1Structure of Cold Drawned Seamless Steel pipe 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. 

 

2‍‍Main Features of Cold Drawned Seamless Steel pipe from CNBM:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

Q: What are the different types of steel coatings used for pipes?
Some of the different types of steel coatings used for pipes include epoxy coatings, polyethylene coatings, fusion bonded epoxy (FBE) coatings, and zinc coatings.
Q: Can steel pipes be used for the construction of high-rise buildings?
Yes, steel pipes can be used for the construction of high-rise buildings. Steel pipes offer several advantages such as high strength, durability, and resistance to fire and corrosion. They can be used for various structural elements including columns, beams, and bracing systems, providing a reliable and cost-effective solution for constructing tall buildings.
Q: Can steel pipes be used for transporting liquids?
Yes, steel pipes can be used for transporting liquids. Steel pipes are commonly used in various industries, including oil and gas, water supply, and sewage systems, due to their durability, strength, and resistance to corrosion. They are effective for transporting liquids such as water, oil, natural gas, and chemicals over long distances efficiently and safely.
Q: How are steel pipes coated for protection?
Steel pipes are commonly coated for protection using various methods such as galvanization, epoxy coating, and polyethylene wrapping. Galvanization involves immersing the pipes in a bath of molten zinc, forming a protective layer that prevents corrosion. Epoxy coating involves applying a layer of epoxy resin to the pipe surface, providing a barrier against moisture and chemicals. Polyethylene wrapping involves wrapping the pipes with a polyethylene material, offering insulation and protection against abrasion and corrosion. These coating methods ensure the longevity and durability of steel pipes, enhancing their resistance to environmental factors.
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: Can steel pipes be used for desalination plants?
Yes, steel pipes can be used for desalination plants. Steel pipes are commonly used in desalination plants to transport and distribute water, as they are durable, resistant to corrosion, and can handle high-pressure systems.
Q: How do you prevent corrosion in steel pipes?
One effective way to prevent corrosion in steel pipes is by applying a protective coating, such as paint or epoxy, to the surface of the pipes. This barrier creates a physical barrier between the pipe and the surrounding environment, preventing moisture and corrosive agents from coming into direct contact with the steel. Additionally, regular inspection and maintenance of the pipes, including cleaning and repairing any damaged coating, can help identify and address potential issues before they lead to corrosion.
Q: How are steel pipes used in the manufacturing of bridges?
Steel pipes are commonly used in the manufacturing of bridges for various purposes such as the construction of bridge piers, support columns, and structural elements. These pipes provide strength, durability, and flexibility to withstand heavy loads and harsh environmental conditions. They are often used to create the framework and support systems of the bridge, ensuring stability and longevity. Additionally, steel pipes may be used for the transportation of fluids, such as water or gas, across the bridge.
Q: What is the role of steel pipes in the construction of bridges?
The role of steel pipes in the construction of bridges is primarily to provide structural support and stability. Steel pipes are commonly used in bridge construction to form the framework and support the weight of the bridge deck and other components. They are also used to carry various utilities such as water, gas, and electricity across the bridge. Additionally, steel pipes are durable, resistant to corrosion, and have high strength-to-weight ratio, making them an ideal choice for constructing bridges that can withstand heavy loads and harsh environmental conditions.
Q: 45 and 316 which steel tubes are of high hardness?
This depends on the heat treatment state, if 45 steel, 314 stainless steel without heat treatment, 316 stainless steel hardness, if the heat treatment, that is 45 steel hardness.
