DOUBLE WALL SEGMENTAL CASING
Double-wall casings consist of two layers of steel, with a gap & filler material between them,
providing higher strength and torsion resistance.
Advantages:
- High Strength: The double-wall structure makes these casings more durable, allowing them to perform well under high torque and in difficult geological conditions.
- Durability: Double-wall casings are less prone to deformation or damage in hard rock formations or gravel layers, offering longer service life.
- Better Torsion Resistance: They can transmit the rotary torque more effectively, ensuring stable performance during drilling.
Application:
Ideal for complex geological conditions, such as hard rock formations or gravel layers, and deep drilling operations that require high strength and durability.

SINGLE WALL SEGMENTAL CASING
Single-wall casings are made from a single layer of steel and are typically used in simpler geological conditions.
Advantages:
- Lightweight: Due to their single-layer structure, single- wall casings are lighter and suitable for shallow or soft soil drilling operations.
- Lower Cost: They are less expensive to produce and use less material, making them a budget-friendly option for certain projects.
Application:
Suitable for projects in soft soil or shallow drilling, such as sandy or clay soils, where the geological conditions are relatively straightforward.
