Data sheet

Product information

The Fig. 351 and Fig. 352 strainers from Fromme Armaturen are robust, high-performance fittings for protecting piping systems and downstream components from contamination. With their Y-shape, large strainer inserts and high-quality cast steel construction, they are ideal for demanding applications in the energy, chemical and process industries. Both models comply with European standards and offer maximum operational safety at temperatures up to +400°C.

Special features

  • Y-shape for optimum flow conditions
  • Body made of cast steel GP240GH+N (1.0619)
  • Sieve made of stainless steel 1.4301 for high corrosion resistance
  • Temperature range: -10°C to +400°C
  • Nominal pressures:
    Fig. 351: PN40
    Fig. 352: PN16
  • Flanged connection according to DIN EN 1092-1
  • Face-to-face length according to DIN EN 558-1, series 1
  • With drain plug for easy maintenance
  • Optional: Holding device (davit) for covers from DN250
  • Various mesh sizes available (0.6 mm to 2 mm)

Advantages

Optional equipment: Heating jacket and leakage jacket for strainers

Our Y-strainers with angled seat can be fitted with a heating jacket or leakage jacket on request. This modification is the ideal solution for applications where temperature stability and additional safety are required.

Your advantages:

  • Heating jacket: Keeps media at the desired temperature, prevents crystallization or solidification of liquids. Suitable for steam, thermal oil or other heating media.
  • Leakage jacket: Additional safety for critical media and aggressive liquids. Protects the environment from unwanted leaks.
  • Choice of materials: Stainless steel versions (e.g. 1.4541 / 1.4301 or 1.4571 / 1.4404) for maximum corrosion resistance.
  • Customization: Production according to customer specifications, including connections for heating media and insulation.
  • Integration in SKID systems: ready-to-install solutions for complex process lines.
