Alleima Coupling L - spare parts Skip to content

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.
