In May, 2016, the commendation meeting of 2015 Top 100 Enterprises in Luohe Development Zone was held in the Investment Service Center of the Development Zone. Luohe Lange Hydraulic won the honorary title of Top 100 Enterprises in Henan Development Zone (ranked 67th). In 2015, in the face of unfavorable factors such as continuous downward pressure and limited development factors of enterprises, Luohe Lange Hydraulic has withstood a severe test. All employees carry forward the enterprise spirit of loving their posts and being dedicated to their work, objectively analyze the current situation, and actively explore countermeasures, which have achieved remarkable results under the increasing pressure and contributed to the regional economy. At the same time, Luohe Lange Hydraulic also won the social responsibility of the Development Zone.

Key words: high pressure hose assembly, steel wire reinforced hose, hydraulic hose structure, high temperature resistant hose, hydraulic system connector.

According to the reinforced layer technology, high-pressure hose can be divided into two technical schools: High pressure steel wire braided tubing Technological characteristics: the steel wire is woven in a cross-mesh, and the layers are closely attached. Pressure range: 10-40MPa (suitable for medium and low pressure systems) Typical scenes: hydraulic lifting of agricultural machinery, lubrication pipeline of machine tools. High-pressure steel wire wound tubing (the focus of this paper) Process characteristics: The steel wire is wound in multiple layers with a spiral angle of 54, and the pulse resistance is improved by 50%. Pressure range: 35-120MPa (covering medium pressure to ultra-high pressure requirements) Typical scenarios: mine hydraulic support and oilfield fracturing equipment.
