Features of Johnson type screen casing pipe,
1) Johnson type screen casing pipe are considered the standard of the industry, combining proven performance with durability
2) Low-carbon, galvanized or stainless steel construction
3) Provide optimum well development and access to the aquifer
4) Large open area:.
5) Water enters at lower velocity, reducing screen surface erosion and encrustation
6) Designed and constructed to operate under different depth conditions, with the optimum strength / open area ratio
7) Other installation depth designs available upon requests
8) Non clogging: is self-cleaning and ensures an uninterrupted flow. Sand grains make only two point contact and don’t wedge in the screen’s inwardly enlarging slot.
