Ham-Let Let-Lok® Hastelloy® C-276 Twin Ferrule Tube Fittings

The Let-Lok® range of connectors has been developed by Ham-Let to fill the rapidly increasing demand for tube fittings suitable for high pressure use in environments such as:

  • Petrochemical
  • Electronic
  • Nuclear
  • Fluid power

Ham-Let Let-Lok® tube fittings have been carefully manufactured and tested to withstand the demands made of high performance tube fittings, such as high pressure, vacuum, vibration, temperature and impulse.

Ham-let Let-Lok® tube fittings are manufactured to exacting tolerances using the most modern and advanced computerised automation.

In aggressive/corrosive service, when nothing else works, many industries have traditionally turned to Hastelloy® C-276 alloy. Many years of outstanding performance in a variety of industrial applications have confirmed the advantages of using this alloy. Excellent Resistance to Corrosion Hastelloy® C-276 alloy is a nickel-molybdenumchromium wrought alloy that is generally considered a versatile corrosion-resistant alloy. C-276 alloy has excellent resistance to localized corrosion and to both oxidizing and reducing media. Because of its versatility, C-276 alloy can be used where “upset” conditions are likely to occur in multipurpose plants. Hastelloy® C-276 alloy has excellent resistance to a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, hot contaminated media (organic and inorganic), chlorine, formic and acetic acids, acetic anhydride, and seawater and brine solutions. It is used in flue gas desulfurization systems because of its excellent resistance to sulphur compounds and chloride ions encountered in most scrubbers. C-276 alloy has excellent resistance to pitting and to stress-corrosion cracking. It is also one of the few materials that withstands the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide.
