FIELD POLY PIPE IRRIGATION
FOR TYPICAL LEVEL GRADE FARMING

• Armin, a leading manufacturer of agricultural and horticultural plastics, uses only the finest
• Armin's use of the latest technology ensures Poly-Pipe's performance against the elements, especially the sun's harsh ultraviolet rays.
• Along with this strong commitment to quality, you receive the most cost effective irrigation system available next to, of course, Mother Nature.

How Armin Poly-Pipe brings your irrigation costs down to earth

• Eliminates costly main ditch cutting and the need for dams on small grade changes.
• Eliminates labor intensive hand priming of siphon pipe.
• Eliminates 24 hour vigils searching for breaks in water soaked banks.
• Reduces water costs by ending loss through evaporation or percolation.
• Increases productivity by allowing you to irrigate where you want, when you want.
• Less friction allows water to travel farther without boost.
• With careful installation, retrieval and storage, you can use Poly Pipe for several seasons.
• Dry headlands permit easy access to all gates for precise adjustments and optimum control over water flow.

Poly-Pipe flexible field pipe is primarily designed for use with typically level grade farming. It will not transfer water over hills or upgrades / up hills. Most standard headlands are level or have a slight or small downgrade and are perfect for Poly-Pipe. Minimum Order 9 Rolls.

Installation Instructions

POLY-PIPE is primarily designed for use with level grade farming. It will not transfer water over hills or up grades. Most standard headlands are level or have a slight downgrade and are perfect for POLY-PIPE.

Restrictions for sloped headland (more than 2' per 1000' drop)

Headlands with downgrades of more than 2 feet per 1000 feet may need intermittent restriction in the POLY-PIPE line to assure even water flow to the crop rows.

Be sure you have sufficient waterhead (Level or Slight Grades)

Head is the WATER SURFACE HEIGHT ABOVE GROUND LEVEL. At least 6 inches of head is required for water to enter smoothly into the tubing and transfer across level or slight downgrade headlands.

Pressure relief vents

The use of an open-topped air vent is advised at the connection point of the tubing. The vent allows excess trapped air to escape, thus, avoiding burst damage in the tubing. On long tube runs. pressure relief vents are required to avoid damage to your tube.

Pump water source

Most irrigation tube installations should include placement of an air vent 10 feet from the discharge pipe as well as on high spots

Operation

Begin with a small water flow and gradually increase to a full rate. As the POLY-PIPE tubing is filling (starting from the intake end of the tubing) punch gate holes or install adjustable gates as required. Consult your local dealer or county agent for recommended flow rates for your soil type and conditions.

The gate holes or adjustable gates should be installed between the 2 and 3 O'clock position.

NOTE : These instructions are general and act only as a guide for installation. Due to environmental and field condition variance, some steps may not apply to your particular operation.

Connection Instructions

A. CHECK SIZE & SURFACE OF PIPE The diameter of the discharge pipe must correspond or be smaller than the POLY-PIPE that is to be attached. Rough or sharp edges should be smoothed or taped before the connection.
B. FOLD BACK TUBING Cuff approximately 1 foot of POLY-PIPE no to itself to form a double thickness over the pipeline. Secure with a hose clamp.
C. GIVE SUPPORT TO TUBING Make sure the connection is at ground level or supported with dirt so the POLY-PIPE does not hang off the connection. Slack should be left at the water source to keep the tubing from pulling off the connection.

Tube Laying Instructions

D. EASE INITIAL STRAIN ON CONNECTION To ease the initial strain on the discharge connection, have someone hold the tubing until the pulling tension is no longer there.
E. TRENCHING POLY-PIPE must be laid evenly in a continuous trench, 50% of the tubing diameter in depth and 100% of the diameter in width. The trench prevents the POLY-PIPE from rolling when filled with water.
F. 90o TURNS POLY-PIPE is flexible enough to complete a 90 degree turn with a 6 to 8 foot radius. Be sure trench radius is even on all corners.
G. KEEP TUBING IN PLACE A shovel of dirt every 15 to 20 feet will keep the tubing in place during installation as well as maintaining proper tension for smooth unrolling of the tubing
H. TUBE END For irrigation, the open discharge end of the POLY-PIPE tubing should be placed over a berm approximately 3 feet in height. This will prevent a buildup of excess pressure in the tubing and avoid damage to the system.
I. DO NOT TIE TUBE END The eventual pressure buildup will burst the tubing.
J. VENTING Improper venting is the most frequent cause of problems. If air builds up in the pipe it will restrict water flow and drive up pressure. An open top vent located about 10 feet away from the water source is best. Additional vents will be required at high spots.These are usually just gates punched into the top of the tubing.
