On June 25, 2015, Litong Hydraulic Qingdao Research Institute settled in Rubber Valley. On July 13, 2015, Litong Hydraulic Company swore the third zero defect day. On August 13, 2015, Litong Hydraulic Excavator was carefree "the first excavator service vehicle" On October 27, 2015, Litong Hydraulic officially launched the 2015 Asia International Power Transmission and Control Technology Exhibition. Litong Hydraulics has obtained a variety of technical certificates to ensure that it can meet the needs of customers. Litong has passed product certifications, including safety standards (MA), MSHA, American Petroleum Institute (API) API-16C and API-7K, American Bureau of Transportation ABS (oil drilling equipment and steel wire), labor fire certification, etc. It fully meets the needs of equipment production, oil drilling, iron and steel metallurgy, railway transportation, energy, chemistry and other fields. On July 10, 2020, 2012, the party building work report of Litong party branch. The Communist Party of China Luohe Litong Hydraulic Technology Branch was established in 2012. At present, there are 24 formal party members, 2 reserve party members, 5 development goals and 13 activists. We are committed to making unremitting efforts to build a standardized party branch as soon as possible under the leadership of the Municipal Party Committee, the Development Zone Party and Municipal Committee, the Development Zone Party Working Committee, and the Central Party Branch of the Employer. Oilfield development has a strong representation in China. The oil pipeline produced by Litong Company is API specification type 16D. This specification has proved flame retardancy and consistency in the 30-minute flame data test, and has obtained the Ukraine GOST oil verification and Lowe fire test. Made in Germany, SBR is produced under extreme conditions such as high risk, high pressure, high temperature, and is dedicated to development and production. </div><div>The present invention adopts food-grade UPE inner tube, which can be used under high concentration and/or high temperature conditions. It has good durability against the most demanding cleaning-in-place (CIP) methods and materials (such as commonly used chemical cleaning), and has been tested for a long time to fully meet the transport and absorption of solid materials. Even steam up to 130°C can clean for 30 minutes. In addition, the inner barrel material is guaranteed to be odor-free, and the inner wall of the hose is free of phthalates. What is a high-pressure wear-resistant structure? The wear-resistant tube is generally a steel wire wound wear-resistant rubber tube, and the reinforcement layer is a high-strength steel wire wound layer. After special treatment, the inner layer is mostly UPE, and the outer layer is polyamide or polyurethane, which has low fluid resistance, strong wear resistance, small volume expansion, chemical corrosion resistance, light weight and small outer diameter. It is usually used for materials environment such as transportation or transportation of chemical mixtures. Hose connectors are available in carbon steel or stainless steel, compression equipment and processes.
