Q:Can galvanized pipe be welded with seamless steel tube? What should I do to connect?: See the galvanized pipe and seamless steel pipe steel that differences in how if the difference is too large then the steel used for two kinds of materials for welding requirements is not the same, do not recommend direct welding, low pressure can be used in high voltage wire, welding on both sides of the same material flange with flange connection.

Q:How are steel pipes manufactured?: Steel pipes are manufactured through a process called pipe manufacturing, which involves several steps. First, raw materials such as steel plates or coils are formed into cylindrical shapes. These shapes are then welded together to create a seamless or welded pipe. After welding, the pipes undergo heat treatment to improve their mechanical properties. Finally, the pipes are cut, inspected, and coated with protective layers before being ready for various applications.

Q:What is the diameter of the steel tube DN20?: The symbol is DN, the unit is mm, but omitted to write. Also available in English in.

Q:Can steel pipes be used for underground water supply?: Yes, steel pipes can be used for underground water supply. Steel pipes are strong, durable, and resistant to corrosion, making them suitable for various applications, including underground water supply. However, it is important to use steel pipes that are specifically designed for underground use and are coated or lined to prevent corrosion. Additionally, proper installation and maintenance are crucial to ensure the long-term integrity and functionality of the steel pipes in an underground water supply system.

Q:How do you protect steel pipes from fire?: One way to protect steel pipes from fire is by applying a fire-resistant coating or insulation. This can help prevent the pipes from reaching the critical temperature where structural integrity is compromised. Additionally, installing fire rated enclosures or barriers around the pipes can provide an extra layer of protection. Regular inspections and maintenance are also crucial to ensure any potential fire hazards are identified and addressed promptly.

Q:How are steel pipes cleaned and flushed?: Depending on specific requirements and conditions, different methods can be used to clean and flush steel pipes. One way to achieve this is through mechanical cleaning, which involves physically removing debris, rust, or scale from the inner surface of the pipes using wire brushes, scrapers, or other abrasive tools. This method is effective in removing loose or easily detachable contaminants. Chemical cleaning is another commonly used method, especially for pipes with stubborn deposits or rust. Various chemicals or cleaning agents are flushed through the pipes to dissolve or loosen the buildup, which can then be washed away. Acid-based solutions are often used for this purpose, but it's crucial to select the appropriate chemical and concentration to prevent pipe damage. High-pressure water jetting is an effective technique for cleaning and flushing steel pipes. Water is pumped at high pressure through a nozzle, generating a powerful jet that dislodges and removes debris or deposits from the pipe walls. This method is particularly useful for eliminating hard or compacted materials that are difficult to remove by other means. In some cases, a combination of these methods may be necessary to achieve the desired cleanliness. For example, mechanical tools can be used for pre-cleaning, followed by chemical cleaning or high-pressure water jetting to ensure thorough flushing and contaminant removal. Regular maintenance and cleaning of steel pipes are crucial to maintain efficiency and prevent corrosion. It's important to adhere to proper procedures and safety guidelines when cleaning and flushing steel pipes to achieve effective results and prevent any damage to the pipes.

Q:How are steel pipes used in construction?: Steel pipes are commonly used in construction for various purposes such as structural supports, plumbing systems, and underground utility installations. They provide strength, durability, and resistance to corrosion, making them ideal for carrying fluids, gases, and other materials. Additionally, steel pipes can be easily welded, allowing for efficient and secure connections in building frameworks and infrastructure.

Q:SC15 what does galvanized steel pipe look like?: Zinc plating: galvanized steel pipe hot galvanized and galvanized two kinds, hot galvanized, zinc coating thickness, with uniform coating, adhesion, long service life and so on. The cost of galvanizing is low, the surface is not very smooth, and the corrosion resistance of itself is much better than that of galvanized pipe. Refer to

Q:What are the different standards for steel pipes?: There are several different standards for steel pipes, including ASTM (American Society for Testing and Materials), API (American Petroleum Institute), and ASME (American Society of Mechanical Engineers). These standards specify the requirements for various aspects of steel pipes, such as their dimensions, chemical composition, mechanical properties, and testing procedures. These standards ensure that steel pipes meet the necessary quality and safety standards for their intended applications.

Q:What are the different types of steel pipe supports for seismic applications?: Some of the different types of steel pipe supports for seismic applications include sway braces, rigid braces, snubbers, and spring hangers.
