1、Structure of Hollow Section Description:
Hollow section is a type of metal profile with a hollow tubular cross section. Hollow section, especially rectangular sections, are commonly used in welded steel frames where members experience loading in multiple directions. Square and circular hollow section have very efficient shapes for this multiple-axis loading as they have uniform geometry along two or more cross-sectional axes, and thus uniform strength characteristics. This makes them good choices for columns. They also have excellent resistance to torsion. Hollow section can also be used as beams, although wide flange or I-beam shapes are in many cases a more efficient structural shape for this application. However, the hollow section has superior resistance to lateral torsional buckling.
2、Main Features of the Hollow Section:
• High manufacturing accuracy
• High strength
• Small inertia resistance
• Strong heat dissipation ability
• Good visual effect
•Reasonable price

- Q:What is the lifespan of galvanized steel pipes?
- The lifespan of galvanized steel pipes can vary depending on various factors such as the quality of the galvanization, the environment in which they are installed, and the maintenance they receive. However, on average, galvanized steel pipes can last between 40 to 70 years.
- Q:How do you calculate the flow velocity in a steel pipe?
- The flow velocity in a steel pipe can be calculated using the equation: velocity = (flow rate) / (cross-sectional area of the pipe).
- Q:What are the common standards for manufacturing steel pipes?
- The common standards for manufacturing steel pipes include specifications set by international organizations such as the American Society for Testing and Materials (ASTM), the International Organization for Standardization (ISO), and the European Committee for Standardization (EN). These standards cover aspects such as material composition, dimensions, mechanical properties, and testing methods to ensure quality and compatibility in steel pipe production.
- Q:What is the role of steel pipes in HVAC systems?
- Steel pipes are crucial components in HVAC systems as they are used to transport hot and cold water throughout the system. They provide a durable and reliable means of distributing heat or cooling energy to various parts of a building. Steel pipes are known for their high strength and resistance to corrosion, making them an ideal choice for HVAC applications.
- Q:How do steel pipes compare to other materials like PVC or copper pipes?
- Steel pipes are known for their durability and strength, making them highly preferable for applications that require high pressure and extreme temperatures. In comparison to PVC pipes, steel pipes offer superior resistance to impact, corrosion, and fire, making them suitable for harsh environments. Copper pipes, on the other hand, are primarily used for plumbing and heating systems due to their excellent heat conductivity. While steel pipes may be more expensive than PVC or copper, their robustness and longevity make them a reliable choice for various industrial and infrastructure projects.
- Q:What is the difference between black steel pipe and galvanized steel pipe?
- The main difference between black steel pipe and galvanized steel pipe lies in their coating. Black steel pipe is untreated and has a dark, matte appearance, while galvanized steel pipe is coated with a layer of zinc to prevent rusting and has a silver, shiny appearance. This coating makes galvanized steel pipes more durable and suitable for outdoor use, while black steel pipes are commonly used for indoor plumbing and gas lines.
- Q:What kinds of steel pipe are divided into?
- The steel pipe seamless steel pipe and welded steel pipe (tube) two categories. According to the section shape and can be divided into round tube shaped tube, round steel pipe is widely used, but there are also some square, rectangular, semicircular, hexagonal, triangular, octagonal shaped steel tube.Seamless steel pipe: seamless steel pipe is ingot or solid billet made by capillary hole, then hot, cold or cold drawing. Made of seamless steel pipe specifications with outer diameter * wall thickness mm. Number of seamless steel pipe cold and hot points of seamless steel pipe (DIAL) two categories.
- Q:How are steel pipes insulated to prevent heat gain?
- Steel pipes are insulated to prevent heat gain by applying a layer of thermal insulation material around them. This insulation material acts as a barrier, preventing the transfer of heat from the surrounding environment to the steel pipes. Additionally, the insulation is often covered with a protective outer layer to enhance its durability and resistance to external factors.
- Q:What are the safety precautions to follow when working with steel pipes?
- When working with steel pipes, it is important to follow several safety precautions to ensure the well-being of yourself and those around you. These precautions include: 1. Personal Protective Equipment (PPE): Always wear the appropriate PPE when working with steel pipes. This includes safety glasses, gloves, steel-toed boots, and a hard hat. PPE helps protect you from potential hazards such as flying debris, falling objects, and sharp edges. 2. Proper Lifting Techniques: Steel pipes can be heavy and awkward to handle. Always use proper lifting techniques to avoid strain or injury. Bend your knees, keep your back straight, and use your legs to lift the pipes. If a pipe is too heavy to lift on your own, ask for assistance or use mechanical lifting equipment. 3. Secure Working Area: Ensure that the work area is clean, organized, and free from tripping hazards. Keep the floor clear of tools, debris, and other obstructions that may cause accidents. Additionally, barricade or cordon off the work area to prevent unauthorized access and ensure the safety of others. 4. Use Proper Tools and Equipment: Use the right tools and equipment for the job. This includes using wrenches, pipe cutters, and clamps designed specifically for steel pipes. Using improper tools can lead to accidents, damage to the pipes, or faulty connections. 5. Proper Storage: Store steel pipes in a secure and organized manner to prevent them from falling or rolling onto someone. Stack the pipes in a stable position, and use racks or supports to ensure they are not at risk of toppling over. 6. Secure Connections: When joining steel pipes, ensure that the connections are properly secured. This includes using appropriate fittings, tight fasteners, and following the recommended torque specifications. Loose or improperly secured connections can result in leaks, bursts, or other failures. 7. Proper Ventilation: If working in an enclosed space, ensure adequate ventilation to prevent the buildup of harmful gases or fumes. Welding or cutting steel pipes can release hazardous gases, so make sure the area is properly ventilated or use respiratory protection if necessary. 8. Fire Safety: Steel pipes can become extremely hot during welding or cutting processes. Have fire extinguishers readily available and know how to use them. Clear any flammable materials from the work area and be cautious of sparks or open flames. 9. Regular Inspections: Regularly inspect steel pipes for signs of damage, such as cracks, rust, or degradation. Replace any damaged or compromised pipes to avoid potential failures or accidents. By following these safety precautions, you can minimize the risks associated with working with steel pipes and ensure a safe working environment. Remember, safety should always be the top priority.

Seamless Steel Pipes: These pipes are manufactured without any welded seams and are often preferred for applications requiring high pressure, high temperature, or a smooth inner surface. Industries such as oil and gas, automotive, and aerospace frequently utilize seamless steel pipes. 6. Welded Steel Pipes: These pipes are created by welding two steel pieces together. They are available in various shapes and sizes and commonly used in construction, water supply systems, and general engineering applications. 7. ERW (Electric Resistance Welded) Steel Pipes: These pipes are produced by passing a high-frequency electric current through a steel strip and then welding the edges together. ERW steel pipes find wide usage in oil and gas transportation, structural applications, and fencing. 8. LSAW (Longitudinal Submerged Arc Welded) Steel Pipes: These pipes are formed by bending and welding a steel plate into a cylindrical shape. LSAW steel pipes are commonly employed in large-scale infrastructure projects such as oil and gas pipelines and bridge construction. To summarize, the market offers a variety of steel pipes, including carbon steel, stainless steel, alloy steel, galvanized steel, seamless steel, welded steel, ERW steel, and LSAW steel pipes.
