PE Well Casing Pipes
Polyethylene casing in water wells
After drilling, well casing holds the borehole wall against collapse. Polyethylene well casing (Product P007) is plain, unslotted pipe.
Unlike carbon steel casings that suffer rapid electrochemical corrosion and encrustation, high-density polyethylene provides total chemical immunity and sustained hydraulic cross-sections in subterranean aquifers.
Well casing diameter, wall thickness and bar length (P007)
Well Casing Pipe (P007) is supplied in outside diameters from 110 to 500 mm and in 6 m and 12 m straight lengths. Casing diameter follows the drilled diameter and the pump size.
Structural resistance to external hydrostatic collapse pressure is the defining criterion when choosing casing wall thickness.
Installation and ordering
Casing bars are joined before entering the well and lowered slowly and centrally into the borehole. The jointing method is agreed at quotation according to diameter, depth and the drilling contractor's equipment.
For a quotation, enter well depth, drilled diameter and the length you need in the inquiry form.
Choosing PE well casing pipe
Well casing holds up the borehole wall and keeps the way open for the pump and the riser pipe. The diameter follows the drilled bore and the pump size, and the wall thickness follows the depth of the well and the soil pressure around it; deeper wells need a thicker wall.
Polyethylene does not rust and lasts longer than steel in saline or corrosive water. Before ordering, ask the drilling contractor for the well depth, the drilled diameter and the pump size, and send them to us with the length you need.
PE Well Casing Pipes — Frequently Asked Questions
What are the advantages of PE well casing over steel casing?
Polyethylene casing will not rust or suffer galvanic corrosion in saline waters, maintains smooth surfaces resistant to mineral encrustation, and its lighter weight simplifies borehole insertion.
Is the PE well casing slotted?
No. The PE well casing we supply is plain and unslotted.
How is casing wall thickness chosen?
It depends on well depth and the surrounding soil and water pressure; deeper wells need thicker walls. The diameter and thickness combinations are in the product's specification table.
Is PE well casing better than steel?
Polyethylene does not rust and is lighter, so it lasts longer in corrosive water; the final choice depends on the depth and conditions of the well.
