Thermofit Tubular Heat Shrink Pipe Sleeves (TPS)

Thermofit Tubular Heat Shrink Pipe Sleeves (TPS)

One-piece heat-shrinkable sleeve for corrosion protection of girth weld joints
on various types of piping systems.

Product Description:

TPS

Construction: two-layer system: 

• First Layer: visco-elastic mastic sealant.
  
• Second Layer: thick-walled, radiation-cross-linked, high density polyethylene.

TPS(M) are heat-shrinkable, tubular sleeves which prevent corrosion of welded pipe joints in distribution lines for sizes up to 8.625"/DN200. For larger sizes, the use of the Raychem wraparound sleeve, WPC, is recommended. This mechanically strong and flexible sleeve is compatible with all standard pipeline coatings and outer jackets.

 The installation is carried out directly on the cleaned and dried (pre-heated) pipe surface without primer. Heat is applied to the sleeve, which shrinks to form a tight fit around the joint. While shrinking, the visco-elastic sealant homogeneously flows to cover the complete surface and fills in all surface irregularities.

 Product Features/Benefits:

• Dimpled backing (TPS) provides a "Permanent Change Indicator" (PCI) for application of heat. Ensures correct application of heat & allows easy post-heat inspection. Reliable inspectability at any time.
• No primer required. Saves installation time.
• Low preheat sensitivity & proven functionality. Allows easy application combined with high functional performance. Saves installation time.
• Mechanically strong & resists abrasion, impact and penetration. Reliable and tough. Remains user-friendly (even at low temperatures).
• Specially formulated sealants. Ensures a strong bond & a tight seal. Provides high peel and shear values after installation.
• Sealing adhesive automatically flows and repairs minor mechanical damages. "Self-healing effect" that saves time.
• No special equipment or skills required. Makes installation fast and easy. Keeps installation costs low.
