Straight seam steel pipes, also known as straight seam welded pipes, are a type of welded steel pipe. They have a wide range of applications in daily life. Because of this wide range of applications, there are many specifications available for straight seam steel pipes.
So, do you know what specifications straight seam steel pipes are available in? Straight seam steel pipes are made by bending steel plates or steel chains and then welding the joints. In terms of welding classification, welded pipes are mainly divided into two types: straight seam steel pipes and spiral welded pipes. Compared to spiral welded pipes, straight seam welded pipes have many advantages and are increasingly widely used in daily life. These applications mainly include: galvanized rectangular pipes, oxygen pipes, wire sheaths, measuring pipes and coiled pipes, deep well pipelines, automotive pipes, and transformer pipes.
Ordinary welded pipes: During use, the main function of ordinary welded pipes is to transport fluids. The material used to manufacture these welded pipes is usually easy-to-weld low-carbon steel. The pipes should conform to the specifications for both standard and thickened steel pipes. Nominal pressure pipes are mainly used for pressure, bending, and other tests in practical applications. Therefore, engineering pressure pipelines have certain specifications for process design performance during production. Typically, the supply length from enterprises is 4-10m, which is not fixed. When preparing welded pipes of different specifications, the welded pipe company should ensure the same thickness. With the development and progress of science and technology, the processing technology of welded pipes is becoming increasingly advanced. At this stage, straight seam steel pipes have replaced some stainless steel pipes, and the thickness of welded pipes has reached approximately 219 mm (8 feet).
Metric/Imperial Welded Pipes: Specifications and models are the same as those for stainless steel pipes. They are made from ordinary carbon steel, high-quality carbon steel, or ordinary low-energy alloy steel, serving as the basis for cold and hot rolled strip electric welding or hot rolled strip electric welding technology. Metric/Imperial welded pipes are divided into general-purpose steel pipes and thin-walled steel pipes. They are commonly used for constructing prefabricated parts, such as automotive drive shafts, or for conveying fluids. Thin-walled steel pipes are used in the manufacture of furniture, lighting equipment, etc. Ensure the compressive strength and tensile strength of seamless welded steel pipes.
Idler Roller Steel Pipes: Welded steel pipes used for rollers in belt conveyors, typically undergoing pressure and deformation tests.
Spiral welded steel pipe: Carbon steel is rolled into a pipe according to ordinary structural steel or low-angle spiral configuration alloy (called forming angle), and then welded to form a large-diameter steel pipe. Spiral welded pipe is often used in petrochemical gas transmission projects. Spiral welded steel pipe has single-sided positive and negative electrodes. The welded steel pipe should ensure that the hydrostatic test, compressive strength, and tensile properties meet the requirements.
