How to Buy the Right Hammer Unions in Dubai

How to Buy the Right Hammer Unions in Dubai Hammer unions are high-pressure flow line connectors that consist of two joints by a threaded nut. They are designed with a coupler with a male thread and inner core (female half), a ball-shaped fitting (male half), and a female thread nut that helps tighten the ball-shaped fitting with the inner core of the coupler.

What to Know When Buying Hammer Unions ●

Hammer unions have a very robust construction and are manufactured using only certified materials with full traceability. The color-coding system on hammer unions indicates their specific configurations and pressure ratings.

● They can operate well at working pressure at ambient temperature ranges from 35 bar (1000 PSI) to 1378 bar (15000 PSI). Approved by DNV, they are designed for hydrogen sulfide applications and are resistant to hydrogen embrittlement.

● Hammer unions also have Fig# stamped on them so that workers can easily identify if it is the right union for their pipe connection or not.

● The most important thing to know about hammer unions is that you must not use union components with different figure series even if they have the same nominal pipe size.

For instance, Hammer Union Fig. 1502 and Hammer Union Fig. 602 may appear to mate easily but, in reality, they have different threads and that can lead to a coupling blow-out causing severe injury, property damage, or significant loss of the product being conveyed through a pipeline.

Thus, you must never interchange different Figure Series, no matter if they have the same nominal pipe size.

Here is the list of different figure series for hammer unions so that you can identify which Hammer Union Fig# you need for your application in Dubai: Hammer Union Fig 100: It is used on low-pressure manifolds, tank truck transfer, and in other applications such as running water, air, gas, or oil up to 1000 psi NSCWP Hammer Union Fig 200: It is used in general service applications where you need to convey steam, air, water, glycol, oil, or gas up to 2,000 psi NSCWP. Hammer Union Fig 206: It is similar to hammer union fig 200 but comes with an O-ring mounted in the machine groove on the male half for enhanced sealing properties. It doesn’t seal when threaded with fig 200. So, do not intermix or interchange them. And it is used for running water, air, oil, or gas up to 2,000 psi NSCWP. 1. Hammer Union Fig 400: It can be found on 2inches Kelly hoses and can be used for up to 4,000 psi NSCWP. 2. Hammer Union Fig 602: Its lip-type seal reduces fluid turbulence while creating a pressure seal and it can be used in mud lines, manifold services, and truck mounting applications that transfer air, water, oil, gas, or mud up to 6,000 psi NSCWP. 3. Hammer Union Fig 1002: It is similar to Fig 602 and can be used in high-pressure systems and truck mounting applications running air, water, gas, oil, or mud up to 10,000 psi NSCWP. 4. Hammer Union Fig 1502: Its lip-type seal also minimizes fluid turbulence while creating a pressure seal and it is best for use in mud lines, manifold service, and truck mounting applications that run water, air, oil, gas, or mud up to 15,000 psi NSCWP. So, make sure that you choose the right figure series when buying hammer unions in Dubai.
