Manufacturer and exporters of Tube Inserts and Ferrules

Heat Exchanger Tube insert and ferrule are known as the same products, a metal, plastic or ceramic tube that is inserted into the end of a heat exchanger tube to provide a specific function. The purpose of a tube insert is to either be sacrificial to the effects of inlet-end erosion, corrosion, impingement to induce a fluid to fall on the ID of a tube in a falling film exchanger; or to transfer extremely high heat past the tube sheet to the exchanger tubes. Each of the above applications requires a specific style of design. At ASEC, we manufacture metal tube inserts for all applications, providing the necessary drawings required.

We manufacturer of Following Grade Ferrules / Tube Insert Sleeves.

  • Alloy 601 Ferrules / Tube Inserts Sleeves.
  • Alloy 602CA Ferrules / Tube Insert Sleeves.

Erosion-Corrosion (Impingement) Attack

Approximately 80% of all tube failures occur within the first couple inches of the heat exchanger tube inlet-end. This is referred to as inlet-end erosion. The solution to this problem is the use of a thin wall, metal tube insert expanded full length into the inlet-end of condensers and heat exchangers. Ideally, tube inserts are installed in units when originally manufactured. However, if they were not, tube inserts can compensate for any existing damage and protect the inlet from further damage. The tube insert is designed to ensure a smooth and gentle transition of the fluid down the tube insert to the condenser or heat exchanger tube. The tube insert is sacrificial and designed to absorb the tube damage that would normally occur to the condenser or heat exchanger tube. It is far less expensive to replace a 6 inch tube insert than a 20 or 40 or 60 foot condenser. or heat exchanger tube. The Navy uses tube inserts in its surface vessels. To quote advisory number 003-82, “Installation of inserts is recommended for all surface vessels to extend the service life of A/C condenser tubes, and will be immediate value to those classes with known erosion/corrosion problems.” Also reported were the results of a Navsses conducted fleet techeval, which confirmed that the tube inserts afforded excellent protection against erosion/corrosion, even when installed in tubes which already had advanced pitting. Figures 1, 2 and 3 are typical designs of a tube insert for this application.

At ASEC, we recommend the use of the tube insert in Figure 3. The feathered ends provide a smooth transition of the fluid from the insert to the parent tube. However, this design is more costly than Figure 1. Figure 1 should only be considered when the unit is going to be retired within a couple of years. Figure 1 has a tendency to transfer the erosion problem to the end of the tube insert. Figure 4 represents how a tube insert with a flared end and feathered end is positioned within a unit. The end of the parent tube is not completely protected. In Figure 5 with the use of a flanged end and feathered end, the parent tube is completely protected on the inlet-end and the outlet-end of the ferrule provides a smooth transition. The angle on the outlet-end should not be in excess of 15 degrees.

Tube Inserts For Falling Film Heat Exchangers

Here is where the design engineer can be creative. There are many designs and configurations for tube inserts in this application. The purpose of the tube insert is to induce a fluid to “fall” down the ID of the heat exchanger tube. The following, Figures 4 through 6, are representations of the various types of falling film inserts that have been produced over the years. We do not have any recommendations as to the benefits of one design over another.

High Temperature Applications

In applications where extremely elevated temperatures (1650 F) are present on the tube side of the exchanger care has to be taken not to warp the tube sheet. The use of tube inserts addresses this problem. Typically the tube insert has an hour glass form, creating an air gap between the tube insert and the parent tube. The gap is wrapped with high temperature (2300 F) ceramic paper. The paper is taped in place. We recommend taping the full length. There are two advantages for full length tape:

  1.  Higher temperature ceramic paper can be compressed on to the tube insert
  2. The tape protects the ceramic paper which cannot withstand even minor abuse.

The tube insert extends out of the tube and that space is filled with castable refractory. Some tube inserts have anchors that become imbedded into the refractory; others have pins with ceramic paper washers to set the tube insert at a specific height from the tube sheet. The ceramic washer inhibits heat transfer from the tube insert to the tube sheet. Figure 8 represents a typical design with high temperature paper. Figure 9 represents how a high temperature tube insert is positioned within a unit.

Aditya Steel has manufactured a unique ferrule assembly for use in high temperature applications. The ferrule assembly consists of four components:

  • FERRULE
  • CERAMIC FIBER PAPER
  • CERAMIC FIBER WASHER
  • STANDOFF TUBE

The ferrule is a metal tube insert formed to suit the application, and is completely wrapped with ceramic fiber paper of a suitable temperature rating, and completely taped. The taping is done under pressure, resulting in the compression of the ceramic fiber paper. A ceramic fiber washer is provided, sized to the application. The standoff tube is typically the same alloy as the ferrule and the same size as the heat exchanger tube. The components are assembled together as shown on the attached drawing.

Advantages

There are a number of advantages to this system:

  • The ferrules can be removed, inspected, and if necessary, sent back to the factory for new ceramic fiber paper and taping, before returning to the unit.
  • Only the ferrules that are worn out need to be replaced. This can be accomplished without the removal of the refractory.
  • The design does not have any metal to metal contact from the ferrule to the tube sheet or the heat exchanger tube.

The purpose of the Tube Ferrule Inserts

1)      Protect inlet-end erosion &  corrosion
2)      Act as a protective layer
3)      Reduce the medium impact
4)      Transfer extremely high heat past the tube sheet to the exchanger tubes.

Common problems at Shell & Tube Type Heat Exchangers

1.       Tube-end erosion/corrosion
2.       Stress Corrosion Cracking
3.       Crevice corrosion
4.       Localized pitting
5.       Ammonia grooving
6.       Improper tube expansion
7.       Weakened tube-to-tube sheet joints

Inconel Alloy 601 Ferrule Tube Inserts

Inconel 601 nickel-chromium-iron alloy is a general-purpose engineering material for applications that require resistance to heat and corrosion. The outstanding characteristic of Inconel 601 is its resistance to high-temperature oxidation. The alloy also has good resistance to aqueous corrosion, has high mechanical strength, and is readily formed, machined, and welded.

Inconel Alloy 602 Ferrule Tube Inserts

INCONEL 602 Ferrules covers nickel alloy. These alloys are classified into different grades according to their chemical composition. Inconel 602 Alloy covers Ni-Cr-Fe-Al alloy UNS N06025. Alloy 602 is a high carbon nickel-chromium-iron alloy with the addition of the micro-alloying elements titanium and zirconium together with aluminum and yttrium. It is normally supplied in the solution-annealed condition with an oxidized and descaled surface. The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Inconel Alloy 602CA Ferrule Tube Inserts

Alloy 602CA is a high-temperature alloy that is resistant to metal dusting. Nicrofer 6025 HT, 602CA is a high-carbon, nickel-chromium-iron alloy with micro-alloying elements of titanium, zirconium, aluminum, and yttrium. With an operating temperature of up to 1150⁰C (2102⁰F), 602CA has shown exceptional resistance to oxidation at high temperatures.
ADITYA STEEL ENGG. CO. has provided 602CA in both seamless and seam welded ferrules. Seamless ferrules are available from 21.30mm (0.75”) to 50.8mm (2.00”) OD. Welded ferrules are available from 23mm OD to 50.8mm OD, with the wall thickness of 1.65mm(.065”) and 3mm (.118”).
