Q345B方管在近几年在管道中的应用是很大的，可以说是有了巨大的应用。在管道应用中由于大量运输一些粘稠度比较高的液体，所以它独有的耐磨性就体现出来了，那么Q345B方管的耐磨性有什么特点呢?

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.很好的连接性能：

1. Good connection performance:

Q345B方管基材是普通Q235钢板,保证耐磨钢板具有韧性和塑性,提供抵抗外力的强度,可以采取焊接、塞焊、螺栓连接等多种方式和其他结构进行联系,连接牢固,不容易脱落,连接方式多于其他材料;

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.很好的选择性能：

2. Good selectivity:

Q345B方管选择不同厚度基材,堆焊不同层数和厚度的合金耐磨层,可以得到不同厚度和不同用途的钢板,最大厚度可达到30㎜以上;

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.很好的加工性能：

3. Good processing performance:

Q345B方管能够按要求加工成不同规格尺寸,可以进行加工、冷弯成型、焊接、弯曲等,方便使用;可以现场拼焊成型,使维修更换工作变得省时、方便,大大降低工作强度.

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.很好的性价格比：

4. Good sex-price ratio:

Q345B方管价格较普通材料有所提高,但考虑到产品使用寿命,综合考虑维修费用、备件费用和停机损失,其性能价格比远高于普通钢板和其他材料.

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.很高的耐磨性能：

5. High wear resistance:

Q345B方管耐磨层厚度3-12㎜,耐磨层硬度可以达到HRC58-62,耐磨性能是普通钢板的15-20倍以上,是低合金钢板性能5-10倍以上,是高铬铸铁耐磨性能2-5倍以上,耐磨性远远高于喷焊和热喷涂等方法.

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.较好的冲击性能：

6. Better impact performance:

Q345B方管是双层金属结构,耐磨层和基材之间是冶金结合,结合强度高,可在受冲击的过程中吸收能量,耐磨层不会脱落,可以应用到振动、冲击较强的工况条件下,这一点是铸造耐磨材料和陶瓷材料所不及的.

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.很好的耐温性能：

7. Good temperature resistance:

Q345B方管合金碳化物在高温下有很强的稳定性能,耐磨钢板可以在500℃内使用,其他特殊要求温度可以定制生产,能够满足1200℃以内条件下使用;陶瓷、聚氨脂、高分子材料等采取粘贴方式耐磨材料无法满足如此高温要求.

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.
