Bulk Figure 602/1002/1502 Hammer Union Seals Manufacturer for Oilfield Applications

Introduction to High-Performance Hammer Union Seals

---

Hammer Union Seals (also known as Lip Seals) are critical components used in the oil and gas industry to ensure leak-free connections between hammer union joints. Designed to withstand extreme pressures and harsh chemical environments, these seals are essential for high-pressure flow lines, fracturing, acidizing, and cementing.

As a leading ISO9001 certified rubber seal manufacturer, SHQN (Royal Way) provides premium-grade hammer union seals that are fully interchangeable with standard industry figure numbers. Our seals are engineered to provide a tight, dependable seal even in the most demanding oilfield conditions.

Technical Specifications & Working Pressure

Our hammer union seals are available in various sizes (1” to 4”) and configurations to match specific service requirements.

Material Comparison: Choosing the Right Elastomer

---

The performance of a hammer union seal depends heavily on the material. At Qinuo (SHQN), we offer three primary elastomers to suit different oilfield mediums:

1. Nitrile (NBR/Buna-N)

• Temperature Range: -30°C to +100°C (-22°F to +212°F)

• Best For: General oil and water service, drilling mud, and hydraulic fluids.

• Advantage: Cost-effective, excellent abrasion resistance.

2. FKM / Fluorocarbon

• Temperature Range: -20°C to +200°C (-4°F to +392°F)

• Best For: High-temperature applications and aggressive chemicals.

• Advantage: Superior resistance to heat, chemicals, and ozone.

3. HNBR (Hydrogenated Nitrile)

• Temperature Range: -40°C to +150°C (-40°F to +302°F)

• Best For: Sour Gas (H2S) service and high-pressure CO2 environments.

• Advantage: Exceptional mechanical strength and wear resistance.

Key Features of SHQN Hammer Union Seals

---

• Interchangeability: Precision-molded to be compatible with all major hammer union brands used in global oilfields.

• Superior Sealing: The lip seal design ensures that internal pressure energizes the seal, providing a tighter fit as pressure increases.

• High Capacity Production: With over 30 vulcanization presses, we maintain a monthly capacity of 20+ tons, ensuring fast delivery for bulk orders.

• Quality Assurance: Manufactured under a strict ISO9001 quality management system, ensuring every seal meets API-6A dimensional standards.

Oilfield Applications

---

Our seals are widely used in the following energy sectors:

• Well Completion & Stimulation: Hydraulic fracturing and acidizing.

• Drilling Operations: Mud pump manifolds and flow lines.

• Midstream Transport: Temporary pipework and manifold trailers.

• Offshore & Onshore Rigs: Cementing units and high-pressure gas lines.
