Details:
Polyolefin anti-corrosion inner-layer tape

System description:

 

The XUNDA-T-100 series is Cold applied tape coating system for corrosion protection of Oil, Gas, Petrochemical, and 
Waste Water underground or overhead pipelines.

 

The inner layer tape shall be applied after the Liquid adhesive and before the middle layer tape by wrapping machine 

 

ⅡStructure:

The specification of the tape consists of two layers, adhesive layer and film backing 

 

AdhesiveButyl rubber 

Film backingSpecial blend of stabilized polyolefin 

Ⅲ Features:

Excellent adhesion to pipe and self 

Can be applied over a wide temperature range 

Good conformability and consistent uniform thickness 

Easily applied with no special equipment 

Compatible with common pipe coatings 

Excellent resistance to cathodic disbanding 

Meets AWWA C 214 Standard 

Cold applied

XUNDA TAPE SERVES FOR

Oil, Gas and Water Transmission pipeline market
Oil and Gas distribution and utility markets
New pipeline construction markets
Rehabilitation and Reconditioning market
Offshore Industry
Refinery and Petrochemical Plant Industry
Manufacture of Polyethylene coatings utilizing Butyl based elastomeric adhesives,
Polyethylene films and liquid adhesives for corrosion protection of steel pipe.
Provides corrosion protection with the inherent chemistry of Polyethylene and Butyl
Adhesive for resistance to water and oxygen penetration. Oxygen and Water are prevented
 from reaching the metal substrate, which are necessary and sufficient conditions for corrosion.
Manufacture of conventional and specialty Polyethylene, Polypropylene and Polymeric Alloys and
coating systems for pipe corrosion protection.
Manufactures PE coatings systems for applications for New Pipe Construction and
Rehabilitation and Reconditioning
Approved to ISO 9001 and to other good manufacturing and technical standards and norms
governed within the energy and pipeline industry.
Coating systems that have a broad range of temperature and shear resistance properties
to meet the requirements of the pipeline and end-user.
