    摘要: An elongate electrode, usually an anode, is provided, suitable for use in an impressed current corrosion protection system. The electrode comprises a central elongate core, usually a metal such as copper, an optional conductive polymeric composition surrounding the metal core and having a higher electrical resistivity than the core, but being in electrical contact with the core, a flexible jacket, for example, a fabric braid containing within it particulate coke, and tensioning wraps positioned around the flexible jacket. The purpose of the tensioning wraps is to compact the coke particles relative to their compaction in the absence of the tensioning wraps.

    摘要: A protector for a segmented anode encircles a pipeline. The protector includes an elastomeric polymeric structure molded in place at each end of the anode. The structure has the external shape of the frustrum of a cone with the base of the cone encircling the tapered end of the anode. The frustrum terminates at the diameter of the pipeline. The taper is made from a tough, fast setting polymer. In a preferred embodiment the polymer not only forms the molded taper, but fills the space between the anode segments and flows between the anode segments and the pipe. The protector adheres to the pipe as well as to the anode material, provides a corrosion barrier, and bonds the anode segments to the pipe.

    摘要: A clamping collar includes a clamping collar body extending along a longitudinal axis and having at least two clamping collar shells with side walls. At least one clamping receiving space is defined by the side walls of the collar shells for receiving and retaining a pipe in the space along the longitudinal axis. At least one recess in the side walls opens radially inwardly into the receiving space and extends axially parallel to the longitudinal axis. The recess is open to an atmosphere exteriorly of the collar body at at least one axial end of the recess.

    摘要: An anti-corrosion sealing assembly for use between a protective casement sleeve and a pipe to be protected is disclosed. The pipe extends through the protective casement sleeve such that an annular casement cavity is formed therebetween. The sealing assembly includes a muff arrangement secured between outer surface portions of the casement sleeve and the pipe at each end of the casement sleeve. More particularly, inner and outer muffs are secured about outer perimeter portions of the pipe and the casement sleeve at each end of the casement sleeve such that the outer muff totally encompasses the inner muff thereby forming a mold cavity therebetween. Each outer muff further includes a pouring spout into which a sealing compound may be poured. Furthermore, an injection tube extends through the inner and outer muffs and opens into the annular casement cavity to permit a corrosion inhibitor to be injected therein.

    摘要: A method of applying corrosion resistant liners to the structural steel walls of flue gas lines, flue gas treating apparatus, scrubbers and the like. The wall to be protected is provided with spaced apart bores and the liner sheets are applied to the inner surface of the structural steel wall. The studs are joined to the sheets by stud welding and the sheets are then drawn tightly against the wall by the application of tensile forces to the studs. The studs are subsequently gas tightly joined to the wall, e.g. by welds. An alternative method of attachment uses a screw thread on the stud and the nut which is threaded onto the stud and bears against a washer and a sealing ring which is pressed against the wall around the stud.

    摘要: In a pipeline road crossing a pipeline is loosely surrounded by a casing under the roadbed with its ends vented to the atmosphere and sealed with the periphery of the pipeline to minimize oxidation of the pipeline wall within the casing. Access and pressure relief valves are connected with the casing vents at opposite sides of the road. This permits injecting gas under pressure into the casing annulus through the valve equipped vents and periodically monitoring the gas pressure.

    摘要: A sleeve, which finds particular application in the environmental sealing of joints between insulated pipes, comprises heat-recoverable polymeric sheet material provided at separate regions of a principle surface thereof with a layer of a heat-activatable adhesive for bonding the sheet to the pipe insulation, and a layer of a sealant to accommodate flexibility in the joint. A layer of a sealing material, having an elongation modulus greater than that of the sealant, overlies at least part of the sealant layer, to improve the pressure retention properties of the sleeve.

    摘要: A flange connection of pipe pieces having an outer layer composed of a laminate and provided with grooves. A two-part sleeved collar of the same material is radially placed onto the pipe piece. Projections provided on the radially inner surface of the flanged sleeve are placed in the grooves. The two parts of the flanged sleeve are fixedly connected to the pipe pieces by means of gluing, the two parts of the flanged sleeve being held together until the adhesive has cured by means of a flange ring slid onto a conical portion of the flanged sleeve. A cover ring is fastened to the end of the inner layer of the pipe piece made of a thermoplastic material, so that the medium conducted through the pipes does not come into contact with the couter layer and the flanged sleeve.
