Alwasail PC drip line is an advance, pressure-compensating, linear low-density polyethylene drip line. The cylindrical flow-regulated inline emitters are self-contained units molded at specified intervals into the inner wall of the polyethylene tubing. Each has a self-cleaning mechanism at the water outlet chamber. Both the tubing and the droppers are manufactured from the most excellent quality resins to ensure uniform watering from each emitter, year after year.

Chemical Resistance:
Polyethylene is renowned for its excellent resistance to chemical attacks, but the degree of 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 LDPE Pipes:

Alwasail LDPE Pipe Manufactured According to Australian Standard AS 2698.1 – 1984 Drip Irrigation Tubing (Type 30).

Manufacturing Standard:
All low-density Polyethylene pipe supplied by Alwasail is made per Australian Standard AS2698.1 – 1984f
Pipe Color:
The color of the Alwasail LDPE pipe is black primarily to provide high protection against degradation due to UV radiation. There is no limitation in the external use of PE pipes as they are designed to withstand continuous solar radiation for over 50 years at least.

FEATURES :

  1. Flow-regulated, self-flushing inline emitters deliver equal flow at a wide range of operating pressures.
  2. Flow uniformity regardless of operating pressure and variations along the line
  3. The dripper and the diaphragm are self-contained units that are molded to the interior wall of the tubing
  4. Turbulent flow through a large labyrinth water passage helps reduce clogging
  5. Made of three (3) individual sections including a cylindrical plastic housing with a labyrinth water passage, a floating silicon diaphragm, and a plastic receptacle
  6. Resistant to chemicals and fertilizers commonly used in landscaping
  7. Flexible tubing for easy installation
  8. The emitter's performance is not affected by changes in water temperatures at 20 C
  9. Resistant to clogging
  10. Large pressure compensation range up to 4.3 bar.
Design Features & Specification
  1. Alwasail LDPE pipes are manufactured from virgin high-grade Polyethylene resins.
  2. LDPE – linear low-density polyethylene (Density = 0.930 g/cm3) virgin basic polymers.
  3. Both the above materials contain the choice of polymers and high-quality carbon black to get life under every working and weather condition.
  4. A minimum of 2% carbon black was added for resistance to ultraviolet deterioration.
  5. Economical – Longer Filed Life. Very Strict Quality Control.
  6. Available in a wide range of diameters, coil lengths, and working pressures. 
  7. Manufactured as per 2698.1 – 1984 (Type 30)
  8. Each material has its application field, attractions, and particular benefits depending on working and installation conditions, equipment available, and personal preference.
