Heavy Duty Support & Contact Corrosion Protector

Product Description

Corrosion and deterioration cause many challenges to different types of industries operating under severe outdoor weather conditions.

Industries operating in marine, oil and gas industrial environments, especially located under direct and prolonged exposure to sunlight, rain and saline mildew contributes to extreme corrosion leading to serious consequences. The economic losses of such corrosion and deterioration not only includes cost of replacement but also loss in revenue and penalties due to down time during shut downs.

The areas most susceptible to such corrosion are along pipe supports especially if the supports or pipes are made of metal.

These costly shortcomings and indemnities can be avoided if the pipelines were protected from corrosion with a non-metallic isolator – to isolate the metal and metal contact point

Yes, we have a solution

KON-TAC® acts as a non-metallic corrosion isolator by creating a barrier between pipe and its support structure. KON-TAC® sleeves are available in 1 inch to 24 inches according to pipe’s outer circumference, which form a semi-round segment or can be tailored to Client’s requirements.

At Flosil-BET, KON-TAC are made from high quality composite materials such as Fibre Reinforced Polymer (FRP) or Kevlar and build up with excellent adhesive agent.

FRP are used for KON-TAC with diameter 1 inch to 6 inches, as the Kevlar are used for diameter 8 inches and above.
