Product Introduction

Hastelloy C276 flange is a low-cost flange that is a popular choice in the pipeline industry. These flanges slide easily into the pipe and are secured in place by welding. Hastelloy C276 blind flanges have no hub and a drilled center. In many piping systems, these flanges are used to stop flow. They can also be used to clean the pipe if the pipe is secured. High-pressure systems often use Hastelloy C276 welded flanges. These flanges feature a long protruding neck that provides support for the pipe when pressure or temperature increases.
