Quality is the cornerstone of Heng Long’s development. We adhere to international advanced quality management standards throughout the entire process of R&D, production, and after-sales service, and have obtained a number of authoritative quality certifications and technical patents, which fully demonstrate the reliability of our rock drilling tools and mechanical components.
1. International Quality Management System Certification
- ISO 9001:2015 Quality Management System Certification
We have strictly implemented the ISO 9001:2015 standard and established a complete quality management system covering raw material procurement, production process control, finished product inspection, and customer service. The certification ensures that every batch of products is manufactured in accordance with standardized procedures, and the product quality is stable and traceable.
- CE Certification
Our core products (including drill bits, drill rods, and shank adapters) have passed the CE certification, which means they fully comply with the safety, health, and environmental protection standards of the European Economic Area (EEA). This certification is a key "passport" for our products to enter the European market and win the trust of global customers.
2. Industry-Specific Quality & Safety Certifications
- API Certification (American Petroleum Institute)
For products applied in oil and gas drilling projects, we have obtained the API certification. This certification is recognized globally in the petroleum and natural gas industry, representing that our products meet the strict technical requirements for high-pressure, high-temperature, and harsh working conditions.
- Mine Safety Product Certification
Aiming at the mining industry’s demand for equipment safety, our rock drilling tools for mine use have passed the national mine safety product certification. The products have passed rigorous tests on wear resistance, impact resistance, and structural stability, ensuring safe and reliable operation in underground mining, open-pit mining, and other high-risk scenarios.
