Note: All listed products are seamless stainless steel tubes suitable for threading or welding. Availability and exact specifications may vary by seller. Use proper safety equipment when cutting or joining metal tubes.
MOKOVI 1/2″ Stainless Steel Tube, 16″ Long
Product: 2 Pieces • Size: 1/2″ OD (12.7mm); Length: 16″ (406mm); Wall Thickness: 1.5mm. Material: 304 stainless steel with high strength and weldability. Noted for good corrosion resistance. Processing: can be threaded or welded to required length using professional equipment. This makes it a versatile option for light structural frames, supports, or custom piping projects.
M METERXITY 300mm 30mm OD Stainless Tube
Product: 1 piece • Length: 300 mm (12″); Outer Dia.: 30 mm; Wall: 1.5 mm. Material: 304 stainless steel. Features versatility for industrial construction, machining, and DIY projects. Highlights include high tensile strength, corrosion resistance, and malleability for shaping, bending, or joining with other components.
MOKOVI 1″ OD Stainless Steel Tube, 16″ Long
Product: 2 Pieces • Size: 1″ OD (25mm); Length: 16″ (406mm); Wall Thickness: 1.5mm. Material: 304 stainless steel with strong weldability and corrosion resistance. Suitable for projects requiring a larger bore, such as frames, supports, or ductwork segments. Processing guidance includes threading or welding to fit project specifications.
uxcell 304 Stainless Steel Tube, 16mm OD
Product: 1 piece • Inner Diameter: 10 mm; Outer Diameter: 16 mm; Length: 305 mm. Wall Thickness: 3 mm. Material: 304 stainless steel. Applications include structural parts in industry, ship models, construction, machinery, pipelines, and DIY projects. These capillary tubes can be machined, punched, and welded to suit specific designs.
Vigorous 1-3/4″ OD Stainless Tube
Product: 2 Pieces • Size: 1-3/4″ OD; Length: 1 ft; Wall Thickness: 2 mm. Material: 304 stainless steel. Features a smooth-bore seamless construction for reliability. Common uses include DIY crafts, frames, and industrial equipment where a larger diameter is advantageous. 304 stainless steel provides corrosion resistance and ease of maintenance.
Buying Guide: Key Purchase Considerations
- Material grade: Most listed items use 304 stainless steel, preferred for general structural and piping applications due to corrosion resistance and weldability. Consider 316/other alloys for high-salinity or highly corrosive environments.
- Diameter and wall thickness: Choose a diameter that matches your connection fittings or design needs. Thicker walls increase strength but add weight and cost; thinner walls are easier to cut or thread but less rigid.
- Length and tolerance: Verify exact lengths and tolerances to ensure proper fit in assemblies. Some tubes are sold in specific increments (e.g., 12″, 16″, or metric equivalents).
- Processing compatibility: If you plan threading or welding, confirm the tube’s machinability and any required finishing (deburring, cleaning).
- Corrosion exposure: For coastal or chemical environments, prioritize higher alloy content and tighter fabrication controls to minimize corrosion risk.
- Availability and packaging: Some products are sold as sets (e.g., two pieces) which may affect project planning and cost efficiency.
- Fabrication readiness: Ensure you have access to the proper tools (pipe cutter, deburring tool, welder, threading gear) and safety equipment.
