A lining for a compressor case is provided. The lining comprises a layer of primer applied to an interior surface of the compressor case, and at least one layer of a seal compound applied to the layer of primer. The primer has been found to significantly improve the bond strength between the base metal and the coating. Also, the primer provides a waterproof coating at the bond interface, which prevents any moisture from creeping under the plastic and causing material break-out. The waterproof coating also provides an increased corrosion resistance to the base metal and stator vanes where the plastic lining has been applied. A method of lining a compressor case is also provided, comprising applying a first layer comprising a primer to an interior surface of the compressor case, and applying at least one second layer over the first layer of primer, the at least one second layer comprising a seal compound to line the compressor case.

A method for coating a pipe involves applying a coating material of cellular structured extruded thermoplastic material to the pipe and enclosing it on the outside by an outer covering layer of compact plastic. In an extrusion head, the annular opening for supplying coating material can be adjusted to a desired temperature by a region having coolant channels separated from the annular opening by an annular heat exchange surface. Before being applied to the pipe, the flowable coating material is guided along the heat exchange surface and cooled to a temperature just above the solidification temperature thereof. After the coating material leaves the annular opening, the coating material expands in a controlled manner, widening the outer covering layer depending on the adjusted temperature of the coating material, until the coating material begins to solidify. The outer covering layer surface condition can correspond to or be different from the pipe.

Coating compositions for coating an oilfield operational component, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of the oilfield operational component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

Example embodiments relate to a method of protecting a surface of an e-vaping device portion from corrosion, the method including preparing a coating mixture configured to protect the surface from corrosion, and coating the surface with a protective coating based on the coating mixture, wherein the coating is performed via one of electrodeposition, dipping, spraying, and vapor deposition, and the coating mixture includes at least one of a silane and a resin.

A resin coating layer according to the present invention is formed by curing a thermo-setting resin composition on an inner wall of a heat transfer tube. Forming the resin coating layer allows the heat transfer tube to be easily repaired without involving a cutting process of the heat transfer tube.

An open tubular chromatography apparatus has at least one liquid chromatography capillary, a valve in fluid communication with the liquid chromatography capillary for adding a sample to the liquid chromatography capillary, an injector in fluid communication with the valve for driving liquid eluent through the liquid chromatography capillary whereby components of the sample are separated in the eluent, and one or more detectors for detecting the components in the sample as the components elute from the liquid chromatography capillary. The liquid chromatography capillary has an inner surface and an inner diameter in a range of from about 1 m to about 5 m. The inner surface is coated with a stationary phase film.

A spinner apparatus for applying lining material to the interior of a pipe, the spinner apparatus having a cylindrical material accelerator coaxially positioned about a distribution manifold, the distribution manifold having a plurality of equally spaced, radially oriented slots extending from an axial chamber that receives lining material, wherein lining material is extruded through the slots onto the interior of the material accelerator and slung onto the pipe interior in an annular pattern. Movement of the spinner apparatus along the pipe produces a tubular lining member.
