BIRKOSIT - sealing compound ®
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.
This applies, in particular, to the
sealing of: steam and gas turbines, compressors,
pumps, housings, flange joints etc.
Application:
Principal area of application in steam turbines and gas turbines (click
for more information)
Use of the product in the application area, metal-to-metal joints
[Compressors] (click for more information)
Technical data:
Temperature resistance:
will withstand hot steam and
air, hot and cold water, light fuel oils and lubricants, crude oil and
natural gas at up to 650 °C.
Pressure resistance:
The excellent adhesion on
sealing surfaces and butt joints guarantees a perfect seal up to 135
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:
manufacture of steam and gas
turbines, power station, gasworks and waterworks operations, oil
refineries, smelting works, shipyards, paint and rubber manufacture,
chemical industry.
Working recommendations:
is spread on the dry surfaces
using a putty knife or rubber spatula. The product can be subjected
immediately to working loads. The hardening time of several hours allows
butt joints to be properly bedded. A small amount of linseed oil varnish
may be added to improve the spreading properties.
Storage:
unlimited storage life when
BIRKOSIT is 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.
