Necessity of Corrosion Prevention for Seamless Steel Pipes of Shanghai Zhongze Yi Metal Materials Co., Ltd

The transportation of seamless steel pipes involves continuous high-temperature vapors, and the key to conducting thermal insulation for seamless steel pipes is to prevent gas heat loss. To ensure that during the transportation of hot steam, it is necessary to prevent the release of heat into the room, increase the indoor temperature, and prevent staff from touching the air duct and causing burns and bubbles.

In summer, condensation water is often generated on the surface due to the transportation vapor temperature being lower than the moisture content of the surrounding environment. Adding cooling loss to the air ducts of the centralized air conditioning system can cause environmental pollution to the decoration ceiling, walls, and floors due to the condensation of water droplets. Therefore, it is necessary to carry out cold insulation and thermal insulation in this area to solve the problem.

In many years of pipeline use, the wear resistance of seamless steel pipes has been continuously increased due to the transportation of highly viscous liquids. What are the characteristics of its wear resistance?

When coating the surface of seamless pipes, the coating thickness is 3mm to 12mm, and the coating strength can reach HRC58-HRC62. The wear resistance is about 15-20 times that of ordinary steel plates, 5-10 times that of low alloy steel plates, and 2-5 times that of high chromium cast iron. The wear resistance is much higher than that of spray welding and arc spraying.

Aluminum alloy carbides have extremely strong reliability at high temperatures, and seamless steel pipes can also achieve a normal usage experience under 500 ℃ temperature conditions. For other special requirements, the ambient temperature can be professionally customized to meet standard applications 

within 1200 ℃. Porcelain, polyurethane, fiber materials, etc. use adhesive methods, and metal composite materials cannot meet the requirements for continuous high temperatures.
