Special breakthrough for construction machinery hoses

A kind of high-temperature and low-pressure oil hose widely used in construction machinery was successfully developed at the engineering machinery hose plant in Luzhou City, Hebei Province. The product filled a gap in the domestic rubber hose industry and passed the scientific and technological achievements appraisal.
As a company engaged in scientific research and production of construction machinery hoses for many years, the plant has faced many difficulties in controlling the quality of mechanical products, such as poor physical properties of construction machinery used in oil hoses, and has actively collaborated with the Tianjin Institute of Engineering Machinery to draft and formulate a national plan. Construction machinery industry, high temperature and low pressure oil hose JB/T8406-2001 industry standards, and aimed at similar foreign products for technical research, research and development of new high temperature and low pressure oil hose new varieties. The product has the characteristics of high tear strength and long service life. The product's high temperature performance reaches 120°C, which is more than 200% higher than similar products, and its tear strength reaches 6.37MPa, which is 6% higher than similar products. The successful development of new products has broad prospects for promotion and good social and economic benefits.
