Alloy pipe is a steel pipe according to the production materials (i.e. material) to define, just as its name implies is made of alloy steel seamless pipe; and is in accordance with the production process (seamed seamless) to define, seamed pipe seamless pipe is different from, including straight seam welded pipe and spiral tube.
Manufacturing process
1 hot-rolled (extrusion seamless pipe): billet, heating, perforation, three roll cross rolling, rolling or extrusion, tube off, sizing pipe (or reducing), cooling, straightening, water pressure test (or testing), marking, storage
2 cold drawing (rolling) seamless steel pipe: billet, heating, perforation, heading, annealing, pickling, oiling round tube (copper) and multi pass drawing (Leng Zha), the blank pipe, heat treatment, straightening, water pressure test (testing), marking, storage
[(diameter - thickness) * wall thickness of]*0.02466=kg/ meters (per metre weight)
Alloy pipe use
Alloy pipe for low and medium pressure boiler (work pressure is generally not more than 5.88Mpa, the operating temperature at 450 DEG C) of the heating surface tube; used for high pressure boiler (work pressure is generally above 9.8Mpa, operate at a temperature of 450 DEG to 650 DEG C between) the heating surface tubes, economizer, superheater, reheater, petrochemical industry uses the tube and so on.
- Q:How are steel pipes cleaned and flushed?
- Steel pipes can be cleaned and flushed using various methods depending on the specific requirements and conditions. One common method is mechanical cleaning, which involves the use of wire brushes, scrapers, or other abrasive tools to physically remove any debris, rust, or scale from the inner surface of the pipes. This method is effective for removing loose or easily detachable contaminants. Chemical cleaning is another widely used method, especially for pipes with more stubborn deposits or rust. Various chemicals or cleaning agents are flushed through the pipes to dissolve or loosen the buildup, which can then be washed away. Acid-based solutions are commonly used for this purpose, but it is important to choose the appropriate chemical and concentration to avoid damaging the pipes. High-pressure water jetting is another effective method for cleaning and flushing steel pipes. Water is pumped at high pressure through a nozzle, creating a powerful jet that can dislodge and remove any debris or deposits from the pipe walls. This method is particularly useful for removing hard or compacted materials that cannot be easily removed by other means. In some cases, a combination of these methods may be required to achieve the desired cleanliness. For instance, a pre-cleaning with mechanical tools can be followed by chemical cleaning or high-pressure water jetting to ensure thorough flushing and removal of contaminants. Regular maintenance and cleaning of steel pipes are essential to maintain their efficiency and prevent corrosion. It is important to follow proper procedures and safety guidelines when cleaning and flushing steel pipes to ensure effective results and avoid any damage to the pipes.
- Q:Seamless steel pipe and welded pipe what is the difference?
- The welded pipe is made directly from the stainless steel band by machine, and it is made of round steel or perforated by Guan Pi
- Q:What is the difference between black and galvanized steel pipes?
- The main difference between black and galvanized steel pipes lies in their coating. Black steel pipes are untreated and have a dark, uncoated appearance, while galvanized steel pipes are coated with a layer of zinc to prevent corrosion. This zinc coating on galvanized pipes helps protect against rust and extends their lifespan, making them suitable for outdoor and exposed applications. Black steel pipes, on the other hand, are typically used for indoor applications and are often painted or coated after installation to prevent rusting.
- Q:What is the average lifespan of steel pipes in different applications?
- The average lifespan of steel pipes in different applications can vary significantly depending on factors such as the type of application, the environment it is exposed to, and the level of maintenance. However, in general, steel pipes can last anywhere from 20 to 100 years or more, making them a durable and reliable choice for various industries and infrastructure projects.
- Q:Are steel pipes suitable for industrial cooling systems?
- Yes, steel pipes are generally suitable for industrial cooling systems. Steel is a strong and durable material that can withstand high pressure and temperature fluctuations commonly found in cooling systems. It has excellent resistance to corrosion, making it ideal for use with water or other coolants. Additionally, steel pipes have good thermal conductivity, allowing for efficient heat transfer in the cooling process. They are also readily available and cost-effective, making them a popular choice in industrial applications.
- Q:How are steel pipes used in the mining industry?
- Steel pipes are widely used in the mining industry for various purposes such as transporting water, slurry, and other fluids, as well as for ventilation and structural support in underground mines. Their durability, resistance to corrosion, and high pressure capacity make them ideal for these applications.
- Q:What are the different types of steel pipe fittings?
- There are several types of steel pipe fittings, including elbows, tees, couplings, unions, reducers, caps, plugs, and crosses.
- Q:What is the lifespan of galvanized steel pipes?
- The lifespan of galvanized steel pipes can vary depending on various factors such as the environment, usage, and maintenance. However, on average, galvanized steel pipes can last between 40 to 70 years.
- Q:What are the common uses of stainless steel pipes?
- Stainless steel pipes are commonly used in various industries and applications such as plumbing, construction, oil and gas, food processing, pharmaceuticals, and automotive. They are valued for their durability, corrosion resistance, and ability to withstand high temperatures. Stainless steel pipes are utilized for transporting fluids, gases, and chemicals, as well as for structural purposes in buildings and infrastructure.
- Q:Are steel pipes suitable for wastewater treatment plants?
- Yes, steel pipes are suitable for wastewater treatment plants. Steel pipes are known for their durability, corrosion resistance, and high strength, making them ideal for handling the demanding conditions of wastewater treatment plants. They can effectively transport and contain wastewater without any structural or functional issues, ensuring efficient and reliable operation of the treatment process.
