Q:Can steel pipes be used for cooling systems?: Yes, steel pipes can be used for cooling systems. Steel pipes are commonly used in various industrial cooling applications due to their durability, high strength, resistance to corrosion, and ability to withstand high pressure and temperature conditions.

Q:How are steel pipes threaded for connection?: Steel pipes are threaded for connection using a process called threading, which involves cutting helical grooves into the pipe's surface. This is typically done using a machine called a pipe threading machine, which rotates the pipe while a cutting tool is held against it, creating the desired threading pattern. The threaded ends of the pipes can then be connected using fittings or couplings to create a secure and leak-proof joint.

Q:What is the maximum allowable stress for steel pipes?: The maximum allowable stress for steel pipes depends on various factors such as the grade of steel, diameter, wall thickness, and the intended application. It is typically determined by industry standards and codes, such as the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code. Therefore, there is no one-size-fits-all answer to this question.

Q:What is the difference between ERW (Electric Resistance Welded) and LSAW (Longitudinal Submerged Arc Welded) steel pipes?: ERW steel pipes are manufactured by high-frequency electrical currents passing through the metal, resulting in a welded joint. On the other hand, LSAW steel pipes are produced by submerging a metal plate into a welding zone, creating a welded joint through the use of a welding arc. The main difference lies in the welding process, with ERW pipes being more suitable for small to medium-sized diameters, while LSAW pipes are commonly used for larger diameter and thicker-walled applications.

Q:What is the difference between steel pipes and PVC-U pipes?: Steel pipes and PVC-U pipes differ in their composition, durability, and application. Steel pipes are made from iron and carbon, providing them with high strength and resistance to extreme conditions. They are commonly used for transporting water, gas, and oil in industrial settings due to their durability and ability to withstand high pressure and temperature. PVC-U pipes, on the other hand, are made from a synthetic plastic called polyvinyl chloride. They are lightweight, corrosion-resistant, and easy to install, making them ideal for residential plumbing, irrigation systems, and drainage. While steel pipes are more robust and suitable for heavy-duty applications, PVC-U pipes are cost-effective, versatile, and suitable for lighter applications.

Q:What are steel pipes used for?: Steel pipes are commonly used for transporting fluids and gases, as well as for structural applications such as construction, oil and gas exploration, and plumbing systems.

Q:What is the difference between steel pipes and cast iron soil pipes?: Steel pipes and cast iron soil pipes are both used for plumbing and drainage systems, but they differ mainly in their material composition and durability. Steel pipes are typically made from an alloy of iron and carbon, which provides them with high strength and resistance to corrosion. On the other hand, cast iron soil pipes are made solely from iron, making them more susceptible to rust and corrosion over time. Additionally, steel pipes are generally lighter, easier to handle, and more flexible than cast iron soil pipes. However, cast iron soil pipes are known for their superior soundproofing properties, making them a preferred choice in buildings where noise reduction is crucial.

Q:How seamless steel tube is formed?: Seamless steel tubes are formed by cold drawing and hot rolling.

Q:45 and 316 which steel tubes are of high hardness?: 316 stainless steel by adding Mo element, the corrosion resistance, and high temperature strength has greatly improved, high temperature can reach 1200-1300 degrees, can be used in severe conditions. 316F stainless steel is easy to cut stainless steel with high sulfur content. Good corrosion resistance, easy processing, good smoothness, suitable for axial parts.

Q:What are the different testing methods used for steel pipes?: There are various testing methods used for steel pipes, including non-destructive testing methods such as ultrasonic testing, magnetic particle testing, radiographic testing, and liquid penetrant testing. These methods help detect any defects or flaws in the pipes, ensuring their quality and integrity. Additionally, destructive testing methods such as tensile testing, impact testing, and hardness testing are also used to evaluate the mechanical properties of the steel pipes.
