Embodiment Construction

[0223] figure 1 The stresses to which hose H is typically subjected during use are shown. The hoop stress is indicated by the arrow HS, which is the stress acting tangentially on the circumference of the hose H. As shown in FIG. Axial stress is indicated by arrow AS, which is the stress acting axially along the length of the hose H. As shown in FIG. The flexural stress is denoted FS, which is the stress acting transversely to the longitudinal axis of the hose H when the hose H is bent. Torsional stress is denoted by TS, which is the twisting stress acting about the longitudinal axis of the hose. The crushing stress, denoted CS, is generated by a load applied radially to the outside of the hose H.

[0224] The hoop stress HS is generated by the fluid pressure in the hose H. The axial stress AS is created by the fluid pressure in the hose and the combination of the fluid weight in the hose H and the weight of the hose H itself. The flexural stress FS is caused by the need t...

Abstract

A hose comprising: a. a first clamping member; b. a first tubular body of flexible material overlying said first clamping member, said first tubular body comprising a a first reinforcement layer, a sealing layer overlying the first reinforcement layer, a second reinforcement layer overlying the sealing layer; c. a second clamping member overlying the second reinforcement layer; d . a second tube of flexible material disposed around said second clamping member; and e. a third clamping member overlying said second tube. The invention also provides a method of manufacturing the hose.

Description

[0001] The present invention is a divisional application of the Chinese invention patent "reinforced hose" with the filing date of August 10, 2007 and the application number of 200780037802.8 (PCT / GB2007 / 003059). technical field [0002] The invention relates to a hose, especially a hose that can be used under low temperature conditions. The invention is particularly concerned with hoses having improved compressive strength. [0003] Typical applications for hoses include pumping fluid under pressure from fluid reservoirs. Examples include supplying domestic heating oil or liquefied petroleum gas (LPG) to boilers; transporting field-produced liquids and / or gases from fixed or floating production platforms to ship cargo holds, or from ship cargo holds to shore-based storage units; especially in During refueling in a Formula 1 race, delivering fuel to sports cars; and delivering corrosive fluids, such as sulfuric acid. Background technique [0004] The use of hoses to transp...
