Applications and Industrial Uses of Stainless Steel 904L Pipe Fittings
- The fitting is also common in pipelines that carry corrosive acids in most chemical processing units and fertilizer plants, e.g. sulfuric and phosphoric acid.
- Critical in desalination unit and marine settings, where a chloride-saturated environment requires high-pitting and crevice resistance to corrosion.
- Applications in high temperature and pressure such as in oil and gas refineries and in offshore platforms and petrochemical installations.
- Ideally used in heat exchangers, power generation plants or where high thermal conductivity and long service life is needed.
- Its non-contaminating and hygienic characteristics are practical in pulp and paper sectors, the pharmaceutical sector, and in food processing plants.
- They are typically utilized in condenser tubes, pressure vessels, and pipeline joints that are to be connected to each other through a durable, welded or buttweld.
- It can be used in custom fabrication applications where SS 904L fittings are used to offer strength, ductility and good weldability in a broad selection of industries.
