Q: How are steel pipes protected against soil movement?: Steel pipes are protected against soil movement through various methods such as using casing pipes, employing anchor systems, implementing protective coatings, and utilizing concrete thrust blocks. These measures ensure that the steel pipes remain stable and secure in the event of soil movement.

Q: What is the difference between internal coating and external lining of steel pipes?: The main difference between internal coating and external lining of steel pipes lies in their purpose and location. Internal coating refers to the application of protective materials on the inner surface of the steel pipe, primarily to prevent corrosion, improve flow efficiency, and maintain the quality of transported fluids. On the other hand, external lining involves applying protective materials to the outer surface of the steel pipe, mainly for corrosion resistance, insulation, and protection against external elements. Therefore, while internal coating focuses on the interior protection and performance of the pipe, external lining shields the pipe from environmental factors and external damage.

Q: What are the different methods of inspecting steel pipes?: There are several methods of inspecting steel pipes, including visual inspection, ultrasonic testing, magnetic particle testing, dye penetrant testing, radiographic testing, and eddy current testing.

Q: Are steel pipes suitable for industrial applications?: Steel pipes are an excellent choice for industrial applications. They come with several advantages that make them the preferred option in various industries. Firstly, their strength and durability are exceptional, enabling them to withstand high pressure and heavy loads. This makes them perfect for transporting liquids, gases, and solids. Furthermore, steel pipes exhibit high resistance to corrosion, a critical feature in industrial settings where exposure to harsh chemicals, moisture, and extreme temperatures is common. Their corrosion-resistant properties ensure a longer lifespan and reduce the need for frequent maintenance and replacements. Additionally, steel pipes have a smooth interior surface, minimizing friction and allowing for efficient material flow. This is particularly vital in industries like oil and gas, where the smooth flow of fluids is essential for proper operations. Moreover, steel pipes offer a wide range of sizes and thicknesses, allowing for customization and flexibility in design. They can be easily welded and connected, facilitating simple installation and modification as per specific industrial requirements. Overall, steel pipes provide a combination of strength, durability, corrosion resistance, and versatility, making them highly suitable and widely used in various industrial applications such as oil and gas, construction, water treatment, power generation, and chemical processing.

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%.
