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.

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.
