The present invention provides a transfer line exchanger which is optimized for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs. The transfer line exchanger is designed by computer modeling a transfer line exchanger in which the cross section of flow path is substantially circular and modeling the operation of the transfer line under industrial conditions to validate the model design and its operation. Then iteratively the model design is deformed and the operation of the deformed part is modeled and compared to values obtained with other deformed models until the value of the objective function is optimized (e.g. at an extreme) or the change in the objective function is approaching zero.

An unload elbow with spherical wear pocket is disclosed which comprises a body having an inlet end, an outlet end, and a spherical wear pocket formed near the outlet end. The spherical wear pocket is capable of trapping material that is being unloaded through the unload elbow to trap a portion of material being unloaded so that any other material being unloaded will contact the trapped material and not impact the wear pocket to prematurely wear out the unload elbow.

Provided herein are components for a fluid network modified for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs.

Provided herein are components for a fluid network, specifically a U bend structure connected to at least two pipes which is modified for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs. The U bend structure is so designed to have a specific ARQ between 1.0 to 1.02 for 5% of the flow passage from the inlet and from the outlet, and an ARQ from 1.02 to 1.15 over the remaining 90% of the flow passage through an Rb/D ratio being greater than 1 and less than 4.

Provided herein are components for a fluid network modified for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs.

A two-branch or multi-branch double-layer wear-and-impact-resistant tube and manufacturing method thereof. The wear-and-impact-resistant tube comprises an outer protective tube and an inner wear-resistant assembled tube nested in the outer protective tube. The inner wear-resistant assembled tube comprises two or more tube walls, the two or more tube walls are jointed to form a tube having an annular cross section. The wear-and-impact-resistant tube can be a straight tube or a bent tube. If the wear-and-impact-resistant tube is a straight tube, upper and lower portions of the inner wear-resistant assembled tube employ different structures, and if the wear-and-impact-resistant tube is a bent tube, a large curved portion and a small curved portion of the bent tube employ different structures. The inner assembled tube of the wear-and-impact-resistant tube is divided into at least two portions, and the at least two portions thereof employ different structures. The tube structure extends a service life thereof, improves wear resistance and impact resistance thereof, and reduces a total weight of the tube.

A ceramic-backed elbow featuring an extended chamber which alters the flow of fluent through the elbow section. This chamber is lined with a ceramic material and ceramic tiles. The remainder of the elbow is similarly coated with a ceramic mixture. The elbow could be placed into a coating pan upon the tiles being adhered to the elbow, and the entire elbow may be coated with an abrasive-resistant coating. A thin metal skin may then be applied over the entire surface of the coating.

Some embodiments of the present invention provide components for a serpentine fluid reactor which is optimized for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs. The components are designed by computer modeling the components individually and collectively in which the cross section of flow path is substantially circular under industrial conditions to validate the model design and its operation. Then iteratively the component designs are deformed and the operation of the deformed part(s) is modeled and compared to values obtained with other deformed models until the value of the objective function is optimized (e.g. at an extreme) or the change in the objective function is approaching zero.

An intake device for a pump includes an inlet section extending in a first direction for guiding a fluid, an outlet section for delivering the fluid to an inlet of the pump, the outlet section extending in a second direction perpendicular to the first direction, and a diverting section for diverting the fluid from the first to the second direction, the diverting section connecting the inlet and outlet sections, and having a bottom wall opposing the an outlet opening and a back wall opposing an inlet opening, the inlet section tapering towards the diverting section to decrease a cross sectional area of the inlet section, the diverting section includes a splitter member arranged on the bottom wall that tapers in the second direction towards the outlet opening, and the outlet section includes an essentially bell shaped reducing part for decreasing a cross sectional area of the outlet section.

The polymeric pipes reinforced with a metal casing are used for transporting oil and gas, acids, alkali products, drinking water and industrial water, and also in the transportation of aggressive and neutral pulps. A metal-containing polymeric reinforced pipe includes a welded metal casing and a polymeric matrix having an amorphous-phase-based molecular structure. The metal-containing polymeric reinforced pipe is produced by extrusion moulding with simultaneous feeding of a polymer melt and the reinforcing metal casing into the mould cavity, followed by intensive cooling of the internal and external surfaces of the pipe being moulded. The invention increases the quality and endurance limit in the radial direction of the metal-containing polymeric reinforced pipe, productivity of the process for manufacturing the pipe, and also the strength and technological effectiveness of a pipeline constructed from the pipes produced.
