“MANUFACTURING EXPERTISE

We develop products for the highest standards – we set standards
with our surface treatment.

”

Surface Treatment
Treatment of inner surfaces for high purity
We have decades of experience in mechanical and electrochemical surface treatments and finishes and we offer optimal quality for high purity industrial applications. In addition to standard fittings and tubes, we
also finish complex special components such as manifolds, CIP lances andbubblers. The spectrum of treatments ranges from staining to mechanical processes to ultra pure electrochemical polish. This 380 x magnification illustrates the differences between the surface treatments:

Benefits of Surface Treatment• optimal inner surfaces
for high purity processes• increased resistance to corrosion• improved cleanability of the system• reduced adhesion of particles due toextremely smooth surfaces

electropolished}In anodic processes, the material is cleaned with a stripping force of 3 to
5 µm. The material stripping is significantly higher for the electropolishing process: which is up to 20 µm.

Collaring

Benefits of Collaring Technology

We know how
The collaring of T pieces, CIP lances or manifolds is well-developed
Dockweiler know-how. Closely-spaced branches often pose a technicalchallenge. This is routine for our specialists. In combination with our welding
expertise, products are created which are characterised by a particularlycompact and flow-optimized construction. Included in this are excentricbranches and branches with various angles (for example, T-pieces with45 degree branches).

• homogeneous transition contour
from the main tube to the branch tube
• streamlined flow behavior• effective welding preparation• complete reduction in space forexample in the production of manifolds• compact component geometry

Helium leak testing• residue-free cleaning• particle-free packaging• from production to packaging:
everything takes place in a selfcontained work process

Benefits of Welding Technology• 3D internal orbital welding technology

branches• machine-controlled TIG processes• 100% weld seam testing• straightforward documentation withcomputerized processes

6High purity environment for high purity products
For products which are used in the semiconductor industry, production
must take place in a high purity environment. There must be no contamination from foreign particles or residues. These conditions are only possible
in the cleanroom. High purity products such as manifolds or Bubblers are
welded, assembled, tested and packaged in the cleanroom.
For the most exacting requirements in cleanrooms, we rely on highly trainedand experienced specialists. A high level of discipline and forward-thinking
are among the demands we make of our employees. Regular training andfurther development in the area of cleanroom production ensures a highstandard of product quality and thus your process reliability now and in
the future.

Welding Technology
Decades of experience in cutting-edge technology
Dockweiler is a pioneer in the area of orbital welding. With the 3D insideout welding technology (IO welding) we have developed new andexciting opportunities for innovative production capabilities. In thisway, closely-spaced branches and those with lower dead space are produced in a highly-efficient manner. This 3D internal orbital welding technology is ideal for complex geometries and innovative components.

Cleanroom Production

3D Bending
Fewer weld seams for more reliability and purity
With our 3D bending technology, we are in the position to reduce thenumber of welding seams to a requisite minimum. This is particularly
advantageous in complex tube systems.
Along with our collaring expertise and our welding know-how, we
produce space-saving and dead-space-optimized solutions for custom
applications.

Benefits of 3D Bending Technology• minimization of weld seams for aspectsof hygiene and safety• CAD-construction and automatic
production• 3D measuring technology anddocumentation• mid-process inspection for quality
assurance

PRODUCTS FOR HIGH PURITY PROCESSES

Flextron – the “flexible” stainless steel tube
The Dockweiler Flextron corrugated hose was developed for the semiconductor and fine chemical industries. The highest demands are placedon the purity of the process media in these industries. Flextron's electropolished inner surface allows for these requirements to be met in all aspects of the supply system - wherever a flexible connection is needed.
Flextron is manufactured from mechanically corrugated stainless steel(1.4404), as standard. An additional braid of stainless steel wire ensures ahigher pressure resistance and protects the hose from damage. The unique
combination of an electropolished surface and a flexible corrugated hoseminimizes the risk of contamination and enables gas transport under full
UHP conditions throughout the system. With Flextron, oscillations andvibrations can be decoupled and done to the highest purity standards.

CUSTOMIZED SOLUTIONS

Customized solutions for the semiconductor and high-tech industry.
Dockweiler is one of the pioneers among the suppliers of UHP conduit systems. Since the introduction of PC‘s in theearly 80‘s, the company has been developing and producing UHP tubing and fittings for the semiconductor industry.
Today, Dockweiler offers components for all UHP media and processes: From thick-walled UHP tubes to prefabricatedclean room manifolds. Options for flexible connection of ultra-pure gases, UHP process vessels as well as dead-spacefree connection systems round off the product range.

Prefabricated manifolds
Prefabricated manifolds for UHP installations
Manifolds for utility lines are designed to simplify all UHP installations.
Manifolds are necked out and then welded, tested and packaged in an ISO
14644-1 Class 4 cleanroom. The use of prefabricated manifolds reduces theoverall installation and acceptance process of the system through faster
purge time and reduced particle count.

Benefits:- customized and efficient solutions
for the semiconductor industry- 100% helium leak tested:
1x10 -9 mbar l / s- Orbital welds for highest quality- 3D data for design planning- worldwide and fast delivery

Process Vessels
Double safety for the semiconductor industry and fine chemicals
Dockweiler process vessels for the semiconductor industry and finechemicals ensure double safety when handling organometallic compounds: On the one hand, their design guarantees “process safety“ when
feeding ultra-pure media to critical manufacturing steps such as metalorganic vapor phase epitaxy (MOVPE), a manufacturing process for sensitive opto-electronic components. On the other hand, the process vessels
offer an additional plus in safety due to their absolute tightness (helium
leakage rate ≤ 4.0 x10-9 mbar l s-1) and robust design.
Dockweiler process vessels are manufactured to the highest manufacturing and quality standards: From melt specification to careful orbital welds
and perfect electropolishing. Thus, the high-quality workmanship of thevessel ensures an optimal enrichment process, ideal utilization of the medium, best possible emptying, cleanability and reusability.
