FIELD: machine building.
SUBSTANCE: invention refers to the production of tubes of composite materials. Pressure tube made of the thermosetting composite of bamboo and sand has the internal finishing layer (1), the inner reinforcing layer (2), the sealing layer of bound sand (3), the outer reinforcing layer (4) and the outer protective layer (5). Pipe is made by means of winding the material from the inside outward in the radial direction. Inner reinforcing layer (2) is formed by means of winding the bamboo strips. Sealing layer of bound sand (3) is formed by means of applying the mixture of sand and the binder. Outer reinforcing layer (4) is formed by means of winding the bamboo strips. Layers are applied successively from the inside out, beginning with the inner finishing layer (1) and ending with the outer protective layer (5).
EFFECT: composite pressure pipe is the energy-saving and environmentally safe product, which uses raw materials to be recycled, and is characterized by a low price.
