This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with an outer wrap. In one embodiment, a pipe includes an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. The pipe also includes an outer wrap applied to the outer wall. The outer wrap may include fibers and plastic. The outer wrap may span the corrugation crests producing a smooth outer surface.

Pipe with an outer wrap

A method for installing a liquid quality system into a containment structure, wherein the liquid quality system includes a liquid quality device and at least one drag-inducing assembly, wherein the at least one drag-inducing assembly includes at least one supporting portion and at least one drag-inducing portion, wherein when the liquid quality device is installed a sump region is formed below, is provided. The method may include mounting, at least partially in the sump region, the at least one supporting portion onto a sidewall of the containment structure. The method may also include attaching the at least one drag-inducing portion to the at least one supporting portion. The method may also include mounting the liquid quality device in the containment structure.

Method for installing a liquid quality system

A liquid quality system for removing particulates from liquid (e.g., storm-water runoff). The system can include tubular portion (e.g., a manhole). The tubular portion has an inlet and an outlet. The system includes liquid quality device. The liquid quality device includes a partitioning portion. The partitioning portion has a first region including a funnel shape with a sump inlet aperture. The partitioning portion also has a second region including a sump outlet aperture and optionally a sump access aperture. A sump region is located between a base portion and the partitioning portion, wherein a flow of the liquid travels from the inlet in the tubular portion, into the funnel, through the sump inlet aperture, into the sump region, through the sump outlet aperture, and out the outlet of the tubular portion. At least one drag-inducing portion is positioned proximate the tubular portion in the sump region and projecting inwardly towards a central axis of the sump region.

Liquid quality system with drag inducing portions

The embodiments of the present disclosure provide a method of applying an outer wrap to a corrugated pipe. The method comprises receiving a corrugated pipe that is cut to length, determining a wrap type to be applied to the corrugated pipe, determining a flow rate for applying a wrap of the wrap type based on a type of plastic used in the wrap, a type of fiber used in the wrap, and the wrap type, and applying a wrap made of the type of fiber and the type of plastic to the corrugated pipe using the determined flow rate.

A method of welding a gasket to a spigot portion of a pipe section is described. 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.

Methods and assemblies for welding a gasket to a pipe section

This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with a reinforcing stiffener. The corrugated pipe may include an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. In some embodiments, a stiffener may be positioned within the corrugation valleys. In other embodiments, a stiffener may be positioned within the corrugation crests.

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.

Systems and methods for coupling pipe with angled coupling mechanism

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.

A corrugated pipehas a plurality of corrugation structurespositioned adjacent one another. The corrugation structurescomprise an inner cylindrical wall, two annular wall portionsthat extend outwardly from the inner cylindrical wall, and a bowed annular wall portionthat is connected to the outer endsof the two annular wall portions. The corrugation structureincludes a centroidand at least a portion of the inner surfaceof the bowed wall portionhas a radius Rcentered on the centroidand at least a portion of the outer surfaceof the bowed wall portionhas a radius Rcentered on the centroid. The cavitydefined by the corrugation structurehas an inner surface with an inner radius R, Rthat is equal to or greater than one half the thickness Tof the inner cylindrical wall. The profile of the corrugation structureis configured to optimally accept forces caused by backfill soil positioned over the pipe. A method of manufacturing a corrugated pipeincludes manufacturing a first, a second, and a third corrugated pipe, with each pipe having an inner diameter ID and an outer diameter OD. The inner diameter ID is chosen such that the first pipecan be telescopically inserted into the second pipeand the second pipecan be telescopically inserted into the third pipe. A method of shipping a plurality of different diameter pipes is also provided.
