We provide specialized services for Johnson Screen Tubes, covering technical consultation, custom manufacturing and quality inspection. Our service focus is to ensure that each screen tube is properly selected and manufactured according to real well conditions, helping customers achieve stable sand control and long-term groundwater production.
Johnson Screen Tubes are commonly used in deep water wells, municipal water supply systems, and industrial groundwater projects. Because well depth, formation characteristics, and water quality vary from project to project, professional service support plays a key role in product performance and service life.
Our service begins with technical consultation at the project planning stage. Based on available geological data and operating requirements, we assist customers in selecting suitable screen parameters.
Engineering support includes:
Slot size recommendation based on formation grain size
Material selection for corrosion resistance and strength
Structural strength evaluation for deep well installation
Open area optimization to reduce head loss
Design confirmation before production
This service helps minimize risks related to sand intrusion, clogging, and premature screen failure.
Johnson Screen Tubes are manufactured using continuous V-shaped wire wrapped around longitudinal support rods, with each contact point resistance welded to form a rigid structure. All products are manufactured according to confirmed technical drawings.
Custom manufacturing options include:
Tube diameter and section length
Slot size range for different sand conditions
Threaded, flanged, or welded end connections
Stainless steel grades such as SS304, SS316, or SS316L
Surface finishing based on groundwater conditions
Each manufacturing step is controlled to ensure consistent slot accuracy and structural integrity.
Quality control is integrated throughout the production process. Raw materials are inspected before fabrication, and finished screen tubes are checked against agreed specifications.
Inspection items include:
Slot size and uniformity measurement
Welding quality and joint strength inspection
Dimensional tolerance verification
Visual surface inspection
Material traceability control
Only products that meet internal quality requirements are released for delivery.
Our Johnson Screen Tube services are designed to support reliable well performance over the long term. By combining engineering support, controlled manufacturing, and consistent quality inspection, we help customers reduce maintenance requirements, improve water production efficiency, and extend the service life of their wells.
