Provided is an apparatus for coating a girth weld and a cutback region surrounding said girth weld, said apparatus having lateral travel at least equal to the length of the cutback region and circumferential rotational travel around the pipe. The apparatus can provide a multiple component coating accurately and safely, without the need for solvent flushing of the apparatus.

A lateral applicator kit for a pipe has a first application unit and a second application unit that are configured to apply a primer material or other substance to the exterior and interior lateral surfaces of a pipe, respectively. The first application unit is configured to receive primer through a supply engagement feature, which is in fluid communication with a reservoir cavity internal to the first application unit and further in fluid communication with at least one perforated annular wall of an application receptacle configured to receive, and apply primer to, the exterior lateral surface of a pipe. The second application unit is similarly but inversely configured to apply primer to the interior lateral surface of a pipe by receiving primer into a supply receptacle, which is transferred through at least one spout set into and through an annular distributing container connected annularly around the supply receptacle.

A reactor for coating a device is provided. The reactor comprises a hollow body and a port. The hollow body is for supporting the device. The port is in fluid communication with the hollow body for exchanging a coating fluid. In use, the device is moveable within the hollow body from a stacked orientation to an unstacked orientation. Processes for coating devices and systems thereof are also provided.

Described herein is a process for producing insulated pipes including providing a media pipe and a film hose continuously formed from a film or a media pipe and a jacketing pipe, wherein the media pipe is arranged inside the film hose or the jacketing pipe and a slot is formed between the media pipe and the film hose or jacketing pipe, wherein an adhesion promoter is applied to the surface of the media pipe facing the film hose or the jacketing pipe, introducing a polyurethane system at least including an isocyanate component (a) including at least one isocyanate, a polyol component (b), and at least one catalyst into the slot before the adhesion promoter is fully cured, and foaming and curing the polyurethane system. Also described herein are insulated pipes obtainable or obtained by such a process.

In slot-die coating, shrinkage of a PVA film when heating after the application of a PVA solution onto an anchor layer formed on the outer surface of a preform for a plastic bottle is suppressed. A leveling agent such as a siloxane is added to the PVA solution.

A method and system for post-processing of engineered-wood fence pickets or similar fencing components. A post-processing line in the manufacturing factory or facility, or in a post-processing location, includes a special edge-sanding process and apparatus with one or more side sanders to treat the rough edges of the engineered-wood fence picket after sawing. The edge-sanding process produces a smooth side surface on the edges, significantly reduces the number of loose fibers and/or strands, and fills in and/or reduces void spaces. After sanding, the pickets on the belt pass through an apparatus for application of a primer to the processed picket edges. Acutely-angled limited fan sprayers provide complete coverage of the edges with primer at a particular coating thickness required for encapsulation and protection of the fence picket product. The limited fan sprayers may be positioned at varying angles and orientations with respect to the belt and pickets.

Minimum Federal Safety Standards for corrosion control on buried oil & gas pipelines stipulate that metallic pipes should be properly coated and have impressed-current cathodic protection (ICCP) systems in place to control the electrical potential field around a protected pipe. In certain examples described herein, electrically-conductive composites can be used and provide intrinsically-safe materials without the dielectric shielding issues of existing materials used with pipelines. As reacted by customary spray applications, the nanocomposite foams described herein are directly compatible with ICCP functionality wherever foam contacts the metallic pipe. Various compositions and their use with underground and/or above ground pipelines are described.

A surface treatment assembly for treating a contoured surface includes a surface treatment array formed from a plurality of base structures, each base structure operably coupled to a first phalange structure and a first phalange structure first end. A second phalange structure operatively coupled to each first phalange structure and a phalange joint disposed between each first phalange structure and each second phalange, thereby forming a finger structure. Moreover, at least one applicator head is coupled to a second phalange structure second end of each finger structure and configured to treat the contoured surface. A base structure actuator and a phalange joint actuator operatively coupled to and configured to manipulate the first phalange structure and the second phalange of each finger structure to adjust the surface treatment array relative to the contoured surface.

A process and composition for coating a pipe and a pipe support includes mixing a cellulose acetate, a plasticizer, and an oil together so as to form a solid mixture, heating the solid mixture so as to form a liquid state, covering an area of the joinder of the pipe and the pipe support with the liquid state, and drying the liquid state on the area of the joinder. An ethylene-based polymer stabilizer is added to the mixture of the cellulose acetate, the plasticizer and the oil. The oil migrates by gravity from the liquid state from the covered pipe into an area of contact between the pipe and the pipe support. The liquid state is applied around the outer diameter of the pipe and over the outer surface of the pipe support underlying the outer diameter of the pipe.

The present invention deals with a process for producing a coated pipe. The process comprises (i) homopolymerising ethylene or copolymerising ethylene and an -olefin comonomer in a first polymerisation step in the presence of a polymerisation catalyst to produce a first ethylene homo- or copolymer having a density of from 940 to 980 kg/m.sup.3 and a melt flow rate MFR.sub.2 of from 1 to 2000 g/10 min; (ii) homopolymerising ethylene or copolymerising ethylene and an -olefin comonomer in a second polymerisation step in the presence of a first ethylene homo- or copolymer to produce a first ethylene polymer mixture comprising the first ethylene homo- or copolymer and a second ethylene homo- or copolymer, said first ethylene polymer mixture having a density of from 940 to 980 kg/m.sup.3 and a melt flow rate MFR.sub.2 of from 10 to 2000 g/10 min; (iii) copolymerising ethylene and an -olefin comonomer in a third polymerisation step in the presence of the first ethylene polymer mixture to produce a second ethylene polymer mixture comprising the first ethylene polymer mixture and a third ethylene copolymer, said second ethylene polymer mixture having a density of from 915 to 965 kg/m.sup.3, preferably from 930 to 955 kg/m.sup.3 and a melt flow rate MFR.sub.5 of from 0.2 to 10 g/10 min; (iv) providing a pipe having an outer surface layer; (v) applying a coating composition onto the pipe outer surface layer to form a top coat layer, wherein the coating composition comprises the second ethylene polymer mixture.
