Systems and methods for efficiently managing bulk material are provided. The disclosure is directed to a portable support structure used to receive one or more portable containers of bulk material and output bulk material from the containers directly into the blender hopper. The portable support structure may include a frame for receiving and holding the one or more portable bulk material containers in an elevated position proximate the blender hopper, as well as one or more gravity feed outlets for routing the bulk material from the containers directly into the blender hopper. In some embodiments, the portable support structure may be transported to the well site on a trailer, unloaded from the trailer, and positioned proximate the blender unit. In other embodiments, the portable support structure may be a mobile support structure that is integrated into a trailer unit.

Mobile support structure for bulk material containers

In accordance with presently disclosed embodiments, systems and methods for managing dry bulk material efficiently at a well site or other location are provided. Present embodiments are directed to a rotary clamshell gate actuation system and method, where the gate is separate from the one or more actuators used to open/close the gate. The disclosed system may include a portable bulk material container with a clamshell gate for easily dispensing material from the container. The system also includes a support structure equipped with one or more rotary actuators used to actuate the clamshell gate of the container between a closed and open position when the container is positioned on the support structure. The disclosed clamshell gate actuation system is easy to operate, low cost to manufacture, and reliable even when the portable container is not precisely aligned on the support structure.

A device and a method are provided for the hydraulic fracturing of multiple zones in a well bore. A stinger carries a plurality of packers into a well bore. Each packer is separably connected to each adjacent packer. As each packer is sequentially secured in the well bore, the stinger is withdrawn from the secured packer and the process is repeated as the remaining packers are sequentially secured and separated.

A low pressure, high temperature composite bridge plug. The bridge plug comprises a mandrel with a plurality of slips disposed therearound. A wedge is initially attached to said mandrel and in planar contact with the slips for forcing the slips radially outwardly into gripping engagement with a wellbore. An elastomeric sealing element is disposed on the mandrel and compressed between the wedge and a shoulder on the mandrel to expand the packing element radially outward into sealing engagement with the wellbore. A plurality of ratchets retained in a ratchet body grippingly engage the mandrel to prevent the plug from unsetting. The mandrel, slips, wedge and ratchet body are preferably made of non-metallic, composite materials for easy drilling.

A joint coupling is disclosed for connecting sections of conduit. The present joint coupling includes a male connector portion having an inner side and an outer side, having a barb on one or both of the sides. A gasket is received on the male connector portion, and has one or more fins on the side opposite the barb. A female connector portion receives and engages the male connector portion and includes a first side having a lock down lip for engaging the barb and a second side for contacting the gasket fins. The fins bias the connector portions in an interference to create a transverse locking force that securely retains the connector portions. The connector portions can be formed directly on the sections of conduit, or can be formed on a discrete conduit cap or an intermediate coupler, for joining sections of conduit.

Pipe joint coupling

An extrusion assembly includes a stationary housing section, and an outer die and mandrel for defining an annular passageway centered about an axis. The outer die and mandrel are held stationary against rotational motion about the axis. A rotor is rotationally supported on a shaft projecting into the annular passageway along the axis within the housing, for rotational motion about the axis. The rotor includes a melt channel for rotationally conveying an extrusion to the annular passageway, so as to form a helically-wound conduit that advances linearly through the annular passageway. A gear train is operative between the stationary housing, the rotor and the shaft, to hold the shaft stationary relative to the stationary housing upon rotation of the rotor.

Apparatus for conduit extrusion

A force-transmitting joint formed between two pipe sections is provided that is particularly suited for an extruded, plastic pipe having a variable wall thickness. The joint has a smooth outer surface and a constant gap in which a sealing member is retained. The pipe section has an outer wall including an outer surface and an inner surface with a variable wall thickness defined therebetween. A first end of the pipe section includes a first joint member comprising a first support surface having a constant width. The first joint member further comprises an outwardly extending sealing leg having a variable width. A second end of the pipe includes a second joint member comprising a second support surface having a constant width which is less than the width of the first support surface. The second joint member further comprises a recess having a variable thickness. An annular sealing member is assembled onto the sealing leg. When the first joint member of one pipe section is joined to the second joint member of another pipe section, the first support wall and second support wall align in a force-transmitting relationship, the sealing leg is at least partially received in the recess and a constant-width gap is formed between a wall of the recess and the sealing leg. The sealing member is retained in the constant-width gap.

Joint for variable wall thickness conduit

A pipe joint and coupling construction particularly suited for joining large diameter plastic pipe as used in sewer relining. The construction comprises first and second sections of cylindrical pipe having axially aligned opposed end walls with a continuous groove formed in each end wall. The groove in each end wall is axially aligned with the groove in the opposed end wall and cooperates therewith to form a gasket receiving chamber. The coupling member is adapted to be mounted in the gasket receiving chamber for sealingly joining the pipe sections. It comprises a rigid annular core ring for mounting in the chamber to extend axially into each of the axially aligned grooves. A resilient compressible elastomeric covering is positioned over the core ring and carried circumferentially continuous radially extending protrusions which are sized to be sealingly compressed between the core ring and the side walls of the grooves.
