The minimum possible diameter of a seamless pipe depends on the material, manufacturing process, wall thickness, and manufacturing capabilities. Small-diameter seamless tubes are available for specialized industrial applications, but the exact minimum size varies by manufacturer and product specification. When selecting a seamless pipe, consider the outside diameter, wall thickness, operating pressure, temperature, material grade, and applicable industry standards. These factors help determine the most suitable pipe for applications in oil and gas, petrochemicals, power generation, and engineering. For accurate sizing information, consult a steel tube manufacturer or supplier and request product specifications based on your application requirements.

Seamless pipe
The main difference between hot-finished seamless pipes and cold-drawn seamless pipes is the manufacturing process and the resulting dimensional accuracy, surface finish, and mechanical properties. Hot-finished seamless pipes are processed at elevated temperatures, making them suitable for various industrial applications where strength and dimensional requirements can be met by the finished product. Cold-drawn seamless pipes are further processed by drawing the steel through a die, typically at room temperature. This process can provide tighter dimensional tolerances, a smoother surface finish, and improved mechanical properties, depending on the material and processing conditions. Hot-finished pipes are often selected for general industrial and high-temperature applications, while cold-drawn pipes are useful where precision, dimensional consistency, and surface quality are important. The best option depends on the steel grade, pipe dimensions, operating conditions, and applicable standards. Buyers should compare the required specifications before selecting a seamless pipe for their application.
The difference between seamless and welded (as it is commonly known) pipes is the welded joint along the longitudinal direction. Seamless pipes are manufactured by continuous extrusion process. Seamless pipes have greater bursting and tensile strength than the welded ones.
Yes as seamless is always better
Seamless (SMLS) pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. Seamless pipe withstands pressure better than other types, and is often more easily available than welded pipe.Welded pipe is formed by rolling plate and welding the seam. The weld flash can be removed from the outside or inside surfaces using a scarfing blade. The weld zone can also be heat treated to make the seam less visible.

ERW (Electric Resistance Welding) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured by extruding the metal to the desired length; hence ERW pipe has a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length.
