Double-head screw polymer riser 4 inch

Description

ِِِDouble-head Polymer Riser

The most important factor in the quality of two-headed polymer riser is the standardity of threading and mechanical strength of the piece. Polymer riser thread is 100% uniform and in accordance with the standard.

Also, all mechanical and technical tests related to UPVC pipes including impact test, corrosion resistance, UV, etc. It is also done on the pipes produced.

Two-headed polymer riser pipes in classic sprinkler irrigation systems by connecting to automatic valves put sprinklers in a higher position than crops. These pipes also help to remove turbulence or flow turbulence caused by automatic tap dewatering from lateral. Removal of riser pipe reduces the uniformity coefficient of water distribution in the field. And then parts of the farm are not adequately irrigated. This reduces the yield and tonnage of the product.

In choosing the length of the riser, two points should be considered:

1- Maximum plant height 2- Minimum riser length according to sprinkler discharge, which is obtained from the diagram.

If the maximum plant height is higher than the ryzer length obtained from the diagram, we consider plant height as the minimum length of riser. Otherwise, the minimum length of the riser will be the values obtained from the chart. It should also be noted that choosing a riser with a length greater than the required amount creates problems such as increased wind blowing of water spraying droplets and difficulty in transportation. To meet the needs of irrigation systems, Vispar has produced polymeric riser pipes in custom lengths and pipe diameters of up to three inches, with a operating pressure of 6 bars and a strong thread in accordance with BSPT standard, which have the best production quality.
