Fiberkev™ is a heat-resistant para-aramid synthetic fiber with a molecular structure of many inter-chain bonds that make it incredibly strong. Has many applications because of its high tensile strength-to-weight ratio.

Fiberkev™ uses Kevlar®* one of the strongest and most versatile textiles, boasting a tensile strength-to-weight ratio so high, it is five times stronger than steel. Kevlar is a synthetic material that is, to put it simply, a very strong woven plastic

Main Features

COMPOSITE REPAIRS: Provides permanent protection in the harshest conditions. It was formulated for the special conditions found on the internal and external surfaces of oilfield production tubulars, oil and gas separators or similar equipment. This equipment is critical to production and is often exposed to a fast-moving stream of crude hydrocarbon typically containing sulfur acids, brine and entrained sand. When this current encounter bends or surface irregularities such as sharp welds, it can cause rapid erosion leading to failure.
