Definitions

  • the present invention relates in general to apparatus' and methods of applying liquid coatings onto cylindrical objects, and specifically to pipelines.
  • An illustrative efficacious protective outerwrap comprises a rubber-based adhesive on the pipe surface and an outer tough corrosion and weather-resistance film overlying the adhesive layer.
  • the weather-resistant film is a polyolefinic backing.
  • Pipes intended for inground application are either prepared for inground implantation in the aforementioned manner in a plant or on site. If the preparation is performed in a plant, the pipe is segmented to facilitate transportation and consequently requires joining on site. If the preparation occurs at the site, however, the protective wrap is applied in a continuous uninterrupted fashion. Given the magnitude of pipeline programs, numerous apparatus have been developed to facilitate in-plant or on-site pipewrapping techniques.
  • Such apparatus are multifunctional. Thus, for instance, one may wrap and prime, and in the on site operation given environmental contamination one may clean, prime and wrap.
  • Illustrative of such apparatus is Evans Pipeline Company (CRC) cleaning, priming and wrapping machine.
  • the application techniques vary between in-plant and on-site preparation.
  • in-plant preparation Even application and distribution of primer is easily accomplished by rotating the pipe while applying the primer.
  • the primer can be applied manually or by machine via brushing, spraying or rugging, i.e., saturating a piece of cloth or other absorbent material and applying it to the pipe surface.
  • the apparatus is usually equipped with a piece of material, which moves along behind the primer dispensing means and completely surrounds and is attached to the dispensing means, so as to evenly distribute the dispensed primer onto the pipe surface.
  • Said material is known in the art as a drag sock.
  • the aforementioned apparatus which successfully accomplished an even distribution of primer, is either a free standing machine or is part of a multifunctional machine such as the clean, prime and wrap machines which rapidly advances along the enormous lengths of pipelines.
  • a free standing machine or is part of a multifunctional machine such as the clean, prime and wrap machines which rapidly advances along the enormous lengths of pipelines.
  • such machines are highly successful, their use is limited to pipes which have free ends. This limitation is not problematic with new pipelines, however when reconditioning pipelines, it necessitates a free end and hence mandates stopping the pipeline in operation, making this technique highly undesirable given its economic implications.

  • the cleaning machine is self-propelled for line travel and self-compensating to allow for dents and out-of-ground pipe.
  • the machine comprises opening means which enables one to attach it directly to a midsection of pipe, thereby eliminating the need for a free end.
  • the aforementioned heating machine eliminates the need for segmentation and is fully described in U.S. Patent No. 4,780.158 hereby incorporated by reference, and issued to the present application.
  • Said machine advantageously comprises a pair of semi-circular fuel conduits, thereby eliminating the necessity for a free end.
  • the advantages of being able to apply a pipeline conditioning apparatus midway can be summarily identified as not necessitating interruption of the pipeline operation. In other words,pipelines need not be taken out of operation and disassembled so that a reconditioning apparatus can be placed over a free end and moved along to pipe until the area to be reconditioned is reached.
  • the task of the present invention simply stated is to provide for an evenly distributing liquid coating means which is operable without interrupting pipeline operation.
  • the present invention solves this task in an elegant and efficient fashion by providing for a liquid coating means which comprises hinged preferably extendable conduit sections which allow for encircling of the pipe and hence coating without disrupting pipeline operations.
  • FIG. 1 illustrates the manner of applying the novel circumferential liquid coating means, 10, to an operational pipeline.
  • the novel coating means comprises two conduit sections 12, 12(a) which combined allow for total surrounding of the circumference of the pipe (22).
  • Conduit sections 12 and 12(a) have hinged ends 14 and 14(a) and opposed (distal) closed ends 16 and 16(a) respectively.
  • the hinged ends 14 and 14(a) are provided with central coaxial holes 18 and 18(a) through which an axial pin 20 is positioned to afford a pivot so that the ends 14 and 14(a) are pivotally engaged in order that the opposed ends 16 and 16(a) are free to swing from an open position, thereby enabling the coating means to be placed around the pipe, to a closed position when dispensing coating.
  • the conduit sections 12 and 12(a) may be extendable (not shown). By way of illustration and not limitation, extendability may be accomplished by incorporating a telescoping mechanism into the conduits 12 and 12(a).
  • the conduit sections 12 and 12(a) are each provided with feed arms 24 and 24(a) adjacent their hinged ends for connection to a source of the liquid coating. As shown, the feed arms 24 and 24(a) are connected to the leading ends 26 and 26(a) of a bifurcated hose, 28, the trailing end of which (not shown) is connected to a liquid supply source (also not shown).
  • the liquid coating may be fed into the hose 28 by per se known means, e.g. pumping means, gravity feed or the like.
  • a shut-off valve 30 of per se known construction is provided to control delivery of the liquid coating material.
  • spacing means may be provided at spaced intervals along the inner surface of the sections 12 and 12(a).
  • the spacing means consist of one or more roller (s) (not shown) which advantageously facilitate uniform application as well as pipeline travel along the pipe during operation.
  • said spacing means may be adjustable so as to be employed with varying pipe diameters.
  • the conduits 12, 12a are provided with a plurality of apertures 12, which may be uniformly spaced along the inner surface of the arcuate segments 12 and 12(a).
  • the segment 12 may have one centrally disposed aperture, which in operation dispenses a coating from atop the pipe and the coating is evenly distributed by use of gravitational force.
  • the coating is even more evenly distributed than by the use of gravitational force.
  • a sock (not shown) which may be attached to one or both segments 12 and 12(a) in a manner which allows for it dragging behind the line on which the coating means 10 travels while dispensing liquid coating material.
  • coating means, 10 may be mounted on a movable base (not shown), such as rollers, conveyor belt or tracks, etc., to facilitate pipeline travel.
  • the coating means 10 may be joined with the novel heating means disclosed in U.S. Patent No. 4,780,158 issued to the present applicant and/or other pipeline conditioning machines to allow for a complete reconditioning unit which is functional without disrupting the pipeline operation.
