What Are The Aspects Of The Wear Resistance Of Seamless Steel Tubes

Date:2018-12-21    keywords:seamless steel pipe
The application of thick-walled seamless steel pipes in pipelines in recent years is very large, and it can be said that there are huge applications. In pipeline applications, because of the large amount of liquids with relatively high viscosity, the unique wear resistance is reflected. What are the characteristics of the wear resistance of thick-walled seamless steel pipes? Let's talk about it today. Let me talk about this issue.

1. High wear resistance:
The thickness of the wear-resistant layer of thick-walled seamless steel pipe is 3-12mm, the hardness of wear-resistant layer can reach HRC58-62, the wear resistance is 15-20 times higher than that of ordinary steel plate, and the performance of low-alloy steel plate is 5-10 times higher than that. The wear resistance of chrome cast iron is 2-5 times higher, and the wear resistance is much higher than that of spray welding and thermal spraying.

2. Better impact performance:
Double-layer metal structure, metallurgical bonding between wear-resistant layer and substrate, high bonding strength, energy absorption in the process of impact, wear-resistant layer will not fall off, can be applied to working conditions with strong vibration and impact This point is not as good as casting wear resistant materials and ceramic materials.

3. Very good temperature resistance:
Its 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 under 1200 °C; ceramics, polyurethane, polymer Materials such as adhesive materials can not meet such high temperature requirements.

4. Very good connection performance:
Its base material is ordinary Q235 steel plate, which ensures that the wear-resistant steel plate has toughness and plasticity, and provides strength against external force. It can be connected with other structures by welding, plug welding, bolting, etc., and the connection is firm and not easy to fall off. More connections than other materials;

5. Good choice of performance:
Selecting different thickness substrates, surfacing different alloy layers and thickness of wear-resistant layer, can obtain steel plates of different thickness and different use, the maximum thickness can reach more than 30mm;

6. Very good processing performance:
It can be processed into different specifications according to requirements, can be processed, cold-formed, welded, bent, etc., easy to use; can be welded on the spot, making maintenance and replacement work time-saving, convenient, greatly reducing the work intensity.

7. Very good sex price ratio:
The price of thick-walled seamless steel pipe is higher than that of ordinary materials, but considering the service life of the product, considering the maintenance cost, spare parts cost and downtime loss, the performance price ratio is much higher than ordinary steel plates and other materials.
