1Structure of Seamless Steel Pipes with High Quality Made in China: 

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 are the different types of steel pipe end connections?
There are several types of steel pipe end connections, including threaded, socket weld, butt weld, flanged, and grooved connections.
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
Previously used steel pipe GB 51*3.0mm, the latest national standard JGJ130-2001 stipulates that the use of steel pipe for construction projects need to be 48*3.5mm specifications, the wall thickness should be 3.5mm square for qualified products.
Q:What are the different types of steel pipe coatings for underground gas pipelines?
There are several types of steel pipe coatings commonly used for underground gas pipelines, including fusion-bonded epoxy (FBE) coating, polyethylene (PE) coating, and polyurethane (PU) coating. Each coating provides different levels of protection against corrosion and abrasion, ensuring the longevity and integrity of the gas pipeline.
Q:How do steel pipes handle expansion and contraction?
Steel pipes handle expansion and contraction through their inherent elasticity and ability to withstand high temperatures. When exposed to heat, steel pipes expand due to thermal expansion, and when cooled, they contract due to thermal contraction. This expansion and contraction are accommodated by the flexibility of the steel material, allowing it to withstand the changes in size without significant damage or deformation. Additionally, proper installation techniques such as the use of expansion joints and loops can also help accommodate the expansion and contraction of steel pipes, ensuring their integrity and longevity.
Q:What are the factors to consider when selecting a steel pipe for a specific application?
When selecting a steel pipe for a specific application, there are several factors that need to be considered. These factors include the required strength and durability, the intended use and environment, the size and dimensions needed, the corrosion resistance properties required, the temperature and pressure conditions, and the budget available for the project. By taking all these factors into account, one can choose the most suitable steel pipe that meets the specific requirements of the application.
Q:How are steel pipes protected against external corrosion in coastal areas?
To safeguard steel pipes against external corrosion in coastal regions, a combination of coating and cathodic protection methods is employed. An effective approach involves applying a protective coating onto the steel surface, forming a barrier against corrosive elements like saltwater and humidity present in the coastal environment. Commonly used coating materials, such as epoxy or polyethylene, possess corrosion-resistant properties and offer long-lasting protection. Furthermore, cathodic protection is utilized to enhance the corrosion resistance of the steel pipes. This technique employs sacrificial anodes or impressed current to prevent corrosion. Sacrificial anodes, typically made of zinc or aluminum, are attached to the steel pipe and corrode in place of the steel, sacrificing themselves to safeguard the steel surface. On the other hand, impressed current systems rely on an external power source to provide a protective current, effectively preventing corrosion. Ensuring the effectiveness of the protective coating and cathodic protection system necessitates regular inspection and maintenance. Coatings may degrade over time due to wear and tear, requiring periodic evaluation and reapplication if necessary. Similarly, sacrificial anodes must be replaced when depleted, and impressed current systems need to be monitored and adjusted to maintain the desired level of protection. By combining the application of durable coatings with cathodic protection measures, steel pipes in coastal areas can be adequately shielded against external corrosion, promoting their durability and optimal performance.
Q:How are steel pipes used in natural gas processing plants?
Steel pipes are used in natural gas processing plants to transport and distribute natural gas from one point to another within the facility. These pipes are capable of withstanding high pressure and temperature, ensuring the safe and efficient flow of the gas throughout the plant. Additionally, steel pipes are resistant to corrosion, which is crucial as natural gas can be corrosive. They are also used for connecting various equipment and components in the processing plant, allowing for the smooth operation of the entire system.
Q:What are the different grades of steel used in pipes?
The different grades of steel used in pipes vary based on their composition and properties. Some common grades include carbon steel (such as ASTM A106 or API 5L), stainless steel (such as ASTM A312 or ASTM A269), and alloy steel (such as ASTM A335). Each grade has specific characteristics that make it suitable for different applications, such as high temperature or corrosive environments.
Q:Are steel pipes suitable for high-temperature applications?
Yes, steel pipes are suitable for high-temperature applications. Steel has excellent thermal conductivity and can withstand high temperatures without losing its structural integrity. Additionally, steel pipes have high tensile strength and can resist thermal expansion and contraction, making them ideal for transporting hot liquids or gases in industrial processes.
Q:How much is the tube?
The theoretical weight calculation formula of ordinary carbon steel tube is:The weight of each meter is kg/m= (outer diameter mm-, wall thickness mm) * wall thickness mm*0.02466For example: inventory 20# pipe diameter of 108*4.5 weight per meter:Kg/m= (108-4.5) *4.5*0.02466=11.485In accordance with the diameter of 108*4.5 steel pipe market price is 4500 yuan / ton as an example, we can know the diameter of 108*4.5 steel pipe per meter price: 11.485*4.5=51.68 yuan.
