Seamless steel pipes are meant for high pressure applications in plumbing and fire fighting applications. This also includes Chiller areas where high pressure fluid flow demand safer passage with weld less joints. Extruded from Steel billets, these SMLS pipes are widely used in Oil and Gas & Fire Fighting applications considering the safety aspects. Various standards specially UL / FM, ASTM , ASME focus on this for prestigious government jobs across the globe. This applies not only to Mild steel but to carbon steel and even stainless steel. Higher the psi demands in the fluid flow, far higher will be the need for unwelded joints; hence local codes in bigger project demand these pipes for better safety and pressure conditions as required.
