Pipe Bundles for Wet Electrostatic Filters in the Chemical Industry

The chemical industry uses wet electrostatic filters to remove pollutants, such as aerosols,fine particles and ash. Pipe bundles from STEULER-KCH are crucial components in theconstruction of wet electrostatic precipitators. In order to separate out the pollutants, they arefirst electrostatically charged within the pipes of electrostatic precipitators. This causes themto be deposited on the oppositely charged surface of the pipes and they are then collected inthe filter sump. Electrically charged plastic precipitation bundles are primarily used whereconventional materials cannot deliver due to insufficient resistance.

Our portfolio of services includes the design, production and installation of pipe bundles made from thermoplastic polymers, both with and without electrically conductive surfaces. We use modular designs that allow us to adapt the bundles to different component shapes and sizes, according to customer specifications. Our many years of experience make us the partner of choice for glass-fibre reinforced plastic (GRP) housings and pipes for irrigation systems and gas distribution.

Our pipes are mainly fabricated using the following thermoplastic materials:

  • Polypropylene (PP), adapted to be flame retardant
  • Unplasticised polyvinyl chloride (PVC-U), inherently flame retardant
  • Post-chlorinated polyvinyl chloride (PVC-C), inherently flame retardant
  • Polyvinylidene fluoride (PVDF), inherently flame retardant

We offer you professional support from an assigned contact person – from the initial consultation through to on-site installation. We provide you with detailed, customised advice on selecting the combination of materials best suited for your project, taking into account factors from the plant environment, such as the expected chemical, mechanical and thermal stresses and the plant’s geometry. Our consultancy service always includes a plausibility check regarding design and materials and comprehensive project support to ensure smooth and timely implementation – even for complex projects. We develop custom combinations of materials in close consultation with our customers from the chemical industry. Our after-sales service gives our customers the opportunity to share their experiences of completed projects, to learn about current product developments and if desired, to have previously installed products inspected and evaluated concerning their remaining service life.
