Detailed Information:

We are one of the leading manufacturers of copper-nickel ferrule inserts, also called Copper Nickel C70600 and C71500 (70/30), at Ratnaexports. We simultaneously manufacture “Curp Nickel Ferrule Inserts(Cu-Ni Inserts).” As the name implies, tube inserts and tube ferrules are metal inserts inserted into the tube end of the shell and tube heat exchanger tube to protect the mouth ends of the tube. In shell and tube heat exchangers, tube inserts protect the tubes from corrosion. 

As most tube failures occur within the first couple of inches of the heat exchanger tube inlet-end, the need for this Tube Ferrule arises. Condensers and heat exchangers must have thin wall coverings that can be extended fully into the inlet end to solve this problem. A Ratnaexports.com tube insert is a tube insert that ensures an easy, smooth transition between the fluid passing through it and the condenser or heat exchanger tube from the tube insert. We offer two types of tube inserts: metal and plastic/Delrin tube inserts. 

Ratna Exports provides excellent service to our clients. Using premium raw materials, advanced machines, tools, and technologies, we manufacture the best quality Cupro Nickel 90/10 Ferrule Inserts that are highly durable. The Cupro Nickel 90/10 Compression Tube Inserts are designed and developed following national standards. Professional experts conduct quality tests.

The company knows how important packaging is, so it uses the best quality material to package Cupro Nickel 90/10 Compression Tube Fittings for transportation. The company uses the best packing materials to prevent transportation harm to packing Cupro Nickel 90/10 Compression Tube Fittings. By partnering with logistic partners and using the fastest shipping method, RatnaExports.com assures valuable clients that the fittings are delivered in a damaged condition to their valuable clients without any delays.

There is a wide variety of Cupro Nickel 90 / 10 Ferrule Inserts, and we can provide them in all sizes, shapes, thicknesses of walls and to meet customer requirements. We can also customize the Fittings according to the customer’s requirements.

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.

Types Of Tube Insert/Ferrules-Choose From Our Standard Design Modules. If You Do Not Have a Drawing

Straight Tube Ferrule Insert

These are the primary form of Tube Ferrules. Very economical and serves the primary purpose of Tube Mouth Protection. Ideal when there is not enough space at Tube Mouth for Ferrule Flares.

Bar Stock Ferrule Insert

These are machined from Solid Round Bars. Useful for small sizes and precision. Commonly used in metal when Pipes are not available for Construction.

Standard Flare Ferrule Insert

Flaring serves the purpose of holding the Ferrule Inserts with Tubes. With Single Flare on the outer side, this is the most commonly used and widely accepted Ferrule Inserts. Also does not necessarily require the use of Ceramic Fiber Paper.

Single Flare With Back Cut Tube Insert

A variation in the above design has a degree at the tail. Helps in a more straightforward installation where there may be hindrance/aberration in the tubes.

Single Flare Long Tube Insert

With Extra Length after Flaring, this Tube Insert is functional when used with Ceramic Fiber Paper. Sometimes these are hammered inside the Tube for proper fit.

Double Flare Stepped Tube Insert

With Double Flaring, this Tube Insert is functional with Ceramic Fiber Paper.

Double End Flare Tube Insert

It has Flaring at both Start and End. A degree may defer at both ends to ensure correct installation.

Who Uses Tube Inserts?

Any production process that requires the use of heat exchangers will benefit from the use of tube inserts. Tube inserts improve the tube side performance of heat exchangers by modifying the flow stream characteristics to enhance heat transfer. If you use heat exchangers, tube inserts will improve efficiency and increase tube life, both of which will produce substantial production and cost benefits.

Why Use Tube Inserts?

The following problems are common in shell & tube type exchangers:

  • Tube-end erosion/corrosion
  • Stress corrosion cracking
  • Crevice corrosion
  • Localized pitting
  • Ammonia grooving
  • Improper tube expansion
  • Weakened tube-to-tube sheet joints

Packing:

We understand the importance of packaging, especially in the case of international shipments, as the consignment has to go through several channels to reach the final destination. Thus we take proper care of packing.

We pack our goods in various ways depending on the products. The different ways in which our products are packed are:

 Shrink-wrapped

Wooden Boxes

Wooden Pallets

Wooden Crates

Carton boxes

Marking:

All our products will have complete marking details for our supply test certificates.

The marking is transferred from the product from which it is cut to cut pieces of Pipes, Sheets, or Round Bars. In such cases, we provide a Letter confirming the marking transfer and a picture of the product from which it is cut.

Cu Ni Ferrule Inserts Application

We can use plugs in some high-temperature/pressure heat exchangers for permanent plugging of condenser tubes and for plugging holes in the tubes of tube sheets. Before heat exchange, tubes with leaks can be plugged into tube plugs.
