DENSIT DSP TECHNOLOGy DENSIT wearflex, wearcast and wearspray The DSP technology Densified Systems with ultrafine Particles combines cement, microsilica and super plasticizer extremely tight, which leads to extremely low moisture content in the material. This ultra strong material is known worldwide as Densit Binder. The highly thick microstructure of Densit Binder results in a particularly high impermeability for chloride ions and a high electrical resistance. These two traits give the material, in addition to a particularly high corrosion resistance, an extraordinary durability against various stresses, such as abrasion. Normal cement structure Cement particle and water wc = 0.5 0.7 Super plasticized cement structure densit WearFlex Densit WearFlex is a material combination of high-strength binder and extremely wear-resistant ceramic additives. Densit WearFlex is produced as a normal temperature material (Max. 400 C consistent temperature) and as a high temperature material (max. 1,200 C consistent temperature. Densit WearFlex is used as mortar on an expanded metal substructure. Overhead mounts are also possible. Densit Binder s special characteristic is made clear in connection with its additives in a pressure test, for which a Densit test cylinder is used. The additives are so tightly incorporated that they break before the Densit Binder surrounding them. The DSP technology was developed by Densit and a patent for it was first applied for in 1978. It is the basis for the ultra thick structure of Densit materials and the key to their extraordinary attributes. Cement particle, super plasticizer and water wc = 0.3 0.35 DSP Technology Cement particle, super plasticizer, microsilica and water densit WearCast Densit WearCast is a material combination of high-strength binder and extremely wear-resistance additives.

DENSIT Cast BASALT densit ALUMINIUM OXIDe ceramic Cast Basalt is made from special quality natural basalt. The basalt is melted in shaft furnaces at 1,300 C and then poured into the desired forms. Cast Basalt is produced in form components. Essentially, this means sheets and pipe components. One of the most important processes in the production of Cast Basalt is the subsequent tempering during which the Cast Basalt forms a uniform crystalline structure that guarantees its high hardness and wear resistance. Due to its bargain price/performance ratio, Cast Basalt is a material often used in tribology protection. In addition to its wear resistance, Cast Basalt is characterized by its singular resilience with regards to almost all acids and bases. Cast Basalt surfaces remain permanently smooth and even while in use and thus offer the advantage of little caking. PRODUCTION The base product for the production of Aluminium Oxide Ceramic ist highly pure, synthetic (Alpha) Aluminum Oxide. Nowadays, due to weartechnical and economic reasons Aluminium Oxide is predominantly produced with a purity level of 85 92%. The standard quality of 90 92% has been established in the industry. A myriad of geometric forms are produced through compression or casting. Slip casting is used for extreme geometric shapes. The raw ceramic parts are baked at about 1,500 C. The ceramic parts are subsequently thick and without porosity.

Wear-resistant pipe components densit Pipe components Densit pipe components for pneumatic and hydraulic conveying systems Pipe bends, pipes, branch pipes or similar pipeline components often number amongst the most capable wear protection systems in industrial facilities. Densit disposes of more than 25 years of experience creating the optimal tribology protection system for you. Densit offers solutions for all wear protection media. Pipeline components with the following linings are available: Densit materials Cast Basalt Aluminium Oxide Ceramic Buildup welding Special materials Densit delivers pipeline components worldwide in all industrial fields. Construction of wear protected pipe components Worn out pipe bend repaired out of necessity Construction also occurs beginning with the desire nominal diameter of the pipeline system. Depending on the choice of wear protection lining, this results in an altered outer diameter for the pipes and the flange connections, which are adjusted to fit the system. Example of system construction Normal flange connection Connection with counter flange Connection with adapter flange Material selection: Before determining the appropriate wear protection material, Densit conducts a system analysis, the goal of which is to be able to offer the customer an optimal material selection. The material selection and the design of the individual pipe components always occur based on the project and thus are always compatible with the existing pipeline system. Sheet jackets: As standard material, the pipe components are made out of steel S235JR. Straight pipes, longitudinal weld or spiral weld. Surface preparation: Manual removal of rust or blasted SA2.5 Primer coat, primer 40 µ. connections: Straight pipe, standardized based on DIN 2576, PN 10, bilateral compact flange. Pipe bend, standardized based on DIN 2642, PN 10, bilateral coil and loose flange. In addition to construction, Densit also offers all internationally used flange connections such as ASME, BS, Victaulic or Viking-Johnson connections.

Pipes with DENSIT Lining PIPES WITH CAST BASALT LINING In contrast to other wear protection materials such as cast basalt or aluminum oxide ceramic, Densit materials are not installed in the pipework components as semi-finished products in the form of pre-assembled cylinders or sheet goods. Using a special core technology, Densit is poured cold directly into the pipe components. This produces advantages such as a caulk-free lining, the ability to have eccentric linings and inclusion of the tribology protection over the entire wall thickness. A high temperature resistance of 400 C completes the extraordinary attributes of pipework components lined with Densit. Cast Basalt is poured as a semi-finished product in the form of cylinders in the desired nominal diameter, with 20mm wall thickness and 500mm component length. Worldwide, cast basalt is the most often used wear protection material in piping systems. Due to its high wear-resistance, Cast Basalt is used everywhere where abrasive media are transported pneumatically or hydraulically.

PIPES WITH ALUMINIUM OXIDE CERAMIC LINING Aluminium Oxide Ceramic, as the hardest available wear protection material, is often used if the basic conditions in the pipeline systems are extreme. We close the circle of services for our customer! High delivery rate and speeds, powerful closing pumping media and tight wiring often lead to high wear rates, for which only the application of aluminum oxide ceramic leads an appropriate durability for the pipework. Even thin lining thicknesses result in increased durability. Aluminum Oxide Ceramic is mounted as a semi-finished product in the form of pipe cylinders or as sheet goods in various lining strengths in the piping components. Advantages: Extremely wear-resistant Variable lining thicknesses Low installation weight High durability Installation Maintenance and Support Site Measure PIPES WITH BUILDUP WELDING Design and drafting Buildup welding systems such as Densit WearPlates are effective in all respects as universally mountable wear protection even for extreme demands. In the past, pipework components had to be formed from iron sheets and painstakingly welded together in segments. Today, thanks to state-of-the-art robot technology Densit is able to directly provide pipes and pipe bends with buildup welding both inside and outside.
