F-4D fluoropolymer tubes

(TU 6-05-1937-82)

Applications:

for transportation of any aggressive media (except for melted alkali metals) at medium pressures up to 0,4 MPa;
for lining of reactors and rectifying stills of column type, shut-off accessory, pumps, containers for storage of reactive media;
for manufacturing of sealing parts, contacting with aggressive media;
for manufacturing of flow transmitters and inductive counters;
for manufacturing of transmitters of flow meters and inductive counters;
for manufacturing of hanging contact network insulators of electrical railway transport.

Operating temperatures: from -60°Ñ up to +230°Ñ (for a liner).
