Features

1. Excellent thermal insulation — Thermal conductivity λ＜0.02, and λ＜0.006 can be achieved for special requirements.
2. High strength — The pipe body adopts petroleum-specific steel pipe materials. By matching different steel grades and threads, it can meet the tensile and pressure requirements of wells from 100m to 6000m.
3. Good durability — The main material is consistent with the well itself. Petroleum tubular materials normally have a service life of 30–50 years. With surface treatment processes, the steel pipe can serve for more than 50 years.
4. Superior heat resistance — Adaptable to a wide working temperature range of -30℃ ~ 350℃. Custom special products can satisfy ultra-high temperature up to 500℃ or ultra-low temperature of -196℃.
5. Fast installation — Threaded connection enables rapid installation and maintenance.
6. Compact footprint — Coupling-free connection design is available, suitable for geothermal wells of various diameters and old well rehabilitation.
7. Energy-saving and eco-friendly — The insulation material is environmentally friendly with no pollution during manufacturing. Outstanding insulation performance minimizes heat loss, delivering an overall energy saving rate of 30%～70%.
8. Cost-effective — Custom-made for customers requiring downhole insulation pipes. Our unique factory equipment and technical capability effectively control the comprehensive cost per meter.
