What is the difference between seamless and welded stainless steel pipes?

Seamless pipes are made from a solid billet for high-pressure use, whereas welded pipes are made from steel strips and are more economical for structural applications.

Can you provide Schedule 40 and Schedule 80 wall thicknesses?

Yes, we offer a full range of wall thicknesses including Sch 5S, 10S, 40S, and 80S, with customizable OD and thicknesses.

Stainless steel pipe

Stainless steel is a corrosion-resistant alloy composed primarily of iron (Fe), with a minimum of 10.5% chromium (Cr) (required for passive oxide layer formation). Additional elements like nickel (Ni), molybdenum (Mo), manganese (Mn), and nitrogen (N) are often added to enhance specific properties.
