Introduction

Polyurethane valve seals are critical components in the petroleum industry, utilized for their exceptional durability and sealing capabilities. This article examines their applications, benefits, and a case study highlighting Borise Company solutions.

Properties of Polyurethane Valve Seals

Polyurethane is known for its high tensile strength, abrasion resistance, and flexibility. These properties make it an ideal material for valve seals, which require a tight seal under extreme conditions commonly found in petroleum processing. The following parameters characterize polyurethane:

• Tensile Strength: 30-50 MPa
• Elongation at Break: 400-700%
• Hardness: 60-95 Shore A
• Operating Temperature Range: -40°C to 90°C

Applications in the Petroleum Industry

In the petroleum industry, valve seals are subjected to challenging environments, including high pressures, temperature fluctuations, and corrosive substances. Polyurethane valve seals are used in:

• Hydraulic fracturing equipment
• Pipeline transportation systems
• Oil and gas drilling rigs
• Refinery processing units

Benefits of Polyurethane Valve Seals

The use of polyurethane valve seals provides several benefits in petroleum operations:

• Enhanced lifespan due to superior wear resistance
• Reduced maintenance costs and downtime
• Improved sealing capability preventing leaks and spills
