Description

Technical Field

[0002] Steel pipes play an important role in the fields of construction due to their high strength, corrosion resistance, and strong pressure bearing capacity. Although in many large-scale projects, steel pipes are customized to specific lengths according to project needs for easy installation or use, in building or pipeline construction projects, non-customized length steel pipes are often used, which requires on-site measurement of the length of the steel pipe or cutting of the steel pipe to a fixed length.
