With a reputation for precision engineering and rigorous quality standards, the company produces coil tubing that excels in demanding industrial settings. Tun Pipes caters to a variety of industries, including oil and gas, chemical processing, petrochemical, marine, and power generation. Their Super Duplex Steel Coil Tubing is highly regarded for its remarkable blend of high strength, corrosion resistance, and flexibility, making it perfect for applications that require long-lasting reliability, structural integrity, and ease of installation in tight or complex environments.
The Super Duplex Steel Coil Tubing, like grade S32750, consists of about 25% chromium, 7% nickel, 4% molybdenum, and 0.3% nitrogen. This unique alloy boasts impressive mechanical properties, featuring a tensile strength ranging from 830 to 1000 MPa, yield strength between 550 and 750 MPa, and an elongation of roughly 25%. Its exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking—especially in chloride-rich and acidic conditions—ensures its durability. The coiled design provides flexibility for straightforward installation while maintaining consistent strength and corrosion resistance, making it ideal for critical process systems and heat exchangers.
