1、Structure of Hot Rolled Seamless Steel pipe Made in China from CNBM:
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: How are steel pipes protected against mechanical damage during transportation?
- Various measures are implemented to safeguard steel pipes against mechanical damage during transportation. One commonly used technique involves the application of protective coatings or wrapping materials, typically composed of plastic, rubber, or epoxy. These coatings serve as a physical barrier, shielding the pipes from scratches, dents, and other forms of mechanical harm. Another method involves the utilization of padding or cushioning materials, such as foam inserts or rubber gaskets. These materials are inserted inside or wrapped around the pipes, absorbing any impacts or shocks that may occur during transportation. This effectively prevents potential damage caused by vibrations or bumps. Additionally, steel pipes are frequently secured and immobilized within transportation containers through the use of straps, braces, or other securing devices. These measures ensure that the pipes remain stable and do not collide with one another, thereby minimizing the risk of mechanical harm. Furthermore, proper handling and loading techniques play a crucial role in protecting steel pipes during transportation. This involves the utilization of appropriate lifting equipment, such as cranes or forklifts, to prevent any accidental dropping or mishandling of the pipes. Moreover, pipes are often stored or stacked in a manner that minimizes the possibility of deformation or bending. Ultimately, a combination of protective coatings, cushioning materials, securement devices, and proper handling techniques are employed to ensure the safe transportation of steel pipes and maintain their optimal condition for use in various applications.
- Q: How are steel pipes used in the construction of underground parking structures?
- Steel pipes are commonly used in the construction of underground parking structures for various purposes. They are primarily utilized for the installation of underground drainage systems, including stormwater and wastewater pipes. Steel pipes are also employed for the construction of support columns and beams, providing structural stability to the parking structure. Additionally, steel pipes are used for the installation of fire protection systems, such as sprinkler pipes, ensuring the safety of the underground parking facility.
- Q: How are steel pipes insulated to prevent heat gain?
- Steel pipes are insulated to prevent heat gain by using materials with low thermal conductivity, such as fiberglass or mineral wool, which are wrapped around the pipes. This insulation layer acts as a barrier, reducing the transfer of heat from the surroundings to the pipes, thereby minimizing heat gain. Additionally, a vapor barrier may be applied over the insulation to prevent moisture ingress, which could further impact the insulation's effectiveness.
- Q: How are steel pipes sized and classified?
- The primary criteria for sizing and categorizing steel pipes are their outer diameter (OD) and wall thickness. This standardization ensures compatibility and ease of use across different applications. The common approach to sizing steel pipes is through nominal pipe size (NPS), a North American standard that refers to a pipe's OD. NPS sizes span from 1/8 inch to 36 inches, with each size corresponding to a specific OD. For instance, a 1/2-inch NPS pipe has an OD of 0.84 inches, while a 12-inch NPS pipe has an OD of 12.75 inches. It's important to note that the pipe's OD may not precisely match its actual measurement due to historical dimensions. Moreover, steel pipes are categorized into various schedules, which indicate the wall thickness. The most common schedules are SCH 5, SCH 10, SCH 40, SCH 80, and SCH 160, with higher numbers representing thicker walls. These schedules are standardized and aid in selecting the appropriate pipe for specific applications. Additionally, steel pipes can be further classified based on their end connections. The typical types include threaded, plain-end, and socket-weld connections. Threaded pipes possess screw threads on both ends, facilitating easy assembly and disassembly. Plain-end pipes lack threads and are typically joined using welding techniques. Socket-weld pipes have a socket-like end that enables welding with a corresponding fitting. In conclusion, steel pipes undergo sizing and classification based on their outer diameter, wall thickness, and end connections. The nominal pipe size (NPS) denotes the outer diameter, while the schedule number represents the wall thickness. Understanding the sizing and classification of steel pipes is crucial when selecting the appropriate pipe for specific applications in industries like construction, oil and gas, plumbing, and manufacturing.
- Q: How to distinguish between steel pipe and spiral pipe material?
- Steel pipe according to the pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.Carbon tube can be divided into ordinary carbon steel tube and high quality carbon structure tube.
- Q: How are steel pipes used in the construction of bridges?
- Steel pipes are commonly used in the construction of bridges as they provide structural support and stability. They are often used as piers or columns to bear the weight of the bridge deck and transfer the load to the foundation. Additionally, steel pipes are used for the construction of bridge railings and barriers, providing safety for pedestrians and vehicles. Overall, steel pipes offer durability, strength, and flexibility, making them an essential component in bridge construction.
- Q: How are steel pipes used in the aerospace manufacturing industry?
- Steel pipes are commonly used in the aerospace manufacturing industry for various purposes such as hydraulic systems, fuel lines, and structural components. They offer excellent strength, durability, and resistance to high temperatures, making them ideal for carrying fluids and supporting the overall structure of aircraft.
- Q: What are the different types of steel pipe end connections?
- There are several types of steel pipe end connections, including threaded, welded, flanged, grooved, and compression fittings.
- Q: Can steel pipes be used for nuclear power plants?
- Yes, steel pipes can be used for nuclear power plants. Steel is commonly used in the construction of nuclear power plants due to its strength, durability, and resistance to high temperatures and pressures. However, the specific type of steel and its properties must meet the rigorous safety and quality standards set by regulatory bodies to ensure the integrity and reliability of the nuclear power plant.
- Q: How are steel pipes protected against fire?
- Steel pipes are typically protected against fire through the application of fire-resistant coatings or by encasing them in fire-rated materials, such as concrete or gypsum board. Additionally, fire sprinkler systems or fire-resistant insulation may be installed around the pipes to provide an added layer of protection.
