In the 'steel jungle' of industrial pipelines, valves act as silent water workers, controlling the flow of fluids. However, they often 'die young,' which is truly regrettable. Despite being part of the same batch, why do some valves retire early while others continue to serve? Today, let's follow fluid control expert Waters to uncover the truth behind the short lifespan of valves.
Three major causes of valve "short life"
Suffocation to Death: The Dual Struggle of High Pressure and Corrosion High Pressure Impact: When the system pressure far exceeds the valve's design limits, the valve body and seals are subjected to immense pressure, leading to structural deformation and seal failure. Instant water hammer impacts are like internal injuries, capable of instantly rendering the valve unusable. Corrosion Devouring: In harsh conditions such as chemical and seawater environments, corrosive media act like bone-softening palms, silently eroding the valve body wall thickness (with a corrosion rate exceeding 0.5 mm/year), weakening its strength, and causing perforation and leakage. Waters understands that materials are crucial, and its special alloy valves (such as Hastelloy and duplex steel) are like' golden bell shields, 'significantly enhancing their pressure and corrosion resistance. Overwork Wear: The Ruthless Cutting by High-Speed Fluids Media Erosion: Solid particles (such as mineral slurry and ash) or high-speed fluids (such as steam and cavitation water) continuously scour the sealing surface and valve chamber, acting like countless micro-engraving knives. Over time, these actions create deep grooves on the sealing surface, leading to seal failure. Waters' high-hardness alloy sealing surfaces (such as tungsten carbide and STL) and optimized flow path designs serve as 'iron shirts' against this relentless 'thousand cuts.'
Asphyxiation blockage: deadly blockage of impurities and scale
Impurities intrusion: Weld slag, rust, and foreign objects can enter the pipeline and get stuck between the valve seat and core. This can cause the valve to fail to close or open properly, and in severe cases, damage the precision sealing surface. Medium crystallization and scaling: In certain conditions (such as cooling water or slurry), the medium may crystallize or scale inside the valve, effectively locking the valve joints, leading to sluggish or complete blockage. Waters 'anti-clogging designs, such as large-flow V-type ball valves and scraper structures, serve as effective tools for clearing these' blood clots.'
The user's "mistake" accelerated the valve life
According to TWS Water-seal valve, valve longevity is not an accident, but a system engineering from design, material selection, manufacturing and use:
Accurate Matching, Tailored to the Specific: Conduct a thorough analysis of operating conditions (pressure, temperature, medium, particle content, and operating frequency) to select the optimal valve type (gate valve, globe valve, ball valve, butterfly valve) and material. Core Components, Striving for Perfection: The sealing pair is made from wear-resistant and corrosion-resistant hard alloy; the valve stem is made from high-strength corrosion-resistant materials with enhanced surface treatment; critical pressure-bearing components are rigorously verified through finite element analysis (FEA). Craftsmanship, Strict Quality Control: Precision machining ensures precise fit tolerances, and strict non-destructive testing (RT/UT/PT) eliminates internal defects; every process is a commitment to reliability. Smart Choice, Anticipating the Future: Offer professional selection guidance and customized solutions to ensure valves are 'born at the right time, in the right place.'
