Hammer Union Seals for Drilling and Well Service Applications

Product Introduction

Our premium Hammer Union Seals are engineered to provide superior sealing integrity for the global oil and gas industry. Specifically designed for drilling, cementing, and well service applications, these seals ensure a leak-proof connection in high-pressure piping systems. Whether you are operating in standard oilfield conditions or extreme sour gas (H2S) environments, our seals deliver the reliability needed to prevent costly downtime and ensure personnel safety.

Core Performance Features

1. Leak-Proof Engineering: Precision-molded geometry ensures a perfect fit within the union’s seal groove, preventing fluid bypass under high vibration.
2. Anti-Extrusion Properties: High-modulus materials resist extrusion and "nibbling" even during extreme pressure fluctuations.
3. Rugged Durability: Excellent resistance to abrasion from sand, proppants, and slurry mixtures commonly found in drilling mud and fracking fluids.
4. Interchangeable Design: Fully compatible with industry-standard Figure numbers used in global oilfield operations.

Material Comparison & Selection

Selecting the correct elastomer is vital for maximizing the lifespan of your well service equipment. We offer several high-performance compounds:

NBR (Nitrile / Buna-N):
Best for: Standard water, oil, and mud service.
Pros: High abrasion resistance and cost-efficiency for general drilling.

HNBR (Hydrogenated Nitrile):
Best for: High-temperature and Sour Gas (H2S) environments.
Pros: Superior mechanical strength and chemical stability compared to standard Nitrile.

FKM (Fluorocarbon):
Best for: Aggressive chemical exposure and extreme heat.
Pros: Exceptional resistance to acids, hydrocarbons, and high-temperature steam.

PTFE:
Best for: Maximum chemical inertness.
Pros: Virtually unaffected by all oilfield chemicals; low friction coefficient.

Primary Application Scope

These seals are essential components in various "iron" and flowline configurations, including:
Drilling Systems: Mud pumps, standpipes, and suction lines.
Well Completion: Fracturing (Frac) manifolds and flow-back equipment.
Well Intervention: Acidizing, cementing units, and coiled tubing reels.
Testing & Production: Separators, choke manifolds, and well testing lines.
Offshore Operations: Marine risers and high-pressure fluid transfer on rigs.

Industry Standards & Compatibility

Our Hammer Union Seals are designed to be compatible with all major industry-standard union configurations. We support a wide range of "Figures" to match your existing inventory:
