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 device for staining or painting planks has an enclosure and a plank receiver for guiding a plank into the enclosure. At least one pair of vertical rollers are provided for engaging the plank received in the plank receiver. A lever may be positioned to contact the plank upon exit from the plank receiver. A linkage bar is affixed to the lever and to vertical rollers. Moving the lever by insertion of the plank moves the vertical rollers in preparation for receiving a leading edge of the plank. The vertical rollers are mounted on swing arms for facilitating adjustment of a space between the left vertical rollers and the right vertical rollers for accommodating planks of various thicknesses. Vertical sprayers are pivotally mounted and in communication with the swing arms for pivoting with the vertical rollers for maintaining a constant distance between the vertical rollers and the left vertical sprayer.

A flame coating machine for coating field joints of a pipeline has a flame spray system having two flame spray units configured for heating and/or coating with a thermoplastic polymer an annular junction portion and two annular end portions of an existing coating delimiting the annular junction portion; a control system having two temperature sensors configured for acquiring temperature values along the surface collectively defined by the annular junction portion and the annular end portions, and a control unit configured for actuating the flame spray unit in a polymer flame spraying mode or in a flame heating mode as a function of the detected temperature values and at least one threshold value.

A plurality of sliding rails and a frame structure comprising a plurality of frame elements configured to be arranged at least partly circumferentially around a tower structure. Each frame element is slidably connected to at least one of the sliding rails, and the frame elements and the sliding rails are interconnected to form a scissor structure. An upwardly directed lifting force applied by a hoisting mechanism at connecting points at or near positions where the frame elements are connected to the sliding rails, in combination with gravity working on the frame structure, causes the frame elements to slide along the sliding rails, thereby causing the scissor structure to contract or expand to adjust a diameter of the frame structure to an outer diameter of the tower structure having the apparatus mounted thereon.

A holder, a transport device, and a method of manufacturing a container are described. The container comprises a body that extends along an axis and a flange that extends radially to the axis, and the holder comprises one or more fastening elements that are configured to engage one or more of a top surface, a bottom surface, or a peripheral surface of the flange.

A vehicle axle galvanizing device is disclosed. A driving clamping unit having a hydraulic chuck installed therein and a driven clamping unit clamp an axle. A dust collection case, configured to accommodate a part to be galvanized of the axle, and cooling cases, configured to accommodate heat-treated bearing joints, are closed. The axle is rotated by a motor in the driving clamping unit, and cold air generated by a cooling unit is continuously sprayed on the heat-treated bearing joints through cooling guns respectively fixed to the cooling cases. Further, in this state, an industrial robot is operated to allow a spray gun in a zinc spray unit to enter the inside of the dust collection case, and zinc melted by the zinc spray unit is sprayed on the part to be galvanized, thereby forming a galvanized layer thereon.

An applicator machine and a process for heating and coating a section of pipeline. The applicator machine includes a frame configured to rotate about a section of pipeline to be heated and coated, rotating means operable to rotate the frame, and coating material applicators induction coils and radiant heaters mounted on the frame and rotatable therewith. The induction coil is configured to heat a section of pipeline adjacent to the induction coil to a coating material application temperature. The radiant heaters are configured to heat factory-applied coatings. Each coating material applicator sprays coating material through an aperture in a respective induction coil. The applicator includes an enclosure configured to surround a section of pipeline and provision for evacuating and collecting waste coating material. The coating material applicator may be configured to spray powder coating material, such as fusion bonded epoxy powder material and/or chemically modified polypropylene powder material.

A machine for making a protective joint has a guide system, which is selectively clampable about a pipeline on opposite sides with respect to the annular junction portion and configured for defining an annular path about the annular junction portion; at least one heating unit moveable along the annular path and configured for heating the annular junction portion and moveable along the annular path; at least one spray unit moveable along the annular path and configured for applying at least one polymer material to the annular junction portion; and an extrusion die moveable along the annular path and configured for applying a protective foil about the annular junction portion.
