    摘要: Lengths of polymer-coated tubing are continuously produced from steel strip by roll-forming and welding at a fast rate of speed. The welded tubing is sized, cleaned and heated to raise its temperature to that desired for applying a polymeric coating. After coating, the tubing is heated to a desired baking temperature and then cooled. The tubing is unsupported from a location upstream of the coating station until cooled. Elongated endless belts grip the tubing over a longitudinal distance of at least about 2 feet and pull the tubing in a controlled manner to maintain the tubing in precise spatial location throughout its heating, coating and baking.

    摘要: A PROCESS FOR APPLYING A COATING TO A METAL STRIP WHEREBY THE METAL STRIP IS FIRST PRE-TREATED TO CONDITION IT FOR APPLICATION OF THE COATING, AFTER WHICH THE COATING IS APPLIED TO EITHER ONE OR BOTH SIDES OF THE STRIP. THEREAFTER, THE COATED STRIP PASSES THROUGH A HEATING STATION WHERE IT IS HEATED BY MEANS OF ELECTROMAGNETIC INDUCTION. A HOOD SURROUNDS THE INDUCTION HEATING MEANS SO THAT THE VAPORIZED SOLVENTS AND OTHER FUMES ARE PREVENTED FROM PASSING INTO THE ATMOSPHERE AND OVER THE COATED METAL STRIP DOWNSTREAM OF THE HEATING STATION. A HOOD IS PROVIDED WITH CONDENSING MEANS TO CONDENSE THE VAPORIZED SOLVENTS AND TO PERMIT RECOVERY OF THE CONDENSED SOLVENTS, AND IS ALSO PROVIDED WITH AN AFTERBURNER TO BURN UP ANY UNCONDENSED VAPORS OR GASES TO PREVENT CONTAMINATION OF THE ATMOSPHERE. A SERIES OF COOLED ROLLERS ARE PROVIDED DOWNSTREAM OF THE HEATING MEANS TO NOT ONLY ACT AS CONVEYORS FOR THE STRIP, BUT ALSO AS PROGESSIVE COOLING MEANS TO COMPLETE THE CURE OF THE COATING.

    摘要: 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.
