Hammer Union Seals Brazil
Overview
Hammer union seals are specialized sealing components used in hammer union connections to ensure leak-proof performance in high-pressure oilfield piping systems. Installed within union joints, these seals create a reliable barrier between connected pipes and equipment, enabling safe fluid transfer.
In Brazil’s oil & gas industry—particularly in offshore and deepwater operations—hammer union seals are widely used in drilling, cementing, and well service applications where quick connection and disconnection of high-pressure lines are required.
Key Features
- High Pressure Resistance
Designed to operate in applications ranging from low pressure to over 15,000 PSI. - Leak-Proof Sealing Performance
Ensures tight sealing between hammer union connections, preventing fluid leakage. - Metal-to-Metal with Elastomer Lip Design
Combines a metal insert with an elastomer sealing lip for enhanced durability and sealing efficiency. - Chemical & Corrosion Resistance
Suitable for exposure to hydrocarbons, acids, drilling fluids, and sour gas (H₂S, CO₂). - High Temperature Capability
Maintains performance in elevated temperature environments. - Easy Installation & Replacement
Enables quick maintenance and reduced downtime in field operations.
Applications
Hammer union seals are widely used across Brazil’s oil & gas operations, including:
- Cementing and fracturing lines
- Mud circulation systems
- Well testing and stimulation equipment
- High-pressure fluid transfer systems
- Offshore drilling rigs and onshore facilities
They are commonly used in hammer union connections such as FIG 100, FIG 200, FIG 602, FIG 1002, FIG 1502, and FIG 2002.
Types of Hammer Union Seals
Standard Lip Seals
Feature an elastomer lip bonded to a metal ring, providing reliable sealing in general applications.
O-Ring Type Seals
Utilize elastomer O-rings for sealing in lower pressure applications.
PTFE Lip Seals
Offer enhanced chemical resistance and reduced friction for specialized environments.
Sour Service Seals
Designed for applications involving H₂S and other corrosive gases.
Materials Used
Hammer union seals are manufactured using high-performance materials selected for durability and compatibility:
- NBR (Nitrile Rubber) – Suitable for general oilfield applications
- HNBR – Enhanced resistance to temperature and chemicals
- FKM (Viton®) – High temperature and chemical resistance
- AFLAS (FEPM) – Excellent resistance to sour gas environments
- PTFE – Superior chemical resistance and low friction
- Brass / Stainless Steel Inserts – Provide structural strength and durability
Material selection depends on pressure, temperature, and fluid conditions.
