FAQ

Frequently Asked Questions About S355 Pipes

What makes S355 Carbon Steel Pipes suitable for hydraulic applications?

Boasting a minimum yield rating of 355 MPa combined with balanced material density, this grade easily contains sudden internal fluid shocks. This structural baseline prevents micro-ruptures during repetitive hydraulic strokes.

Can S355 carbon steel tubes be used at low operational temperatures?

Yes. S355 carbon steel tubes are chemically calibrated to prevent low-temperature brittleness under severe shock loads. Tough sub-grades like S355J2 are certified via Charpy tests to maintain complete impact safety down to -20 degrees C.

What are the recommended welding procedures for S355 pipes?

This grade maintains a low carbon threshold limited to 0.22 percent maximum, providing excellent field weldability. They are easily joined using MIG, TIG, or submerged arc welding methods without the strict necessity of preheating on standard dimensions.

Do you supply customized wall thicknesses for S355 structural lines?

Yes. Our warehouse carries standard configurations including Sch 40, Sch 80, Sch 160, and heavy-wall Sch XXS. We also fulfill custom requests for outside diameters spanning from 10 mm up to 508 mm, along with precision cut-to-length solutions.

What surface treatment finishes are available for S355 pipe exports?

To shield raw metal against oxidation during maritime transit, we provide custom exterior coatings. Buyers can specify long-lasting black paint, anti-rust oiling, or thick hot-dip galvanization depending on the installation site criteria.
