The drums (14) are rotated about two axes, the first axis being the principal axis of the drums (A) and the second axis (B) being nearly parallel with the direction in which the fibres are unwound, where the direction of rotation of the drums (14) about the second axis (B) is the same as the direction in which the hose under construction (3) is rotated. The apparatus for carrying out the method comprises a laying head (12) and a drum support platform (15), where the hose under construction (3) undergoes both rotation and advancing motion relative to the laying head (12), and where the reinforcing fibres (10) are unwound from drums (14) through a circular fibre guide (1 ) The further object of the invention is a method for building hoses reinforced with spirally laid fibres, wherein the reinforcing fibres (10) are laid on the hose surface through a rotating self-adjusting circular fibre guide (2) arranged substantially coaxially with the hose. The invention also relates to an apparatus for carrying out the above method.

Early life erosion tracking layer for high pressure fracking hoses

A rubber hose includes a distinctly colored inner wear indicator integrated into its liner, wherein a distance b of the inner wear indicator from the inner surface of the liner is less than 40% of the liner's thickness v , and height h of the wear indicator, measured perpendicularly to a longitudinal axis of the hose, falls between 1% to 90% of liner thickness v , or even from 10% to 40% of the liner thickness v . The inner wear indicator may have concentric sectional surface area of the inner wear indicator may even gradually decrease in the radial direction as a function of distance from the longitudinal axis. The rubber hose may be connected at one end to a plunger pump and connected at a second to a common manifold, in an oilfield pump system, or used in any hose application in an oilfield fluid pump system.
