Q345B方管在近幾年在管道中的應用是很大的，可以說是有了巨大的應用。在管道應用中由于大量運輸一些粘稠度比較高的液體，所以它獨有的耐磨性就體現出來了，那么Q345B方管的耐磨性有什么特點呢?

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.很好的連接性能：

1. Good connection performance:

Q345B方管基材是普通Q235鋼板,保證耐磨鋼板具有韌性和塑性,提供抵抗外力的強度,可以采取焊接、塞焊、螺栓連接等多種方式和其他結構進行聯系,連接牢固,不容易脫落,連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.很好的選擇性能：

2. Good selectivity:

Q345B方管選擇不同厚度基材,堆焊不同層數和厚度的合金耐磨層,可以得到不同厚度和不同用途的鋼板,最大厚度可達到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方管能夠按要求加工成不同規格尺寸,可以進行加工、冷彎成型、焊接、彎曲等,方便使用;可以現場拼焊成型,使維修更換工作變得省時、方便,大大降低工作強度.

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.很好的性價格比：

4. Good sex-price ratio:

Q345B方管價格較普通材料有所提高,但考慮到產品使用壽命,綜合考慮維修費用、備件費用和停機損失,其性能價格比遠高于普通鋼板和其他材料.

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方管耐磨層厚度3-12㎜,耐磨層硬度可以達到HRC58-62,耐磨性能是普通鋼板的15-20倍以上,是低合金鋼板性能5-10倍以上,是高鉻鑄鐵耐磨性能2-5倍以上,耐磨性遠遠高于噴焊和熱噴涂等方法.

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.較好的沖擊性能：

6. Better impact performance:

Q345B方管是雙層金屬結構,耐磨層和基材之間是冶金結合,結合強度高,可在受沖擊的過程中吸收能量,耐磨層不會脫落,可以應用到振動、沖擊較強的工況條件下,這一點是鑄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.很好的耐溫性能：

7. Good temperature resistance:

Q345B方管合金碳化物在高溫下有很強的穩定性能,耐磨鋼板可以在500℃內使用,其他特殊要求溫度可以定制生產,能夠滿足1200℃以內條件下使用;陶瓷、聚氨脂、高分子材料等采取粘貼方式耐磨材料無法滿足如此高溫要求.

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.
