1Structure of Seamless Pipe: 

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 regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.

 

2‍‍Main Features of the Seamless Pipe :

• High manufacturing accuracy

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

Q:How are steel pipes measured and labeled?
Steel pipes are typically measured and labeled based on their outside diameter (OD) and wall thickness. The measurement is usually expressed in millimeters or inches. The label includes these dimensions, such as "2-inch OD, 1/8-inch wall thickness." Additionally, the length of the pipe may also be included in the labeling, ranging from standard lengths like 6 meters or 20 feet.
Q:How are steel pipes used in HVAC systems?
Steel pipes are used in HVAC systems for various purposes such as transporting hot or cold water, steam, or refrigerant throughout the system. They are commonly used for supply and return lines, as well as for connecting various HVAC components like chillers, boilers, air handlers, and heat exchangers. Steel pipes are preferred in HVAC systems due to their durability, strength, and resistance to corrosion and high pressure.
Q:How seamless steel tube is formed?
Overview of two kinds of steel pipe process:1, cold drawing (rolling) seamless steel pipe: round tube to heating to perforation, annealing, pickling, leading to oil (copper), multi pass drawing (Leng Zha), the blank pipe, heat treatment, straightening, pressure test (testing), marking and warehousing.2. Hot rolling (extrusion seamless steel tube): round tube billet, heating, piercing, three roll cross rolling, rolling or extrusion, removal of pipe, sizing, reducing (diameter or reducing), cooling, blank tube, straightening, water pressure test (or flaw detection), marking and warehousing.
Q:Can steel pipes be used for structural supports in buildings?
Yes, steel pipes can be used for structural supports in buildings. Steel pipes are commonly used in construction due to their high strength, durability, and ability to withstand heavy loads. They provide excellent structural support, especially in applications that require long spans or high load-bearing capacities. Additionally, steel pipes are resistant to corrosion and can be easily connected or welded, making them a popular choice in building construction.
Q:How are steel pipes used in the pharmaceutical industry?
Steel pipes are commonly used in the pharmaceutical industry for various purposes, such as transporting liquids and gases, transferring raw materials and finished products, and providing a reliable and durable infrastructure for the pharmaceutical manufacturing process.
Q:Can steel pipes be recycled and used for other purposes?
Yes, steel pipes can be recycled and used for other purposes. Due to their durability and strength, steel pipes can be melted down and repurposed for various applications, including construction, manufacturing, and infrastructure projects. Recycling steel pipes not only saves resources but also contributes to reducing waste and promoting sustainability.
Q:Can steel pipes be used for underground gas storage?
Yes, steel pipes can be used for underground gas storage. Steel pipes are commonly used for transporting and storing various types of gases, including natural gas, due to their strength, durability, and resistance to corrosion. They are able to withstand high pressures and can be designed to meet the specific requirements of underground gas storage facilities. Additionally, steel pipes can be coated or lined with materials to further enhance their resistance to corrosion and to prevent any potential leaks. However, it is important to ensure that proper safety measures and regulations are followed during the construction and operation of underground gas storage facilities to prevent any potential risks or hazards.
Q:How are steel pipes protected against microbial corrosion?
Steel pipes are protected against microbial corrosion through various methods, such as applying protective coatings or linings on the pipes' inner and outer surfaces. These coatings act as a barrier, preventing the contact of microorganisms with the steel surface, thereby reducing the risk of microbial corrosion. Additionally, biocides and inhibitors can be added to the pipe's contents or injected into the pipeline to inhibit the growth and activity of microbes, further protecting the steel pipes from microbial corrosion.
Q:Are steel pipes resistant to vibration?
Yes, steel pipes are generally resistant to vibration due to their inherent strength and rigidity. However, the level of resistance can vary depending on factors such as pipe thickness, design, and installation. Additionally, the presence of external factors like fluid flow or mechanical forces can also affect the level of vibration resistance.
Q:What is the difference between hot-dip galvanizing and electroplating for steel pipes?
Hot-dip galvanizing and electroplating are both methods used to protect steel pipes from corrosion, but they differ in the process and the properties of the resulting coating. Hot-dip galvanizing involves immersing the steel pipe in a bath of molten zinc, which forms a thick and durable coating that bonds metallurgically with the steel. This provides excellent corrosion resistance and protection even in harsh environments. On the other hand, electroplating involves the deposition of a thin layer of zinc onto the steel pipe using an electric current. While electroplating also offers corrosion protection, the coating is typically thinner and less durable than hot-dip galvanizing. Hot-dip galvanizing is typically preferred for steel pipes that require long-lasting protection, while electroplating may be suitable for applications where a thinner coating is sufficient.
