Seamless OCTG casing
Seamless casing is a casing made of seamless steel pipe as raw material. Seamless pipe is a pipe product used to transport fluid or gas. It is characterized by no welds, so it is also called seamless steel pipe. Compared with welded steel pipes, seamless pipes have higher strength and pressure resistance, and are suitable for withstanding harsh conditions such as high pressure, high temperature, and corrosive media.阅读更多 -
Black welded steel tube

Steel sheet pile static pressure construction
Before construction, sufficient preparation work needs to be carried out. First, the construction site needs to be cleared to ensure it is flat and free of obstacles. Secondly, you need to check whether the static pressure equipment is normal and prepare all the required materials. Finally, technical training and safety education need to be provided to construction personnel to ensure that they understand the construction process and safe operating procedures.阅读更多 -
Life expectancy of black steel pipe
Black steel pipe is primarily composed of carbon and iron, with trace amounts of other elements such as manganese, sulfur, and phosphorus. Unlike galvanized steel pipe, which is coated with zinc for corrosion resistance, black steel pipe relies on its natural oxide layer for protection.阅读更多 -
Steel sheet pile driver
Steel sheet piles are a common pile type in the field of steel structures and have the advantages of high bearing capacity, short construction period, and high construction efficiency. In the construction of steel sheet piles, the role of the pile driver is to drill the top of the steel sheet pile into the ground, and gradually let the steel sheet pile sink into the ground under conditions such as controlling the strength and frequency of the pile driver.阅读更多 -
