    摘要： A method for coating an inner surface of a metal tube comprises supplying a hot-melt resin powdery paint floating in air together with an air stream into the metal tube which has been pre-heated and rotating around it's horizontal center axis. An apparatus used for the method comprises a rotating means for supporting and rotating the metal tube, fluidizing bed tank for floating the powdery paint in air, a paint supply pipe, an air pipe and a Y-shaped mixing pipe through which the powdery paint is supplied to the inside of the metal tube in the form of a jet. The inner surface of the metal tube can be coated uniformly in a very short period of time.

    摘要： A method of powder coating the inside of tubular goods, such as oilfield pipe and the like, by connecting one end of the pipe to a means for producing a flow of compressible gases therethrough. The other end of the pipe is open to atmospheric pressure. A valve means is connected for controlling the flow of air through the container which holds a single charge of plastic powder. The charge of powdered plastic is isolated upstream of the pipe inlet. The charge is of sufficient size to coat the entire inside peripheral wall surface of the pipe with a substantial uniform coating of plastic. The pipe is heated above the softening temperature of the plastic and axially rotated, so that when the valve is opened, air flows through the container, into the pipe, and establishes a pressure gradient across the entire length of the pipe. This action causes the captured charge of plastic to form a pocket of dispersed plastic particles which is forced to flow through the pipe by the air flow. The plastic particles are deposited and fused to the hot rotating inner surface of the pipe.

    摘要： The difficulty of applying uniform plastic coatings to the interior of pipe and other tubular goods increases in proportion to the diameter and length of the pipe. Epoxy is one of the most satisfactory plastic coatings for use on oilfield pipe. An epoxy coating preferably is applied on powdered form to the heated, rotating pipe interior, where the plastic is fused into a continuous film and thereafter the pipe is cooled as the film solidifies to provide a superior coating which protects the metal pipe surface from chemically reacting with the material flowing therethrough, thereby elongating the life of the pipe.

    摘要： Methods and systems comprising a first and a second powder coating apparatus, with each apparatus comprising a tubular barrel having an axial bore extending longitudinally therethrough, are usable for coating an interior surface of a tubular member. Each coating apparatus comprises a conical member connected with the tubular barrel and at least one gas conduit connected to the tubular barrel for communicating gas into the tubular barrel. The at least one gas conduit contains a gas flow control valve connected thereto for controlling the volumetric flow rate of gas through the at least one gas conduit. Each coating apparatus further comprises at least one container for holding a coating material, an inlet conduit for communicating the coating material into the axial bore of the tubular barrel, and a plurality of gas nozzles connected to the tubular barrel for inducing spiraling gas flow through the axial bore of the tubular barrel.
