What are Duplex heat exchanger tubes?

The duplex grade of stainless steel combines austenitic and ferrite alloys at almost equal proportions. This combination achieves material strength and excellent corrosion resistance. Duplex heat exchanger tubes facilitate the transfer of heat between fluids. They exhibit mechanical strength and resist cracking when exposed to high temperatures or harsh chemicals.

Silicon Steels, established in 1997, has supplied duplex heat exchanger tubes for over two decades. These components are integral to the pharmaceutical and chemical processing industries. Since these sectors are subject to abrasive agents, many other materials get damaged. Clients in the food sector, petrochemicals, and agriculture also rely on these tubes.

Superior quality duplex stainless steel finned tube heat exchanger manufacturer in India

As the term implies, a duplex stainless steel finned tube consists of fins on the outside (attached to the base). These fins enhance heat transfer (heating, cooling) mainly by upping the net surface area.

Finned tubes have several benefits, particularly for heat exchangers. The increased surface area for transfer reduces the number of exchangers required and cuts equipment and installation costs. Duplex material is a fine choice for these tubes due to its brilliant corrosion resistance and strength.

Silicon Steels is a prominent manufacturer of these tubes. The exemplary quality standards and customization options let you get the best components for your application.

Duplex steel u tube heat exchanger and UNS S31803 finned tube exporter in Mumbai

Many industries exposed to severe temperatures employ a duplex steel u tube heat exchanger for effective heat transfer. These tubes have flow baffles or sheets and facilitate a U-shaped bend. The duplex grade ensures these tubes can work even in temperatures up to 300 degrees Celsius. Another significant advantage of these tubes is their resistance to carbide precipitation.

UNS S31803 finned tubes get preferred in heat exchangers for their enhanced surface area. This material corresponds to stainless steel grade 2205. It also resists stress cracking even in chloride environments. These tubes get exported globally for use in chemical processing industries and pharmaceuticals.

Buy odd sized and custom shaped duplex steel u tubes and WNR 1.4462 seamless tubes in India

Silicon Steels can provide tubing of non-standard sizes, including odd-sized tubes and custom shapes. You can purchase products that adapt to the specific needs of your application while offering corrosion resistance and fitment for extreme environments. Duplex steel u tubes are especially popular for their U-shaped bend. It comes in handy in heat exchangers for efficient transfer between fluids.

WNR 1.4462 seamless tubes use a duplex grade of stainless steel with chromium, nickel, and molybdenum. They show tolerance to pitting and cracking and are perfect for chemical processing industries. The company sources raw materials from certified vendors and follows strict policies to ensure optimal product quality.

Stock and supply Duplex 2205 boiler tube with Full NDT examination

Duplex 2205 boiler tubes get coveted for their capability to tolerate high pressure and temperature. They comprise chromium and nickel and have 50% each of ferrite and austenite grades to obtain admirable thermal stability. These sturdy tubes are indispensable in heat exchangers, steam pipelines, and boilers.

Before acquiring them, however, it is essential to ascertain their quality and performance. An NDT examination (non-destructive testing) helps to confirm that the tube is defect-free and meets the desired properties. It includes tests like hydrostatics, Eddy Current, and ultrasonic. While eddy current tests detect transverse and longitudinal defects, ultrasonics and radiography can identify internal defects and wall thickness.
