Titanium Pie Cuts

Our Titanium Pie Cuts (also known as titanium wedge cuts, titanium bend segments, or titanium pipe slices) are precision pre-machined tubular segments, engineered to solve the core pain points of custom piping fabrication: inconsistent hand cutting, uneven weld gaps, material waste, and excessive fabrication time. Each segment is precision cut from high-quality titanium tubing, with a fixed included angle per piece, allowing fabricators to assemble perfect custom bends, complex manifolds, and tight-clearance piping routes by simply tacking and welding the segments together.

Widely used in high-performance automotive & motorcycle exhaust systems, racing engine headers & manifolds, marine engineering piping, aerospace hydraulic lines, chemical custom process piping, and medical equipment tubing, our titanium pie cuts are fully compatible with standard titanium tubing, flanges, and fittings, making them the most flexible and efficient solution for custom titanium piping fabrication.

1.CNC Laser Precision Cutting for Zero-Error Fit : 

Adopt high-precision 5-axis CNC laser cutting technology, with angle tolerance controlled within ±0.1°, outer diameter tolerance ±0.05mm. Every piece has a perfectly matched cut face, ensuring zero gap alignment when assembled, eliminating uneven weld gaps, misalignment, and rework common with hand cutting. The consistent angle and dimensions guarantee a smooth, uniform bend radius across the entire assembly, with no distortion or irregularity.

2.Seamless & Welded Dual Base Material Options : 

We offer two core base material options to meet different application needs:

- Seamless Titanium Pie Cuts : Cut from seamless titanium tubing (ASTM B861), no longitudinal weld seam, higher pressure bearing capacity, better fatigue resistance, ideal for high-temperature, high-pressure, high-vibration applications like turbo manifolds, aerospace hydraulic systems, and high-pressure process piping.

- Welded Titanium Pie Cuts : Cut from high-quality longitudinally welded titanium tubing (ASTM B338), with uniform wall thickness, lower cost, and shorter lead time, perfect for performance exhaust systems, medium-pressure process piping, and cost-sensitive fabrication projects.

3.Full Radius & Angle Range for Unlimited Fabrication Flexibility : 

We offer a complete range of centerline radius (CLR) and per-piece angle options, giving you unlimited flexibility to create any bend shape or angle:

- Standard CLR options: 1D (tight radius), 1.5D, 2D, 3D (loose radius)

- Standard per-piece included angles: 9° (4.5° per side), 15° (7.5° per side), 22.5°, 30°, 45°

- Assemble any total bend angle from 9° to 360°: 10pcs of 9° cuts make a perfect 90° bend, 6pcs of 15° cuts make a 90° bend, etc.

- "Clock" the segments at different rotations to create compound bends, snake around obstacles, and build complex 3D piping routes that are impossible with pre-formed mandrel bends.

4.Pre-Machined Weld Bevel & Deburred Finish : 

Every piece comes standard with a precision machined 30°/37.5° weld bevel on both cut ends, fully compliant with ASME welding standards for optimal weld penetration. All edges are fully deburred and smoothed, with no sharp edges or burrs. This eliminates the need for on-site grinding, beveling, and surface preparation - our pie cuts are ready to weld straight out of the package, further reducing your fabrication time and labor cost.

5.Premium Titanium Material Performance : 

Manufactured from aerospace-grade titanium materials, our pie cuts deliver exceptional performance in harsh environments:

- Continuous working temperature up to 550℃ for Grade 5 titanium alloy, perfect for high-temperature exhaust and turbo manifold applications.

Q: What are Titanium Pie Cuts, and what are they used for?

A: Titanium Pie Cuts are precision pre-cut wedge-shaped segments of titanium tubing, designed to be welded together to form custom bends, manifolds, and complex piping routes. They eliminate the need for hand-cutting tubing on-site, allowing fabricators to assemble perfect custom bends of any angle or shape by simply tacking and welding the segments together. They are most commonly used for high-performance exhaust systems, racing engine manifolds, custom marine piping, aerospace hydraulic lines, and any application requiring complex custom titanium piping.

Q: What's the difference between 1D tight radius and 1.5D/2D loose radius pie cuts? How do I choose?

A: The core difference is the centerline radius (CLR) of the bend, which affects the space required and flow efficiency:

- 1D Tight Radius : The bend radius is equal to the tube outer diameter, creating a very compact, tight bend. It's the ideal choice for tight-clearance engine bays, motorcycle exhausts, and applications where space is limited.

- 1.5D/2D Loose Radius : The bend radius is 1.5-2 times the tube outer diameter, creating a smoother, more gradual bend. This reduces fluid turbulence and back pressure, making it the preferred choice for high-performance exhausts, turbo manifolds, and applications where flow efficiency is critical.We can recommend the optimal radius based on your space constraints and flow requirements.

Q: What per-piece angle should I choose? What's the difference between the standard angles?

A: The per-piece included angle determines how many pieces are needed to make a 90° bend, and the flexibility of your fabrication:

- 9° per piece : 10 pieces make a 90° bend, offering the highest flexibility for fine angle adjustment and complex compound bends, ideal for tight-clearance routing and precision manifold fabrication.

- 15°/22.5° per piece : 6/4 pieces make a 90° bend, balancing flexibility and assembly speed, with fewer welds per bend. This is the most versatile option for most general custom fabrication projects.

- 30°/45° per piece : 3/2 pieces make a 90° bend, with the fastest assembly speed and minimal welds, ideal for simple standard bends, large-diameter piping, and cost-sensitive projects where the number of welds needs to be minimized.

Q: What's the difference between seamless and welded base material pie cuts? How do I choose?

A: The core difference lies in the base tubing material and performance:

- Seamless Pie Cuts : Cut from seamless titanium tubing, with no longitudinal weld seam. They offer higher pressure bearing capacity, better fatigue resistance, and superior performance in high-vibration, high-temperature, high-pressure applications. They are the preferred choice for turbo manifolds, aerospace hydraulic systems, high-pressure process piping, and professional racing applications.

- Welded Pie Cuts : Cut from high-quality longitudinally welded titanium tubing, with a fully tested and certified weld seam. They offer more uniform wall thickness, lower cost, and shorter lead times, making them ideal for performance exhaust systems, medium-pressure process piping, marine exhausts, and general custom fabrication projects.Both types are 100% inspected to ensure compliance with relevant standards.
