FIELD: process engineering.
SUBSTANCE: invention relates to a of fiber glass higher-strength pipes to be used in aircraft engineering, shih building, chemical and petrochemical industries. Film epoxy resin-based glue BK-36 is wound on the mandrel while fiber glass layers are formed bi combined processes of fiber glass impregnation with film glue and forming impregnated fiber glass of alternating layers of glass fabric and film glue at glue volume content oif said fabric making 45-50%. Note here that said process is performed at 0.085-0.095 MPa for 30-40 minutes at 65-70°C and, further, for 100-120 minutes at 170°C.
EFFECT: higher tube tightness, simplified process.
