bore casingVermeeren Bros and Irrigation Industries stock high quality Australia made (stainless) steel and PVC casings and can arrange manufacture to your specifications.

The cased section of any bore usually forms a lining or casing for a water bore drilled vertically into the ground and houses the pump, drawing water from the source aquifer to the pump and seals the aquifer from contamination from adjacent zones. In this application, resistance to crushing rather than internal pressure is the key requirement, so the primary consideration is pipe wall thickness for high stiffness.

For corrosive water, PVC, ABS, FRP, or stainless-steel casing provides the longest life possible. Because of the many and sometimes conflicting factors involved in selecting the most suitable casing material, the driller should consult with the manufacturer/supplier and bore owner before selecting the casing.

PVC

PVC is made for a wide range of uses including drainage and general water distribution. It can be made in a range of wall thicknesses and internal diameters. Some of the advantages of PVC include that it is:

  • Non-corrosive
  • Readily available in some sizes, particularly small diameters
  • Light and easy to handle and join
  • Inert

STAINLESS STEEL

A range of grades of stainless steel can be matched to soil water chemistry and temperature to provide a higher corrosive resistance than steel. As a material stainless steel is very durable and sturdy, offering both high collapse strength and high resistance to corrosion.

STEEL

Steel is a frequently used casing material because of its greater strength. When used as a casing it can be butt welded or screwed. Steel has the following advantages over other types of materials:

  • It is stronger than other materials
  • It can be pressure cemented to greater depths because of its higher collapse strength
  • It can withstand high temperatures
  • It is available in large diameters
  • It can withstand rougher treatment
