Tube of glass fibre laminate

 Tube of glass fibre laminate

Tube ТСЭФ represents the layered material made by a method of continuous winding preliminary impregnated epoxy binder roving with subsequent it calcification.

 The tube glass fibre laminate is applied as insulating a material to a complete set of the high-voltage equipment (oil and air switches) for work in transformer oil and on air in conditions of normal relative humidity of an environment and frequency of a current of 50 Hz at temperature from 60°С up to 90°С and also for work in conditions of the raised humidity of an environment (95±2) % and temperature from-60°С up to 155°С.

 As a constructional material fiberglass plastic  pipes are applied in a role обсадных pipes to fastening oil and gas chinks and also in especially harmful manufactures as chemically proof pipes.

 Pipes fiberglass plastic can be applied with success as heat-insulated a material in electric dryers heaters and other equipment Connection of pipes among themselves can be made by means of the formed internal conic groove by means of pasted metal branch pipes and also can be made with external winding on the ends for cutting an external groove.
