About Us

Henan zhongyuan Heavy Forging Co.,Ltd(HHF) founded in 2006, the company has accumulated nearly 20 years of deep professional experience and technological expertise in the field of heavy-duty forging.

The‍‌‍‍‌ factory is about 150 mu large, equivalent to 100,000 square meters. At the company's production base, there are 3 sets of the factory-style drop forging lines on a large scale (with the basic equipment being a 10,000 ton hydraulic press), 2 advanced mold forging production lines and some big CNC machining centers, heat treating lines, the laboratory of second class national system is quite well equipped too.

About 500 employees are engaged by the company at the moment out of which more than 50 are dedicated researchers who, with their high-level engineers and technical specialists are engaged in the development of new materials, methods and technologies.

In addition to being certified with the basic American API Q1 standard and licensing with the American standards on API 7-1 for both drill collars and stabilizers, the company also possesses an approval by the Chinese CSSC system as for as international certificates the company is certified with ISO 9001:2008 and ISO/TS 29001.

With‍‌‍‍‌ 20 years of experience and expertise, we're constantly enhancing our manufacturing capabilities to respond to various customer needs in terms of dimensions, materials, or performance requirements.

Our close collaboration between the engineering and production teams enables us to produce parts that accurately match your requirements. Our solutions will be delivered right on the first try as they seamlessly match your operational goals.

We do our best to offer you competitive prices while ensuring the highest quality by process optimization, supply chain efficiency, and cost-effective production. To give you the most secure feeling, we back every our product with two-year warranty highlighting our trust towards customer satisfaction through products that will serve for a long time with no breakdowns.

The heart of our quality system is a Level 2 in-house laboratory, where sophisticated testing procedures, e.g., chemical analysis, mechanical property determination, and hardness verification, can be done at different stages of production. Such comprehensive quality assurance through the production cycle not only maintains production quality but also ensures full compliance with international standards as well as the customer's particular requirements at every level of the production cycle.

We at HHF are the proud pioneers of a major innovation in China's drilling industry by designing, producing, and commercializing a 6-rib under-reaming drill stabilizer. This novel product is essentially the motor of today's highly productive drillings and has opened the doors to a new level of downhole drilling capabilities by combining precise engineering with reliable, well-designed tools at a very low cost, which, in return, brings up great operational returns. The tool is a must-have for operations that have difficult geological features.

One of the elements of our pledge for excellence at HHF is sourcing 100 per cent of the raw materials for the products exclusively from China's most famous and trustworthy steel mills. This enables us to maintain the material quality standards and achieve metallurgical characteristics that are outstanding from the very beginning. To achieve the manufacturing of a drill stabilizer HHF combines highly advanced forging techniques with the finest heat treatment technologies and precision CNC finishing. Each phase of the process is closely monitored in HHF to create drill stabilizers under-reaming that, apart from meeting the standards, are of a quality that can outclass those of the entire domestic industry in the drilling equipment area, with the result that HHF is looked up to by competitors for its products quality.

Until now, HHF's innovative 6-rib under-reaming drill stabilizers have enjoyed worldwide acceptance, our products reaching various international drilling markets like South Africa, Australia, the Untied States, Canada, Brazil, Peru, and India. HHF performance at a reliable level for a long duration time enabled it to forge durable relationships with many global drilling machinery manufacturers and internationally recognized drilling companies. Our company relationships with these enterprises are built upon mutual trust, technical exchanges, and a joint effort towards the further development of drilling technology globally.

National Level II laboratory

HHF Quality System includes a National Level II Physical & Chemical Laboratory to provide customers and industry quality organizations with high-quality inspection evidence.

Complying with the requirements for the physical and chemical laboratories of National Grade 2 standards, the lab is able to perform the following tests: tensile test, minus 80 degrees Celsius temperature impact test, chemical composition analysis, metallography testing, non-metallic inclusions analysis, gas content testing, grain size and crystallographic orientation analysis, as well as magnetic induction strength test, non-magnet magnetic induction gradient, and intergranular corrosion test.

Logistics & Delivery Flexibility

We deliver logistics solutions that suit your unique supply chain requirements, covering the entire logistics process with a high level of adaptability, efficiency, and transparency.

Delivery Methods:

1.  Port Delivery: We are able to ship goods to ports all over China, such as Shanghai, Ningbo, Tianjin, Qingdao, and Guangzhou, to name a few but not limit here. The goods will be packed and made ready for transport in the port per the selected Incoterm.
