High-Frequency Welded (HFW) pipes are manufactured with external diameters ranging from 114.3 mm to 323.9 mm and wall thicknesses up to 12.7 mm. The possible lengths of a single pipe section range from 6 m to 18 m. The pipes undergo leak testing, as well as non-destructive testing using ultrasonic or eddy current methods.

These pipes are intended for use in district heating, gas distribution, the petrochemical industry, and structural applications. They are also suitable for use as casing and drilling pipes in infrastructure projects related to transportation.
