Product Introduction

Hastelloy lap flanges are unique in that they consist of two parts, the flange itself and the bell end. The back side has a slightly square cut shoulder at the center or pipe hole. The front side has a flat surface with a threaded hole in the center that mates with the threaded back side of the end cap. This is where the end of the short pipe will wrap tightly around the center hole of the flange.

Benefits of Hastelloy Lapped Joint Flanges:

Since a lapped joint flange has a two-piece configuration, it offers a way to reduce costs when piping systems demand it. For high-cost alloys, the only "wetted" part is the stub end. In this situation, it suffices that the stub end consists of the higher cost corrosion-resistant material, where the flange itself can be produced from lower-cost steel.
