Advantages of Spiral Welded Pipe
Increased productivity: Spiral welded pipe is produced by continuously welding spirals from strip material. The advantages of the process are increased productivity and lower costs. The spiral welded pipe process is continuous, meaning that longer pipe lengths can be produced than with other methods.
Improved quality: Spiral welded pipe also has improved quality due to the continuous nature of the welding process. This allows for better control of the weld bead, resulting in a stronger and more consistent weld.
Greater flexibility: The spiral welded pipe process also provides greater design and material choice flexibility. The process can accommodate many materials, including carbon steel, stainless steel, and aluminium. The spiral welding process can also produce pipes with various diameters and wall thicknesses.
Increased strength: Spiral welded pipe also has increased strength due to the continuous nature of the welding process. The welding process’s lack of starts and stops results in a stronger overall bond between the metal layers. The spiral welding process also creates less stress on the material, further increasing its strength.
Greater versatility: The spiral welded pipe process is also versatile enough for various applications. Spiral welded pipes can be used for everything from transportation pipelines to structural applications such as buildings and bridges. Additionally, the spiral welded pipe can be customized to meet the specific needs of each application.

Application of Spiral Welded Pipe
Structural support
Due to its high strength and durability, spiral welded pipe is commonly used to build various support structures such as bridges, motorway guardrails and building architecture.
Piping systems
Due to its good pressure-bearing capacity and sealing, spiral welded pipes are commonly used in piping systems for transporting water, natural gas and other low-pressure fluids.
Construction applications
In the construction sector, spiral welded pipes are used for support and structural stability, for example as the main support structure in the construction of high-rise buildings or large public facilities.
Agricultural irrigation
Due to their ability to withstand certain pressures, spiral welded pipes are also commonly used in the construction of agricultural irrigation systems to ensure the efficient transport of water.
Industrial applications
In the manufacturing and processing industries, spiral welded pipes are used to support machinery and equipment, as well as being used as transmission pipes in various processes.
Processing Process of Spiral Welded Pipe
The raw materials are strip steel coils, welding wire, and flux. Strict physical and chemical tests are required before investment.The strip head and tail are connected by single wire or double wire submerged arc welding, and automatic submerged arc welding is used for repair welding after coiling into steel pipe.
Before forming, the strip undergoes leveling, edge trimming, edge planing, surface cleaning and conveying, and pre-bending treatment. The electric contact pressure gauge is used to control the pressure of the cylinders on both sides of the conveyor to ensure the smooth transportation of the strip. Adopt external control or internal control roll forming.
The welding seam gap control device is adopted to ensure that the welding seam gap meets the welding requirements, and the pipe diameter, the amount of misalignment and the welding seam gap are all strictly controlled. Both internal welding and external welding adopt American Lincoln electric welding machine for single-wire or double-wire submerged arc welding to obtain stable welding specifications.
The welded seams after welding are inspected by an online continuous ultrasonic automatic flaw instrument, which guarantees 100% non-destructive testing coverage of spiral welds. If there is a defect, it will automatically alarm and spray the mark, and the production workers can adjust the process parameters at any time to eliminate the defect in time. Use an air plasma cutting machine to cut the steel pipe into individual pieces.
In order to ensure the quality and reliability of spiral welded pipes, manufacturers adhere to strict testing and inspection procedures. Key tests performed include hydrostatic testing, non-destructive testing (such as ultrasonic or radiographic inspection) and mechanical testing (tensile, yield and impact testing). These tests ensure that pipes meet required strength, size and leakage standards.
Spiral welded pipes can be produced in various diameters and lengths, making them highly adaptable to different project requirements. This flexibility ensures that the pipes can be customized to meet specific needs, providing tailored solutions for diverse industrial applications.
