Turbine Sealant For Casings Parting Planes - Birkosit

















Product Data Sheet

BIRKOSIT - Dichtungskitt ®

for extreme conditions of temperature and pressure

Description:

BIRKOSIT is a single-component, paste luting agent / sealing compound for industrial use wherever conditions of temperature and pressure at smooth, plane sealing surfaces (butt joints) make extreme demands on the quality of the sealing compound.

Product data sheet
This applies, in particular, to the sealing
of metallic joints:
steam and gas turbines, compressors,
pumps, housings, flange joints etc.

Technical data:

Temperature resistance:
hot steam and air, hot and cold water, light fuel oils and lubricants, crude oil and natural gas at
up to 900 °C.

Pressure resistance:
The excellent adhesion on sealing surfaces and butt joints guarantees a perfect seal
up to 250 bar. The pressure resistance for flanges without sealing rings is up to 450 bar and even up to 550 bar for screw joints.

Plastic deformation:
is unlimited in its plastic workability so that, even under the most demanding conditions, the sealing film does not break. cf. temperature and pressure resistance.

Application areas:
Steam and gas turbines, power plants, gasworks and waterworks, oil refineries, smelting works, shipyards, paint and rubber manufacturing, chemical industry.

Working recommendations:
To be spread on the dry surfaces using a putty knife or rubber spatula. As the product doesn’t cure but slightly changes its consistence staying flexible and elastic, application on butt joints without time pressure is possible. And the product can be subjected immediately to working loads!
A small amount of linseed oil varnish may be added to improve the spreading properties.

Storage:
Unlimited storage life when correctly stored. Its properties are stable and it is flexible in use. The tin should be properly closed when only a part of the contents is used.

Packaging:
BIRKOSIT is packed and supplied in special 1-kg tins. Its colour is reddish-brown. For further properties of the product, see the materials safety data sheet 91/155/EEC, changed 93/112/EC and the storage life certificate. State of October 2009.
