Rayjoint - Heat Shrinkable Joint Casing
Colors: Black
Adhesives: Adhesive: Butyl & Natural Rubber
Backing Binder: PE
Category: Heat Shrinkable Pipeline Coatings
RayJoint is a cross-linked, heat-shrinkable, tubular, all-in-one joint casing. It consists of:
  • Heat-shrinkable, thick wall, radiation cross)linked, high density polyethylene
  • Fiber reinforced, elastomeric mastic sealant


  • Jacket or casing continuation of pre-inuslated pipe systems
  • Permanent sealing of the joint area of insulated pipelines

Features & Benefits:

All-in-one casing requiring no additional end seals No special equipment required
Saves installation steps and materials, thus saving time and money. Makes installation fast and easy, keeps              installation costs low
Excellent thermal stability for storage and transport  Pressure testable prior to foam injection 
Easily survives demanding conditions including high temperatures. very user-friendly & requires no special protection in the field. Assures reliability and optimum performance.
Separately-packed fiber reinforced sealant mastic strips Thick wall crosslinked HDPE material
Prevents contamination of the adhesive bond line. Assures water-tight bond. Extremely resistant to chemical, abrasive, heat & mechanical stress and soil movements. Provides strong, permanent bond.

Max Temperature: 50 ºC, 122 ºF
