Hydraulic steel pipes are basically divided into fluid pipes and oil steel tubes used in hydraulic systems, also known as honing pipes, and cold drawn or cold rolled seamless steel pipes also include hydraulic steel pipes.
Hydraulic steel pipe is a high-precision seamless steel pipe that uses seamless pipes to manufacture mechanical structures or hydraulic equipment, etc., and the precision steel pipes are cold-drawn or cold-rolled. Because the inner and outer walls of precision steel pipes have no oxide layer, withstand high pressure without leakage, high precision, high finish, no deformation in cold bending, flaring, flattening without cracks, etc., they are mainly used to produce pneumatic or hydraulic products.
Causes of hydraulic steel pipe leakage
1. The pipeline installation does not meet the requirements
(1) Poor pipe bending
(2) The installation and fixation of the pipeline does not meet the requirements
①When installing the oil pipe, it is forced to assemble regardless of the length, angle and thread of the pipe, which will deform the pipe and generate installation stress. At the same time, it is easy to damage the pipe, resulting in a decrease in its strength;
② When installing the oil pipe, do not pay attention to fixing it. When the bolt is tightened, the pipe will rotate together, causing the pipe to twist or collide with other parts to cause friction and shorten the service life of the pipe;
③ Sometimes the clamps of the pipeline are fixed too loosely, which increases the friction and vibration between the pipeline and the clamps; sometimes it is too tight, causing the surface of the pipeline (especially the aluminum tube) to be pinched and deformed; these situations will damage the pipeline and cause oil leakage ;
④The tightening torque of the pipeline joints seriously exceeds the regulations, causing the bell mouth of the joints to break, the threads to be strained and tripped, resulting in serious oil leakage accidents.
2. Fatigue damage or aging of hydraulic pipelines
3. Hydraulic oil pollution and pipeline surface pollution
Precaution
1. Carefully check the quality of the pipeline, and strictly prohibit the use of unqualified pipelines
2. Correctly install the pipeline, and illegal assembly is strictly prohibited
3. Proper use and maintenance, no pollution of the hydraulic system
