A tubular liner for a pipe is collapsed on itself to define a pair of lobes. The lobes are folded into a central region so that bending modulus and radius are reduced. The liner can be stored in a tighter coil and can be introduced into an underground pipe to be lined at a more acute angle.
Reinforcement of buried or inaccessible existing pipes is achieved by applying a reinforcement layer which includes a fabric portion. A pipe system structure is achieved which permits an internal or external surface of an existing pipe wall to be reinforced without removing a section of the pipe and without requiring the pipe to be out of service of a long period of time. The reinforcement layer overlays a portion of the internal or the external surface of the pipe. An adhesive material is then ...
There is provided an insulation kit comprising an inner waterproof layer for contacting a pipe to be insulated. On the outside of the inner waterproof layer there is insulation. Then, on the outside of the insulation there is a protective layer to guard the insulation from being damaged by rock, hammer blows, knife marks and the like. The insulation kit can be taken to the field and applied to the exterior of the pipe in a relatively short period of time. The electrical fusion wire can be activa...
The preferred embodiment of the invention is a fluid pressure alleviating pneumatic or hydraulic system component. The invention is comprised of a diaphragm, carrier and a release mechanism. The diaphragm is attached to the carrier. The release mechanism bears against the diaphragm and positions it such that fluid pressure on the surface of the diaphragm produces only or primarily shear force at the connection between the carrier and the diaphragm. The connection and parts have sufficient streng...
A pressure restrictor for use with a pressure sensing element comprising a cylindrical member of a given diameter and length having a plurality of apertures directed from a first end to a second end is disclosed. A pressure restrictor housing holds and positions the cylindrical member in close proximity to the pressure sensing element at the second end by clamping the pressure restrictor between the housing and element. The apertures provided in the pressure restrictor are the sole path for appl...
Described is an insulation module (1) for a vessel (2) used in a chemical plant. The module may take the form of a panel having an outer surface layer (3) and an insulation layer (5) secured to the outer surface layer (3). Mounting means (10) extends from the panel (1) and enables mounting of the insulation module (1) on an outer wall (2) of the vessel. An air gap (15) is provided between the insulation layer (3) and the outer vessel wall (2) when the insulation module is mounted (1) on the vess...
A rubber composition for an automotive non-water liquid delivery hose, which has good adhesion, comprises (A) chloroprene rubber, and (B) ethylene-propylene-diene terpoylymer containing 3% to 11% by weight of ethylidene norbornene and having a Mooney viscosity (ML.sub.1+4 at 100.degree. C.) in the range of 20 to 150, wherein the mixture ratio by weight of the component (A) and the component (B) is set in the range of (A)/(B)=97/3 to 75/25.
A pipe having an axially extending bore is defined by a pipe wall including a corrugated outer wall having axially adjacent annular outwardly-extending crests separated by valleys. The pipe wall also includes a non-linear outer layer having adjacent concave portions and convex portions. The concave portions are aligned with the corrugation crests of the outer wall so that the convex portion of the outer layer extends outwardly between at least two corrugation crests to provide improved resistanc...
The invention relates to a mass tube (1) for an air measuring sensor (3) comprising a metal grid (4) acting as a flow rectifier arranged perpendicular to the air flow (2). At least two fixing elements (5) are arranged on the measuring tube (1), said elements extending inwards in a radial manner, whereon the metal grid (4) is fixed by pre-tensioning.
A pressure vessel assembly is provided for a pressurized fluid system. The pressure vessel assembly comprises an outer casing defining an interior cavity within the outer casing, at least one fluid-pressure accumulator disposed within the interior cavity in the outer casing, and at least one isolation device disposed between the at least one fluid-pressure accumulator and the outer casing.
