Hammer Union Pressure Ratings Overview
What Are Hammer Union Pressure Ratings?
You rely on hammer union pressure ratings to determine the maximum pressure a union can safely handle during oilfield operations. These ratings help you match the right equipment to the demands of your job.
In the context of oilfield equipment, hammer unions are specialized pipe fittings that allow rapid assembly and disassembly for fluid transfer. Each union receives a pressure rating based on its Cold Working Pressure (CWP), which is the highest pressure it can safely withstand at normal operating temperatures.
Manufacturers also test each union at a higher pressure, known as the test pressure, to verify its strength and integrity.
| Term | Description |
|---|---|
| Hammer Unions | Specialized pipe fittings for rapid assembly and disassembly in fluid transfer applications. |
| CWP (Cold Working Pressure) | The maximum pressure the union can safely handle under normal operating temperatures. |
| Test Pressure | Pressure at which the union is hydrostatically tested to verify its integrity and strength. |
Alienfrac offers a comprehensive range of hammer unions with pressure ratings from 1,000 psi to 15,000 psi. This wide selection ensures you can always find the right union for your specific application.
