VARIAN VACUUM TECHNOLOGIES Company Profile:
Company’s brief description: Manufacturer and distributor of industrial vacuum pumps
interested in relocate the diffusion pump (vessels) production process to Romania in a
joint-venture partnership with a local manufacturer.
Technical requirements and information for building Varian vessels: Varian Vacuum
Technologies Company produces two types of vessels; these are large & small vessels.
A) First the large DP’s:
These are sizes 16" through 35" steel vessel with boiler plates welded on one end and a
flange welded on the other end. These vessels are round. They are wrapped with copper
tubing. The tubing is MIG welded to the steel shell with a silicon bronze welding wire.
The 16" vessel has an outside shell diameter of 16" and stands approximately 16" tall. It
has a flange welded on one end that measures approximately 24" in diameter. The shell
thickness is .375". The 35" vessel has an outside shell diameter of 35" and stands
approximately 72" tall. It has a flange welded on one end that measures approximately
48" in diameter. The shell thickness is .375". These vessels must be vacuum tight to 1x10
minus 9 torr and the copper tubing needs to be water tight at 90 PSI (We are willing to
help the supplier with these requirements).
The basic equipment required to manufacture large vessels is:
1) Powered rollers for rotating the shell and welding it to the flange and boiler plate.
2) Sandblast room large enough to house the 35" vessel. The sandblast room should be
enclosed and have a fresh air supply for the operator and a dust collector.
3) Powered tilt and rotate welding positioner large enough to hold the 35" vessel with its
flange bolted to its table.
4) Stud welding equipment capable of welding 1/2" diameter stud.
5) Spray painting booth capable of fitting a 35" vessel in the flange down orientation.
6) Paint baking oven capable of fitting a 35" vessel when placed on a wheeled cart
suggested minimum oven size is 6 feet left to right x 7 feet high x 8 feet front to back.
The operating temperature is 350 degrees F.
If the supplier does not have some of this equipment they can purchase it from Varian.
Other must have requirements:
1
1) Must have 15,000 to 20,000 square feet of manufacturing space with overhead crane
that they can dedicate to the Varian product line for continuous production.
2) Must have a staff of highly skilled welders, painter, tester, material handlers, and
packaging for the shipment of approximately 6 large vessels per week.
3) Will need money to invest for any equipment needed.
The manufacturing processes required to build the large vessels are:
1) MIG welding steel to steel
2) MIG welding steel to copper with silicon bronze alloy
3) TIG welding steel to steel
4) Silver soldering Copper to steel
5) Silver soldering copper to brass
6) Silver soldering brass to steel
7) Stud welding
8) Sandblasting
9) Painting
10) Pressure testing copper tubing
11) Vacuum testing the steel vessel (Varian to supply test equipment and instruction)
12) Pint baking (oven).
Vendor requirements:
1) Machine flanges up to 48" diameter
2) Roll shells up to 72" tall and 36" diameter
B) Now the small vessels:
The small vessels are produced in sizes 2" through 10". The 2" vessel is 2" in diameter
and stands approximately 6" tall. It has a flange welded to one end and a boiler plate
welded to the other end. The shell, boiler plate and flange are all stainless steel. It is
wrapped in copper tubing and has brass water fitting on the ends of the copper tubes. The
flange diameter is approximately 4". The 10" vessel is 10" in diameter and stands
approximately 24" tall. It has a flange welded to one end and a boiler plate welded to the
other end. The shell, boiler plate and flange are all stainless steel. It is wrapped in copper
tubing and has brass water fitting on the ends of the copper tubes. The flange diameter is
approximately 14". These vessels are manufactured in sizes 2", 4", 6", and 10". The shell
are typically .06" to .09" thick and are bulbous shaped and are produced in a hydroforming press.
The processes required and vendor requirements are very specialized. If a supplier can be
found to manufacture the large vessels then the supplier will need to purchase the
"special built" machines and equipment required to manufacture these small vessels.

It should be noted that the supplier will need approximately 5,000 square feet. An
overhead crane is not needed. It also be mentioned that the assembly and packaging of
the vessels will require an additional 5,000 square feet.
The heater is fully outlined in the attached PDF. The heater company should be a
company that produces product in a low volume, high variety fashion. Hence, Varian
Vacuum Technologies Company is not looking for a high volume company. It is looking
for a low volume company.
Jet assemblies are the key technology that drives the product as they are presented in the
photos attached. The jet assemblies and hence metal spinning are made of two alloys
these are 1100-0 aluminum and 304 stainless steel. The following list of machines is
required to manufacture the jet assemblies but, could be located at a subcontractor:
1) Metal Spinning machine large enough to spin 36" diameter 304 stainless steel that is
.125" thick.
2) Metal spinning machines small enough to spin 2" diameter 304 stainless steel that is
.09" thick.
3) Heat treating oven (full bright anneal) for annealing 304 stainless steel spinning that is
36" diameter (likely to be a subcontractor).
4) TIG welding of aluminum and stainless steel.
5) A method of cleaning the 304 stainless steel and 1100-0 aluminum spinning to make
them grease free.
Type of licensing or registration required in the USA: None
Related products that a local partner might also handle: None
Business objectives in Romania: Joint-Venture partnership with a local manufacturer
Preferences, technical qualifications, servicing capabilities, requirements or prequalifications that Romanian ideal prospects must have, English language ability,
size, coverage, investment etc.: The ideal partner is a medium sized pressure vessel
manufacturer with approximately $200,000 USD to invest. Must be bi-lingual.
Special features of the local partner’s operations, interests, or objectives in
Romania: Should have 20000 Square Feet of manufacturing space available with
overhead bridge crane, sandblast chamber, paint booth, and have highly skilled welders.
Preferred specific companies or types of companies to be contacted in Romania:
Pressure Vessel manufacturers, heating element manufacturers & metal spinning firms.
