1Structure of 

Seamless steel pipe a variety of high quality  ASTM

Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.

Q: What does "steel pipe SC" mean?
DN100 and "SCH80" refer to the outer diameter and the wall thickness of the steel pipe;
Q: What is DN50 for welded pipe?
Refers to the use of welded steel pipe made of DN50 steel pipe, refers to the inside diameter is 50mm, the market of common DN50 pipe also refers to the 2 inch pipe, standard pipe: 3.5mm thickness, pipe diameter 60mm, the weight of 4.88kg/m theory. DN50 seamless steel pipe, commonly used in the market, has two specifications: 57mm, 60mm, and if no special instructions, 57mm is commonly used. The outer diameter of the welded pipe is only 60mm this specification.
Q: What is the difference between the stainless steel pipe welded pipe and seamless pipe?
Grain size: usually, the grain size of the metal is related to the heat treatment temperature and the time at which the metal is kept at the same temperature. Therefore, the welded pipe and seamless tube annealing of the same grain size. If the minimum tube cold treatment, the grain size of the weld metal is smaller than the grain size, welding or grain size is the same.Strength: the strength of the pipeline in the composition of the alloy and alloy containing the same and the same heat treatment of seamless tube and seamed tube essentially consistent strength. After the tensile test and three-dimensional vibration test, tube tearing almost all occurred in the welding point or away from the heated area where. This is because there is little impurity in the weld and the nitrogen content is slightly higher, so the strength of the welded joint is better than that of other parts. However, the ASME Boiler and Pressure Vessel Association believes that the seamed tube can withstand 85% of the allowable pressure, which is mainly due to improved welding equipment data collection prior to today. The provisions of ASME 100% completely under license by ultrasonic testing pressure tube. Similarly, Europe and Asia also stipulates that can ensure the quality of welding performance by eddy current test tube, the eddy current testing is subject to legal procedures and licensed institutions. Trent's eddy current test was approved by the Swedish power division. ASME believes the current loss is relatively small, high-quality performance based on the seamed tube.
Q: What is the purpose of pipe flanges in steel pipes?
The purpose of pipe flanges in steel pipes is to provide a secure and leak-proof connection between two pipes or to other equipment, such as valves or pumps. Flanges allow for easy assembly and disassembly of pipe sections, as well as providing a means for maintenance and repairs. Additionally, they provide a stronger connection, ensuring the integrity and stability of the pipeline system.
Q: How are steel pipes coated to prevent external corrosion?
Steel pipes are commonly coated to prevent external corrosion through various methods such as galvanization, epoxy coating, or polyethylene wrapping. These coatings act as barriers between the steel surface and the external environment, protecting the pipes from moisture, chemicals, and other corrosive elements.
Q: What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
GB/T3091-2008: DN150 welded steel pipe, wall thickness of 6mm, the theory of the weight of welded steel pipe 24.02kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 6mm, C=1.02, DN150, theoretical weight and wall thickness of 6mm galvanized steel 1.02*24.02= 24.5kg/m.
Q: Why should the weak electricity be pre buried with galvanized steel pipe?
Galvanized steel is widely used in construction, machinery, coal, chemical industry, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.
Q: What is the difference between schedule 10 and schedule 40 steel pipes?
Schedule 10 and schedule 40 steel pipes are both commonly used in various industries for different purposes. The main difference lies in their wall thickness and pressure ratings. Schedule 10 steel pipes have a thinner wall compared to schedule 40 pipes. This means that schedule 10 pipes have a smaller internal diameter and can handle less pressure compared to schedule 40 pipes. The wall thickness of schedule 10 pipes is typically 0.109 inches, while schedule 40 pipes have a wall thickness of 0.154 inches. Due to their thinner walls, schedule 10 pipes are primarily used for low-pressure applications such as domestic water supply, drainage systems, and general plumbing. They are also commonly used for lightweight structures or where weight is a concern. On the other hand, schedule 40 pipes are designed to handle higher pressure and are often used in industrial applications, including oil and gas pipelines, chemical processing plants, and high-pressure fluid systems. The thicker walls of schedule 40 pipes provide them with increased strength and durability to withstand higher pressure and stress. In summary, the main difference between schedule 10 and schedule 40 steel pipes is their wall thickness and pressure ratings. Schedule 10 pipes have a thinner wall and are suitable for low-pressure applications, while schedule 40 pipes have a thicker wall and can handle higher pressure. It is important to choose the appropriate schedule based on the specific requirements and pressure limitations of the intended application.
Q: How are steel pipes used in the construction of coal-fired power plants?
Steel pipes are commonly used in the construction of coal-fired power plants for various purposes. They are utilized for transporting coal and other fuels, as well as for carrying water and steam in the power generation process. Steel pipes are also used in the construction of the plant's cooling system, helping to circulate water and dissipate heat. Additionally, they are employed in the construction of the plant's exhaust system, facilitating the removal of combustion byproducts. In summary, steel pipes play a crucial role in the infrastructure of coal-fired power plants, enabling efficient fuel transportation, heat exchange, and waste management.
Q: How seamless steel tube is formed?
Hot drawing or cold drawing. The so-called cold is the billet from the thick wall tube is not heated, oil lubrication, with a steel sleeve inside, gradually elongated. Hot drawing is to make the billet tube red, do such work, generally thick wall applicable.
