Filter leakage, due to surface irregularities between a lid and a fixed flange, caused contamination in a plant. This increased the risk for chemical burn injuries and corrosion of nearby equipment. The fragility of PVC flanges limited the ability to solve the problem by simply increasing the bolting torque on the flanges (i.e., increasing gasket seating stress).
PACKING STYLE TEADIT® 2773 CASE HISTORY
Pumping of abrasive fluids is one of the fundamental stages of the production process of a Sugar and Alcohol Plant. The use of low mechanical resistance packings in pumps means a greater number of packing replacements, affecting the plant productivity.
TEALON™ TF1580 CASE HISTORY
This equipment often suffered internal leakage and clogging of its channels due to the fragmentation of the original gasket, affecting its thermal performance. A skived PTFE gasket presents a fragile behavior when compressed by the fins of the heat exchanger. Steam injection was a frequent practice to maintain the required level of steam necessary for equipment operation, resulting in atypical operational cost of $225,000.00 every 6 months.
TEADIT® 24B CASE HISTORY
A manufacturer of
blowers was having difficulty sealing a new nitrogen blower for a large
manufacturer of commercial and consumer products. Blowers can be very challenging
sealing applications, as they often have very complex sealing areas which require
a non-standard gasket as standard flat gaskets can be extraordinarily
difficult to install, if even possible, and require a lengthy installation
process
2238-OX Case History
A major oil and gas company had an accident at a gas separation facility in the Middle East in a system in oxygen service. This is a critical service which poses a large safety risk to the facility and requires very careful selection of materials and extreme cleanliness standards. After the incident the customer initiated the process of re-evaluating the materials, including sealing products, that they were utilizing in this extremely critical service. The customer began searching for the best technical solution for packing material to equip all their on/off valves in the plant with.

Case History Sealpack 47 & 2774
A large sugar mill was having issues with constant leakage out of their
sugar crystallizer mixer, which is operating at 30psi and 180°F, with a rotational speed
of 10RPM. Agitators on large mixers such as this can pose more challenges to
braided packing than would appear from the basic operating parameters. Large
agitators in general tend to have challenges with shaft alignment which can
pose a serious issue for braided packing as it creates uneven wear on the
packing and can lead to premature failure. Find out how Teadit provided two unique solutions for this type of application!
Teadit 24SH – Spiral Heat Exchanger Case History
A biochemical manufacturer reached out to a Teadit partner for support
regarding premature gasket failure on a spiral heat exchanger. Spiral heat
exchangers pose some unique challenges for sealing due to their very large
diameter as well as their unique sealing surface. Read more about the solution provided by Teadit that not only fixed the issue, but reduced maintenance cost, production loss and installation failure!
TEADIT® 2005 – Harsh Chemical Agitator CASE HISTORY
A major chemical processing customer was experiencing media leakage of
harsh chemicals from packing on some of their agitators. Large diameter
agitators such as this can pose many challenges for braided packing sets. This
type of equipment often suffers from shaft alignment issues as well as worn or
damaged shafts which can be difficult scenarios for braided packing to be
successful in. This specific application posed another challenge in the form of
the packing configuration being utilized in the equipment. Previously the
customer had been utilizing a packing configuration consisting of 10 rings of
PTFE packing. A configuration with a high amount of packing rings such as this
can lead to an insufficient amount of load being applied to each ring. In
packing sets the load / stress applied is greater at the rings closest to the
gland follower and will decrease for each ring further away from the top ring.
TEADIT 24SH - Electrolytic Nickel Plant
A recently acquired Nickel Plant was experiencing leaking flanges, however it was posing serious safety and environmental concerns! The customer turned to Teadit, knowing we strive to seal for both a safer and greener tomorrow. Find out the which of our products was the fix here, as well as how we were able to provide a six figure savings!
Teadit 2235 -- Steam Valves
Steam service requires a material that can withstand high
temperatures for an extended period without degradation, and valves require a
packing material that is robust and pressure resistant without damaging the
valve stem. A major petrochemical plant was having problems with high temperature, superheated steam leaking from valve stems throughout the facility. Leakage of such high temperature steam posed a significant safety risk for all those on site and the leakage was also negatively influencing the quality of the process. In addition, the steam leakage was causing extremely high maintenance costs due to down time. Steam valves can prove to be a challenging application to create an effective, long term seal.
Teadit 2002 – Paper Refiner
A
major paper manufacturer was not achieving their desired level of performance
from their previous packing material on their refiner. A common challenge in pulp and paper applications,
such as this, is that the media is often abrasive which can be difficult for
mechanical packings and requires a packing material with more mechanical
strength to resist wear from the media. Another common challenge in certain
rotating equipment applications is that a high amount of heat is generated due
to friction between the packing and the shaft. The thermoset packing material
is not ideal for handling abrasive types of medias and required a high amount
of flush water in order to dissipate the friction heat, as it does not have as
high of heat dissipation properties as other types of packings. Find out how Teadit found solutions and savings for their customer...
24SH - Seawater Pumps
An industrial facility was using sea water for their cooling system and
wanted to change from graphite gasketing material due to potential galvanic
corrosion.
