A storage container having a base storage compartment configured to receive a divider by which the storage compartment is divided into two or more sub-compartments, wherein divider includes a tool configured to provide a secondary utility or function unrelated to dividing the storage compartment.

A petroleum pipeline safety system for preventing contamination of an environmentally sensitive area close to a pipeline is provided. The system includes a first portion of the pipeline including an upstream portion of the pipeline supplying a flow of fluid material and a flow restriction downstream of the first portion of the pipeline. The system further includes a second portion of the pipeline downstream of the flow restriction, receiving the flow of fluid material from the first portion and conveying the flow of fluid material through the environmentally sensitive area to a downstream portion of the pipeline. The flow restriction is configured to create a lower pipeline internal pressure within the second portion as compared to a pipeline internal pressure within the first portion. The system further includes a third portion of the pipeline downstream of the environmentally sensitive area and including the downstream portion of the pipeline.

A ventilation flow rate regulator for a pressurised tank of a vehicle. The regulator includes a body including a gas inlet and a gas outlet, and at least one restrictor mounted movably relative to the body. The restrictor is mounted to reduce a cross-section of at least one path of a gas flow proceeding from the inlet to the outlet, when a flow rate at the inlet is greater than a predetermined threshold. The regulator is arranged so that the cross-section remains non-zero irrespective of a flow rate.

A regulator may include an inlet from which a high-pressure fluid is introduced, a valve seat provided at the inlet, and a pressure regulating valve body. The fluid may pass an opening between the valve seat and the valve body formed with a communication passage to a pressure regulating chamber. A load generated by pressure of pressure-regulated fluid acting on a piston unit joined to the valve body may be balanced with a load by a pressure regulating spring in an atmosphere chamber provided coaxially in parallel with the pressure regulating chamber on an opposite side of the piston unit. Fluid pressure of the pressure regulating chamber may be controlled by changing an opening area between a valve-seated seat and the valve body. The valve seat holding the valve-seated seat may be installed on an elastic member via a buffer having a sliding performance.

Described is a flow control device comprising a body locatable with a tubular and a flow regulator, housed within the body. The flow regulator defines a flow path through the body to accommodate flow between internal and external locations of a tubular in use. The flow regulator comprises a valve arrangement forming part of the flow path, and a biasing mechanism configured to urge the valve arrangement towards an open configuration from a restricted configuration in which fluid flow though the flow path is restricted. The biasing mechanism and the flow path through the flow control device are configured such that a differential pressure acting across the flow regulator, in excess of a particular threshold, moves the valve arrangement from the open configuration towards the restricted configuration in order to limit flow through the flow control device.

A valve includes a valve body forming a channel defining a fluid flow path extending from an inlet port to an outlet port of the valve body via a gallery disposed therebetween, an opening disposed in communication with the gallery, a valve assembly at least partially disposed through the opening and in the gallery, and a set pin having a central longitudinal axis. A valve disc of the valve assembly moves between a first position spaced from a valve seat of the valve body and a second position in contact with the valve seat. The set pin is coupled to and at least partly supported by the valve assembly to maintain the valve assembly in the first position. The fluid flow path allows a fluid to flow through the valve body in a first direction and a second direction opposite the first direction. The set pin is adapted to disengage a portion of the valve assembly when contacted by a fluid traversing the fluid flow path in the second direction, allowing the valve disc to move to the second position.
