Description

TECHNICAL FIELD

[0001] The utility model belongs to high pressure rubber pipe technical field relates to a heat -preserving compression -resistant high pressure steel wire winding rubber pipe. BACKGROUND

[0002] The development history of high pressure rubber pipe is the epitome of the continuous progress of industrial technology. Since its birth, high pressure rubber pipe has rapidly occupied a place in multiple key fields due to its excellent pressure resistance, oil resistance, wear resistance and other characteristics. From the stable support of mine hydraulic support to the deep exploration of oil field development, from the solid structure of engineering construction to the efficient operation of hoisting and transportation, high pressure rubber pipe is ubiquitous. In the hot environment of metallurgical forging and pressing, under the heavy load challenge of mine equipment, and even in the navigation of ships in the vast ocean, high pressure rubber pipe plays a crucial role in connection, transmission and conveying function. With the continuous innovation of hydraulic system technology, the performance of engineering machinery is improving, and mine equipment is developing towards higher efficiency and intelligence. The demand for high pressure rubber pipe in these fields has also increased. This not only requires high pressure rubber pipe to have higher pressure resistance and longer service life, but also puts forward more stringent standards for its materials, processes and performance. Under this background, high pressure rubber pipe technology continues to innovate, and new materials and new processes emerge in an endless stream, making high pressure rubber pipe more outstanding in performance and more adaptable. Today, high pressure rubber pipe has become an indispensable transmission element in various mechanized and automated hydraulic systems, providing strong support for the smooth progress of industrial production.

[0003] But in the process of using traditional high pressure rubber pipe, the high pressure rubber pipe will be impacted by high pressure and high speed medium, and its internal wall is easy to wear. The pressure bearing capacity of the worn rubber pipe will decrease, and may cause leakage and other problems. And the traditional high pressure rubber pipe has relatively poor temperature resistance, and cannot be applied to low temperature working environment. In extreme temperature environment, the heat preservation performance of the traditional high pressure rubber pipe may be further reduced, and the low temperature environment may make the material become brittle and hard, thereby affecting the heat preservation and compression resistance effect, so it is necessary to develop high pressure rubber pipe with heat preservation performance. On the other hand, in many industrial fields such as petroleum, chemical industry, metallurgy, etc., high pressure fluid needs to be transmitted. Traditional rubber pipe may not meet the super high pressure demand, so it is necessary to develop compression resistant rubber pipe that can withstand super high pressure. UTILITY MODEL CONTENTS
