Core Retrieval Tongs for Core Drilling, 4in Cores

Core Retrieval Tongs for Core Drilling, 4in Cores

Fast, easy-to-use patented Core Retrieval Tongs. Simplified operation, improved reliability. Great for removing cores from asphalt or concrete surfaces. Compatible with industry standard core drilling equipment. Insert blades into space from core drill bit, grasp core with tongs, lift. Secure handling during core extraction. Optimal productivity and safety during core retrieval. No damage to core from improper tools. Lab acceptance testing without re-drilling. Tongs are welded, painted steel with plastic handle grips. Reduces downtime and improves efficiency.

What is Core Drilling

Core drilling is used in many industries, mining, construction, geotechnical. Extracting core samples from the ground to analyze the composition and structure of the underlying rock or soil. The core retrieval system is a critical part of core drilling, consisting of several key components, inner tube assembly, outer tube, head assembly. Inner tube assembly captures the core sample, outer tube provides support and protection. Head assembly, locking couplings and adapter coupling, secures inner tube assembly and allows core sample to be retrieved. Core retrieval tools, like core retrieval tongs, are essential for safely and efficiently extracting the core sample from the drill bit, to preserve the sample and the operation.

Core Retrieval Tools and Equipment

Core retrieval tools and equipment is designed for maximum productivity and safety during core drilling. Core retrieval tongs for example, remove cores from asphalt or concrete surfaces with ease. Tongs have simply insert blades that fit into the space created by the core drill bit, operator can grasp the core with plastic grips. No need to re-drill for damaged samples, secure handling and preserve the core. Other key tools are wireline drill rods, core drill bits, reaming shells, centralize the inner tube and improve sample recovery. Di-Corp core retrieval tools work in all ground conditions, compatible with industry leading coring systems, so your operation runs smoothly and efficiently.

Inner Tube Considerations for Drilling

The inner tube is a key component of the core retrieval system and its design and construction is critical to successful drilling. The inner tube must withstand the stresses and strains of drilling, high pressures and temperatures and be resistant to wear and corrosion. Typically made from precision, cold-drawn mechanical tubing the inner tube may have limitations in hardness and wear resistance. Some inner tubes are made from hardened steel or other wear resistant materials. The inner tube must also be properly secured to the outer tube and head assembly to prevent stuck tubes and ensure core sample retrieval. Proper durability and assembly of the inner tube is critical to maintaining the core sample and the drilling process.

Drilling

Drilling requires careful planning and execution to ensure productivity. The drill string, wireline drill rods and core drill bit must be properly assembled and maintained to prevent accidents and ensure drilling. The drilling site must be prepared with measures in place to prevent injuries and environmental damage. During drilling operators must monitor parameters such as drill bit rotation speed, feed rate and fluid pressure to maintain optimal conditions and prevent equipment damage or surrounding rock or soil issues. Regular maintenance and inspection of the drilling equipment, core retrieval system and drill string is critical to prevent breakdowns and ensure safe and productive operation. Using proper core retrieval tools like core retrieval tongs will prevent re-drilling and secure handling of the core sample, reducing the risk of damaged samples and overall productivity.
