Apparatus for the chemical and electroplating industry

Lead has proven itself in chemical apparatus engineering due to its physical and chemical properties, particularly in corrosion protection, and is therefore used, among other things, in the production of pressure autoclaves. As a composite material, homogeneous lead lining combines the strength of steel with the excellent corrosion resistance of lead. It is used wherever high temperatures, pressure, or negative pressure do not allow for lead sheet lining. Automated homogeneous lead lining, introduced in 1972 and continuously developed since then, enables the economical production of large corrosion-protected equipment.
We manufacture components with diameters of up to 5.6 meters and weights of up to 130 tons. In addition, containers of any size in a homogeneous design are also manufactured on construction sites. The homogeneous lead lining is carried out and tested in accordance with DIN 28058. The necessary calculations, the correct choice of materials, and CAD designs are carried out professionally, taking into account all stresses caused by mechanical and chemical loads.
Inspection, repair, and overhaul of old systems Experienced and knowledgeable specialists prepare detailed inspection reports for your maintenance planning and carry out repairs and overhauls on equipment and filter systems worldwide.

Wet electrostatic precipitator

Homogeneous leaded filter systems are used in metallurgical and chemical plants worldwide. Due to their excellent mechanical stability and corrosion resistance, our filters have been operating successfully in many plants for over 25 years without the need for repairs. Especially for wet catalytic processes and high loads of sulphuric acid aerosols, electrostatic precipitators made of lead or lead and conductive plastics are also used to reduce H2SO4 emissions. Emissions can thus be reduced below the detection limit.

Precipitation system and emission electrodes

Due to consistent further development over the past years, we now manufacture all types of precipitation systems that can be used as spare parts or for revamping existing systems. From conventional plate filters to round and square tube profiles to our own developed octagonal cross-section. We adapt the shape and size of the emission electrodes (spray electrodes) to the different precipitation systems and customer requirements.

Dry insulation

To overcome all the disadvantages of the oil insulation of wet electrostatic precipitators, we have developed the dry insulation. This dry insulation is used worldwide and offers significant advantages. The dry insulation is practically maintenance-free, oil that could penetrate the wet electrostatic precipitator is not present and therefore there is no risk of an oil fire due to contamination.

Star tube cooler

Gas coolers in the form of star tube coolers have been manufactured at JL Goslar for decades. Such coolers are components of gas purification plants for metallurgical waste gases and are required for cooling process gases, e.g. in the production of sulphuric acid, in order to remove excess water from the gas and produce sulphuric acid in the desired concentration. Star tube coolers are provided in the cooling water area either with homogeneous internal lead coating or with a corrosion-resistant internal coating. Star coolers are shell-and-tube condensers made of lead. Lead offers excellent corrosion resistance to the action of weak acids. To improve heat transfer, the lead tubes are extruded with internal fins. The lead pipes required for this purpose with a star-shaped inner profile are produced at JL Goslar on an extruder press. The number of star tubes in the star tube coolers and the overall height of the star tube coolers can vary. This means they can be adapted to the amount of gas to be cooled. After production, the star tube coolers are subjected to a final pressure test. The experience of our customers proves the high efficiency, reliability and durability of these star tube coolers. At the end of their life cycle, complete recyclability of the materials used is ensured and is another good example of the sustainability of lead as a material.
