FIELD: process engineering.
SUBSTANCE: invention relates to production of pipes from composites. Sid pipes may be used in construction of main lines. Pipes are made of coiled composite by controlled spiral winding effected by varying the angle, diameter and speed of winding. Spiral winding is effected with overlap of coils and fixation of their position by glue applied on composite surface. Coiled composite can be produced by impregnation of thermosetting binder with carbon, basalt and combined fabric.
EFFECT: simplified process, expanded process performances.
