High-Pressure 15,000 PSI Hammer Union Lip Seal with Oilfield Grade NBR and Self-energized Design

High-Pressure Hammer Union Lip Seals: Rated for 15,000 PSI

Product Introduction and Design Engineering

The High-Pressure Hammer Union Lip Seal is a precision-engineered sealing element designed to meet the extreme demands of the global energy sector. These lip-style seals are specifically manufactured to provide a dynamic sealing action; as internal pressure increases, the seal lips are energized and pressed more firmly against the union walls, ensuring a zero-leak connection. This design is particularly critical for high-pressure flowlines where vibrations and pressure surges are common. Produced by Qinuo, these seals utilize advanced elastomer technology to prevent fluid bypass in critical manifold systems, protecting both personnel and equipment from the hazards of high-pressure leaks.

Material Science and Performance Benefits

Our hammer union seals are available in a variety of high-performance elastomers to suit different environmental conditions.

Nitrile (NBR,Buna-N)
This is the standard material for oilfield applications, offering excellent resistance to water, hydraulic fluids, and petroleum-based products. It provides high tensile strength and great wear resistance for general service.

HNBR (Hydrogenated Nitrile)
For operations involving higher temperatures and exposure to sour gas H2S, HNBR is the preferred choice. It offers superior heat resistance and maintains its mechanical properties under more aggressive chemical conditions.

FKM (Fluoroelastomer)
When chemical corrosion and extreme heat are the primary concerns, FKM provides the highest level of protection. It is resistant to a wide range of chemicals and maintains a seal at temperatures exceeding 400 degrees Fahrenheit.

Technical Specifications Table

Primary Application Range

These 15,000 PSI rated lip seals are essential for high-intensity upstream operations.

1. Hydraulic Fracturing
In fracking operations, discharge lines must handle abrasive slurries at extremely high pressures. Our lip seals provide the necessary resilience to prevent erosion and leakage during these high-volume pumping cycles.

2. Well Cementing and Acidizing
During the completion phase, these seals ensure that cement slurries and acidizing chemicals are contained within the flowlines, even when the system is operating at maximum pressure capacity.

3. Mud Circulation Systems
The seals are used in mud pump manifolds and standpipe systems to manage the flow of drilling fluids. The lip design helps to wipe away debris, ensuring a clean sealing surface.

4. Flowback and Testing
During well testing, the seals manage the high-pressure output of the reservoir, providing a reliable barrier against gas and fluid leaks as the well is evaluated.
