Category	Details
Standard Pipe Dimensions	Outer Diameter (OD): 1/8" (0.375") to 48" (12.5 cm)
	Wall Thickness (WT): Varies from Schedule 10 to Schedule 160
	Schedules: 5, 10, 20, 40, 80, 160, XXS (Extra Extra Strong), etc.
Pipe Manufacturing Process	Seamless Pipe: Formed from a solid billet, no welding required
	Welded Pipe: Made from welded stainless steel coils
	ERW (Electric Resistance Welded): Uses electric resistance for welding
	Spiral Welded Pipe: Weld spirally wound around the pipe (for large sizes)
Surface Finishes	Mill Finish: Basic finish from manufacturing
	Pickled and Passivated: Removes scale and oxide for better corrosion resistance
	Polished: Mirror or satin finish for aesthetic and sanitary applications
	Brushed: Textured, non-reflective surface for architectural use
Applications	Industries Served: Food & Beverage, Chemical & Petrochemical, Marine & Offshore, Oil & Gas
