Wear resistance of seamless pipe

Views: 2     Author: Site Editor     Publish Time: 2020-07-20      Origin: Site

    Thick-walled seamless pipes have been widely used in pipelines in recent years. In pipeline applications, due to the transportation of a large number of relatively high-viscosity liquids, its wear resistance is reflected. What are the characteristics of the wear resistance of the seam pipe?

1. Wear resistance:

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

2. Impact performance:

    The thick-walled seamless pipe is a double-layer metal structure. The wear-resistant layer and the base material are metallurgically bonded. The bonding strength is high. It can absorb energy during the impact. The wear-resistant layer will not fall off. It can be applied to vibration and impact. Under strong working conditions, this is beyond the reach of cast wear-resistant materials and ceramic materials.

3. Temperature resistance performance:

    Thick-walled seamless pipe alloy carbides have strong stability at high temperatures, wear-resistant steel plates can be used within 500 ℃, other special requirements temperature can be customized production, can meet the conditions within 1200 ℃; ceramic, polyurethane , High-molecular materials and other wear-resistant materials with adhesive methods cannot meet such high temperature requirements.

4. Connection performance:

    The base material of the thick-walled seamless pipe is ordinary Q235 steel plate, which ensures the toughness and plasticity of the wear-resistant steel plate, and provides the strength to resist external forces. It can be connected with other structures by various methods such as welding, plug welding, and bolt connection, and the connection is firm. Easy to fall off, more connection methods than other materials.

5. Select performance:

    Thick-walled seamless pipe manufacturers choose substrates of different thicknesses, and surfacing alloy wear-resistant layers of different layers and thicknesses, and steel plates of different thicknesses and different purposes can be obtained, and the thickness can reach more than 30 mm;

6. Processing performance:

    Thick-walled seamless pipes can be processed into different specifications and sizes as required. They can be processed, cold-formed, welded, bent, etc., which are convenient to use; they can be tailor-welded on-site, which makes maintenance and replacement work time-saving and convenient, greatly reducing work strength.
