Creep The ability of a material to resist movement under resistance pressure.

Cutback The area from the weld seam on a field joint to the leading edge of the mill applied coating.

Elastic Memory The ability of a heat-shrinkable sleeve to return to its original size after heat has been applied.

Elastomer Any one of a family of materials of both natural or synthetic origin, which possesses rubber-like characteristics.

Elongation The amount of stretch in a strip of material, measured under controlled conditions. The amount of stretch at the point of break is expressed in percentage.

Galvanic Cell A cell in which chemical change is the source of electric energy. It usually consists of two dissimilar conductors in contact with each other and with an electrolyte, or two similar conductors in contact with each other and with dissimilar electrolytes.

High Shrink Sleeves Heat-shrinkable, corrosion protection and sealing sleeves for high profile (flanges, couplings, tytons, etc) joints.

Holiday A discontinuity of a coating that exposes the metal surface to the environment.

Holiday Detector Device used to detect areas of the pipe which are not being protected by a coating.

Hot Melt Adhesives A family of adhesives based on semi-crystalline polymers characterized by very high shear strengths and often high peel strengths.

Impact Resistance The resistance of a heat-shrinkable sleeve to break when a sudden dynamic force is applied.

Layflat Length The length a wraparound sleeve must be cut to in order for it to fit a specific diameter pipe.

Mastic Pour (also called 'MARINE MASTIC POUR', OR 'HOT POUR') application of a molten (375°F - 400°F) mastic in the field joint annulus of a concrete coated pipe usually on a lay barge. The joint protection method chosen must be able to withstand these extreme temperatures.

Mastics (Also called 'SEALANTS') A family of adhesives based on butyl rubber, polyisobutylene, synthetic rubbers, and asphalts. Mastics are amorphous, pressure sensitive, and tacky, so they bond easily to substrates upon contact and pressure.

Moisture Resistance The resistance of a heat-shrinkable sleeve of the passage or the absorption of moisture, or to the harmful affects of moisture.

Moisture Vapor Transmission Rate A test by which the weight of water vapor transmission through a heat-shrinkable sleeve is measured in grams per hundred square inches per 24 hours.

Offshore Sleeves Heat-shrinkable, girth-weld corrosion protection and sealing sleeves for subsea pipelines.

Penetration Resistance A heat-shrinkable sleeve's ability to withstand high pressure on a small area for a period of time without puncturing.

Pipeline Repair Products Heat-activated patches, melt-sticks and fillers for mainline coating repairs.

Rehab Sleeves A family of heat-shrinkable, corrosion protection sleeves for the rehabilitation of existing pipelines.

Release Liner A paper or plastic sheet affixed to the adhesive for protection during handling and storage. It is removed and discarded before application. Sometimes called a 'LINER'.

Salt Crock Test A test which measures the amount of disbondment which occurs on a coating in a salt solution which has electricity passing through it.

Shear Strength The resistance of a heat-shrinkable sleeve to shearing when a load is applied along the plane of the sleeve.

Solvent Resistance The resistance of a backing or adhesive to dissolving in an organic solvent or soils containing such solvents.

Stabilizer A chemical added to prolong the life of a material, such as a stabilizer added to a polyethylene backing which enables the backing to resist the deteriorating effects of ultraviolet light.

Superseal™ A family of heat-shrinkable, sealing sleeves for the jacket pipe continuation of pre-insulated pipes.

SuperCase A family of heat-shrinkable, casings for the jacket pipe continuation of pre-insulated pipes.
