Continuous Slot Wire Wrap Screens (Johnson Type)
The industry standard for sand control and well completion. Our wire wrap screens offer a unique V-shaped wire design that ensures maximum flow and prevents clogging in even the most challenging geological conditions.
Engineered for Superior Well Performance
A Wire Wrap Screen is manufactured by wrapping a cold-rolled V-shaped profile wire around a circular array of longitudinal support rods. This advanced welding technology ensures every intersection is fused for maximum structural integrity.
Our screens provide 2-3 times more open area than conventional slotted pipes, significantly reducing the entrance velocity of the fluid and extending the lifespan of the well and the pump.
Advanced Features
Non-Clogging Slot
The V-shape wire creates an inward-widening slot that prevents sand particles from getting wedged, ensuring continuous flow.
Maximum Open Area
Continuous slots provide much higher porosity, which reduces pressure drop and prevents pump cavitation.
High Collapse Strength
Precision-welded support rods allow the screen to withstand extreme downhole pressures at great depths.
Sand Control Expert
Designed to retain formation sand while allowing the fluid to move freely, optimizing well development. 8.
Diverse Applications
Water Well Drilling
For municipal, industrial, and agricultural irrigation wells.
Oil & Gas Wells
High-efficiency sand control for vertical and horizontal completions.
Wastewater Treatment
Used as intake screens to protect pumps and downstream equipment.

Frequently Asked Questions
This is usually determined by a sieve analysis of the formation sand. A common rule is to select a slot size that retains 90% of the formation material.
Stainless steel (304/316L) offers superior corrosion resistance, which is essential for wells with acidic water or long-term durability requirements.
Yes, we offer standard API threads (STC, LTC, BTC) and custom-machined collars to match your drilling string.
