Technology R & D

After nearly 5 years of research and development, Henan Earl Hydraulics Technology Development Co., Ltd. has independently developed and produced characteristic high temperature resistant pipes, low temperature resistant pipes, oil resistant pipes, improved winding pipes, and low pressure oil pipeline winding production technology and has applied for national invention patents. It broke the monopoly of Japanese, European, American and other countries' enterprises in the high-temperature and low-pressure oil pipeline winding technology used in the hydraulic system of construction machinery.
