Abstract
The disclosure relates to improved gel/grease compositions as well as grease compositions capable of imparting improved corrosion resistance. The grease includes a silica/silicate mixture that can imparts a relatively high pH and corrosion resistant properties to the grease.
Claims14
A corrosion resistant and insulated pipe comprising:
- at least one pipe,
- at least a portion of said at least one pipe is coated with a corrosion resistant gel coming a combination comprising at lest one synthetic oil and at least one silicate, and;
- insulation at least partially in contact with said corrosion resistant gel and extending around said pipe.
An insulated pipe comprising at least one pipe and insulation positioned around said pipe wherein a composition comprising a combination comprising at least one synthetic oil and at least one silicate is located between said at least one pipe and the insulation.
Insulation for a pipe comprising at least one insulating material and a corrosion resistant composition applied onto a least a portion of the insulating material wherein the composition comprises a combination comprising at least one synthetic oil and at least thickener.
A method for increasing the corrosion resistance of insulated pipelines comprising:
- providing a metallic pipeline,
- applying a composition, comprising at least one synthetic base oil and at least one silicate, onto the pipeline, and
- applying insulation around the pipeline and upon the composition.
