Product innovation and differentiation: rubber hoses are mainly used in construction machinery, coal mining machinery, chemical industry, oil drilling, food industry and other industries. The demand for long-life and multi-functional rubber hoses is increasing, and product innovation and differentiation will become the development trend of the rubber hose industry in the future. Since January 2017, Litong has successfully developed the Super Hercules series of fluid hoses, ultra-durable cleaning hoses, drilling and oil pipelines, and PTFE/HNBR hose "KING HOSE" series, and achieved excellent results. We have gradually become the leader of the international advanced hydraulic hose manufacturer, constantly pursuing progress and innovation!
Pipeline conveying steam at 180 degrees Celsius generally uses rubber high-temperature and high-pressure steam hoses. The inner and outer layers of the hose are made of EPDM rubber, and the middle is braided with one or more layers of steel wire, which can withstand a maximum temperature of 200 degrees Celsius. In addition, its working pressure can also be increased according to the number of steel wire braided layers used in its reinforcement layer, and it can withstand a maximum working pressure of 20Mpa and a burst pressure of 170Mpa. On August 12, 2019, Litong Hydraulic Technology Co., Ltd. successfully obtained the 16D certificate issued by the American Bureau of Shipping. The 16D BOP well control hose is mainly used in the control system to remotely control the opening and closing of the blow pipe and the high pressure It is an indispensable part of the oil drilling platform to transport hydraulic oil. Petroleum engineering has extremely strict safety requirements, and every link and every component used in these projects is required to be kept in the best condition.
As a high-pressure wear-resistant pipe, the sandblasting pipe has certain standards in its structure and size, and the gap between each rubber layer must also meet the requirements of quality inspection. If the rubber layer in the sandblasting tube and the gap between the layers of the sandblasting tube quality inspection center do not meet the product regulations, the error of the tube wall thickness will be too large. If the wall thickness error exceeds the allowable value, it will affect the tightness and tensile strength of the hose assembly, and even the hose joint will be deflected. Concrete conveying hose is used for concrete conveying in construction machinery, such as concrete conveying hose, pump truck, mortar sprayer and other construction machinery, its super wear-resistant performance makes its service life several times longer than ordinary concrete conveying pipes . This product protects against acids in concrete. The pipe body is made of UPE and SBR & NR synthetic rubber. The UPE material of the ordinary pipe adopts the domestic average molecular weight, and the UPE material used for the pipe body is imported from Germany, and the molecular density is about 5 million higher than the molecular weight of the domestic UPE material. Therefore, it has great chemical stability and ultra-high wear resistance.
