20150136255 | PIPE HAVING SLITS - A pipe is disclosed. The pipe may comprise an inner wall, an outer wall coupled to the inner wall and including a plurality of corrugation crests and a plurality of corrugation valleys, and a plurality of slits positioned within the corrugation valleys, wherein the slits may be evenly spaced relative to each other around an entire circumference of the pipe. | 05-21-2015 |
20140174653 | METHODS AND ASSEMBLIES FOR WELDING A GASKET TO A PIPE SECTION - The present disclosure is directed to a method of welding a gasket to a spigot portion of a pipe section. The method includes supporting the gasket in a recess on the spigot portion of the pipe section. The gasket includes a seating portion and a sealing portion. The sealing portion includes a first shoulder portion and a second shoulder portion. A first bonding portion extends from the first shoulder portion and a second bonding portion extends from the second shoulder portion. The first bonding portion and the second bonding portion are provided to bond the gasket to the spigot portion. The method further includes heating a portion of the gasket and an adjacent surface of the spigot portion and applying a force onto the portion of the gasket following the application of heat to fuse the gasket onto the spigot portion. | 06-26-2014 |
20130134705 | Systems And Methods For Coupling Pipe With Angled Coupling Mechanism - Embodiments of the present disclosure include a coupling mechanism. The coupling mechanism may include a connection section including a first opening, an inner flange, and an outer flange, wherein the connection section is configured to connect to a first pipe, a sleeve portion including a second opening and configured to connect to a second pipe, and a channel extending through the coupling mechanism between the first opening and the second opening, wherein the first opening is angled relative to the second opening, wherein the inner flange includes a first end and a second end, wherein the first end of the inner flange includes a width larger than a width of the second end of the inner flange. | 05-30-2013 |
20110200391 | Stormwater containment assembly and associated end section - An end section or cap for a stormwater containment assembly includes a substantially half-dome-shaped body member and a connector disposed on the body member along a periphery or perimeter thereof, for coupling the body member to a stormwater chamber wall. The body member has a smooth convex outer surface with an absence of reinforcement ribs and also has a smooth concave inner surface with an absence of reinforcement ribs. | 08-18-2011 |
20090075004 | APPARATUS AND METHODS FOR CROSS-LINKED CORRUGATED POLYETHYLENE PIPE - A composition and method for a single or dual wall extruded and thermoformed pipe corrugated HDPE pipe composed of a thermoplastic HDPE that is subsequently cross-linked by introducing moisture. The typical thermoplastic HDPE utilized for blow molding to fabricate the corrugated pipe is cross-linked to enhance dimensional stability, stress crack resistance, impact, creep resistance, and stiffness. The method also may comprise obtaining the enhanced properties by cross-linking the already fabricated linear HDPE corrugated pipe. The cross-linked HDPE is produced using a silane processing method. A composition may comprise a high density polyethylene compound composed with about 1 to 15 percent of finely ground isotropic cross-linked polyethylene recycle. | 03-19-2009 |
