Seamless pipe (SMLS) is a steel pipe made of a single piece of metal with no joints on the surface. It is made of a steel ingot or a solid tube blank through perforation to form a capillary tube, and then hot-rolled, cold-rolled or cold-drawn. The characteristics of seamless steel pipes are different from other steel pipes. They are strong in corrosion resistance, strong and durable, suitable for different purposes, and have strong applicability in the construction process. They are not restricted by natural conditions during the installation process. The details are as follows:
1. Excellent wear resistance
The thickness of the wear-resistant layer of the seamless pipe is 3-12mm, and the hardness of the wear-resistant layer can reach HRC58-62. The grinding performance is more than 2-5 times, and the wear resistance is much higher than that of spray welding and thermal spraying.
2. Excellent impact performance
The 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 process. The wear-resistant layer will not fall off and can be used in vibration and impact Under strong working conditions, this is beyond the reach of cast wear-resistant materials and ceramic materials.
3. Excellent temperature resistance
The seamless pipe alloy carbide has strong stability at high temperature, and the wear-resistant steel plate can be used within 500°C.The temperature of other special requirements can be customized and produced, which can meet the use under the condition of 1200°C; the wear-resistant materials such as ceramics, polyurethane, and molecular materials cannot meet such high temperature requirements by pasting.
4. Excellent connection performance
The base material of the seamless pipe is a general Q235 steel plate, which ensures that the wear-resistant steel plate has resistance and plasticity.
It provides strength against external force, and can be connected with other structures by welding, plug welding, bolt connection and other methods. The connection is firm and not easy to fall off. There are more connection methods than other materials.
5. Excellent processing performance
Seamless pipes can be processed into different standard sizes according to requirements, and can be processed, cold-formed, welded, bent, etc., which are convenient to use; they can be tailor-welded on site, making repair and replacement work time-saving and convenient, and greatly reducing work intensity.
6. High cost performance
The price of seamless pipe is slightly higher than that of general steel, but considering the service life of the product, as well as repair costs, spare parts costs, etc., its performance-price ratio is much higher than that of general steel plates and other steel products.
