Oil & Gas Mechanical Seals & Sealing Systems

Engineering Focus: API 682 Heavy-Duty Mechanical Seals for Crude Oil Refining, LPG, and Hydrocarbon Pipelines

Oil refineries, offshore platforms, and hydrocarbon pipeline terminals operate under extreme risks of explosion, vapor flashing, and environmental catastrophe. Pumping volatile LPG, hot residue, sour crude, and hazardous aromatics necessitates mechanical seals engineered to API 682 specifications with proven zero-emission secondary containment. USEC provides heavy-duty cartridge and metal bellows seals.

The oil and gas industry, one operating in extreme conditions where reinforced and reliable seals must withstand high pressures and temperatures, as well as corrosive materials. Our mechanical seals are designed for critical applications like drilling, refining, and pipeline operations.

We commit to safety and performance and ensure our solution meets the exact demands of the energy sector.

Critical Operating Challenges in Oil & Gas

Volatile Light Hydrocarbon Flashing

LPG and light naphtha vaporize instantaneously at atmospheric pressure, causing dry-running seal face destruction.

Sour Crude H2S Stress Cracking

Hydrogen sulfide and sulfur contaminants cause sulfide stress cracking in standard stainless steels.

Extreme Temperature Extremes (-40°C to +400°C)

Atmospheric distillation bottoms and cryogenic LPG require wide-spectrum thermal resilience.
