WORKING CONDITIONS (PARAMETERS):
Pressure: do 2500 psi lub 160 bar
Temperatura: od -220°C do 550°C
CONSTRUCTION
Manufactured from SS316L steel (an inner ring and a spiral), galvanized carbon steel (centring ring) and expanded graphite or PTFE (an insert in the spiral). They are manufactured according to the following norms:
-
ASME B16.20
-
PN-EN 1514-2
-
PN-EN 12560-2
At the request of the client it is possible to manufacture seals of another, non-standard dimension and material for different working conditions.

ASME B 16.20 for fl anges according to ASME B 16.47 series A
-
ASME B 16.20 for fl anges according to ASME B 16.47 series B
TYPES OF CONSTRUCTION

GAMSPIR®
Manufactured from a spirally wound stainless steel tape and a fi ller. Standard thickness of a gasket is 4.5mm. A GAMSPIR gasket is applied in a tongue and groove fl ange joints (type C/D and E/F)

GAMSPIR® I
Made of a GAMSPIR gasket and connected with an inner ring. Such a solution prevents the gasket from highly aggressive or oxidizing media, as well as from excessive distortion caused by assembly clamp. GAMSPIR I is applied for fl ange joints type E/F.

GAMSPIR® O
Made of a GAMSPIR gasket and connected with an outer centring ring. Such a solution prevents the gasket from blowout in high pressures and from too strong compression of the gasket. Additionally it facilitates concentric assembly of the gasket.

GAMSPIR® IO
Made of a GAMSPIR gasket and connected with an inner and outer (centring) ring. Thanks to such a solution the gasket features very high resistance to compression and easy assembly. This version is recommended for fl at fl anges with coarse pads.
