Microtube

Alwasail microtube consists of a very small diameter tubing. Flow is regulated purely by the length and diameter of the tubing. Weights or stakes are sometimes attached to the end of the tubing to keep it in place.

Micro–irrigation also called localized irrigation, low volume irrigation, low-flow irrigation, or trickle irrigation is an irrigation method with lower pressure and flow than a traditional sprinkler system. Low volume irrigation is used in agriculture for row crops, orchards, and vineyards.

Design Features & Specification

Alwasail LDPE pipes are manufactured from the virgin high-grade of Polyethylene resins.
LDPE – 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.
