    Abstract: A pipe coupling for coupling adjacent ends of a pair of pipes includes a sleeve, a split-ring gland positioned around one of the ends of the sleeve, and at least one annular gasket positioned within the split-ring gland and configured to be compressed by the split-ring gland for sealing one pipe end to the sleeve. The split-ring gland includes two partially circular gland members with spaced ends defining a gap, and abutting ends configured to be bolted together via apertures tangential to the gland members so as to avoid outward scissoring.

  • Publication number: 20130009395
    Abstract: A coupler utilizes a conventional sanitary clamp member 12 having a handle 14 releasably clamping first and second halves 16 and 18 together. The inner surface of halves 16 and 18 is provided with a groove 20 having angled sides 20a and 20b which serve to axially press together male 22 and female 28 members together as handle 14 is tightened. Male member 22 has a generally cylindrical plug 24 with end 30 which extends into socket 28b of female member 28. An O-ring 26 is located on the circumference of plug 24 and seals against the inner cylindrical surface of socket 28b.

  • Publication number: 20120273474
    Abstract: The present invention relates to a connecting apparatus used for connecting underground pipes and to a composition for preparing a foamed sheet for the same. Specifically, the present invention relates to a sheet composition for pipe connection which comprises 1 to 10 parts by weight of a masterbatch including low-density polyethylene, high-density polyethylene, a maleic anhydride graft copolymer, a metallocene polyethylene elastomer, a foaming agent, and an additive, based on 100 parts by weight of a base resin including low-density polyethylene, high-density polyethylene, a maleic anhydride graft copolymer, and a metallocene polyethylene elastomer. When using the composition according to the present invention, a non-foamed sheet is produced during melt extrusion, and a foamed sheet is obtained at a high temperature by laminating the non-foamed sheet with a heater line and applying electricity thereto. Therefore, the sheet composition can be fused and filled into a pipe.

  • Publication number: 20120256415
    Abstract: A coupling for securing pipe elements together in end-to-end relation has segments joined at one end by a pivot attachment and at an opposite end by an adjustable connection member. The segments surround a central space which receives the pipe elements. A gripping body is captured between the segments. The segments have angularly oriented reaction surfaces. The gripping body has angularly oriented contact surfaces which interface with the reaction surfaces. When the segments are drawn toward each other by the connection members, interaction between the reaction surfaces and the contact surfaces forces the gripping body radially inwardly. Inwardly facing arcuate surfaces on the segments and the gripping body engage and retain the pipe elements. A method of inserting pipe elements into the coupling while the segments and the gripping body are supported on a seal is also disclosed.

  • Publication number: 20120242083
    Abstract: A pipe coupling that clamps onto an area adjacent the ends of abutting pipes. The pipe coupling includes first and second clamp members, and a fastener. The first clamp member is hinged to the second clamp member. Both the first and second clamp members are configured to pivotally wrap around a pipe. Each of the first and second clamp members also includes an arched hub portion configured such that when each of the clamp members engages each other the arched hub portions form an arcuate hub. The fastener is configured to couple the arched hub portions together thereby preventing the clamp members from opening.
