Duplex Steel Chemical Tank Manufacturer

A Duplex steel chemical tank is a storage container made using high-quality duplex stainless steel. This metal combines two kinds of stainless steel, such as ferritic and austenitic. Astech Tube is a leading Duplex steel chemical storage tank manufacturer known for delivering high-quality tanks. These tanks are often used in places where corrosion is a big concern. We specialize in crafting chemical storage solutions that last longer and perform better under pressure. Each tank goes through careful cutting, forming, welding, and finishing steps. We also use advanced tools to measure ferrite levels and ensure the right structure in every weld.

These tanks are known for their high resistance, excellent strength under pressure, and strong performance in chloride-rich environments. They are stronger than regular stainless steel tanks and provide better resistance to stress corrosion cracking and pitting, especially in high-temperature or salty conditions. Due to their superior strength, tanks can be constructed with thinner walls without compromising durability. They also have low thermal expansion and high thermal conductivity so they can be used safely in fluctuating temperatures. Our High-Quality Duplex Steel Chemical Tank are suitable for various kind of application, from chemical processing to fertilizer storage, water and wastewater treatment, oil and gas refining, marine and offshore systems, pulp and paper mills, as well as food, beverage, and pharmaceutical production, where sanitation and corrosion resistance are paramount.

Our tanks meet ASTM A240, A276, and A789 standards. Whether you need 100 liters, or several thousand, we’ve got you covered. The wall thickness can range from 2 mm to 20 mm, depending on what you’re storing and at what pressure. Finishes include mill finish, pickled and passivated, or electro-polished. You can get welded or seamless tanks in vertical or horizontal formats. These tanks have high thermal conductivity and excellent resistance to chloride stress, with a typical density of around 7.8 g/cm³.

Every duplex steel chemical tanker goes through ferrite content checks to make sure the welds have the right mix for strength and resistance. We also test for corrosion using salt spray and immersion methods. Mechanical strength tests like tensile, impact, and hardness checks make sure the tank can work well in a harsh environment. Each tank is carefully packed in wooden crates or wrapped in waterproof materials for safe shipping. Looking for a high-performance Duplex Steel Chemical Tank that’s built to last?
