|Yes, seamless pipe is stronger than welded pipe because as its name suggests, the seamless steel pipe does not have a seam (crease) or a welded joint. The Seamless pipes are manufactured with a process called molded. It is made out of one single piece solid bar while welded pipes and tubes are made up of coil which is highly bendable & soft as compared to seamless steels. The Welded pipes have a seam on the surface or inside the pipe depending on the manufacturing process as it varies from different brands. The seamless material can bare maximum strength pressure and does not bend, crack or break which is highly required in making engineering jobs wherein, the Welded (ERW/EFW) may unfold its seam while applying maximum pressure above its tolerance range. The seamless pipe is majorly used in petroleum, oil & gas industries for pressure segments. One of the leading manufacturers is Seamless Steel Industries based in India - Maharashtra a wide supplier of Seamless and Welded pipes. https://www.seamlesssteelindustries.com ST-52 Round Tube is appreciated for its features such as durability, application-specific design, and dimensional accuracy.

What are St52, St52.3, and St52.4 Seamless Pipe
American steel grade German steel St52
The "St" means a general structural carbon steel (that is, plain carbon rather than low alloy) that is not intended to be heat treated (that is, other than the heat treatment which naturally occurs during cool-down from the hot-rolling operation). The "52" means a minimum tensile strength of 52 kg per sq. mm. In SI units, this is 510 MPa. In Imperial units, it's 73,961 (that is, in practice, 74,000 or 75,000) psi.
