A pipe with anti-degradation features used in industrial applications where pipelines carry a liquid with solid particles. The pipe having an abrasion resistant coating to protect the interior surface of the pipe. There being at least one band which is situated inside the pipe for particle collection. The particle collection path is used to collect solid waste that is commonly found mixed with the liquid waste.

Provided are an apparatus for forming non-excavation water and sewage pipe lining for rehabilitation using a textile grid reinforcement material and mortar lining, which allows a textile grid reinforcement material to be continuously disposed and mortar lining to be formed thereon when an old water and sewage pipe is rehabilitated by forming mortar lining in the old water and sewage pipe to fundamentally suppress fine cracks generated on the coated mortar lining, allows the textile grid reinforcement material, to be applied so as to solve a problem of corrosion of the reinforcement material generated when a conventional reinforcing bar or a wire mesh is applied, and in comparison to a conventional method of forming lining of only mortar, allows the textile grid reinforcement material to be applied to reduce a thickness of mortar lining and to perform continuous construction so as to perform economical construction, and a method thereof.

Fouling caused by contaminants onto a metallic tubular, flow conduit or vessel in an underground reservoir or extending from or to an underground reservoir may be inhibited by applying onto the surface of the metallic tubular, flow conduit or vessel a treatment agent comprising a hydrophobic tail and an anchor. The anchor attaches the treatment agent onto the surface of the metallic tubular, flow conduit or vessel.

This corrosion inhibitor can satisfactorily prevent corrosion of the inner surface of a well or pipeline, and contains an inhibitor (A) having a hydrophobic group and a polar group capable of donating an electron pair to a metal surface, an aromatic solvent (B), and hydrophobic nanoparticles (C).
