I. Introduction of Precision Hydraulic Seamless Steel Tube? Precision hydraulic seamless steel tube is made of high quality carbon structural steel or low alloy structural steel with high strength, high corrosion resistance and good low temperature performance. It can be cold-drawn or hot-rolled to obtain precise dimensions and smooth surfaces, while undergoing reasonable heat treatment and non-destructive testing, which makes the tubes have excellent mechanical properties and reliability.?
Precision Hydraulic Seamless Steel Tubes in the manufacturing process, need to carry out a number of procedures and quality inspection links to ensure the accuracy and quality of the tubes. Among them, the preparation stage requires the selection of suitable raw materials and the processes of melting, continuous casting and rolling to form steel plates of certain specifications. In the rolling process, parameters such as rolling speed, pass pressure and temperature need to be controlled to ensure the shape and dimensional accuracy of the pipe. Meanwhile, heat treatment and non-destructive testing are needed to ensure the mechanical properties and reliability of the tubes.
Two, precision seamless steel tube how to ensure high sealing? The high sealing of precision hydraulic seamless steel tube is one of its most important features, which can ensure the stability and reliability of the hydraulic system. The following are several aspects of precision seamless steel tube to ensure high sealing:
1. Material selection: precision hydraulic seamless steel tube selection of high-quality carbon structural steel or low alloy structural steel, these materials have excellent mechanical properties and corrosion resistance, which can ensure the sealing performance in the process of long-term use.
2. Manufacturing process: The manufacturing process of precision hydraulic seamless steel tubes adopts cold-drawn or hot-rolled treatment, which can obtain accurate dimensions and smooth surface. In addition, after reasonable heat treatment and non-destructive testing, the mechanical properties and sealing properties of the tubes can be further improved.
3. Processing accuracy: The processing accuracy of precision hydraulic seamless steel tubes is very high, which can ensure the accuracy of the inner and outer diameters of the tubes, wall thickness, coaxiality, and other parameters, thus avoiding the problem of poor sealing caused by dimensional errors.
4. Surface quality: the surface quality of precision hydraulic seamless steel pipe is very smooth, without obvious scratches, dents, oxidized skin and other defects, which can reduce fluid resistance and improve sealing performance.
5. Heat treatment quality: precision hydraulic seamless steel tube after reasonable heat treatment, can eliminate residual stress, improve the mechanical properties of the material and corrosion resistance, so as to ensure that the sealing performance in the long-term use of the process.
6. Non-destructive testing: Precision hydraulic seamless steel tubes need to be non-destructively tested during the manufacturing process, such as ray testing, ultrasonic testing, etc., to ensure that there are no defects and cracks inside the tubes, so that the sealing performance can be guaranteed in the long-term use process.
Precision hydraulic seamless steel tubes have strict requirements in material selection, manufacturing process, processing accuracy, surface quality, heat treatment quality and non-destructive testing, etc. These measures can ensure that the tubes are characterized by high sealing, high strength and long service life, so as to meet the needs of various fields.
