Tun Pipes, located in Naypyidaw, Myanmar, stands out as a top manufacturer and supplier of premium Super Duplex Steel Tubing. With a reputation for precision engineering and strict quality control, the company produces tubing that excels in tough industrial settings. Tun Pipes caters to a variety of sectors, including oil and gas, chemical processing, petrochemical, marine, and power generation. Their Super Duplex Steel Tubing is highly regarded for its remarkable blend of high strength, excellent corrosion resistance, and durability, making it perfect for applications that demand long-lasting reliability, structural integrity, and performance in harsh and aggressive environments.
When it comes to Super Duplex Steel Tubing, grade S32750 is a prime example, containing about 25% chromium, 7% nickel, 4% molybdenum, and 0.3% nitrogen. This unique alloy boasts impressive mechanical properties, such as a tensile strength ranging from 830 to 1000 MPa, yield strength between 550 and 750 MPa, and an elongation of around 25%. It also offers outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in environments rich in chlorides and acids. The high strength-to-weight ratio, toughness, and durability of Super Duplex Steel Tubing make it an excellent choice for critical applications where both strength and corrosion resistance are vital.
