We challenge the best available technology
"Innovation" is for us on the one hand the continuous further development and optimization of our current product portfolio and on the other hand the search for trend-setting new products and applications.
Examples of this are the new sealing concept of our SICABON® shell and tube heat exchanger, higher confirmed pressure rates of our FLUROFLEX® expansion joints or our new gasket free DIABON Groove heat exchanger (GVX).
Furthermore, we can support you with engineering and calculation in the development, analysis and optimization of your products and processes.
SICABON plate heat exchanger: Highest degree in modularity and flexibility
- New benchmark setting equipment solution
- Perfectly suitable for multi-purpose or pharmaceutical applications
- No interaction of SICABON with process products and no release of particles into the product
SICABON silicon carbide (SiC) is a ceramic material offering the widest range of corrosion and abrasion resistance. This, combined with its high thermal conductivity, makes SICABON an ideal material for heat exchange applications in the harshest and most challenging process conditions.
The plate package is modular expandable up to 2.6m² heat exchange area with individual parts of the complete heat exchanger available on stock for fast availability.
SICABON shell and tube heat exchanger: Unique sealing concept
- New benchmark in sealing concept
- Unmatched safety at maximum reliability
- Proof of tightness according to the technical instruction TA-Luft
SICABON heat exchanger significantly differ from all other designs available on the market due to the sealing technology for tubes inside the tube sheets. This unique and patented sealing system consists of two pressure-bearing tube plates, an intermediate plate made of solid SiC and special developed gaskets to ensure maximum operational reliability.
The new sealing system is available in all common nominal widths from DN100 to DN400 in standard with achievable heat exchange areas up to 34 m².
DIABON Groove heat exchanger (GVX): Gasket free heat exchanger
- ATEX Zone 0 applicable
- Standardized and modular construction
- Perfectly suitable for gas applications
Our new heat exchanger extends the SGL portfolio with two gasket free heat exchanger types achieving exchange areas up to 17 m².
All graphite parts of the DIABON groove heat exchanger are firmly cemented to each other, without internal gaskets and form a functional, self-contained graphite unit in which the process and service medium only contact our FDA-certified graphite. The use of only fully conductive main components also covers all criteria of Zone 0 according to 2014/34/EU.
SIGRABOND® Chemical feed tube:
Benchmark for ease of use and performance
- Easy handling realized by self-supporting lightweight design
- Non-sensitive due to mechanical stability of carbon fiber-reinforced carbon
- Increased flow rates due to wall thickness of only 2 to 5 mm
Feed tubes made of SIGRABOND Chemcial mainly are used as feed pipes, dip pipes and gas inlet tubes for corrosive applications.
The high freedom in design allows customized designs of openings in accordance with the hydraulic requirements. In addition, SIGRABOND Chemical feed tubes are available in all common sizes from DN25 / 1” up to DN250 / 10” in standard. Bigger diameters up to DN1000 / 40” can be designed and produced on request. The final length is defined by the specific customer application and can be up to 5000 mm in one piece.
For installation, SIGRABOND Chemical feed tubes are equipped with DIABON® collars to be placed between the flanges of the reactor and the piping. A PTFE-lined reducing piece is available on request.
DIABON burner tube:
Higher turbulences reduce H2 excess
- Improved conversion rates of Cl2 and H2
- 100 % graphite construction
- Higher resistance than glass based designs in case of wet feeds
- Homogeneous and stable flame across the full turn-down
Performance level and reliability decide about the profitability of HCl synthesis in operation. Beside the acid concentration or gas quality, the necessary excess in H2 for full Cl2 conversion has to be taken into account.
The new inner burner tube was developed exactly to meet these requirements. Improving the conversion rate of Cl2 and H2 by higher turbulences, the excess of H2 in many cases can be reduced drastically. The 100 % DIABON design in addition reduces the risk of damages by flaking especially if wet feeds cause droplets hitting the burner tube.
Of course, options like the burner flushing device are still available for both feeds.
FLUROFLEX expansion joints:
Only facts provide safety
- No risk of expansion joint failure due to design error
- No overloading due to incorrect extrapolation of pressure rating
- Validated and certified by TÜV
Operational safety is the most important factor in operating processes with critical media. Only proven and certified product skills can fulfill this basic requirement without having doubts.
With FLUROFLEX bellows, SGL Carbon is offering products including the ability to confirm performance parameters at specific design temperatures across the full standard product range.
FLUROFLEX expansion joints:
Carbon fiber-reinforced carbon vacuum support ring
- No risk of corrosion of vacuum support rings due to diffusion
- Extended range of applications – resists where others fail
- Retrofit and removable
Current solutions of vacuum support rings for expansion joints mostly are based on welded rings made of exotic metals with PTFE-lining. These rings have to be installed by the OEM and cannot be removed non-destructively.
For the first time, FLUROFLEX expansion joints can be offered with segmented vacuum support rings fully made of corrosion resistant carbon fiber-reinforced carbon (CFRC). The vacuum support rings can be installed and removed easily by a snap fit. The risk of corrosion due to diffusion and therefore the risk of failure is minimized.
In addition, SIGRABOND Chemical vacuum support rings extend the range of possible applications based on the superior corrosion resistance of carbon.
