- Available geometries: Standard, Barrier, Maddock, Pineapple, Vented and Static Mixer designs.
Single Barrel
PENA bimetallic and nitrided barrels are engineered to provide maximum wear resistance, dimensional accuracy and thermal stability.
Manufactured from premium alloy steels and enhanced with Ni-Cr-WC or Ni-Co bimetallic linings, they deliver exceptional service life, even when processing highly abrasive or corrosive materials.
Technical Advantages
- Perfect metallurgical bonding between the lining and base steel.
- Uniform thermal control, reducing distortion and improving process stability.
- Consistent hardness throughout the barrel length, combined with excellent thermal conductivity.
- Outstanding geometric stability under internal pressure.
- Fully compatible with PENA 160, PENA 172 and PENA 175 screw technologies.
Technical Specifications
- Available diameters: Ø18 mm to Ø450 mm.
- Unlimited L/D ratio capabilities.
- Base material: Nitrided, hardened or stainless steel.
- Available with electric heating systems or internal cooling channels.
- Complete repair, refurbishment and rebuilding services available.
