FIELD: construction.
SUBSTANCE: fiber glass section of pipeline comprises cylindrical housing with the end sections and thickening at the end for threaded funnel or nipples. The wall of the housing is defined by the fiber glass impregnated with the binder. The fibers are wound in several layers over the radial-axial spirals in the opposite directions. The thickening of the end section and the intermediate cylindrical section are defined by the fiber groups which are arranged in the intermediate section with a given step and are overlapped in a staggered order. The fiber groups are interweave at an angle of 45-65° to the longitudinal axis of the section.
EFFECT: enhanced reliability.
