Welded Steel Tubing製品情報

Overview

Welded steel tubing is single-wall tubing that is created by forming copper-coated steel strips into a single-layer tubular shape and then welding the surfaces together using electric resistance welding technology.

This tubing has exceptional airtightness. In addition, the internal cleanliness is excellent, the inner weld bead* is extremely small, and the inner and outer surfaces are smooth and even. By using a specialized annealing process, the metallographic structure of the weld seam is completely unchanged from that of the original material.

* A bead is a protuberant material deposit that can form during the welding process.
