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.

A system and method of use thereof to produce pipe connections to conduits which have been remediated using a liner. A pipe clamp is attached after a bore has been made and is secured with a clamping strap, for example. A pipe connection adapter with a flange collar and a seal arranged thereon is introduced from the inside of the pipe. An anti-rotation device between the pipe clamp and the pipe connection adapter ensures that the latter assumes a precisely defined position, such that a flange collar, with a shape corresponding to the intersection curve of the conduit/bore, provides a seal on the liner exactly on the edge of the bore. Connection can also be made from the outside of the conduit.

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.

A gas distribution assembly that includes a valve mounted on a distribution duct. According to one implementation the body of the valve is supported on the duct by support having a base and a plurality of arms extending from the base. The arms have surfaces that rests on projections of the valve body. A fixation device is furthered used to secure the support to the valve body. The support is configured to hold the valve body on the duct in the event the fixation device fails to secure the support to the valve body.

According to one embodiment a gas distribution assembly is provided that includes a gas distribution duct and at least one gas regulating valve mounted on the gas distribution duct. The valve is secured to the duct by use of a support supported on the duct and attachment means for attaching the valve to the support. According to one embodiment the attachment means comprises a screw threaded into a threaded sleeve and also into a threaded hole in the body of the valve. The support includes a through hole through which the sleeve passes and the sleeve includes a flange at one end that rests on the support in an area that surrounds the through hole. An end of the sleeve opposite the flange resides adjacent the threaded hole in the body of the valve.

The present invention relates to a sprinkler system, and more specifically, to a sprinkler system which can be assembled without welding. To this end, the sprinkler system according to the present invention comprises: a main pipe through which fluid is supplied from an externa source; a first branch pipe for branching the fluid supplied through the main pipe; a second branch pipe for branching the fluid supplied through the first branch pipe so that said fluid is supplied to a sprinkler; and a detachable first coupler for interconnecting the main pipe, the first branch pipe, and the second branch pipe.
