What type of pipe is required for workers applying cement, sand, and water texture through a pneumatic hose?

Answer :

For applying a cement, sand, and water texture through a pneumatic hose, use a durable hose with a 2.54 cm to 5.08 cm diameter, made of rubber or polyurethane, and rated for high pressure around 8.00×106 N/m².

Pipe specifications for applying cement, sand, and water texture:

  • Diameter: A recommended diameter is around 2.54 cm (1 inch) to 5.08 cm (2 inches) to ensure sufficient flow rate while maintaining manageable pressure.
  • Material: The hose should be made from a durable material like rubber or polyurethane, which can withstand abrasion and high pressure while being flexible.
  • Length: The length of the hose should be long enough to reach the working area but not so long that it causes significant pressure drops. A balance generally falls between 15 to 50 meters.
  • Pressure Rating: The hose must handle a high-pressure rating to match the pneumatic system's requirements, typically around 8.00×106 N/m² for cement applications.
  • Inner Lining: A smooth inner lining can help reduce resistance and prevent clogging, ensuring greater efficiency.
