The 20th China Coal Mining Expo 2023 was grandly held at the China International Exhibition Center in Beijing. This industry event has been deeply involved in the coal field for 40 years and provides a unique platform for Chinese foreign coal mining and mining equipment companies to find business opportunities, open up markets, enhance brands, strengthen exchanges, and explore industry development trends. With the theme of "Intelligence Leading the Future, Green Shared Development", this exhibition comprehensively demonstrated new equipment, new technologies and new products in the coal industry.

As a leading company in China's hydraulic hose industry, Litong Technology once again participated in the Beijing Coal Exhibition, becoming one of the highlights of the exhibition that attracted customers 'attention. Litong Technology actively responded to the theme of the exhibition, bringing products such as wear-resistant black technology's customized outer-coated ultra-wear-resistant mining hoses, upgraded Super Battery low-bend series hoses, and ultra-high pressure resin hoses. It fully demonstrated its latest achievements and breakthroughs in helping the coal industry achieve low-carbonization, intelligent and green development. This performance has won high praise from new and old customers and industry experts.

In order to ensure the safety of coal mining, Litong Technology has always adhered to the R & D and production philosophy of "safety first, quality first". It is reported that their differentiated innovation has accelerated the pace of transformation of old and new kinetic energy, comprehensively improved the research and development, design and manufacturing capabilities of mining pipeline integration solutions, and created safer and more efficient mining hydraulic hoses and assembly products. Since 2009, Litong Technology has obtained safety standard certification, marking that it has reached standards and stability in terms of quality and safety, and demonstrated its qualifications in promoting safe production in the coal industry.

Among them, the customized outer coating ultra-wear-resistant mining hose uses a polymer material outer coating. After 2000 reciprocating wear tests, there is no loss of quality and meets the GB/T12721-2007 standard. On the other hand, the Super Hercules Low Bend series of hoses stands out for their minimum bend radius, which is 34% lower than the ISO 18752 Class C standard, high pressure, and long life of 1 million pulses. This series of hoses is also equipped with Litong self-developed hose fittings and hydrogenated nitrile seals for excellent durability.

The ultra-high pressure resin hose has a maximum working pressure of 400MPa, a lower industry average bending radius and a safety factor of 2.5 times, and a maximum burst pressure of 1000MPa, ensuring the application of coal mine oil and water-based hydraulic oil under extreme high pressure conditions. Pressurless transportation of oil or water.

Against the background of carbon peaking and carbon neutrality, Litong Technology is committed to intelligent transformation and upgrading, especially carrying out technical research around the manufacturing of coal mine hydraulic supports, and continuously improving the safety, stability and reliability of products to meet the requirements of comprehensive coal mining units and other hydraulic systems under extreme high pressure and harsh conditions.
