1 Pcs 1-1/2″ OD 304 Stainless Steel Tube, 16″ Long
Product: 1-1/2″ OD, 16″ long. Material: 304 stainless steel for high corrosion resistance and good weldability. Thickness: 1.5 mm. Best for short, straight runs where a compact piece is needed. Caution: ensure proper processing tools for threading or welding to fit your project.
Hicarer 1 Pcs 1-1/2″ OD 304 Stainless Steel Tubing, 24″ Length
Product: 1-1/2″ OD, 24″ length. Wall thickness: 1.5 mm. Material: 304 stainless steel for stability and durability. Finish: finely polished surface for a cleaner appearance. Best for mid-length projects requiring a smooth exterior. Caution: verify your assembly length as 24″ may require cutting or trimming for tight spaces.
Hicarer 1 Pcs 1-1/2″ OD 304 Stainless Steel Pipe, 36″ Length
Product: 1-1/2″ OD, 36″ length. Wall thickness: 1.5 mm. 304 stainless steel offers high strength and corrosion resistance. Surface is smooth for better aesthetics and handling. Best for longer runs or modular installations where fewer joints are preferred. Caution: longer tubes can be harder to maneuver in tight spaces.
Hicarer 2 Pcs 1-1/2″ OD 304 Stainless Steel Tubing, 24 in
Product: 2 pieces at 24″ length each. Wall thickness: 1.5 mm. Made from high-strength 304 stainless steel. Smooth surface finish reduces friction during fitting and welding. Best for dual-line setups or parallel-length constructions. Caution: ensure both pieces align in diameter and wall tolerance for clean joints.
M METERXITY 45 Degree Mandrel Bend Elbow, 1.5 Inch
Product: 45-degree mandrel bend elbow, outer diameter 1.5 inches, wall thickness 1.5 mm, height 140 inches. Material: 304 stainless steel. Designed for exhaust, pipe connections, or rail applications. Best for custom exhaust routes or structural connections where a precise bend is required. Caution: verify the bend radius fits your layout to avoid clearance issues.
1.5 Exhaust Pipe, Flared End 12″ Length
Product: 1.5″ OD exhaust pipe with flared end for a 12″ length. Material: T304 stainless steel for rust resistance and heat tolerance. End features are designed for a tighter seal in universal exhaust connectors. Best for quick-fit modifications. Caution: flared ends require proper tooling to ensure leak-free connections.
X AUTOHAUX 4 Pcs 1.5 Inch Bend Tube Exhaust Elbow
Product: 4 pieces of 45-degree SS304 bend elbows. Outer diameter 1.5 inches, wall thickness 1.5 mm. Designed to withstand high temperatures and pressures. Best for enhancing stability in exhaust configurations or custom piping. Caution: ensure clamps fit the 1.5″ diameter and that the bends align with your routing plan.
1.5 Inch Exhaust Pipe T304 Stainless Steel Straight Tubing
Product: Straight tubing with 1.5″ outer diameter, T304 stainless steel. Designed for universal applications across cars, trucks, and motorcycles. Features a precision-flared end for a leak-proof connection. Best for straight exhaust runs or adapters. Caution: verify the total length to ensure a proper fit in your vehicle or structure.
Buying Guide
What should you consider when choosing 1.5 inch stainless steel pipe?
- Length and flexibility: Short pieces are easier to maneuver; longer tubes reduce the number of joints but can be heavier and harder to install.
- Wall thickness: Most options here use around 1.5 mm; thicker walls improve impact resistance and corrosion resistance but add weight and cost.
- Alloy and finish: 304 stainless steel offers good weldability and corrosion resistance; ensure the finish is compatible with your processing method (welding, threading, or clamping).
- Bend options: Mandrel bends maintain diameter through curves, reducing bottlenecks in exhaust or piping paths.
- End treatments: Flared or slotted ends affect seal integrity and ease of installation; choose based on connector types and clamps.
How to measure and prepare for installation?
- Accurately measure available space to select length with minimal waste or joints.
- Plan for joints and clamps to maximize structural integrity and ease of assembly.
- Prepare for welding or threading with appropriate tools and safety precautions.
Frequently Asked Questions
- What is the standard outer diameter for a 1.5 inch stainless steel pipe? Answer: The typical outer diameter is 1.5 inches (38 mm) for this category.
- Is 304 stainless steel suitable for exhaust applications? Answer: Yes, 304 stainless steel provides good corrosion resistance and heat tolerance for many exhaust and fabrication projects.
- Should I choose a longer piece to reduce joints? Answer: Longer lengths can reduce joints but may be harder to install and transport; balance length with workspace.
- What is mandrel bending and why use it? Answer: Mandrel bending uses a mandrel inside the pipe to maintain a constant diameter through bends, reducing kinks and maintaining flow.
- Do these pipes require special tools for installation? Answer: Depending on the project, you may need threading, welding equipment, clamps, or cut-off tools suitable for stainless steel.
- What safety considerations apply when cutting or welding stainless steel? Answer: Use proper PPE, ventilation, and follow welding guidelines for stainless steel to prevent burns, fume exposure, and corrosion risk.
