Precision Engineered 6000 PSI NBR Hammer Union Seal for Fig 602 Flow Control

Precision Engineered Hammer Union Seals for Flow Control

Product Overview

Hammer union replacement seals must match the actual flowline connection, groove and fluid service. Provide union manufacturer, figure, nominal size and removed-seal dimensions or drawing. Inspect sealing surfaces and follow the equipment installation and pressure-test procedure before return to service.

Core Performance Features

Dimensional Precision: Engineered to exact tolerances to ensure consistent sealing performance across various "Figure" configurations.
Installed Profile: Confirm the seal seats in the specified groove without unintended intrusion into the fluid passage.
Pressure Cycles: Provide operating cycles and the complete union rating; the replacement seal has no independent universal pressure rating.
Extrusion Control: Review groove clearance, compound, hardness and any specified support ring against the equipment drawing.

Material Comparison & Selection Criteria

The efficiency of a flow control system depends heavily on selecting the correct seal material. We provide various high-grade elastomers tailored for specific media:

1. NBR (Nitrile):
Best for: Standard water, oil, and mud service.
Advantages: Excellent abrasion resistance and high elasticity for general-purpose applications.

2. HNBR (Hydrogenated Nitrile):
Selection: Exact HNBR compound qualification is required for actual H2S exposure, temperature and decompression conditions.
Advantages: Superior thermal stability and resistance to oil-based fluids at high temperatures.

3. FKM (Fluorocarbon):
Best for: High-temperature operations and aggressive chemical flow.
Advantages: Exceptional resistance to heat, ozone, and a wide array of chemicals and solvents.

4. PTFE (Polytetrafluoroethylene):
Best for: Maximum chemical compatibility and low-friction requirements.
Selection: Confirm PTFE grade, construction, creep allowance and medium-specific service limits.

Technical Specifications

Confirm the replacement specification against the actual equipment and service conditions:

1. Seal Sizes: 1", 2", 3", 4", and accept custom sizes

2. Working Pressure Range:
Standard Service: Use the complete union assembly rating.
Pressure Limits: Confirm equipment rating and applicable service limits.
Specialized Service: Confirm the complete qualified configuration before use.

3. Temperature Range:
NBR: Confirm selected compound limits for the actual medium and duration
HNBR: Confirm selected compound limits for the actual medium and duration
FKM: Confirm selected compound limits for the actual medium and duration

Application Scope

These precision seals are utilized globally in flow control and fluid transfer applications, including:
1. Hydraulic Fracturing: Managing high-velocity sand and fluid slurries at high pressure.
2. Drilling & Exploration: Mud manifold systems and standpipe sealing.
3. Well Completion: Cementing and acidizing flowlines.
4. Flowline Maintenance: Temporary pipework for well testing and fluid recovery.
5. Industrial Processing: High-pressure chemical and water transfer lines in refineries and plants.

Compatibility & Standardization
