Q:How can the immersed pipe pile put steel cage into the steel pipe? Which expert to answer?: The pile reinforcement cage construction characteristics: in general application of the reinforcement cage can be used when not required manual assembling reinforcement cage, such as deep or large pile diameter should be used for solid and solid mechanism of reinforcement cage better (by reinforcing cage seam welder production) to meet Zhuang Jishi high technology requirements, enhance the stability of pile foundation.

Q:What is the lifespan of galvanized steel pipes?: The lifespan of galvanized steel pipes can vary depending on several factors such as the quality of the galvanizing process, the environment in which they are installed, and how well they are maintained. However, on average, galvanized steel pipes can last between 40 to 70 years before they may start to show signs of corrosion or degradation.

Q:How are steel pipes classified based on their schedule?: Steel pipes are classified based on their schedule, which refers to the thickness of the pipe wall. The schedule classification is denoted by a number, such as 10, 20, 40, 80, etc., with higher numbers indicating thicker walls.

Q:What are the different types of steel pipe supports for thermal expansion?: There are several different types of steel pipe supports that can be used for thermal expansion, including rigid supports, sliding supports, and spring supports. Rigid supports provide fixed support to the pipe and do not allow for any movement. Sliding supports allow the pipe to move horizontally as it expands or contracts, while still providing vertical support. Spring supports use springs to support the weight of the pipe and allow for vertical movement as well as thermal expansion.

Q:How are steel pipes protected against underground corrosion?: Steel pipes are protected against underground corrosion through various methods such as cathodic protection, coatings, and corrosion inhibitors. Cathodic protection involves the use of sacrificial anodes or impressed current systems that direct corrosion away from the steel pipes. Coatings like epoxy or polyethylene are applied to the pipes to create a physical barrier against moisture and corrosive elements in the soil. Additionally, corrosion inhibitors can be added to the fluid inside the pipes to prevent corrosion from occurring.

Q:How do steel pipes withstand pressure?: Steel pipes are able to withstand pressure due to their high strength and durability. The material properties of steel, including its tensile strength and resistance to deformation, allow it to withstand the internal forces caused by pressure without experiencing significant distortion or failure. Additionally, the seamless construction of steel pipes ensures that there are no weak points or joints that could compromise their ability to withstand pressure.

Q:Can steel pipes be used for underground geothermal systems?: Indeed, underground geothermal systems can utilize steel pipes. Given their robustness and longevity, steel pipes are frequently employed in geothermal systems. They can endure the elevated temperatures and pressures inherent in the extraction and distribution of geothermal energy. Moreover, steel pipes exhibit excellent resistance to corrosion, a crucial attribute when contending with the subterranean milieu and the diverse array of minerals and chemicals present in the soil. Furthermore, steel pipes possess versatility, enabling straightforward underground installation and connection, rendering them a fitting selection for geothermal systems.

Q:What is the difference between steel pipes and cast iron pipes?: The main difference between steel pipes and cast iron pipes lies in their composition and properties. Steel pipes are made from an alloy of iron and carbon, which gives them high strength and durability. They are also resistant to corrosion and can withstand high pressure and temperature conditions. On the other hand, cast iron pipes are made from molten iron, which provides them with excellent soundproofing capabilities and resistance to fire. However, cast iron pipes are more prone to corrosion and can be brittle, making them less suitable for high-pressure applications.

Q:Can steel pipes be used for heat exchangers?: Yes, steel pipes can be used for heat exchangers. Steel is a commonly used material for heat exchangers due to its high thermal conductivity and durability. It can efficiently transfer heat between two fluids, making it suitable for various industrial applications.

Q:Are steel pipes resistant to chemicals and corrosion?: Yes, steel pipes are generally resistant to chemicals and corrosion.
