Construction Sector: In water supply, drainage, heating, and gas systems of residential and commercial complexes, pipe fittings must meet requirements for pressure resistance, corrosion resistance, and strong sealing. For example, PPR pipe fittings, achieved through heat fusion connection, achieve leak-free operation and are widely used in drinking water pipelines; galvanized steel pipe fittings are used in fire protection systems to withstand the impact of high-pressure water flow.
Industrial Sector: Industries such as petrochemicals, power, and pharmaceuticals have extremely high performance requirements for pipe fittings. For example, stainless steel press-fit fittings are used to transport corrosive media, and their weld-free design avoids the risk of weld corrosion; high-pressure pipe fittings (such as API standard fittings) must undergo rigorous non-destructive testing to ensure safe operation in high-temperature and high-pressure environments.
Municipal Engineering: In urban water supply, drainage, and gas pipeline networks, pipe fittings must adapt to complex terrain and long-term underground environments. For example, ductile iron pipe fittings, through flexible joint design, can resist foundation settlement; PE pipe fittings achieve rapid installation through electrofusion connection, reducing construction costs.
Special scenarios: In extreme environments such as offshore platforms and nuclear power plants, pipe fittings must possess characteristics such as low-temperature resistance, radiation resistance, and explosion-proof properties. For example, titanium alloy pipe fittings are used in seawater desalination systems to resist chloride ion corrosion; Hastelloy pipe fittings are used in strong acid and alkali environments to ensure long-term stability.
