Venting solution
W.L. Gore & Associates Inc., Elkton, Md. |
A new protective vent with metal housing
performs successfully even in extreme conditions, such as widely fluctuating
temperatures, extreme moisture, and large amounts of environmental contaminants,
according to the company. Like other Gore vents, this product provides good
protection and pressure equalization for electrical enclosures, outdoor
electronics, domestic appliances, and a range of other products containing
electronic components. Gore protective vents allow air to pass freely through
housings, so they virtually eliminate the stress caused by sudden changes
in temperature and pressure that can compromise gaskets or housing seals.
These vents also provide the advantage of easy access to sensitive electronics
for maintenance without allowing contaminants, such as water, chemicals,
oil, or dust, to enter the housing. Gore vents typically are used in pressure
or gas sensors, in electrochemical sensors that may be exposed to harsh
chemicals, or in battery-operated devices that can develop internal explosive
atmospheres due to hydrogen buildup.

Mech- anical seal
Flowserve Corp., Dallas, Texas |
The QBQ LZ contacting-face mechanical seal features Precision Face Topography
and its patented wavy face seal design. The QBQ LZ provides high-reliability
sealing with low emissions and is a sealing solution for pumps in light
hydrocarbon service at low vapor pressure margins. Optimized for service
with light hydrocarbons of specific gravity between 0.40 and 0.60, the QBQ
LZ is designed for use in refineries and the general hydrocarbon processing
industry pumping ethane, ethylene, propane, propylene, butane, and other
related liquids. Light hydrocarbons present unique challenges for these
facilities because of their natural tendency to flash from liquid to vapor
at ambient pressure and temperature conditions. Vaporization leads to dry-running
of seal faces and premature seal failure, which results in the double failure
of not meeting emissions and reliability objectives. The QBQ LZ, a new model
of the Flowserve QBQ seal, addresses the problem of vaporization in light
hydrocarbon service at low vapor pressure margins by altering temperature
and pressure dynamics on the seal faces.

Welding partner
Valtra Inc., Pico Rivera, Calif. |
The high-performance Ground Hog clamp
was designed to solve the problem of inadequate grounding of the weld arc
in all types of welding applications. The Ground Hog prevents current restriction
by providing a large copper contact point, and sturdy, formidable clamping
pressure, which facilitates the transfer of electrical current in a full
circuit. According to the company, inferior clamps often fail to adequately
deliver the electrical current, resulting in the heating, failure, and destruction
of the clamp. The Ground Hog is an assembly of an insulated copperhead cartridge
combined with a Strong Hand pliers, or Strong Hand sliding arm clamp. The
strong clamping forces of both models (pliers, 465 lbs.; sliding arm clamp,
1,000 lbs.) give the Ground Hog a secure path for the electrical current.
To further ensure a complete arc, the Ground Hog controls the electrical
current by isolating the two most important points: the contact surface
and the transfer to the cable connection. The Ground Hog is rated at 500
amps.

Hardfacing products
Technogenia, Charlotte, N.C. |
In industries that use heavy-duty parts for mixing, grinding, or other techniques,
anti-abrasion protection is imperative. This manufacturer of hardfacing
products has developed a special tungsten-carbide powder known as Spherotene
that, when deposited on the tool's surface, provides anti-abrasion solutions
for various fields. The strong carbide particles are applicable by a welded-on
cast-nickel cord, thermal spray, special castings, or precision laser, providing
almost 10 times longer service life than does a more traditional chrome-carbide
hardfacing, according to the company. The tungsten-carbide hardfacing forms
a metallurgical bond with the base metal on the part to protect against
wear and impact. The Spherotene powders consist of spherical particles of
monocrystaline tungsten carbide that are extremely hard. The applicable
cords, Technosphere and Technodur, are reels of flexible, nickel-core wire
coated with Spherotene.
