The spiral tube, also known as helical tube or spiral steel pipe

The spiral tube, also known as helical tube or spiral steel pipe, is a type of piping characterized by its spiral weld seam. It is typically manufactured through a spiral welding process, where steel plates or strips are coiled into a spiral shape and then connected through high-frequency welding or double-wire submerged arc welding to form a continuous spiral weld seam.

INSPECTION STANDARD

 

The detection standards for spiral tubes ensure their quality and safety for use in various applications. Some of the main standards include:

 

Dimensional Accuracy: The dimensions of the spiral tube, such as its outer diameter, wall thickness, and length, should meet specified requirements.

 

Material Composition: The chemical composition of the steel used in the spiral tube should be within specified limits to ensure its mechanical properties and corrosion resistance.

 

Weld Quality: The weld seams should be inspected for defects such as cracks, porosity, and inclusions. Non-destructive testing methods, such as ultrasonic testing and radiography, are commonly used for this purpose.

 

Corrosion Resistance: If the spiral tube is coated with a corrosion-resistant material, the coating should be inspected for adherence, thickness, and uniformity.

 

Pressure Testing: The spiral tube should be subjected to pressure testing to ensure its ability to withstand the intended operating pressure without leakage or failure.

 

In conclusion, spiral tubes are versatile and reliable piping solutions with a wide range of applications. Their advantages, trends, and prospects make them an attractive option for various industries. However, it is important to adhere to strict detection standards to ensure their quality and safety for use.
