Rolled and Welded Steel Pipe Types Based On Shape
When it comes to rolled and welded steel pipes, shape is a fundamental characteristic that determines their suitability for specific applications. The most common shapes include:
1.Circular Pipes: These are the most widely used type of rolled and welded steel pipes. Their cylindrical shape makes them ideal for transporting fluids and gases, as well as for structural applications. Circular pipes offer excellent strength-to-weight ratios and are easy to join using various welding techniques.
2.Square Pipes: As the name suggests, these pipes have a square cross-section. They are often used in construction and architectural projects due to their clean, modern appearance and ability to provide strong support. Square pipes are particularly popular in furniture design and as structural elements in buildings.
3.Rectangular Pipes: Similar to square pipes, rectangular pipes have a rectangular cross-section. They offer a balance between strength and aesthetics, making them suitable for both structural and decorative applications. Rectangular pipes are commonly used in handrails, fencing, and industrial equipment frames.
4.Oval Pipes: These pipes have an elliptical cross-section, combining some of the benefits of both circular and rectangular pipes. Oval pipes are often used in specialized applications where aerodynamics or space constraints are important factors.
The choice of form frequently relies on the specific requirements of the undertaking, as each shape provides perks of its very own. In construction initiatives, for instance, square and square pipes provide easier-to-work-with surfaces that are flat, but round pipes are excellent for fluid transmission.
Based On Size
Size is another crucial factor in categorizing rolled and welded steel pipes. The size of a pipe is typically defined by its outer diameter (OD) and wall thickness. Here are some common size categories:
1.Small Diameter Pipes: These pipes typically have an outer diameter of less than 2 inches (50.8 mm). They are commonly used in residential plumbing, HVAC systems, and small-scale industrial applications. Small diameter pipes are often easier to handle and install, making them popular for projects with space constraints.
2.Medium Diameter Pipes: Pipes with outer diameters ranging from 2 inches to 12 inches (50.8 mm to 304.8 mm) fall into this category. These pipes are versatile and find applications in various industries, including construction, oil and gas, and water treatment facilities. Medium diameter pipes offer a good balance between flow capacity and structural strength.
3.Large Diameter Pipes: Any pipe with an outer diameter exceeding 12 inches (304.8 mm) is considered a large diameter pipe. These pipes are crucial for major infrastructure projects, such as long-distance oil and gas pipelines, water mains, and large-scale industrial processes. Large diameter pipes can handle high flow rates and pressures, making them essential for demanding applications.
4.Custom Sizes: In addition to standard sizes, many manufacturers offer custom-sized rolled and welded steel pipes to meet specific project requirements. This flexibility allows engineers and designers to optimize their systems for maximum efficiency and performance.
A rolled and welded iron pipe's correct dimension ought to be selected after taking consideration of its flow rate, necessary stress, and architectural strains. It is essential that you get guidance from experts or look up industry norms such as API 5L, ASTM A53, or ASTM A500 to ensure that the pipe size you picked satisfies the specifications for the task at hand.
Based On Manufacturing Process
The manufacturing process significantly influences the properties and performance of rolled and welded steel pipes. Here are the main types based on how they are produced:
1.Electric Resistance Welded (ERW) Pipes: ERW pipes are manufactured by rolling flat steel sheets into a cylindrical shape and welding the seam using electric current. This process creates a strong, continuous weld along the length of the pipe. ERW pipes are known for their uniform wall thickness and are commonly used in applications such as water lines, structural supports, and light-duty oil and gas transportation.
2.Double Submerged Arc Welded (DSAW) Pipes: DSAW pipes are produced by welding both the inside and outside of the pipe seam using a submerged arc welding process. This results in a very strong and reliable weld, making DSAW pipes suitable for high-pressure applications and large-diameter pipelines. They are often used in the oil and gas industry for long-distance transportation of hydrocarbons.
3.Spiral Welded Pipes: These pipes are manufactured by helically winding a continuous steel strip and welding the spiral seam. Spiral welded pipes can be produced in large diameters and are often more cost-effective than longitudinally welded pipes of similar size. They are commonly used in water transmission, piling, and structural applications.
4.Cold-Formed Welded Pipes: This process involves forming the pipe at room temperature and welding the seam. Cold-formed welded pipes are known for their precise dimensional control and smooth surface finish. They are often used in applications requiring tight tolerances, such as automotive components and precision machinery.
