Seamless pipe (SMLS) is a steel pipe made from a single piece of metal with no surface joints. It is made of steel ingot or blank solid tube 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 resistance
The thickness of the wear-resistant layer of the seamless pipe is 3-12 mm, 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
Seamless pipe is a double-layer metal structure. The wear-resistant layer and the base material are metallurgically bonded. The bond 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 strong working conditions, this is out of the reach of wear-resistant cast materials and ceramic materials.
3. Excellent temperature resistance Seamless pipe alloy carbide has strong temperature stability
high temperature, and wear-resistant steel plate can be used within 500 degree C. The temperature of other special requirements can be customized and produced, which can meet the use under the condition of 1200 degree C; Wear-resistant materials such as ceramics, polyurethane and molecular materials cannot meet such high temperature requirements when gluing.
4. Excellent performance
connection The base material of the seamless pipe is Q235 general steel plate, which ensures that the wear-resistant steel plate has strength and plasticity.
It provides resistance against external force and can be connected to other structures by welding, plug welding, bolt connection and other methods. The connection is firm and it is not easy to fall off. There are more connection methods than other materials.
5. Excellent performance
processing 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 custom welded on site, making repair and replacement work time-saving and convenient, and greatly reducing labor intensity.
6. High cost performance
The price of seamless pipe is slightly higher than that of general steel, but taking into account the service life of the product, as well as repair costs, spare parts costs, etc., its performance-price ratio is much higher. higher than that of general steel plates and other steel products.
