- Q: What is the difference between internal and external coating for steel pipes?
- A protective layer is applied to the inner surface of steel pipes, which is known as internal coating. The main purpose of this coating is to prevent corrosion and enhance resistance against chemicals present in the fluid being transported. Techniques like spraying, brushing, or dipping are commonly used to apply the internal coating, and it can be made of materials such as epoxy, polyurethane, or cement mortar. On the contrary, external coating involves the application of a protective layer on the outer surface of steel pipes. The main objective of this coating is to protect against environmental factors like corrosion, abrasion, and impact. External coatings are usually applied through methods like wrapping or coating with materials such as polyethylene, fusion-bonded epoxy, or asphalt enamel. To summarize, the primary difference between internal and external coating for steel pipes lies in their location and purpose. Internal coatings safeguard the inner surface from corrosion and chemical attacks, while external coatings provide protection against environmental damage on the outer surface. Both types of coatings are essential to ensure the durability and reliability of steel pipes in various applications.
- Q: What is hot rolled steel pipe? What is a cold drawn steel tube?
- Seamless steel pipe, hot-rolled and cold-rolled (DIAL) seamless steel pipe two categories.Hot rolled steel tubes are divided into ordinary steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel pipes, stainless steel pipes, oil cracking pipes, geological steel pipes and other steel pipes, etc..Cold rolled seamless steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube and other steel tube, including carbon thin-walled steel, alloy thin-walled steel, stainless steel, thin steel tube. The outer diameter of hot-rolled seamless tube is generally greater than 32mm, the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless steel tube can reach 6mm, the wall thickness can be up to 0.25mm, the outer diameter of thin-wall pipe can be 5mm, the wall thickness is less than 0.25mm, and cold rolling has higher precision than hot rolling dimension.

- Q: Are steel pipes suitable for industrial cooling systems?
- Yes, steel pipes are generally suitable for industrial cooling systems. Steel is a strong and durable material that can withstand high pressure and temperature fluctuations commonly found in cooling systems. It has excellent resistance to corrosion, making it ideal for use with water or other coolants. Additionally, steel pipes have good thermal conductivity, allowing for efficient heat transfer in the cooling process. They are also readily available and cost-effective, making them a popular choice in industrial applications.
- Q: What is the difference between black steel pipes and galvanized steel pipes?
- The main difference between black steel pipes and galvanized steel pipes lies in their coating. Black steel pipes are uncoated and have a dark, iron oxide layer on their surface, while galvanized steel pipes are coated with a layer of zinc to protect against corrosion. This zinc coating gives galvanized pipes a shiny, silver appearance and makes them more resistant to rust and other environmental factors.
- Q: What is the impact of steel pipe size on flow rate and pressure?
- The size or diameter of a steel pipe has a significant impact on both flow rate and pressure. Firstly, the flow rate refers to the volume of fluid that can pass through the pipe per unit of time. A larger pipe diameter allows for a greater flow rate as there is more space for the fluid to move through. This is due to the fact that a larger cross-sectional area of the pipe offers less resistance to the flow of fluid. Therefore, increasing the size of the steel pipe will generally lead to an increase in flow rate. Secondly, the pressure within a pipe is influenced by its size. As the fluid flows through a pipe, it encounters resistance due to friction against the walls of the pipe. This resistance leads to a pressure drop along the length of the pipe. A smaller pipe diameter results in higher frictional losses, which leads to a greater pressure drop. On the other hand, a larger pipe diameter reduces frictional losses and therefore results in a lower pressure drop. Consequently, increasing the size of the steel pipe will generally lead to a decrease in pressure drop. It is important to note that while increasing the size of a steel pipe may generally result in a higher flow rate and lower pressure drop, there are other factors that can also affect these parameters. These include the fluid properties, the length and layout of the pipe, and any additional components such as valves or fittings. Therefore, it is crucial to consider all these factors and conduct proper calculations or simulations to accurately determine the impact of steel pipe size on flow rate and pressure in a specific system.
- Q: What materials are used in scaffolding pipes?
- Using 48.3 * 3.6mm steel pipe, the maximum thickness of the steel pipe shall not be less than 3.24mm (there should be no serious corrosion, bending, flattening or crack); the corrosion depth of the old steel pipe shall be in accordance with the construction fastener typeProvisions on the safety technical specification for steel pipe scaffold JGJ130-2011.
