Hammer unions (Weco couplings)

Weco couplings: Strong connections for demanding industries
Weco couplings are widely used in industries where pipes are under high pressure and a reliable connection is required. These couplings are used mainly in the oil and gas industry, but also in hydraulic systems and water treatment plants, because of their sturdy construction and easy installation. They ensure a safe and leak-free connection, which is essential in environments where liquids or gases are transported under severe conditions.

Applications of Weco couplings
Weco couplings are designed for environments where pipe systems have to be disconnected and reconnected regularly. In the oil and gas industry, they are used on drilling platforms, pipelines and refineries, where they have to withstand extreme pressure and temperature differences. These couplings also play an important role in the hydraulic sector in transporting liquids under high pressure. They are also used in the water treatment industry, where they contribute to efficient and safe connections within pump systems and filter systems.

Advantages of Weco couplings
The robust construction of Weco couplings ensures that they can withstand severe conditions and intensive use. They are easy to install and can be quickly disconnected, making maintenance and replacement of piping systems easier. Their design minimizes the risk of leaks, which contributes to the safety of industrial processes. They are also available in different designs and sizes, making them suitable for various applications.

How a hammer union works

A hammer union consists of three parts: a male sub, a female sub with seal, and a wing nut. Tighten the nut by hand, then seat it with a hammer blow on the wings — hence the name. The result is a rugged, quickly (dis)assembled connection that handles high pressures and rough treatment.
