Tubes (bushes) are produced by ram extrusion of heat-treated granular fluoroplast of «О», «Т», «PN» grades (TU 10007–80), fluoroplast-4А of F-4А–1, F-4А–2 or F-4А–3 grades (TU 6–05–1999–85).
Tubes (bushes) are intended to be used as pipelines and pipelines trimmers for transportation under corrosive mediums pressure, with the exception of alkali metals melts, trifluorochlorine and fluorine.
Working medium pressure depending on operation temperature is calculated by formulas given in TU 6–05–1876–79.
Tubes (bushes) are also intended for production of electrical insulating and anticorrosive purpose parts.
Tubes (bushes) operation temperature interval is from minus 200°С to plus 260°С.
Warranty period of storage is 20 years from the date of production.

NOTE:
Tubes (bushes) are supplied from 50 to 2000 mm height.
During tubes (bushes) specification preparation customer is to give only nominal sizes (outer diameter and wall thickness) and total weight without tolerance giving.
Production of other sizes tubes (bushes) is possible according to customer and manufacturer agreement.
