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.

An easily polymerizable substance handling device is provided that can prevent generation of irregularities and steps between a pipeline and a cover member due to the cover member being installed at an opening part of the pipeline. A cover part 3 is formed to have a curved surface 3a on a side closer to inside of a pipeline 1. The shape of the surface 3a on the pipeline 1 side is preferably a concave shape when viewed from inside of the pipeline 1. The shape of the surface 3a of the cover part 3 on the pipeline 1 side is more preferably the shape of a curved surface having a curvature radius equal or approximate to that of the internal circumference of the pipeline 1. With this configuration, a polymer material is unlikely to be generated at the cover part 3 and around a gap 1b at an opening part 1a, and the frequency of cleaning can be reduced as compared to conventional cases.

A steel pipe is for drilling, exploiting hydrocarbon wells, transporting petrol and gas, carbon capture or geothermal energy. The steel pipe includes at least one male or female insert and a metal body. The insert includes at least a first thread axis, at least one toric or frusto-conical sealing surface, a threaded portion and a non-threaded portion connected to the metal body. The metal body is made entirely by additive manufacturing and the insert includes an anchoring profile arranged so as to adhere the additive material of the metal body.

A fluid connection assembly that includes a plurality of tubes having a first open end and a second open end opposite the first open end and a plurality of connectors. Each of the connectors include at least two connector portions, in which each of the at least two connector portions extend from a center of the connector and have a first end connected to the center of the connector and a second end connected to the second open end of one of the plurality of tubes. The connector portions are continuously formed with the tube and the center of the connector and the connector portions are fluidly connected together.

The T-head coupler is intended to perform a cleaning-in-place of a blackwater tank inside a recreational vehicle, using a mixture of water and a cleaning agent. To accomplish this, the device includes a unique arrangement of ports and distribution channels, wherein the ports on the device are designed specifically to couple with ports commonly found in RVs and water sources. In addition, a container filled with a cleaning agent is attached to the bottom port on the device. When all attachments are made, a plurality of channels within the device direct incoming water to the container. The water mixes with the cleaning agent inside the container, forming a cleaning solution. The cleaning solution flows out of the device, using the pressure from the water source. The cleaning solution then flows from the RV port and into the blackwater tank, thereby cleaning the tank.

A quickconnect structure having a fitting connector, a connector, and U-shaped positioning snap pin. The fitting connector has a connector part, a fitting connector body part coupled to the connector part, and a fitting part coupled to the fitting connector. The connector part, the fitting connector body part, and the fitting part define a fitting hole extending therethrough, and the fitting part defines positioning groove, a longitudinal snap hole, and a side snap opening in communication with the longitudinal snap hole. The connector has a connection end, a connector body part coupled to the connection end, and a positioning bump. The connection end and the connector body part define a duct hole extending therethrough, the connection end defines a positioning snap groove, and the fitting connector is configured to accept the connection end in the fitting hole. When the connection end is fully inserted into the fitting connector, the positioning bump is located in the positioning groove, and the longitudinal snap hole is aligned with the positioning snap groove. The U-shaped positioning snap pin has a pin base, a pin body part coupled to the pin base, and a snap protrusion coupled to the pin body part. The U-shaped positioning snap pin is configured to be partially inserted and fully inserted into the longitudinal snap hole; when partially interested, the snap protrusion engages the side snap opening and the connector is able to be inserted into the fitting connector; and when fully inserted and when the connector is inserted into the fitting connector, the pin body part engages the positioning snap groove and the snap protrusion engages a longitudinal snap hole exit.

A flow substrate mounting structure comprising a fastener aperture and an alignment feature, wherein the alignment feature comprises at least one of an alignment pin removably coupled with the flow substrate mounting structure, an alignment slot, and an alignment step.
