Product Overview

Application and service highlights

Introduction

Lined flexible hose pipes are selected where movement, vibration or connection offset makes rigid piping impractical in corrosive chemical duty. They are often used between mobile equipment, pumps and fixed lines to provide flexibility while maintaining media compatibility.

Key Features

Allows movement compensation between connected equipment points.
Useful in areas with vibration, misalignment or frequent maintenance access.
Combines flexibility with a corrosion resistant internal flow surface.
