Irrigation Pipes Prices In Kenya

Irrigation pipes prices in Kenya by Grekkon Limited are for various pipe types, sizes, and thicknesses. In this article, we explore these factors, and also address most commonly asked questions on irrigation water pipes

I. What Type of Pipe Is Used For Irrigation?

Grekkon Limited’s irrigation pipes prices in Kenya are based on the following specifications

1. Irrigation pipe type by material

We supply and install high density polyethene pipes (HDPE), polyvinyl chloride pipes (PVC) for both surface, canvas delivery pipes and pre-perforated drip irrigation pipes and sub surface irrigation systems. The choice between these two pipes depends on the pipe placement and cost. HDPE pipes are for both surface and subsurface use. They can remain on the surface without being degreded the tropical sun’s high radiation because of the anti-UV treatment in them. PVC pipes on the other hand should be subsurface because they easily degrade under the sun, for the reason that they have no anti-UV treatment.

HDPE pipes are a popular choice for irrigation in Kenya, but are more expensive. Farmers who lease land over a defined period can lay them on the surface and dismatle them for use elsewhere at the expiry of the lease term. However with PVC, you cannot re-use them because they will be buried, and glued to each other

 

 

 

 

 

 

 

2. Pipe size

This is the internal diameter of the pipe. The larger it is, the more expensive the irrigation pipe is. Our HDPE and PVC irrigation pipe sizes are; 16mm, 25m, 32mm, 40mm, 50mm, 63mm, 75mm, 90mm, 110mm,125mm, 140mm, 160mm, 180mm, 200mm, 225mm, 250mm, 280mm, 315mm, 355mm, 400mm, 450mm, 500mm 560mm, and 630mm

An irrigation pipe’s internal diameter dtermines the volume of water it evacuates. A grower with 100 acres under irrigtaion will have larger pipes than one with an acre of similar crop. This is because more water is needed for the larger acreage

 

 

 

3. Pipe thickness

Pressure nominal (PN) is the universal measure of the pressure holding capacity of an irrigation pipe. The thicker the walls, the gretaer the PN rating, and the higher the pressure withstood by the pipe. A grower whose water flow is by gravity will have a lower PN rated water pipe than one with a high pressure water pump. High pressure in a thin walled pipe casues it to rapture or collapse. The choice of the water pipe’s pressure rating must be measured against the anticipated flow pressure. If for example your water pump has a head of 100M or 10 bars, then your water pipe will be from PN8 thickness

Grekkon Limited’s irrigation pipes for sale in Kenya PN ratings are; PN6, PN8, PN10, PN12.5, PN16, PN20, and PN25. For PVC pipes, our thickest pipes are PN 16

III. What Is The Standard Irrigation Pipe?

In Kenya, the 32mm or 1″ diameter PN6 thickness HDPE is the most commonly used irrigation pipe. This is because it irrigates small land parcels, which is what most farmers have

 

 

IV. Which pipe is best for irrigation?

This is a factor of the following:

• Land ownership type. If the user ows the land, then PVC or HDPE pipes will be buried permamnently. If it is on a short term lease and the grower wants to take back the pipes, then surface pipes like HDPEs and delivery pipes are suitable
• Budget. Delivery pipes are the most expensive per unit, PVC pipes are the cheapest
• Water quality. Where the water is saline and corrodes easily, polyethylene pipes are preferred to GI pipes
• The irrigation method. Rain hose pipes are different from drip irrigation pipes

V. What type of pipe is commonly used in irrigation?

In Kenya today, HDPE pipes are the most commonly used irrigation water pipes because they are easier to re-use than PVC pipes, and can be laid superficially on the ground. However, HDPE pipes are more expensive

 

VI. Why are PVC pipes used in irrigation?

They are robustly built to withstand high pressure flow in the pipes. In boreholes, PVC pipes are installed where mild steel casings will not work well

 

VII. How deep should PVC pipes be buried?

From 6″/ 15cm to 18″/ 45 cm in a farm where the former is in a location where it will not be in contact with a shovel blade, and the latter  here ploughing is to be undertaken

 

 

VIII. How do you install irrigation pipes?

Step 1. Make the planing beds, or planting holes a,d trenches (if the pipes will be buried)

Step 2. Connect the main line to the water source

Step 3. Connect the filter (for drip irrigation systems)

Step 4. Lay the main pipe in the trench

Step 5. Create hydrants

Step 6. Conncet the pipe to the irrihation system (sprinkler, rain hose or drip)

 

IX. What size should an irrigation main line be?

It depends on the farm size, which determines the amount of water needed. The larger the farm, the greater the water demande, and the larger the main line is. A grower with an acre of land will have a 1-1/2″ / 50mm or a 1-1/4″ / 40mm main line. Another framer with 10 acres will have a 3″ or 90mm

 

X. Do bigger pipes reduce pressure?

The larger the pipe diameter, the lower the resistance to flow, and hence the water pressure decreases
