In recent years, specialty metals such as titanium,
zirconium, niobium, and tantalum have been used increasingly in a wide
range of corrosion resistant applications. Typically, the chemical,
pharmaceutical, food, electronic and electroplating industries as well as
power stations and desalinization plants use these high performance
corrosion resistant metals cost effectively.
|
Efficient use of these metals can significantly reduce
overall cost. For this reason, SPF Co., LTD developed an exclusive
technology in an effort to utilize these metals in many of their
products. Conventional explosion bonding accomplishes some of the cost
saving objectives, however there are many
restrictions to the explosion clad product. The thickness of the
corrosion resistant material must be greater than .078" (often
.125") and the base metal, or structural component, must have
sufficient thickness to overcome the effects of the explosion.
Fabrication techniques used to manufacture explosion bonded products are
complicated, tedious, and troublesome.

SUN Z-R technology was developed in 1963 and is a unique seam braze cladding method which has overcome
many of the disadvantages of the conventional explosion bonding
technique. The SUN Z-R technology allows thin specialty metals
(.010" to .078") to be clad to copper, steel, aluminum, or
stainless steel regardless of shape, or thickness of the base metal. This
means that these specialty metals can be applied to columns, vessels,
reactors, sheets/plates, heads, tube sheets, pipes, tank trucks, or
almost any shape or size of structural component. The SUN Z-R lining can
be manufactured to withstand full vacuum and the consequences of severe
agitation. It is applicable to a wide range of applications. It becomes
obvious that the key advantage is the cost saving that is in place.
Whereas traditionally a "expensive"
solid specialty metal product was required due to corrosion resistance,
now it can be replaced with a "cheap" carbon steel product that
has been lined with the corrosion resistant metal. For instance where
before a 1" solid piece of titanium was required for pressure or
load, now it can be replaced with a .625" carbon steel piece lined
with .063" titanium.

 The SUN Z-R Process is
a proven technology that is used in many industrial applications. To date
no technology can match SUN Z-R's proven performance and track record.
The superiority of the SUN Z-R Clad technology has received noteworthy
acclaim.
In 1985, it was voted the Gold Medal Winner of the Titanium Association
of America's (now The International Titanium Association) competition for
titanium application. Recognition by other international professional
organizations is also noteworthy and is a result of SUN Z-R's exceptional
record of performance achieved over the past three decades.
Industry awareness of SUN Z-R accomplishments has dramatically increased it's use by the
petrochemical, specialty chemical, electrochemical, and plating
industries. In addition, it is gaining worldwide recognition in major
construction and engineering companies' written specifications.
