Pathan Durgadevi Udyan, Ground Floor, 25 Plot No 74/80, Patra Chawl, Maruti , Mandir Marg, Second Street, Girgaon, Mumbai, Maharashtra 400004At Tubotech, exquisite meets high performance as we are a reputed Cu 70/30 Instrument Fittings manufacturer, supplier, and exporter, presenting precision-engineered solutions to meet the vital demands of international industries. With reliability and a cutting-edge production setup, we focus our attention on producing Cu-Ni 70/30 Instrument Fittings that deliver remarkable corrosion resistance and mechanical power in the most challenging environments.
We recognize that reliability and overall performance are paramount. That’s why our Cu 70/30 Instrument Fittings are designed to deliver leak-proof connections, resistance to seawater corrosion, and long company life in programs ranging from marine engineering to offshore strength systems.
Cu 70/30, or Copper-Nickel 70/30 (UNS C71500), is an alloy composed of 70% copper and 30% nickel, alongside trace amounts of iron and manganese to enhance corrosion resistance and electricity. Known for its tremendous resistance to pitting, erosion, and biofouling, this alloy is notably utilized in exceedingly corrosive environments, especially in seawater and brine structures.
Cu 70/30 Instrument Fittings are small yet critical components used in instrumentation systems for measuring, monitoring, and controlling fluids and gases. These fittings make certain tight, durable, and leak-free connections in pipelines and tubing systems under excessive-strain and excessive-temperature situations.
