Astech Tube is a prominent Super duplex steel storage tank manufacturer in India that meets international standards. Super duplex steel storage tanks are known for their strength, durability, and resistance to corrosion. Constructed using high-quality material, the tanks are used to store liquids of all kinds, including hazardous and corrosive chemicals. They are a top choice for industries that demand long-lasting and reliable storage solutions. With a commitment to quality and precision, our tanks are crafted to withstand harsh conditions and maintain performance over time.
They have very high resistance to pitting and crevice corrosion, and hence are ideal for handling harsh chemicals. The increased mechanical strength and toughness enable these tanks to resist high pressure and harsh temperatures. Due to a long lifespan, low maintenance requirements, our Super duplex steel industrial storage tanks are designed to perform reliably over time. The welding characteristics further contribute to the tank's structural integrity, and hence it makes a suitable choice for demanding application.
