes, this is around 80%, while for stand-off anodes it is 85 to 90%. Thus, stand-off anodes are better utilized over their lifetime.

Further, in case of flush anodes, due to constant contact between the anode material and the surface, the surface may suffer from embrittlement caused by deposition of ions from the anode material to the cathode (the protected surface).

That said, stand-off anodes protrude from the surface on which they are installed. When used on external hull of a vessel, these affect the streamlined shape of the vessel, and lead to increased drag and higher powering requirements. In comparison, flush anodes are closer and more compliant to the vessel’s geometric shape and have lower effect on resistance. Thus, flush anodes are usually preferred on outer hull due to their low drag properties.

Both Flush mounted and slender stand-off anodes are further classified into Short and Long, depending on their ratio of length to width. The length affects the resistivity of the anode and thus its current capacity.

Positive terminal of an electrolytic cell at which corrosion occurs, a piece of metal fixed to steel to provide cathodic protection it means Cathodic protection (CP) can be defined as e.g. “electrochemical protection by decreasing the corrosion potential to a level at which the corrosion rate of the metal is significantly reduced” (ISO 8044) or “a technique to reduce corrosion of a metal surface by making that surface the cathode of an electrochemical cell” (NACE RP0176). The process of suppressing the corrosion potential to a more negative potential is referred to as cathodic polarization. Cathodic protection, stops and delays the progress of corrosion on both new and older metal structures.
This means: Prolonging your steel structures life expectancy and durability. Thereby decreasing maintenance costs. Steel structures in soil, water and concrete are effectively protected by cathodic protection.. In simple terms, the anode would be the driving source of protection.
