  • Oil & Gas

industry sectors

  • Downstream Processing

API 682

Operating Parameters

Pressure: up to 20.7 bar (300 psi)

Temperature: -73°C to 427°C (-100°F to 800°F)

Speed: up to 23 m/s (75 fps)

Sizes: 28.2 to 150 mm (1.110 to 5.906 inches)

Features & Benefits
  • Longer service life ensure by the use of edge-welded, thick-plate Alloy 718 bellows that comply with NACE MR0103 criteria and can withstand long-term chemical exposure
  • Reliability resulting from the canned face design that eliminates shrink-fit distortions and allows low-leakage performance
  • Prolonged clean operation (on stationary configurations) due to steam purge baffle that eliminates coking
  • Configurable with a rotating or stationary bellows to fit a wide range of high temperature application needs

Utilizes a bolted bellows adapter for convenient repairs when necessary

Shorter version designed to fit pumping equipment with axial length restrictions and when dual seals are required
