Introduction of mud pump cylinder liner manufacturers Since 1997, HNA has been famous for its professional engineering design and production technology, as well as excellent product quality in the oil and gas field. It adopts exquisite precision casting, heat treatment technology and finishing technology. The HNA casting products designed and produced are not only used in the production and manufacture of mud pumps, plunger pumps, fracturing pumps and accessories, but also widely used in automobiles, high-speed rail and rail transit, heavy trucks and special vehicles, mining machinery, Production and manufacture of products and components in the fields of machinery, infrastructure equipment, and other heavy machinery and equipment, and can be designed and customized according to the special requirements of customers.
* HNA is one of the key enterprises of China Special Steel Association and Foundry Association. It has been cooperating with universities and research institutes for many years. It is a doctoral research unit of China Iron and Steel Industry Association and a development base for first-class universities. The company has more than 70 scientific research personnel with intermediate and senior titles, and a strong technical team dedicated to integrated research and development, design, production, sales and service.
* HNA has independent mold development and design capabilities, as well as formulation technology capabilities for various high-performance casting alloy materials. For example, the inner liner of HNA cylinder liner is made of Cr iron and pig iron with high wear resistance through centrifugal casting process (currently this formula is only used by Qingdao TSC and HNA companies, this casting method and inner liner composition formula are 98 years old. HNA has jointly developed with American customers and continues to this day), which greatly improves the wear resistance, high temperature resistance, low temperature resistance and high corrosion performance of drilling fluid, and greatly improves the service life under various working conditions. At the same time, HNA has also developed a high-performance composite alloy bimetallic cylinder liner. Using the self-developed inner sleeve casting alloy material and casting process, the service life of the composite alloy bimetallic cylinder liner has been increased to more than 2,000 hours.
* HNA has an annual output of 150,000 tons of high-quality castings and 100,000 tons of forgings. Our main production equipment is: three 32-ton electric arc furnaces, 32-ton ladle refining furnace LF, and one vacuum degassing furnace VD, one 15 Tons of vacuum oxygen blowing decarburization converter VODC, dozens of sets of sand mold and silica sol precision casting equipment.
* HNA casting products mainly include various sizes of castings and mechanical parts, which are widely used in industries such as petroleum equipment, wind power, chemical industry, machinery, automobiles, ships, power plants, metallurgy, mining, petrochemical and other industries.
