ALUMINUM FITTINGS FOR STEEL AND PLASTIC PIPES
You can think of aluminum fittings when weight savings and performance at low temperatures are essential. Aluminum as a base material is ideally suited for light weight connections, in addition, it is strong, chemically resistant, conducts heat very well, and is widely available in the market.
In order to make aluminum suitable as a material for mechanical components, they are often anodized during manufacturing processes . Anodizing creates an extra hard surface and thus a more solid construction. In addition, the threads are often coated with PTFE for smooth mounting the individual components.
- Lightweight and low maintenance.
- Good heat conduction.
- Strength increases at lower temperatures.
- Can not be combined with other metals.
- Anodized parts are electrically non-conductive.
- Above +100 ° C the material weakens considerably.
WHEN is ALUMINUM A GOOD ALTERNATIVE TO BRASS, PVDF OR STAINLESS STEEL?
- Saving weight:
Aluminum couplings, fittings, manifolds and pipes are slightly heavier than PVDF versions but can withstand more pressure. (Good strength / density ratio) Compared to steel and brass you may save up to 70%.
When thermal conductivity is a critical point, aluminum delivers the optimal performance. (λ-value of 237 W/mK)
- Extremely low operating temperatures:
At extremely low temperatures, aluminum is also a good alternative. The strength of aluminum will increase when the temperature drops. (Limit Serto program -196 ° C). Aluminum is not an option above +120 ° C.
APPLICATIONS FOR ALUMINUM COMPONENTS
- Cooling systems
Aluminum fittings, pipework and manifolds are often applied in cooling systems where electric power is cooled with liquids. This has to do with the excellent thermal conductivity of aluminum.
- (Pneumatic) connections in transport sector
Wherever weight reduction is a critical point and was directly translate into cost savings on energy consumption.
- Cryogenic systems
Systems which work with (liquid), cryogenic gases, and thus operate under extremely low temperatures.
Application with extremely low operating temperatures.
Weight reduction in process lines in robotics.
Weight reduction in process lines of transport.
THE ALUMINUM (AW-6082) PROGRAM OF SERTO
The well-known metal-to-metal seal principle of Serto allows radial (de) mounting on drawn aluminum pipes and plastic pipes. The compact design with minimal seperated components and minimal risk of electrochemical corrosion makes this program an ideal complement to the existing program.
In terms of design have made a few minor changes as compared to the Brass M program:
- The thread of the body is slightly beveled for easier installation.
- The bore diameter of the body corresponds to inner diameter of the connected tube or hose.
- The ferrule is slightly shorter.
Teesing offers the opportunity for:
- complete hose assemblies.
- pre bent aluminum tubes with premounted fittings
- complete systems for filtering, distributing and transporting coolants.
Thread varies in a lot of different ways. Here you can read about the basics of thread.
Aspro-Teesing Industrial Systems produces locally the first 115-4RE CNG compressor for ENN.
EXMAR has been scoring points with a new DNV-approval (Det Norske Veritas) that verifies full functionality at pressures up to 800 bar (for 4x safety), hence certifying suitability for shipbuilding.
