Q345B square pipe has been widely used in pipelines in recent years. It can be said that Q345B square pipe has great application. In the pipeline application, because a large number of high viscosity liquids are transported, the unique wear resistance of Q345B square pipe is reflected. What are the characteristics of wear resistance of Q345B square pipe?
1. Good connection performance:
Q345B square pipe base material is ordinary Q235 steel plate, which guarantees the toughness and plasticity of wear-resistant steel plate and provides strength against external forces. It can be connected with other structures by welding, plug welding, bolt connection, etc. The connection is firm, not easy to fall off, and the connection mode is more than other materials.
2. Good selectivity:
Q345B square pipe can be welded with different thickness of base material and different layers and thicknesses of alloy wear-resistant layer, and steel plates with different thickness and different uses can be obtained. The maximum thickness can reach more than 30 feet.
3. Good processing performance:
Q345B square pipe can be processed into different specifications and sizes according to requirements. It can be processed, cold-formed, welded, bended, etc. It is convenient to use. It can be tailor-welded on site, which makes maintenance and replacement work time-saving, convenient and greatly reduces the working strength.
4. Good sex-price ratio:
The price of Q345B square tube is higher than that of common material, but considering the service life of the product, considering the maintenance cost, spare parts cost and downtime loss, the performance-price ratio of Q345B square tube is much higher than that of common steel plate and other materials.
5. High wear resistance:
The wear resistance of Q345B square pipe is 5-10 times of that of low alloy steel plate, 2-5 times of that of high chromium cast iron, and much higher than that of spray welding and thermal spraying.
6. Better impact performance:
Q345B square pipe is a double-layer metal structure, the wear-resistant layer and the base material are metallurgical bonding, the bonding strength is high, it can absorb energy in the process of being impacted, the wear-resistant layer will not fall off, it can be applied to the working conditions of strong vibration and impact, which is inferior to cast wear-resistant material and ceramic material.
7. Good temperature resistance:
Q345B square tube alloy carbide has strong stability at high temperature, wear-resistant steel plate can be used at 500 C, other special requirements temperature can be customized production, can meet the conditions of 1200 C. Ceramics, polyurethane, macromolecule materials and other wear-resistant materials can not meet such high temperature requirements by sticking.
