Product Specification

Hammer Union Seals for Drilling and Well Service Applications

Product Introduction

---

Our high-performance Hammer Union Seals are specifically engineered to withstand the rigorous demands of global drilling and well service operations. These seals, also known as lip seals, provide a critical high-pressure barrier in hammer union connections, ensuring leak-free performance during fluid transfer. Designed for compatibility with standard industry figures, our seals are the preferred choice for service companies requiring reliability in manifolds, flowlines, and high-pressure pumping equipment.

Material Selection & Performance Comparison

---

Choosing the correct elastomer is vital for the safety and efficiency of well service applications. We provide specialized materials to suit diverse downhole and surface conditions:

• NBR (Nitrile / Buna-N):

  • Application: Standard drilling mud, water transfer, and general oil service.

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

  • Benefits: Highly cost-effective with excellent abrasion resistance.

• HNBR (Hydrogenated Nitrile):

  • Application: Modern drilling environments with exposure to crude oil and H2S (Sour Gas).

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

  • Benefits: Superior mechanical strength and high-temperature resilience compared to standard NBR.

• FKM (Fluorocarbon ):

  • Application: High-temperature well services and aggressive chemical processing.

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

  • Benefits: Exceptional resistance to heat, acids, and aromatic hydrocarbons.

• PTFE :

  • Application: Extreme chemical exposure and specialized backup ring designs.

  • Benefits: Virtually universal chemical resistance and very low friction.

Pressure Ratings by Connection Figure

---

Our seals are molded to exact tolerances to ensure they match the pressure requirements of standard connection figures:

• Fig 602 Seals: Designed for pressures up to 6,000 PSI.

• Fig 1002 Seals: Designed for pressures up to 10,000 PSI.

• Fig 1502 Seals: Heavy-duty design for high-pressure service up to 15,000 PSI.

Key Features & Advantages

---

• Pressure-Energized Design: The lip seal geometry utilizes internal line pressure to increase sealing force against the union wall.

• Anti-Extrusion Reinforcement: For high-pressure variants (Fig 1502), we offer seals with integrated metal rings to prevent the rubber from "washing out" under extreme flow.

• Universal Compatibility: Manufactured to meet universal industry standards, ensuring seamless interchangeability with all standard-compliant hammer union pipe fittings.

• Abrasion & Erosion Resistance: Specially formulated to resist the erosive nature of sand-laden fracking fluids and drilling mud.

Application Scope

---

Our hammer union seals are essential for a wide range of Drilling and Well Service activities:

• Hydraulic Fracturing: High-pressure pumping and fluid manifolds.

• Cementing & Acidizing: Secure connections for stimulation chemicals and cement slurries.

• Well Completion: Flowline connections and temporary piping systems.

• Drilling Operations: Suction and discharge lines for mud pumps and standpipes.

• Flowback Services: Safe containment of fluids during well cleanup.
