Compare the measured dimensions to manufacturer specifications to ensure compliance and identify any deviations that may indicate hydrogen embrittlement-related distortion or swelling.
  3. Microstructural Examination: Perform microstructural examination of the malleable threaded fittings using metallographic techniques such as optical microscopy or scanning electron microscopy (SEM). Evaluate the grain structure and morphology of the material to identify any signs of hydrogen-induced microcracking, intergranular fracture, or embrittlement.
  4. Hardness Testing: Conduct hardness testing on the malleable threaded fittings using a portable hardness tester or microhardness indenter. Measure the hardness of the material at various locations, including threaded areas and heat-affected zones, malleable threaded fittings  to assess for any changes in hardness that may indicate hydrogen embrittlement.
  5. Ultrasonic Testing (UT): Consider performing ultrasonic testing to detect internal defects or discontinuities in the malleable threaded fittings. UT involves sending ultrasonic waves through the material and analyzing the reflected signals to identify potential flaws, cracks, or voids caused by hydrogen embrittlement.
  6. Hydrogen Permeation Testing: Implement hydrogen permeation testing to assess the susceptibility of the malleable threaded fittings to hydrogen embrittlement. This involves exposing the fittings to hydrogen gas under controlled conditions and measuring the rate of hydrogen diffusion into the material to determine its hydrogen absorption capacity.
  7. Corrosion Assessment: Evaluate the corrosion resistance of the malleable threaded fittings and assess the extent of any corrosion damage that may contribute to hydrogen embrittlement. Look for signs of corrosion, rust, or pitting on the surface of the fittings, and consider conducting corrosion testing to quantify corrosion rates and susceptibility.
  8. Material Analysis: Analyze the chemical composition of the malleable threaded fittings to identify any elements or impurities that may promote hydrogen embrittlement. Pay particular attention to elements such as sulfur, phosphorus, and carbon, which can enhance susceptibility to hydrogen-induced cracking.
  9. Documentation Review: Review documentation related to the manufacturing, processing, and handling of the malleable threaded fittings to identify any potential sources of hydrogen embrittlement. Evaluate material certificates, heat treatment records, and process parameters to ensure compliance with industry standards and best practices.

By following these inspection techniques and procedures, you can effectively assess malleable threaded fittings for signs of hydrogen embrittlement and take appropriate corrective actions to mitigate the risk of failure or structural damage. Regular inspection and monitoring are essential for maintaining the integrity and reliability of piping systems in various industrial applications.
