Information
Features
Seamless Carbon Rectangular Steel Pipes are a popular choice for many industrial applications due to their strength, durability, and versatility. Here are some of the key features of these pipes:
- High Strength: These pipes are known for their high tensile strength, making them highly durable and capable of withstanding substantial pressure.
- Seamless Construction: Seamless pipes are manufactured from a single piece of metal without any seams. This results in uniform strength throughout the structure and high resistance to pressure.

Technology
Manufacturing seamless carbon rectangular steel pipes is a complex and meticulous process. This involves transitioning from a cylindrical seamless pipe to a rectangular shape, while maintaining the seamless structure. Here is a general overview:
- Billet Preparation: The process starts with a round, solid billet of carbon steel. The billet is heated to a high temperature, making it pliable.
- Piercing: The heated billet is then pierced through its center with a mandrel to form a hollow tube.
- Elongation and Sizing: The hollow tube is then elongated and rolled through a series of dies and mandrels, which progressively reduce its diameter and wall thickness while increasing its length. The tube is then passed through a sizing mill, which further refines the outside diameter and wall thickness to precise specifications.
- Heat Treatment: The pipe then undergoes a heat treatment process, such as normalizing or annealing, to relieve the stresses from the previous forming steps and to refine the steel’s microstructure, thereby enhancing its mechanical properties.
- Cold Drawing: For more precise dimensions and better surface finish, some seamless pipes may undergo additional cold drawing steps.
- Rectangular Shaping: The formed circular seamless pipe is then passed through a series of roller dies that gradually form the pipe into a rectangular shape. This is a complex process that requires precise control to avoid deformation while maintaining a seamless structure.
- Cutting: The formed rectangular pipe is then cut into the required lengths.
- Inspection: Each pipe undergoes a thorough inspection for quality control, which may include visual inspection, dimensional checks, and non-destructive testing to ensure there are no defects in the pipe.
- Finishing: The pipes may then be treated or coated as per the requirements.
- Packing and Shipping: Finally, the pipes are bundled and packed for shipping.

Application
Seamless carbon rectangular steel pipes are formed without a welded seam, making them stronger and better suited for carrying fluids than welded pipes. This quality leads to a wide range of applications:
- Oil and Gas Industry: Seamless pipes are predominantly used in the oil and gas industry for the transportation of fluids and gases under high pressures and temperatures. They are utilized in drilling and conveyance of combustible gases and liquids.
- Chemical Industry: In the chemical industry, these pipes are used to carry corrosive fluids and steam under high pressure and temperature conditions. They can be designed to meet specific strength and chemical resistance requirements.
- Automotive Industry: In this industry, seamless pipes are commonly used in the manufacture of parts that need to withstand high pressures, such as fuel injection systems. They’re also used in manufacturing components of vehicles like axles.
- Power Generation: Seamless pipes play a critical role in power plants, especially in high-pressure boiler applications, where they are used to carry steam and other high-pressure and high-temperature fluids.
- Mechanical Engineering: These pipes are used for structural applications, such as in machinery parts, hydraulic cylinders, and other components where strength and precision are required.
- Shipbuilding: In shipbuilding, seamless pipes are used for the fabrication of pipelines and for installation of high-pressure steam systems.
- Aerospace: Seamless pipes are used in the manufacture of high-pressure and temperature-resistant devices in the aerospace industry.
Package
Packaging for carbon steel rectangular pipes usually depends on the length, quantity, and the requirements of the customer. The main goal of packaging is to protect the product during storage and transportation, ensuring it reaches the customer in the best possible condition.
- Bundling: The most common method for packaging is bundling, where multiple steel pipes are bound together using steel straps. Depending on the length and size of the pipes, the number in each bundle can vary.
- Wrapping: After bundling, the steel pipes can be wrapped in a plastic or waterproof paper to protect against rust and other environmental damage. This is particularly important for carbon steel, which can corrode easily if not properly protected.
- Crating: For especially large or heavy pipes, or for long-distance shipping, wooden or steel crates can be used to provide additional protection. Crating can prevent damage during loading, unloading, and transportation.
- End Protection: Caps can be placed on the ends of the pipes to protect them from damage and to prevent foreign objects from entering the pipe. This is especially important for threaded or beveled ends, which can be more susceptible to damage.
- Marking: Each bundle or crate is typically marked with identifying information, such as the size, grade, heat number, manufacturer’s name or logo, and any other information required by the customer or by shipping regulations.
