A sealing assembly creating a sealed flow path between fluid ducts. The seal assembly comprises a housing and a tubular element within the housing providing a fluid conduit between the fluid ducts. Two sealing elements each have an internal sealing face sealably engaged with the tube and an external face for sealing, in use, with a respective fluid duct. At least one of the sealing elements is slidable with respect to the tubes. A support is slidably retained by the housing, surrounds one end of the tube and supports one of the slidable sealing elements on the side of the sealing element opposite to its external face. A resilient element within the housing biases the support so as to urge the two sealing elements apart.

A decompression heat-insulating pipe structure that can exhibit the desired heat-insulating performance and is easy to assemble. In the structure, a space between ends of inner and outer tubes is decompressed. The outer tube includes a first flange, which extends radially inward from an axially one end thereof, and a second flange, which extends radially outward from the axially other end thereof. The inner tube includes a third flange, which extends radially inward from an axially one end thereof and is opposed to the first flange at an axially inward position of the first flange, and a fourth flange, which extends radially outward from the axially other end thereof and being opposed to the second flange at an axially outward position of the second flange. First and second elastic seal members are disposed between the first and third flanges and between the second and fourth flanges, respectively.

A pipe support system includes a base having a collar, and an extension assembly that includes a threaded member having a first end and a second end. The first end has a leg configured to be received by the collar such that the extension assembly is supported by the base, and the second end has a tube with exterior threads. The extension assembly also includes a nut member having corresponding interior threads. The pipe support system also includes a support having an arm configured to be received within the tube and a head extending from one end of the arm. The support rests on the nut member such that upon rotation of the nut member, the head either raises or lowers with respect to the base.

A hose clamp and various methods are disclosed. The hose clamp includes a spring liner.

A pipe support has a pair of arms. The first end of one arm has a tongue and the first end of the other arm has an elongate groove configured to slidably receive the tongue. Base plates are pivotably connected to the second ends of both arms.

An expansion compensator are at least two axially extending elongate members, which combined, circumferentially extend around the expansion compensator while each elongate member individually circumferentially extends only part way around the expansion compensator.
