- Slots are made on base pipes with large ID/OD ratio.
- High mechanical strength, high flexibility to allow adequate bending, which makes it applicable in complicated well conditions, and can be used in open-hole horizontal well completion for sand control.
- Low cost in manufacture and downhole installations.
- Open hole area: 2%-6%.
- Base pipe: J55, N80, P11 0, etc.
