A hammer union is a type of mechanical joint used to connect two sections of piping or tubing in a temporary or permanent manner. It is commonly used in oil and gas drilling operations, as well as other industries that involve high-pressure fluid transfer.

Here are the key features and components of a typical hammer union:

Design: A hammer union consists of three main parts: a threaded male half, a threaded female half, and a nut. The male and female halves have corresponding threaded connections that can be easily joined together by tightening the nut.

Threaded Connections: The male and female halves of a hammer union have external threads that match with each other. These threads enable a secure and tight connection between the two sections of piping or tubing.

Seal: Hammer unions often include a resilient seal, such as a rubber O-ring or a lip-type seal, which is placed inside the female half. When the male and female halves are joined together, the seal ensures a tight and leak-resistant connection.

Nut and Sub: The nut is used to tighten the male and female halves together. It is typically hexagonal in shape, allowing for easy tightening using a wrench. The sub is a smaller threaded section located near the nut, which helps to protect the seal and prevent damage during the tightening process.

Pressure Rating: Hammer unions are designed to handle high-pressure applications. They are available in various pressure ratings, typically ranging from 1,000 to 20,000 pounds per square inch (psi) or higher, depending on the specific application and industry requirements.

Sizes: Hammer unions come in a range of sizes to accommodate different pipe diameters. Common sizes include 1", 2", 3", 4", 5", and 6", although larger sizes are available for specific applications.

Versatility: Hammer unions are versatile and can be used in a variety of applications where temporary or permanent connections are required, particularly in industries such as oil and gas, drilling, fracking, well testing, and pipeline maintenance.

The name "hammer union" comes from the fact that the union can be tightened using a hammer to strike the nut and achieve a secure connection. This feature allows for quick assembly and disassembly of the joint, making it convenient for applications where frequent connections and disconnections are needed.

It is important to note that hammer unions should be properly maintained and inspected to ensure their integrity and prevent leaks. Regular inspections, replacement of worn seals, and adherence to industry standards and guidelines are essential for safe and reliable operation.

Overall, hammer unions provide a reliable and robust solution for connecting high-pressure piping or tubing in various industrial applications. Their ease of assembly, disassembly, and versatility make them a popular choice in industries that require frequent and temporary connections.

A Fig 206 hose union is a type of heavy-duty, high-pressure flow line connector that is commonly found in chemical plants, on marine dredging vessels, in strip mines, and in the oil industry. It is similar to a Fig 200 hose union, but it has an O-ring mounted in a machined groove on the male half for added sealing properties. This makes it ideal for applications where there is a risk of leaks, such as when handling corrosive fluids or high-pressure gases.

Applications:
Fig 206 hose unions are used in a variety of applications where high pressure and/or corrosive fluids are present. Some common applications include:

• Oil and gas production
• Chemical processing
• Water treatment
• Mining
• Construction

Advantages:
The advantages of Fig 206 hose unions include:

• High pressure rating
• Temperature resistance
• Corrosion resistance
• Durability
• Easy to install and maintain.
