Cold drawn seamless tubing is a steel pipe with high dimensional accuracy and good surface finish for mechanical structure and hydraulic equipment. The use of cold drawn seamless tubing to manufacture mechanical structures or hydraulic equipment can greatly save machining hours, improve material utilization, and help improve product quality.
What are the five characteristics of cold drawn seamless tubing?
1) Compressive strength of cold drawn seamless tubing
Cold drawn seamless tubing have high tensile strength and compressive strength. The tensile strength of cold drawn seamless tubing is one of the important links in the compressive strength assignment of construction engineering design. High tensile strength can save the use of steel plates; Avoid malignant accidents with ductile damage.
2) Deformation capacity of cold drawn seamless tubing
The plastic deformation and ductility of cold drawn seamless tubing are good. Good plastic deformation can ensure that the structure can have significant deformation before destruction, so as to prevent the risk of ductile damage; cold drawn seamless tubing has sufficient plastic deformation, and the stress in the peak period of the structure will be redistributed, making the structure in-situ stress The spread tends to be gentle. Good ductility means that under the effect of dynamic and static loads, more kinetic energy must be digested and absorbed when the structure is destroyed, so as to reduce the risk level of ductile failure. For the structure of the plastic deformation design scheme and the structure of the earthquake disaster area, the size of the deformation working capacity of the cold drawn seamless tubing has a particularly critical practical significance.
3) Production and processing characteristics of cold drawn seamless tubing
It can be integrated into cold and heat treatment, and does not have a great harmful effect on compressive strength, plastic deformation and ductility due to this production process.
4) Performance of cold drawn seamless tubing
Refers to the service life of cold drawn seamless tubing. The key factor affecting the service life of the cold drawn seamless tubing is the corrosion resistance of the cold drawn seamless tubing; the second is the need to avoid the serious deterioration of the physical properties of the cold drawn seamless tubing under the effect of long-term load and constant load driving force. .
