Flanges (FCLF)
All flanges are stocked in ASTM 316L, with butt welding ends.
Blind flanges (FCLFB)
In ASTM 316L.
Clamps (FCLC)
For couplings up to and including DN 150/168.3 we stock these parts in EN 1.4301/1.4306. DN 200 and 250 are available in carbon steel only.
Bolts (FCLB) and nuts (FCLN)
For couplings up to and including DN 150/168.3 we stock these parts in ASTM 304 (A2-70). DN 200 and 250 are available in carbon steel only.
Locking ring (FCLLR)
For diameters up to DN 150/168.3 we stock the suitable locking rings in ASTM 304.
Gaskets
Besides resistance to temperature and chemicals there are two more functions - elasticity and plasticity - that decide the sealing capacity of a gasket. Sandvik Coupling L can be supplied with three different types of massive O-rings, all providing a complete tightness.
Nitril (FCLG-N)
Rubber gaskets for maximum temperature 100°C (210°F). The Nitril gasket is an inexpensive gasket with good elasticity.
Viton (FCLG-V)
Rubber gaskets for maximum temperature 150°C (302°F). Lead cured Viton grade. Sizes 26.9 - 205 are available from stock.
PTFE (FCLG-T)
PTFE gaskets for maximum temperature 260°C (500°F). Can be used in almost any medium. Note: PFTE gasket may have to be replaced when the pipeline is used after a temperature drop. The gasket will be tight again when the previous temperature is reached again. PTFE should be used only at constant temperature level, max. 260°C (500°F). Temperature variations might cause leakage due to the different heat expansion of PTFE and steel.
