Titanium Welded Tube ，titanium Tube，titanium Pipe,titanium Square Tube

1. Introduction

Welded pipe production technology is simple, high production efficiency, varieties and specifications, equipment investment is less. The strength of spiral welded pipe is generally higher than that of longitudinal welded pipe. The welded pipe with larger diameter can be produced with narrower billet, and the welded pipe with different diameters can be produced with the same width of billet. The general strength is lower than seamless titanium pipe.
