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: What is the difference between nominal and actual pipe size?
- The nominal pipe size refers to the approximate size of a pipe based on its interior diameter, while the actual pipe size refers to the precise measurement of the interior diameter.
- Q: What is the difference between steel pipe and fiberglass pipe?
- Steel pipe and fiberglass pipe differ in terms of material composition, durability, flexibility, and cost. Steel pipe is made of steel, which provides strength and resilience, making it ideal for high-pressure applications and underground installations. Fiberglass pipe, on the other hand, is composed of reinforced plastic fibers, resulting in a lightweight and corrosion-resistant material suitable for above-ground and corrosive environments. While steel pipe offers higher tensile strength, fiberglass pipe excels in its flexibility, allowing for easier installation and reduced maintenance. Additionally, steel pipe is typically more expensive due to the cost of materials and manufacturing processes, while fiberglass pipe is more cost-effective in terms of initial installation and long-term maintenance.
- Q: What are the common fittings and accessories used with steel pipes?
- Some common fittings and accessories used with steel pipes include couplings, elbows, tees, reducers, flanges, and valves. Additionally, accessories such as pipe hangers, brackets, clamps, and gaskets are often used to support and secure the pipes.
- Q: Can steel pipes be used for underground electrical conduits?
- Yes, steel pipes can be used for underground electrical conduits.
- Q: How are steel pipes used in stadium construction?
- Steel pipes are commonly used in stadium construction for various purposes such as structural support, plumbing systems, and the installation of lighting and audio equipment. They provide strength, durability, and versatility, making them ideal for ensuring the overall stability and functionality of the stadium.
- Q: Are steel pipes suitable for underground installations in areas with high moisture content?
- Yes, steel pipes are suitable for underground installations in areas with high moisture content. Steel pipes are known for their durability and resistance to corrosion, which makes them ideal for withstanding moisture and underground conditions. Additionally, steel pipes can be coated or lined with protective materials to further enhance their resistance to moisture, ensuring their long-term performance and reliability in such environments.
- Q: Can steel pipes be used for underground steam pipelines?
- Indeed, underground steam pipelines can indeed utilize steel pipes. Given their robust and enduring characteristics, steel pipes are frequently employed for an assortment of pipelines, such as those carrying steam. Their capacity to endure elevated temperatures and pressures renders them suitable for the subterranean transportation of steam. Furthermore, steel pipes exhibit outstanding resistance to corrosion, a crucial feature for subterranean pipelines that encounter moisture and potentially corrosive substances in the soil. In summary, steel pipes represent a dependable and widely embraced option for underground steam pipelines.
- Q: How are steel pipes classified based on pressure ratings?
- Steel pipes are classified based on pressure ratings into different categories such as schedule numbers or pressure classes, which indicate their ability to withstand different levels of pressure.
- Q: Are steel pipes resistant to fire?
- Yes, steel pipes are generally highly resistant to fire due to their inherent fire-resistant properties.
- Q: How are steel pipes used in construction?
- Steel pipes are commonly used in construction for various purposes such as structural supports, plumbing systems, and underground utility installations. They provide strength, durability, and resistance to corrosion, making them ideal for carrying fluids, gases, and other materials.
