Application of Stainless Steel Pipe Fittings in Sewage Treatment Projects

    Different sewage types exhibit varying levels of corrosion, pressure tolerance, and temperature characteristics, making it crucial to select suitable pipe fittings.

    Due to the large amount of grease and salt, the kitchen waste water is extremely corrosive to the pipe, making it necessary to choose 316L pipe fittings (S31603) that are resistant to chloridion (CI) corrosion. With excellent corrosion resistance, 316L stainless steel pipe fittings can effectively resist high cocentrations of chloride ions and oxidants, ensuring the smooth operation. Wastewater from desalination projects requires the use of superior materials such as 2205 or even 32750 super duplex steel pipes and fittings.

    In highly acidic environments, 316Ti stainless steel fittings are favored for their strong acid corrosion resistance. In high temperature working conditions, 310S stainless steel pipe fittings with good high-temperature stability becoming the first choice.

    Therefore, we need to carefully select according to the characteristics and treatment requirements of sewage, so as to ensure the normal operation and stability of sewage treatment system.

Stainless steel pipe fittings run through a number of key links of sewage treatment.

1. Sewage collection and transportation

2. Preprocess

It's the process of removing large particulate matter and suspended matter in sewage. Stainless steel pipe fittings are used to construct grilles and sand sinks.

3. Biological treatment system

It's the core link of sewage treatment. Stainless steel pipe fittings are used to construct biological treatment facilities such as activated sludge tanks and biofilm reactors.

4. Deep treatment and disinfection

Steel pipe and fittings are used to construct filters, disinfection tanks and other facilities to effectively remove residual contaminants and pathogens.

5. Sludge treatment and disposal

It plays a vital role in sludge concentration, dehydration, drying and other treatment processes.

6. Monitoring and control system

Ensure accurate data transmission and stable operation of the system
