Introduction

At Roben Manufacturing, we’re committed to pushing the boundaries of engineering excellence, and our dedication to innovation shines through in our choice of materials for half-pipe coil jackets. While stainless steel alloys have long been favored for their corrosion resistance and durability, we believe that duplex alloys represent the next frontier in superior performance.

Strength and Durability

Duplex alloys offer a winning combination of strength and durability that surpasses traditional stainless-steel alloys. With a dual-phase microstructure consisting of austenitic and ferritic phases, duplex alloys exhibit higher tensile strength and resistance to stress corrosion cracking. This inherent strength enhances reliability and longevity, ensuring that our half-pipe coil jackets stand the test even in the most demanding applications

Corrosion Resistance

Corrosion is the arch-nemesis of industrial equipment, but duplex alloys are up to the challenge. Thanks to their balanced chromium, nickel, and molybdenum composition, duplex alloys resist various corrosive environments, including chloride-induced pitting and crevice corrosion. This exceptional corrosion resistance means that our half-pipe coil jackets maintain their integrity even in harsh operating conditions, minimizing downtime and maintenance costs for our customers.

Thermal Performance

In applications where heat transfer efficiency is paramount, duplex alloys shine. Their unique microstructure and composition enable them to withstand high temperatures without sacrificing mechanical properties, making them ideal for half-pipe coil jackets where thermal conductivity is crucial. Our duplex alloy jackets optimize process performance and energy efficiency by maximizing heat transfer efficiency, delivering tangible benefits to our customers’ bottom line.

Cost-Effectiveness

Despite their superior performance, duplex alloys offer compelling cost-effectiveness compared to alternative materials. Their excellent mechanical properties and corrosion resistance translate to reduced maintenance requirements and longer service intervals, resulting in lower total cost of ownership over the equipment’s lifecycle. At Roben Manufacturing, we understand the importance of delivering value to our customers, and our adoption of duplex alloys reflects our commitment to providing cost-effective solutions without compromising on quality or performance.
