A plastic valve for preventing distortion is disclosed. The plastic valve comprises a connection member made up of plastic, a case member formed on an outer surface of the connection member, and a flange member made up of plastic and formed at an end part of the connection member. A pipe is connected by being inserted into a hole of a central part of the connection member and a distortion prevention member for minimizing a force corresponding to distortion applied in a direction opposed to a direction of the connection is formed in the flange member. The connection member is made up of fluoride resin and the case member is made up of engineering plastic.

A quick connector structure includes a fitting connector, a connector, and a U-shaped positioning snap pin. The fitting connector is a pipe connector, a three-way valve connector, or a washing machine valve connector. The fitting connector is combined with a pipe body. The U-shaped positioning snap pin ensures the stability of the connection between the fitting connector and the connector. The quick connector structure enables rapid positioning and assembly, reducing the assembly difficulty in a smaller or concealed space and achieving the effects of assembly stability and convenience.

A fluid coupler including a ferrule adapter having a body with a receiving bore for receiving a fluid conduit, a stop axially spaced away from the body and configured to engage an end of the fluid conduit, and a connector configured to adjust the axial distance between the body and the stop.

Methods, devices, and systems for a universal pipe sleeve junction for an aspirated smoke detection system are described herein. In some examples, one or more embodiments include a sleeve body having an outer surface and an inner surface, the inner surface defining an opening through the sleeve body, wherein the sleeve body further includes a first end surface and a second end surface opposite the first end surface, and a nozzle having an outer surface and an inner surface, the inner surface of the nozzle defining an opening through the nozzle and extending through to the inner surface of the sleeve body, where the nozzle opening is configured to couple with a pipe sleeve attachment mechanism.

A modular multiport pod missile includes a plurality of pipe sections securable together to form a conduit for transporting a fluid in a generally horizonal direction of travel, and at least one pod secured between two of the pipe sections forming the conduit. Each pod has a plurality of input ports extending radially outwardly at an angle from a perimeter of the pod. Each of the input ports is configured for connection to a high-pressure line for delivering a high-pressure fluid from a pump to the conduit. The input ports are angled such that, when connected to a high-pressure line, high-pressure fluid flowing through the input ports merges with the fluid in the conduit generally in the same direction of travel as the fluid in the conduit.

An X-pipe for an automotive engine exhaust system is made from a pair of 3-inch diameter metal pipes, each formed with a central bend and a pair of outboard bends. Each pipe is formed to have an oval-shaped central opening, and the two pipes are welded together along a central plane at the oval-shaped central openings. The resulting X-pipe may then be welded into an exhaust system and then installed on a vehicle with an internal combustion engine, and reduces rasp on startup, harmonizes exhaust flow between the cylinder banks on the engine, and improves tonal pleasantness of the exhaust note.

A pipe assembly is provided, the pipe assembly comprising a first pipe having a side opening on a side surface of the first pipe. A plate in the first pipe is arranged adjacent to the side opening and at an angle relative to a radial axis of the first pipe such that a first side of the plate may be lower than a second side. A vent hole may be proximal the side opening on the side surface of the first pipe.

A system for transferring fluid from a pump to a manifold, the manifold having a plurality of fluid inlets. A first pump truck includes a first pump having a first fluid outlet. A first flexible pipe couples the first fluid outlet to a first fluid inlet. The first flexible pipe is self-supporting and forms an arch extending over the first pump truck. The first pump truck may include a second pump having a second fluid outlet and a second flexible pipe may couple the second fluid outlet to a second fluid inlet. A second pump truck may include third and fourth pumps having third and fourth fluid outlets, respectively, that may be coupled to third and fourth fluid inlets by third and fourth self-supporting flexible pipes.
