Core barrels and excess sleeves are indispensable tools in geological exploration and oil drilling. The core barrel is a device used to obtain underground rock samples, while the excess sleeve is used to extract rock samples from the core barrel.
Our core barrel adopts advanced design and manufacturing technology to ensure efficient and accurate acquisition of rock samples. It is composed of a hollow steel pipe that can extract rock samples from the ground during the underground drilling process. Our core barrel has high strength and durability, and can be used under various geological conditions, including rocks, sandstones, and mudstones.
The super sleeve is a tool used to extract rock samples from the core barrel. It consists of a rotatable casing and a locking device, which can safely remove rock samples from the core barrel from the borehole. Our ultra large set has high reliability and easy operation, which can quickly and effectively extract rock samples, reducing exploration and drilling time and costs.
Our core barrels and excess sleeves are widely used in fields such as geological exploration, oil drilling, and mineral exploitation. They can provide accurate rock samples, help geologists and engineers understand underground geological conditions, assess resource potential and risks, and formulate corresponding mining and development strategies.
Our core barrels and excess sleeves not only have high quality and reliability, but also have a variety of specifications and sizes to choose from to meet the needs of different projects. Our products undergo strict quality control and testing to ensure excellent performance and reliability under various working conditions.
If you are looking for high-quality and reliable core barrels and excess sets, we will be your preferred partner. We are committed to providing customers with the best solutions and high-quality products to meet their needs and expectations.
