Circular, watertight, heat-sealed bellows

Watertight circular bellows

The thermo-welded watertight circular bellows are used when watertight protection is required over the parts to be protected (for example screws, stems, etc.) against contamination of coolant liquids. They have good resistance to chemicals and are heat compatible with the materials used.

The thermo-welded watertight circular bellows can be supplied in the most diverse shape structures after setting up equipment of modest value (if not already existing in our warehouse).

Data

Type A fixing schemes

Bellows with the type A fastening system have with collar and a flange

Bellows data:

Ø e. soff. = Circular bellows outer diameter
Ø i.c. = Internal collar diameter
Ø i. soff. = Bellows internal diameter
Ø i.f. = Internal flange diameter
Ø int. holes = Flange hole centre-to-centre diameter
Ø e. f = Flange outer diameter
P.A. = Open parcel
P.C. = Closed parcel
Corsa = P.A. – P.C.
AP = Open step
X = Bellows fold height

Type B fixing schemes

Bellows with type B fastening system have two collars

Bellows data:

Ø e. soff. = Circular bellows outer diameter
Ø i.c. = Internal collar diameter
Ø i. soff. = Bellows internal diameter
P.C. = Open parcel
Corsa = P.A. – P.C.
AP = Open step
X = Bellows fold height

Type C fixing schemes

Bellows with the type C fastening system have two flanges

Bellows data:

Ø e. soff. = Circular bellows outer diameter
Ø i. soff. = Bellows internal diameter
