SERVICE 02 / SPECIAL JOINT / METAL AM

Create the future of piping from the flow path.

Complex branches and internal channels are integrated with metal AM and designed for the right balance of flow, strength, and manufacturability.

Multiple materials and complex geometries A complex piping manifold formed as one piece by metal additive manufacturing
SPECIAL JOINT / METAL AM
φ140×190mm Example metal AM build size Depends on equipment and geometry
LPBF Laser powder bed fusion For complex internal flow paths
Integration Fewer joints Feasibility reviewed in advance
METAL ADDITIVEMetal additive manufacturing

Design the flow path,not an assembly.

Where conventional construction assembles a complex branch from separate parts, metal additive manufacturing designs it as one piece, internal flow path included. Joints disappear and the flow stays smooth and continuous.

CONVENTIONAL

Conventional fabrication | Welded assembly

The conventional sequence: cutting branch pipes, aligning and assembling them, and welding at multiple points
  1. 01CuttingEach branch pipe machined separately
  2. 02AssemblyAlign position and angle
  3. 03WeldingJoin at multiple points
  • Multi-point welding makes it difficult to build
  • Flow is easily disturbed at the joints
  • Quality depends on operator skill
  • More points to manage for contamination and leaks
ENGINEERED FLOW

Metal additive manufacturing | Integrated flow path

A one-piece multi-directional branch with smooth, continuous form
Seamless integrated structure

A continuous internal flow path reduces turbulence, stagnation, and pressure loss.

  • A one-piece structure with no welds
  • A smooth, continuous internal flow path
  • Complex geometry reproduced as designed
  • Quality control points consolidated
Weld pointsMany→None
Internal flow pathDiscontinuous→Smooth
Contamination riskHigh→Reduced
Design freedomConstrained→High

Pressure loss can be reduced by up to 50%※* Simplified flow-analysis figures under our assumed conditions. Results vary with operating conditions and geometry.

ENGINEERED FLOW / 40A–32A

Move from welded assembly to an integrated flow-path design.

A complex branch that would otherwise be cut, aligned and welded at many points is designed as a single form with a continuous internal flow path. Fewer joints means flow, cleanliness and repeatability can be addressed together. Surface finishing after building is available up to #400 polish.

SANITARY MANIFOLD / 2S

Clean flow for high-purity applications.

Three- and four-outlet sanitary manifolds can also be designed as smooth flow paths with few joints.

01

Smooth flow path

Internal geometry designed for continuous flow.

02

Low contamination

A design that reduces seams and dead zones.

03

High reliability

A one-piece structure with minimal welding.

04

Design freedom

Flow paths optimised for the application.

ACONITY MINI metal powder bed fusion system

LPBF / ADDITIVE MANUFACTURING

A metal powder additive manufacturing system for precise builds.

Laser powder bed fusion (L-PBF) builds internal flow paths, thin-walled structures and complex geometries that are difficult to cut or weld. Build preheat reaches up to 800°C. The system is also used for metal powder development, where we have a track record. We design the whole route — building, machining, polishing and inspection — so the result stands up as a product.

MATERIAL / SAMPLE

Select materials and processes for the application.

Material is selected from your requirements for corrosion resistance, strength, heat resistance or weight. Rather than replacing everything with 3D printing, we also propose combinations with pipe forming, machining, polishing and welding.

  • SUS316L
  • M300F
  • Inconel 718
  • AZX912
* Feasibility is assessed individually against geometry, dimensions, quality requirements and post-processing conditions.
