Glass-lined steel sealing challenges
Glass-lined steel equipment is used by chemical
processors to deal with aggressive media under
demanding conditions. Yet the inherent demands
of such systems — high temperatures, alternating
system pressures, limited gasket loads and deviation
of sealing surfaces — can make it challenging to
maintain a tight, lasting seal.
While common Polytetrafluoroethylene (PTFE) material
offers good chemical resistance, it does not readily
conform to flange surface deviations, nor does it
resist creep particularly well under low gasket loads.
Incorporating compressible materials or fillers into
common envelope gaskets or filled PTFE gaskets, offers
only a partial solution.

Sealing challenges are even greater when gaskets for large flanges
(≥ DN 600/ASME 24”) are fabricated offsite. This often results in long lead
times, as well as shipping, handling and inventory challenges. These, along
with time-consuming and complex installation procedures, can complicate
turnarounds or delay start-ups.
Consequences of seal failure
Sealing with common envelope, filled PTFE or large prefabricated gaskets can
be challenging — especially if there is inconsistent quality across different
gasket brands or product lines. This may lead to premature gasket failure,
with consequences that range from problematic to catastrophic, including:
▪
Leakage/emissions
▪
Equipment corrosion/damage
▪
Production downtime
▪
Cost increase
▪
Risks to personnel safety

Gasket Tape Series 1000 addresses all the
challenges of reliably sealing large glass-lined steel
flanges.
Made of 100% expanded PTFE (ePTFE), this highly conformable tape is
chemically inert, and highly resistant to creep, cold flow and clamp-force
loss. Its proprietary barrier core maintains an extra tight seal even at
low loads.
Endorsed by De Dietrich, a leading manufacturer of glass-lined steel
equipment, Series 1000 is optimized for processes utilizing highly aggressive
media, as in chemical processing (e. g. specialty chemicals, agricultural
products, polymers), mining and minerals. Series 1000 is designed for use
in large (≥ DN 600/ASME 24”) or non-standard flanges typical of columns,
mixer vessels, reactors, storage and receiver tanks.
