Description
Design Features & Specification
- LLDPE pipes are manufactured from the virgin high-grade of Polyethylene resins.
- LLDPE – linear low-density polyethylene (Density = 0.930 g/cm3) virgin basic polymers.
- Both the above materials contain the choice of polymers and high-quality carbon black to get life under every working and weather conditions.
- Minimum 2% carbon black added for resistance to ultraviolet deterioration.
- Economical – Longer Filed Life. Very Strict Quality control.
- Available in a wide range of diameters, coil lengths, and working pressures.
- Manufactured as per as 2698.1 – 1984 (Type 30)
- Each material has its application field, attractions, and particular benefits depending on working and installation condition, equipment available, and personal preference.
Chemical Resistance:
Polyethylene is renowned for its excellent resistance to chemical attacks, but the degree resistance to a specific chemical will depend on concentration, temperature, and working pressure. Each of which will affect the life of any thermoplastic piping system.
Manufacturing Ranges of LLDPE Pipes:
- Nominal Sizes: 4mm – 32mm
- Working Pressure: 4.0 Bar at 20 Deg. C. (68 Deg. F)
LDPE Pipe Manufactured According to Australian Standard AS 2698.1 – 1984 Drip Irrigation Tubing (Type 30).
- Material: PE-LD
- Working pressure: 4 Bar at 20 Deg. C. (68 Deg. F)
- Color: Black
