What are the mechanical performance advantages of seamless steel tubes？

The mechanical properties of seamless steel tubes are very stable, so they can be widely used. General seamless pipes must be tested for mechanical properties before they leave the field. Not qualified. On the whole, we should be able to basically see that the tensile strength of seamless pipes is not only high, but also the yield point.

1. High abrasion resistance: The thickness of the abrasion resistance layer of thick-walled seamless steel pipe is 3-12mm, and the hardness of the abrasion resistance layer can reach HRC58-62. The performance is more than 5-10 times, which is more than 2-5 times the wear resistance of high chromium cast iron. The wear resistance is much higher than spray welding and thermal spraying.

2. Good impact performance: The thick-walled seamless steel pipe is a double-layer metal structure, and the wear-resistant layer and the substrate are metallurgically bonded, with high bonding strength, which can absorb energy during the impact process, and the wear-resistant layer will not Shedding can be applied to the working conditions with strong vibration and impact, which is beyond the capability of casting wear-resistant materials and ceramic materials.

3. Good temperature resistance: Thick-walled seamless steel tube alloy carbides have strong stability at high temperatures. Wear-resistant steel plates can be used at 500°C. Other special requirements can be customized and can meet the temperature within 1200°C. Use under conditions; ceramics, polyurethane, polymer materials and other wear-resistant materials can not meet such high temperature requirements.

4. Good connection performance: The base material of thick-walled seamless steel pipe is ordinary Q235 steel plate, which guarantees the toughness and plasticity of the wear-resistant steel plate, and provides strength against external forces. We can adopt welding, plug welding, bolt connection and other methods and other The structure is connected, the connection is firm, it is not easy to fall off, and the connection method is more than other materials;

5. Good selection performance: thick-walled seamless steel pipes are selected from different thickness substrates, and alloy wear-resistant layers of different layers and thicknesses are deposited, and steel plates of different thicknesses and different uses can be obtained, and the maximum thickness can reach more than 30mm.

6. Good processing performance: thick-walled seamless steel pipes can be processed into different specifications and sizes according to requirements, which can be processed, cold-formed, welded, bent, etc., and easy to use; can be welded on-site to make maintenance and replacement work become Save time and convenience, greatly reduce work intensity.

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