1. Raw Material Preparation:
Selection of high-quality steel coils/strips (carbon/corrosion-resistant) to meet Construction welded pipe and water well standards.
2. Forming:
Precision roll-forming into cylindrical shape, ensuring dimensional accuracy for well installation and large diameter water pipeline compatibility.
3. Welding:
ERW or SAW techniques to create leak-proof seams—critical for maintaining well integrity and preventing groundwater contamination.
4. Sizing & Straightening:
Calibration for roundness and straightness, enabling smooth driving into diverse soil conditions across target regions.
5. Surface Treatment:
Application of galvanized, epoxy-lined, or polyethylene-wrapped coatings to resist corrosion from saline/acidic groundwater and harsh climates.
6. Threading (Optional):
Custom threading for secure joint connections in deep well projects.
7. Quality Testing:
Hydrostatic pressure testing, ultrasonic (UT) inspection, and corrosion resistance testing to comply with API 5L and ASTM standards.
8. Packaging:
Preparation for regional shipping with moisture-proof protection.
Superior Corrosion Resistance:
Coated variants (galvanized/epoxy-lined) and corrosion-resistant grades withstand saline groundwater, tropical humidity, and arid soil erosion.
Pressure & Load Bearing:
Engineered to handle subsurface pressures and installation forces, ensuring well stability in diverse geological conditions.
Safe Water Conveyance:
Leak-proof welded seams prevent groundwater contamination, meeting potable water standards (NSF/ANSI 61).
Versatile Applications:
Suitable for potable water wells, irrigation, geothermal systems, and dewatering—aligning with regional water needs.
Large Diameter Compatibility:
4"-24" range integrates with large diameter water pipeline projects for municipal/industrial water supply.
Cost-Effective & Durable:
As a construction steel pipe supplier, we offer long-lasting casing pipes that reduce maintenance and replacement costs.

RFQ Question: Do your water well casing pipes resist saline groundwater in coastal regions?
Answer: Yes, our epoxy-lined/galvanized API 5L Gr. B pipes offer superior saline corrosion resistance.
RFQ Question: Need large diameter (20"+) casing pipes for municipal water supply wells—are they compatible with water pipelines?
Answer: Our ASTM A53 Gr. B large diameter casing pipes (20"-24") integrate seamlessly with large diameter water pipeline systems. They’re corrosion-resistant, meet AWWA C200 standards.
RFQ Question: Are your casing pipes suitable for geothermal wells in temperature-fluctuating regions?
Answer: Yes, our ASTM A333 Gr. 6 low-temperature steel pipes withstand -45°C to 120°C fluctuations. They’re ideal for geothermal systems, meet API Q1 standards with technical support.
RFQ Question: Can you supply corrosion-resistant pipes for irrigation wells in arid, sandy soils?
Answer: Our galvanized ASTM A500 Gr. B pipes resist arid soil erosion and groundwater salinity. They’re durable for agricultural irrigation.
RFQ Question: What grade of casing pipe is best for potable water wells in tropical wet regions?
Answer: We recommend API 5L Gr. B with epoxy lining—resists tropical humidity and bacterial corrosion. It meets potable water safety standards, delivers in 15-20 working days, and includes corrosion test reports.
RFQ Question: Do your pipes support threading for deep well splicing (over 12m)?
Answer: Yes, our pipes are available with custom threading for secure deep well splicing. We use API 5L Gr. B for consistency, provide threading guidelines.
