Single Sphere Molded Rubber Expansion Joints Stainless Steel (Series SAMS)

These Stainless Steel Single-Sphere Molded Rubber Expansion Joints (Series SAMS) feature flanged ends, so they are easily installed. These rubber and stainless steel expansion joints are suitable for a range of applications and operating conditions.

FEATURES

  • Applicable for suction and delivery (discharge).
  • Provides sound and vibration isolation.
  • Gaskets and packing are not required.
  • Floating flanges allow for easy installation.
  • Prevents piping system and equipment breakdown by absorbing elongation and contraction caused by temperature variances.
  • Absorbs water pulsation and minimizes water hammering.

APPLICATIONS

  • Pumps & air compressors in air conditioning system & sanitary equipment.
  • Refrigeration systems and blowers in industrial plant equipment.
  • Feed-water and drainage equipment in marine piping systems.
  • Applicable for use in power generation and chemical plants.
  • Marine applications
