What is a very high pressure “cone & thread” connection?

In the world of industry and energy, you have to be careful, especially when handling gases and liquids at high pressures.

High-quality, high-performance connections are used to facilitate the safety and efficiency of the equipment.

An example of such quality connections is the “cone & thread” of very high pressure. I’ll explain in a moment.

But let’s see… What is a “cone & thread” connection?

The first thing you should know is that it is a pipe fitting. But not just any pipe, no; cone & thread fittings are used to connect high-pressure pipes.

This connection consists of two parts: on the one hand, the male cone and on the other hand, the female cone with a thread.

The thread is screwed into the pipe and the cone is inserted, thus creating a tight seal. In fact, cone & thread connections are known for their high vibration resistance. And let’s not forget their ability to withstand high pressures.

And as I know that you like everything technical I leave you a technical data sheet of fittings and valves of very high pressure. Just click on the download button.

When and why are very high pressure cone & thread connections used?

These powerful connections are logically used in industries that require handling of gases and liquids at high pressures, such as oil and gas.

They are designed to withstand extremely high pressures and are used in test equipment, measuring equipment and transfer systems, as we will see shortly.

Safety first, you know.

Types of very high pressure valves

In addition to the “cone & thread” connections, there are four types of very high pressure valves on the market that provide added safety and high performance. These are:

• Ball valves
• Check valves
• Globe valves

Each one has its own characteristics and applications, so depending on what you need, you will have to choose one valve or another.

But be careful: as with the “cone & thread” connections, make sure that the valve you buy is of high quality, able to withstand high pressure and temperature conditions.

How very high pressure cone & thread connections work

Very similar to the standard “cone & thread”.

The hermetic seal is created by joining the cone and the female; thus, the connection can withstand the pressure of the fluid without any problem, no matter how high it may be.

They are vibration-resistant connections, therefore ideal for use in industrial environments.

Benefits of very high pressure cone & thread connections

Keep an eye out, because the use of these special connections brings benefits such as these:

• Vibration resistance: as we have already mentioned, they are designed to resist impacts and vibrations like champions, making them ideal for industrial environments.
• Withstand high pressures: as their name suggests, they are perfect connections to withstand extremely high pressures.
• They are durable: very high pressure “cone & thread” connections are made of durable, corrosion-resistant materials, so you don’t have to worry if you use them in corrosive environments.
• They’re easy to install – and easy to remove, mind you, so they’re great for applications that require frequent changes.

Given the benefits, shall we move on to applications?

Typical applications of very high pressure “cone & thread” connections

There are several, of which we have highlighted these three:

High pressure test systems

Typical, no, very typical in the oil and gas industry.

These systems are used to test the integrity of equipment and pipelines before they go into operation.

You know what they say: better safe than sorry.

High pressure measurement systems

Yes, very high pressure “cone & thread” are also used in high pressure measurement systems to measure the flow and pressure of liquids and gases.

Liquid and gas transfer systems

Measuring… and handling, of course.

Very high pressure “cone & thread” connections are also used in the oil and gas industry to transfer liquids and gases, as well as in other industries that may require high pressure treatment of these two elements.

Very high pressure “Cone & thread”: made for endurance

With that ability to withstand you’ll understand why they are essential connections in many equipment and installations in the energy world.

And with those associated benefits – the ability to withstand extremely high pressures, resist vibration and impact, and their ease of installation – they become an ideal choice for applications that require high performance and safety.

If that’s what you’re looking for in your equipment, cone & thread connections are a safe bet.
