Cheray Polymer type HMS Composite 3C

Product description:

Viscoelastic-Mastic Composite Configuration Coating Sleeve (3CS) is the latest product specially designed and developed by Cheray Polymer CO., aim at pipeline field joint corrosion protection technology trend and client actual requirement. It completely solves various application defect of common heat shrinkable wraparound sleeve, such as complicated installation technological requirements, longer installation time, unstable manual installation quality and unsatisfied corrosion protection long term performance.

HMS Composite 3C heat shrinkable sleeve is composited adhesive configuration with 2 layers.

Cheray Polymer type HMS Composite 3C structure system:

First layer: viscoelastic adhesive and mastic adhesive composite configuration Viscoelastic adhesive coated on the central part of sleeve, mastic adhesive coated on the two side parts like a belt along the sleeve radial direction, two type of adhesive seamless connect
Second layer: radiation cross-linked high density polyethylene

The coating meets the requirements of the following standards:

EN 12068:2002 – C 50
ISO 21809-3:2016, Type 13B-3

Advantages and features of the system:

Does not require the application of epoxy primer – time saving!
Steel pipeline surface preparation just meet ST2.0 ~ ST3.0, get rid of humidity absorbed water on steel surface is enough
The ability to self-regenerate and disappear air spaces under the material
Easy application at low temperatures, minimum application surface temperature +50°C
Minimum grade SP 2 for surface preparation (wire brush)
Closure patch is pre-installed – save time
Installation process is same with common heat shrinkable sleeve, post heating is not necessary after shrunk
Installation can be done under ambient temperature -40℃
Easy learn and operate
Easy field installation, saves time & cost, much save construction and maintenance cost
Excellent corrosion protection long term performance
3C heat shrinkable wraparound sleeve is compatible to girth weld field joint coatings such PE, PP, FBE and PU, also for pipe bend, pipe elbow, fitting and coating repair
