Abstract:
A structural component for use in oil, gas, exploration, refining and petrochemical applications in the form of a pipe system is provided. The structural component comprises a plurality of layers, a structural layer comprising a composite material; a corrosion resistant layer for contacting the corrosive petroleum products, the corrosion resistant layer comprising a ceramic material; a fire resistive layer having a thermal conductivity of less than 0.4 W/m° C. In one embodiment, the structural component has a burn-through time of greater than 5 minutes. In another embodiment, the structural component meets level II fire endurance standard according to IMO A 18/Res.753 fire testing protocol.
Abstract:
The present invention is directed to ceramic fiber insulation and related products and methods. A coating that is capable of being brushed and/or sprayed lightly as a liquid onto vacuum-formed ceramic fiber insulation for use at high temperatures is also provided.
Abstract:
A method of corrosion inhibition using a gelled inhibitor is disclosed. The method comprises consecutively introducing into an annular region of a jacketed pipeline a hydrogel slurried in an environmentally innocuous oil medium and a corrosion inhibitor dissolved in an aqueous medium. The liquid media are contacted to form a gelled corrosion inhibitor in the annulus. The method is particularly useful in buried pipelines where corrosion monitoring is difficult.
Abstract:
A pipe section of an outer metallic pipe and a nonmetallic inner lining is provided so that the lining can be removed. To this end, the lining consists of lining segments, the terminal members of which are braced against the ends of the pipe in a form fitting manner and the successive lining segments can interfit with, for example, complementary frustoconical formations.
