Where Stainless Steel Pipe Is Actually Used
Stainless pipe follows whichever industry is growing. Four applications account for most of the volume, and each one specifies for a different reason.

Water Supply Drainage and Irrigation
Water supply and drainage engineering is a pipe system for conveying and distributing industrial water, drinking water, and for collecting and discharging industrial wastewater, domestic sewage and rainwater. Its investment accounts for the majority of total engineering investment on these projects. Sprinkler irrigation is an important part of agricultural water use, and the physical and chemical properties of stainless water pipe meet modern agricultural water treatment requirements.

Direct Drinking Water Networks
As drinking water quality expectations rise, urban systems use quality graded supply, with purification stations set up in residential quarters, hotels, office buildings and parks to deeply purify tap water. Stainless pipe is then used to build an independent circulating network that delivers the purified water directly to the user, which avoids secondary water pollution in the distribution leg.

Fire Protection Piping
Stainless fire fighting piping is a fixed fire protection facility widely used in China. Once the automatic alarm mechanism is activated, the sprinkler system sprinkles through the static flow in the stainless pipe and works together with other fire protection facilities, which controls and extinguishes an initial fire and reduces fire safety hazards.
Petrochemical Service
The petrochemical industry moves corrosive fluids including acids, alkalis and salts. Stainless pipe is specified because the corrosion resistance and oxidation resistance are properties of the material itself, which is what keeps the fluid contained over the life of the plant.

Choosing Across These Four
Water and fire duty is usually satisfied by 304, with 316L where chlorides are present. Drinking water networks favour 316L for its stability under repeated disinfection. Petrochemical service is driven by the specific medium, which is where 317, 321, TP347 and the nickel alloys come in.
