Key Benefits & Engineering Features

Key Advantages of SS 304 ERW Pipes

Engineered for cleanability, structural reliability, and cost-effective fluid conveyance across industrial sectors.

Food & Beverage Transfer Lines

Used in selected milk, beverage and food-processing systems where cleanable pipe surfaces and resistance to routine process exposure are important.

Water Treatment Systems

Suitable for compatible water distribution lines, filtration equipment and plant connections, helping reduce reliance on coated steel pipes.

Industrial Fabrication

The welded pipe format supports fabrication of equipment frames, manifolds and pipe assemblies to specified dimensions.

Welded Piping Installations

SS 304 can be fabricated into connected pipework using qualified welding procedures, with weld quality and surface condition selected for the service.

General Chemical Handling

Suitable for certain non-chloride chemical lines when material compatibility is confirmed before installation.

Practical Grade Selection

SS 304 can be a suitable option for general industrial service, while chloride-rich, coastal or more aggressive chemical environments may require SS 316 for better pitting resistance.

Common Queries

Frequently Asked Questions

Clear technical answers to frequent queries regarding SS 304 ERW pipe supply and specifications.

SS 304 ERW Pipes are stainless steel pipes made by forming steel strip into a tube and joining the longitudinal seam using electric resistance welding. They are commonly selected for fabrication and industrial applications requiring the properties of grade 304.

The UNS designation is S30400. The grade is also commonly identified as 1.4301, X5CrNi18-10 and SUS 304 under other designation systems.

They are suitable for some chemical services, but compatibility depends on the chemical composition, concentration, temperature and exposure conditions. SS 304 should not be assumed suitable for every corrosive environment.

The relevant standard depends on the intended service and product type. ASTM A312 and ASTM A778 cover different categories of austenitic stainless steel pipe and tubular products. Buyers should confirm the exact standard required for their application.
