Engineered to operate in the most demanding geological formations. Explore our flagship models designed for CFA, horizontal directional, and water well operations.
In geotechnical engineering, mining exploration, and infrastructure piling, the retrieval of undisturbed geological samples is critical. The HQ core barrel, built to DCDMA (Diamond Core Drill Manufacturers Association) wireline specifications, represents the standard for medium-to-hard rock diamond coring. Featuring a nominal hole diameter of 96 mm (3.78 in) and a core diameter of 63.5 mm (2.5 in), this double-tube system is engineered to protect core samples from washing action by directing drilling fluid between the inner and outer tubes.
Choosing an industrial-grade HQ core barrel requires understanding metallurgical compositions, precision tolerance threading, and hydraulic flow balance. For global procurement officers and exploration teams, selecting the right exporter is not just a commercial choice but a decision that directly affects core recovery rates (CRR) and rock quality designations (RQD).
Founded in the early 1990s, the core team of SINOVO Group began its journey in construction machinery. Over three decades, the company has developed strategic alliances with leading international manufacturers. Today, SINOVO is a key exporter of drilling equipment, serving clients in over 120 countries and regions.
To support expansion in Southeast Asia, SINOVO established TEG FAR EAST company in Singapore in 2008. In 2010, the group invested 120 million yuan to construct a 67-mu production base in the Hebei Xianghe Demonstration Zone. Located 100 kilometers from Tianjin Port, this manufacturing facility is optimized for lower shipping costs and efficient export logistics.
Beijing Sinovo International & Sinovo Heavy Industry Co. Ltd. are ISO9001:2015 certified manufacturers. The company's production facilities cover 7,800 square meters and house over 50 heavy industrial production units. Current annual production capacities include:
| Equipment Category | Annual Manufacturing Output | Primary Industrial Applications |

Watch our rotary drilling rigs and core exploration systems in action. SINOVO's engineering and manufacturing capabilities deliver reliable geotechnical equipment worldwide.
In global mineral exploration and civil engineering, Chinese manufacturers have moved from offering low-cost options to providing high-quality technology. Partnering with a professional supplier like SINOVO offers several key advantages:
Our HQ core barrels and engineering rigs are deployed in complex geological environments around the globe.
Retrieve geological cores in gold, copper, and base metal deposits. The double-tube design protects fragile core samples from pressurized drilling fluids, ensuring high-quality stratigraphic assessment.
For high-rise buildings and bridges, our systems sample bedrock to determine load-bearing capacity before drilling large-diameter pile holes.
Enables systematic core extraction in river valleys and steep canyon walls, helping engineers evaluate seepage pathways and rock fractures.
SINOVO products conform to international quality and engineering standards, validated by global inspection agencies.

Optimized for soil reinforcement in subway, highway, and dam foundation projects. Equipped with an onboard 3-ton crane arm for material handling and reduced manual labor.
Answers to technical and logistical questions commonly raised by procurement managers and field operations engineers.
High-grade outer and inner tubes are typically manufactured from 4130 alloy steel or Chinese 30CrMo equivalent. These materials undergo cold-drawing and thermal tempering to resist twist, bending, and abrasive wear under high hydraulic pressure.
By enclosing the core sample inside a stationary inner tube, the outer tube rotates independently. Drilling fluid is directed between the two tubes, preventing the high-velocity mud flow from eroding or washing away the core sample.
For standard models, the typical dispatch lead time is 10 to 15 days. For complex customized rig configurations or major tool shipments, lead times are determined by manufacturing schedules and are tracked step-by-step.
Yes. All engineering rigs and drilling tools can be inspected by recognized third-party agencies (such as SGS, BV, or Intertek) prior to port clearance to verify structural and mechanical compliance.
