Chapin™ - Twin-Wall™ –BTF Drip Tape

Features and Specifications

  • Manufactured from special grade virgin plastic using state-of-the art technology that guarantees the best results.
  • Precision formed flow path channels.
  • Large cross-sectional, hydraulically designed high vortex, turbulent flow-path that makes it a clog resistant drip tape.
  • Economical.
  • Off center slit outlets restricts water movement along the tape and ensures each drop falls to the soil.
  • Slit outlet, prevents entrance of the soil through outlet.
  • Lower tension while winding ensures less retraction in the field and avoids kinking.
  • Excellent CVm and emitter exponent makes longer length of run possible.
  • Minimum 100 micron filtration recommended.
  • Available in sizes of 16 mm (5/8”) nominal diameter.
  • Available in wall thickness of 0.1, 0.13, 0.15, 0.2 and 0.25mm (4, 5, 6, 8 and 10 mil)
  • Specially designed Tape Lock™ fittings are available. Please refer to ‘Poly Fitting & Accessories’ page.

Applications

  • Suitable for surface as well as sub surface installations.
  • Recommended for crops like cotton, banana, vegetables, sugarcane, potato, floriculture, strawberries, peppers, melons, etc.
