Stem leakage typically results from worn packing, misalignment, or surface damage. Prevention includes proper packing installation, maintaining alignment within 0.1mm, using corrosion-resistant materials, and implementing regular maintenance schedules with torque monitoring.
Material selection depends on fluid chemistry, temperature, and pressure. For acidic environments, use Hastelloy or titanium; for chloride-rich fluids, use super duplex stainless steel; for high-temperature steam, use heat-treated alloy steels with appropriate coatings.
