摘要： A pipe branch structure includes a main pipe, and plural branch couplings disposed one-to-one at plural branch positions set between both axial direction ends of the main pipe. A cross hole is formed at each of the branch positions of the main pipe. Each branch coupling includes a tubular section attached to an outer periphery of the main pipe, a branch section formed with a passage in communication with an inside of the tubular section and configured to connect to a branch pipe, and a seal member configured to seal between the main pipe and the tubular section. The tubular section is attached to the outer periphery of the main pipe in a state in which the cross hole and the passage in the branch section are in communication with each other.

摘要： Disclosed is a fluid diverting device which comprises a saddle unit, a water dividing unit and a leakproof tube unit. The saddle unit includes a saddle body, a water inlet through hole and a main pipe accommodating portion. The water dividing unit includes a water dividing main portion, an inlet tube portion and an outlet tube portion. The inlet tube portion is inserted into the water inlet through hole. A screw thread is provided on an external tube wall of the inlet tube portion or on an internal tube wall of the inlet tube portion. The leakproof tube unit includes a sleeve portion, a connecting portion and a leakproof pad. The connecting portion is provided on one end of the sleeve portion and the leakproof pad is in tight contact with the connecting portion. A corresponding screw thread is provided on an external tube wall of the sleeve portion or on an internal tube wall of the sleeve portion. The sleeve portion is screwed with the inlet tube portion in a manner that the external tube wall of the sleeve portion is screwed with the internal tube wall of the inlet tube portion or the internal tube wall of the sleeve portion is screwed with the external tube wall of the inlet tube portion.

摘要： A screw hole of an upstream side joining block is formed only on an upstream side of a flow path port thereof in a longitudinal direction, a screw hole of a downstream side joining block is formed only on a downstream side of a flow path port thereof in the longitudinal direction and, between a guide part and an engaging part, an alignment mechanism aligns the positions of the upstream side and the downstream side joining blocks in a horizontal direction orthogonal to the longitudinal direction of the guide part to a center position of the guide part by using a portion of a reaction force that resists a bending force produced by the tightening force of a tightening bolt on a body and the upstream side and the downstream side joining blocks connected to each other.

摘要： To produce pipe connections to conduits (10), such as drinking water main lines which have been remediated using a liner (12), a pipe clamp (20) is attached after a bore (21) has been made, and is secured with a clamping strap (22), for example. A pipe connection adapter (14) with a flange collar (15) and a seal (34) arranged thereon is introduced from the inside of the pipe (10). The anti-rotation device (29) between the pipe clamp (20) and the pipe connection adapter (14) ensures that the latter assumes a precisely defined position, such that its flange collar (15), with a shape corresponding to the intersection curve of the conduit/bore, provides a seal on the liner (12) exactly on the edge (21) of the bore.
It is also proposed to insert the connector from the outside of the conduit (10). For this purpose, the end region (41) of the pipe connection adapter (14) towards the conduit is flexible and can either be compressed to the bore diameter via glide surfaces (48) or can be produced or prepared with a diameter-reduced end region (41) and then expanded into the sealing position by means of an inner sleeve. In each case, the end region (41) is surrounded by an elastomeric, flexible sheathing (38) which, preferably in a 2-component injection molding process, was connected by a material bond to the main body (40) of the pipe connection adapter (14).-

摘要： Missiles for frac manifolds manifold the discharge from a plurality of pumps. The missile comprises a missile body and inlet assemblies. The missile body has a straight primary bore and a plurality of feed bores. The primary bore extends axially through the missile body. The feed bores extend radially through the missile body and define a socket. An inlet assembly is associated with each feed bore. The inlet assembly comprises a nipple and a collar. The nipple has a bore extending axially between a spigot and a union end. The nipple is connected to the collar. The spigot is received in the socket of the feed bore. The union end is adapted for connection to a flowline component. The collar comprises mating parts releasably coupled together around the missile body. The nipple is thereby releasably coupled to the missile body by coupling the collar to the missile body.

摘要： A hydraulic component includes a component housing and a connection block. The component housing has an outer surface and an axial bore. At least one connecting channel extends from the outer surface to the axial bore. The connection block has a housing side with at least one connection bore, where the connection bore is in fluidic connection with the at least one connection channel. The outer surface of the component housing has a non-planar shape at least in the area of the at least one connecting channel, where at least one connecting bushing with a through hole is received in the at least one connecting channel and extends into the at least one connecting bore.

摘要： A pipe saddle includes a saddle body having an interior surface with a generally U-shaped cross-sectional shape defining an interior configured to receive a pipe therein. The saddle body includes a bottom wall portion. A support clip is included on the bottom wall portion of the saddle body. The support clip includes a side wall extending downward. A resiliently deflectable lower arm extends outward from a lower end of the side wall and generally opposing the bottom wall portion. The resiliently deflectable lower arm includes a catch at a free end thereof. The resiliently deflectable lower arm is configured to snap onto a support structure to attach the pipe saddle to the support structure.
