Introduction

Stainless steel seamless pipe is manufactured from a solid billet and machining the center and outside of the billet, to form a pipe to standard specifications.

Stainless steel pipe is primarily used in piping systems for the transport of fluids or gases. Stainless steel pipe resists oxidation, making it a low-maintenance solution that is suitable for high temperature and chemical applications. Because it is easily cleaned and sanitized, stainless steel pipe is also desired for applications involving food, beverages, and pharmaceutical applications.
