摘要： A fitting is disclosed that includes a body; a first flow passage extending through the body; and a second flow passage formed in the body to intersect the first flow passage. The first and second flow passages define first and second longitudinal center axes, respectively. In an exemplary embodiment, the fitting forms a portion of a manifold assembly of a frac system. In one aspect, the fitting is formed by a manufacturing process such that the body has a parting plane that is offset from, and parallel to, the first longitudinal center axis. The fitting may have a first varying wall thickness defined between the first flow passage and the external surface; and a second varying wall thickness defined between the second flow passage and the external surface. In another aspect, a curved surface is formed in the body at the intersection between the first and second flow passages.

摘要： To provide a spacer nut manufacturing method which uses no NC lathe, which allows machining using existing press working equipment, which involves a low parts supply cost, and which helps to achieve a high production efficiency at a low production cost.A method of manufacturing a spacer nut arranged between a casing and a board arranged inside the casing and serving to fix the board in position while keeping the board spaced apart from the casing by a predetermined distance dimension, the method comprising: a first step of forming a protrusion of a predetermined length on a metal plate material of a predetermined thickness dimension by press working; a second step of forging the protrusion into a shaft portion in the form of a bottomed cylinder and forming a flange portion at a peripheral edge of a proximal end portion of the shaft portion by press working; a third step of forming an opening at a distal end portion of the shaft portion by press working; a fourth step of performing pressing radially inwards on the proximal end portion of the shaft portion to form a groove portion extending circumferentially around the shaft portion; a fifth step of stamping the flange portion from the metal plate material while forming a serration portion along an outer periphery of the flange portion by press working; and a sixth step of forming a thread groove portion in an inner peripheral surface portion of the shaft portion.

摘要： An integral manifold for a heat exchanger is formed from a hollow shape having a plurality of individual risers, initially having substantially solid cross-sections and subsequently reshaped by means of a reverse impact extrusion process into hollow risers. The walls of the hollow shape under the hollow risers are perforated, thus forming apertures constituting inlets connecting the cavity of the hollow shape with the individual hollow risers.

摘要： A cup member has a cylindrical portion, a bottom portion, and a short shaft portion having a solid shaft shape and including a joining end surface at an end portion thereof. A shaft member has a solid shaft shape and includes a joining end surface at one end thereof. The joining end surfaces of the cup and shaft members are brought into abutment against each other and welded from a radially outer side to form a welded portion. At this time, center segregation is prevented from interfering with the welded portion. The cup member is formed by forging including upsetting a billet having a columnar shape successively in a plurality of stages, extruding the cylindrical portion and the short shaft portion, and ironing the cylindrical portion. In the course of the upsetting, a region of the billet corresponding to a bottom side of the cup member is narrowed.
