Q: What is the theoretical weight per square meter of the steel pipe diameter of the outer frame and the thickness of the tube wall 3mm 48mm?: The outer steel tube diameter is 48mm, the tube wall thickness is 3mm, the theoretical weight per meter is 3.3291kgCalculation formula: (outside diameter wall thickness) * wall thickness *0.02466(48-3) *3*0.02466=3.3291kg

Q: Does the seamless steel pipe need rust removal?: Chemical and electrolytic methods are generally used for pickling treatment. The pipeline corrosion only uses chemical pickling, which can remove oxide, rust and old coating. Sometimes, it can be treated as sand blasting after rust removing. Two. Although chemical cleaning can make the surface reach a certain degree of cleanliness and roughness, but its anchor grain is shallow, and easy to pollute the environment.

Q: What is the role of steel pipes in the mining and extraction of minerals?: Steel pipes play a critical role in the mining and extraction of minerals as they are used for various applications throughout the process. These durable pipes are commonly employed to transport and distribute water, chemicals, and compressed air to different areas of the mine. Additionally, steel pipes are utilized in the construction of mine shafts, tunnels, and underground structures, providing stability and support. Their ability to withstand harsh conditions, resistance to corrosion, and high strength make steel pipes an indispensable component in the mining industry.

Q: What are the common sizes of steel pipes?: The common sizes of steel pipes vary widely, but some common diameters range from 1/8 inch to 36 inches, with wall thicknesses typically ranging from Schedule 10 to Schedule 160.

Q: How do steel pipes perform in extreme weather conditions?: Steel pipes generally perform well in extreme weather conditions. They have high strength and durability, making them resistant to harsh weather elements such as extreme temperatures, heavy rainfall, and strong winds. The material's resistance to corrosion and rust also ensures that the pipes can withstand long-term exposure to moisture and other environmental factors. However, it is important to note that proper maintenance and protective coatings can further enhance their performance and lifespan in extreme weather conditions.

Q: What's the difference between stainless steel seamless tube and stainless steel welded pipe?: Stainless steel seamless steel tube is a kind of steel strip with hollow section and without seams.

Q: What are the applications of steel pipes in the automotive industry?: Steel pipes are commonly used in the automotive industry for various applications such as exhaust systems, fuel lines, and structural components. They offer excellent durability, corrosion resistance, and high tensile strength, making them ideal for carrying fluids and withstanding harsh environments. Additionally, steel pipes can be easily formed and welded, allowing for efficient manufacturing and assembly processes in the automotive sector.

Q: What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?: 200 refers to the diameter of the pipe. Personally, you should be an electrical professional, but the electrical specialty rarely uses the 200 pipe diameter unless it is used when the buried cable passes the road;

Q: How can seamless steel tubes be produced?: Seamless steel tubes are made of ingots or billets made by piercing and are then made by hot rolling, cold rolling or cold casting. Seamless steel tube plays an important role in the steel tube industry of our country. According to incomplete statistics, China's existing seamless tube production enterprises about more than 240, seamless steel pipe units about more than 250 units, with an annual output capacity of about about 4500000 tons. From the caliber, 35% of phi 76, less than phi 159-650, accounting for 25%. From the species point of view, the general use of 1 million 900 thousand tons of pipe, accounting for 54%; oil pipe 760 thousand tons, accounting for 5.7%; hydraulic props, precision pipe 150 thousand tons, accounting for 4.3%; stainless steel pipe, bearing tube, automobile tube 50 thousand tons, accounting for 1.4%.

Q: Can steel pipes be used for the construction of dams?: Yes, steel pipes can be used for the construction of dams. Steel pipes are often used in dam construction for various purposes such as water intake and outlet structures, penstocks, and spillway gates. They offer durability, strength, and resistance to corrosion, making them suitable for withstanding the high pressures and harsh environments associated with dam construction.
