Cone and Thread Tube Fittings

Cone and thread (C&T) connectors are a reliable choice for "middle pressures" of up to 15,000 psi. However, they have proven to be successful in high-pressure situations as well, with a maximum pressure capacity of up to 150,000 psi. The use of C&T connectors involves chamfering or coning the tube and countersinking it into the fitting to create a secure and tight connection. 

Achieving a tight seal requires precision-formed tube ends with excellent surface polish and threading. These steps must be completed on-site, which can add significant time and cost to the installation process. Despite this, C&T fittings, like compression fittings, can be disassembled and reassembled for servicing. Additional care and attention during installation can ensure a reliable and long-lasting connection for your system.

Although procedures such as C&T fittings can be effective, replicating or maintaining the same results is not always possible. It's important to note that these procedures can also lead to contamination of the tube's ID with metal shavings and cutting oil, which in turn, requires additional cleaning steps. Additionally, utilizing C&T fittings requires specialized equipment and training. It's worth mentioning that since the threading of the joints occurs under unregulated settings, vibrations can cause the fittings to loosen. Therefore, it's essential to take necessary precautions to ensure the fittings remain secure and the procedure is carried out with care.

We design these connections to provide exceptional performance and reliability, even in challenging environments and critical applications. 

They are ideal for use in industries such as oil and gas, chemical processing, and aerospace, where precision and durability are essential. With their exceptional quality and performance, Female Medium-Pressure Coned and Threaded Connections are an excellent choice for any application that demands the best in fittings technology.

What are the types of Cone and Thread Fittings?

Cone and thread fittings are an essential component in high-pressure systems. As a leading Cone and Thread fittings supplier in India, they are designed with a gland, collar, female port, and weep hole, which enable service technicians to verify that the fitting has been installed correctly and check for any potential leaks. It is crucial to use a tube with a thicker wall to ensure safe operation, especially when working with high-pressure applications. Additionally, regular maintenance and inspection of these fittings are necessary to ensure optimal performance and prevent any potential safety hazards.

Cone and thread tube fittings are a type of fitting used to connect and seal tubing in high-pressure and high-temperature applications. There are several types of cone and thread tube fittings, including:

Straight fittings: These are the most common type of cone and thread fittings, and they consist of a male and female connection that fit together to create a seal. Straight fittings are available in various sizes and materials to suit different applications.

Elbow fittings: These fittings allow for a change of direction in the tubing, making them useful in applications where space is limited. Elbow fittings are available in different angles, such as 45° and 90°, to suit different needs.

Tee fittings: These fittings allow for the connection of three pieces of tubing, creating a T-shape. Tee fittings are available in different sizes and materials to suit different applications.

Cross fittings: These fittings allow for the connection of four pieces of tubing, creating a cross shape. Cross fittings are available in different sizes and materials to suit different applications.

Union fittings: These fittings allow for the easy disconnection of tubing for maintenance or repair. Union fittings consist of a male and female connection that fit together and can be easily disconnected when needed.

Reducer fittings: These fittings allow for the connection of two pieces of tubing with different diameters. Reducer fittings are available in various sizes and materials to suit different applications.

Bulkhead fittings: These fittings are designed to pass through a panel or wall, allowing for the connection of tubing on either side. Bulkhead fittings are available in different sizes and materials to suit different applications.

Port connectors: These fittings allow for the connection of tubing to a port, such as a valve or pump. Port connectors are available in various sizes and materials to suit different applications.

Overall, cone and thread tube fittings offer a reliable and leak-free connection for high-pressure and high-temperature applications. The type of fitting required will depend on the specific application and the size and material of the tubing being used.

Medium Pressure and High Pressure Cone and Thread Instrumentation Fittings?

The main difference between medium pressure and high pressure Cone and Thread Tube Fittings lies in their design and the maximum pressure they can handle.

Medium pressure Cone and Thread Tube Fittings are designed to handle pressures up to 20,000 psi (1,379 bar) and are typically used in applications such as chemical injection, process control, and hydraulic systems. They have a conical seal and are easy to install and remove, making them a popular choice for a variety of applications.

High pressure Cone and Thread Tube Fittings, on the other hand, are designed to handle much higher pressures, up to 60,000 psi (4,137 bar). They have a larger diameter thread and a flat-bottomed cone seal that is designed to withstand the high pressures involved. High pressure Cone and Thread Tube Fittings are commonly used in oil and gas exploration and production, as well as in other high-pressure applications where reliability and safety are critical.

In summary, the main difference between medium pressure and high pressure Cone and Thread Tube Fittings is the maximum pressure they can handle, with high pressure fittings designed to withstand significantly higher pressures than medium pressure fittings.

Why Instrumxx Industries is the leading C&T Supplier in India.

Firstly the quality of products we supply throughout India is extremely durable and widely applicable. When it comes to Cones and Threads supply, every type we provide is dependable and can be suited for both, high pressure and medium pressure. 

The advantage you receive from Cone and Thread tube fittings is extreme strength, more than 8000 psi are recommended. Now this fitting creates a seal between the metal parts restricting any reduced force or leakage.
