Casing Pipe & Accessories: Precision-Engineered Solutions for Deep Foundation Excellence

Casing Pipes are indispensable in deep foundation, bored pile, drill shaft, and column construction projects, ensuring borehole stability and safeguarding operational safety under challenging ground conditions.

Double Wall Casing:

Superior Strength & Alignment for High-Performance Drilling

Engineered for universal applicability, Double Wall Casing is specifically designed to withstand and transmit the extreme rotational and vertical forces generated by KDK rotary drives and oscillators. Its dual-wall construction guarantees:

l Perfect drill string alignment, minimizing deviation and vibration

l Enhanced torque transmission, optimizing drilling efficiency

l Superior structural integrity, ideal for HPHT (high-pressure, high-temperature) environments

l Best suited for: Deep drilling, complex geological formations, and projects requiring maximum operational precision.

Single Wall Casing: Cost-Effective & Lightweight for Efficient Deep Foundations

A cornerstone of deep foundation engineering, Single Wall Casing offers a practical, budget-friendly solution without compromising safety. Its simplified design—featuring only an outer wall—reduces production costs and weight, making it ideal for:

Weight-sensitive applications (e.g., soft soils, large-diameter casings)

Projects with logistical constraints (easier handling, transportation, and installation)

Standard bored pile and drill shaft construction where extreme forces are not a primary concern

Key Advantages:

l Economical – Lower material and manufacturing costs vs. double wall alternatives

l Lightweight – Simplifies deployment and reduces labor/equipment requirements

l Reliable Protection – Maintains borehole stability and prevents soil collapse

Casing Drive Adapter: Seamless Torque Transfer for Operational Efficiency

The Casing Drive Adapter is a critical component that ensures smooth, efficient power transmission from the rotary drive to the casing string. Its precision-engineered design:

l Minimizes energy loss during torque transfer

l Reduces wear on casing connections

l Enhances operational safety by preventing misalignment

l Ideal for: High-torque drilling operations requiring consistent performance.

Casing Shoes: Durability & Versatility for Challenging Environments

Casing Shoes are engineered to excel in demanding soil conditions and specialized applications like secant pile wall construction. Key features include:

l Reinforced cutting rings with weld-on teeth or replaceable cutting inserts for extended service life

l Optimized penetration in abrasive or mixed-ground formations

l Modular design for quick tooth replacement, reducing downtime

Perfect for: Projects requiring reliable performance in hard, rocky, or unstable soils.
