Linings

To prevent corrosion, protect against wear and promote sliding,as well as for ultra-pure media.

Linings and in-liners made from thermoplastics and ultra-pure fluoroplastics

Linings made from thermoplastics are used where metallic materials, rubber coatings or other coatings are no longer sufficient due to higher mechanical, chemical or temperature-related requirements, or in situations where ultra-pure media are to be transported.

Linings made from ultra-pure fluoroplastics withstand aggressive chemicals even at high temperatures in the chemical industry, the pharmaceutical or biochemical industry, the semi-conductor industry, the foodstuffs industry or environmental engineering. They withstand almost all chemicals, have high impact resistance and are suitable for temperatures of up to 260° C in constant or alternating use.

Designs:

  • Possible applications for linings made from sheet material laminated on one side, vacuum bonded and seal welded to metallic surfaces:
    - Linings for centrifuges in the chemical industry with 2.3 mm FEP guarantee very high chemical and corrosion resistance and protect the
    centrifuges against damage caused by solids
    - Linings for steel pressure vessels with E-CTFE offer a cost-effective and reliable solution with a long service life, as an alternative to
    highly corrosion-resistant metallic materials (nickel-based alloys).
  • Possible applications for in-liners made from composite materials with glass fibre reinforced plastic (GFRP) as the supporting laminate:
    - Storage tanks reinforced with GFRP with in-liners made from thermoplastic fluoroplastics for storing highly-aggressive liquid chemicals
    - Multi-stage scrubbing columns made from PP / GFRP
    - Ion exchangers made from PE / GFRP

Lining materials:

Thermoplastics

  • PE-HWU / PE-EL / PP / PVC

Fluoroplastics

  • PTFE / PVDF / E-CTFE / PFA / FEP / MFA

Duroplastics

  • Constructions reinforced with GFRP with in-liners made from thermoplastic (fluor-) plastics or GFRP coatings of metallic materials.Determination of the appropriate resins and fibres in line with the process specification.

Linings from bulk goods systems with the TIVAR® or QuickSilver® Systems

Operators of bulk goods systems expect their silos, hoppers, delivery lines and transport devices to provide a smooth flow of material with the lowest possible wear. This is where TIVAR® or QuickSilver® linings offer the ideal solution. They are characterised by their flow-promoting properties, wear-resistant surfaces and high impact strength. This prevents downtime caused by material deposits, arching, freezing on, funnel flow or corrosion.

Possible areas of use:

  • Delivery, transport and processing of construction materials
  • Processing and transport of hot asphalt
  • Production and transport of chemicals
  • Foodstuffs processing
  • Prefabrication or "on site" assembly: Angenstein AG delivers and assembles the lining material in the manner appropriate for the system.

The following options are available:

  • Lining of the system components and machines in the Angenstein AG workshops
  • "On site" assembly carried out by our experienced fitters
  • One-piece drop in-liners for self-assembly
