Nestled in the heart of Naypyidaw, Tun Pipes stands as a trusted name for industrial solutions, proudly manufacturing and supplying superior Copper Nickel 7030 Pipes. We understand that your projects demand materials built to withstand the most demanding conditions, which is why our products are engineered with precision and a deep commitment to quality. For clients across Myanmar and beyond, we offer not just pipes, but a promise of durability and reliability for critical applications where failure is not an option.
These Copper Nickel 70/30 Pipes are made up of about 70% copper and 30% nickel, often with trace amounts of iron and manganese to boost strength and corrosion resistance. They showcase impressive mechanical properties, such as high tensile strength, excellent ductility, and remarkable resistance to seawater and chemical erosion. They remain stable across a wide range of temperatures and pressures, making them dependable in tough conditions. The blend of copper and nickel provides both strength and flexibility, enabling the pipes to endure mechanical stress while resisting fouling, pitting, and crevice corrosion in both marine and industrial settings.
