PetroSan Oilfield Engineering Co. is one the prestigious manufacturer and fabricators of tube insert sleeves or heat exchanger ferrules and boiler ferrules. We produce accordance with ISO 9001 criteria, we meticulously create quality control methods and use high-quality materials to manufacture, export, and provide heat exchanger tubes and boiler tubes.
In shell and tube type heat exchangers, tube insert sleeves, also known as Ferrules, are used to protect the tubes. The ends of the heat exchanger tubes are fitted with ferrules or tube inserts.
Tube insert sleeve (Ferrules).
Material: Typically made from corrosion-resistant alloys like nickel alloy, Inconel alloy, stainless steel, titanium, or copper nickel.
Design: Ferrules are designed to withstand high temperatures, pressures, and corrosion, ensuring a reliable seal.
Applications:
- Shell and tube heat exchangers.
- Plate heat exchangers.
- Finned tube heat exchangers.
- Air-cooled heat exchangers.
- Boilers.
Sizes: Various sizes available to fit different tube and pipe diameters.

Heat exchanger ferrules are essential to preserving heat exchanger and boilers dependability and efficiency. To choose the right ferrules for your application, take into consideration criteria like size, design, and compatibility with different materials like Stainless steel 304/304L, 316/316L, Titanium grade 1 or grade 2, Copper nickel Cu-Ni 70-30 or Cu-Ni 90-10, Inconel Alloy 601, Inconel alloy 602CA & Inconel alloy 693 for for high heat tepreture resistant materials.




What is tube insert sleeve or ferrule. ?
Tube insert sleeve and ferrules are 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 PetroSan, we manufacture metal tube inserts for all applications, providing the necessary drawings required.
Tube insert sleeve and ferrules used to reinforce and strengthen the ends of tubes or hoses in various industries, such as:
– Hydraulic systems.
– Pneumatic systems.
– Heat exchanger.
– Boilers.
– Automotive systems.
– Industrial equipment.
Ferrules serve several purposes:
– Prevent tube damage.
– Provide a secure connection.
– Reinforce the tube’s structural integrity.
– Enhance safety and reliability.
They are typically made from materials like metal such as :
