ABOUT SSAW PIPE

Spiral Submerged Arc Welded pipes (SSAW pipes) are manufactured by helically forming steel strips or plates into a tubular shape and then welding along the spiral seam using submerged arc welding technology. The spiral weld seam of SSAW pipes undergoes additional non-destructive testing and stress relieving treatment to ensure uniform strength distribution throughout the pipe body. Due to their unique spiral forming process, SSAW pipes offer exceptional flexibility in diameter dimensions and are particularly suitable for large-diameter applications with varying size requirements. SSAW pipes can be manufactured from various materials, including carbon steel, stainless steel, and alloy steel, allowing selection based on specific project specifications and environmental conditions. Surface treatments such as hot-dip galvanizing and 3PE anti-corrosion coating can be applied to enhance durability and extend service life in harsh operating environments. With their excellent mechanical properties, SSAW pipes are widely used in water transmission projects, piling foundations, bridge construction, and other infrastructure applications.

WELDED STEEL PIPE

MATERIAL OF SSAW PIPE

  • CARBON STEEL
  • STAINLESS STEEL
  • ALLOY STEEL

Carbon steel spiral submerged arc welded pipes are primarily composed of iron-carbon alloys and do not contain other alloying elements. Based on carbon content, they can be classified into low-carbon steel, medium-carbon steel, and high-carbon steel. As carbon content increases, strength and hardness improve, but ductility and weldability decrease. Carbon steel Spiral submerged arc welded pipes offer excellent strength and toughness, capable of withstanding high pressure loads. They also exhibit good machinability and weldability, making them widely applicable. The disadvantage of carbon steel is its relatively poor corrosion resistance, making it susceptible to oxidation and corrosion in humid or extreme environments. Therefore, in certain extreme operating conditions, secondary treatments such as epoxy coating or hot-dip galvanizing are typically required to enhance durability. Due to its relatively low cost and reliable performance, carbon steel spiral submerged arc welded pipes are extensively used in industries such as construction, machinery manufacturing, and oil and gas transportation.

Stainless steel spiral submerged arc welded pipes are primarily made from carbon steel with the addition of chromium alloy elements to enhance their corrosion resistance and high-temperature resistance. The higher the chromium content, the stronger the corrosion resistance. This material has a smooth surface and excellent oxidation resistance, capable of withstanding corrosion from various chemical substances. It performs exceptionally well in extreme environments such as humid or corrosive soils, making it suitable for a wide range of high-demand applications, including chemical processing, food processing, pharmaceuticals, and marine engineering. It is particularly important in medical devices and the food industry. Although stainless steel Spiral submerged arc welded pipes have relatively high costs, their high durability and low maintenance costs make them an ideal choice for many specialized applications.

Alloy steel spiral submerged arc welded pipes are manufactured by adding other alloy elements (such as chromium, nickel, molybdenum, tungsten, etc.) to an iron-carbon alloy base. Stainless steel is also a type of alloy steel. The primary characteristics of this material are its excellent strength, toughness, and wear resistance, enabling it to perform exceptionally well under high-temperature, high-pressure, corrosive, and extreme environmental conditions. Alloy steel Spiral submerged arc welded pipes are designed to meet specific application requirements and are commonly used in industries such as petroleum, natural gas, chemicals, aerospace, and nuclear energy. Alloy steel Spiral submerged arc welded pipes offer higher safety and reliability. Due to their unique composition and production process, alloy steel spiral submerged arc welded pipes typically have higher costs. However, their long-term durability and performance advantages make them an indispensable material in many high-end applications.

LSAW PIPE VS SSAW PIPE

LSAW pipe and SSAW pipe are both manufactured using the SAW (Submerged Arc Welding) process. However, their manufacturing methods and processes differ. LSAW pipe employs a longitudinal welding process, made from a single sheet of steel plate, offering higher strength and pressure-bearing capacity. SSAW pipe utilizes a spiral welding process, typically formed from steel coils, with a spiral-shaped weld seam. SSAW pipes have relatively lower production costs and are suitable for manufacturing large-diameter pipelines. However, due to their longer weld seams, they exhibit relatively lower precision and pressure-bearing capacity.
