Industrial Piping Kit — 36 mating parts across DN50–DN150, at true real-world scale, built for plant simulation and digital twins as well as games

Every part is modelled from exact CAD solids in metres to consistent PN16-style proportions, so every part of the same DN mates flange-to-flange — bolt circle, bolt count and raised face all match. The pipe axis sits at the origin for snapping, real design dimensions are published in an included table, and each part carries a convex collision mesh. Delivered as USD, glTF/GLB, FBX, OBJ and STEP CAD source — the geometry stays measurable and re-usable, not only renderable.

Not AI-generated. Not photogrammetry. Parametric CAD.

Where this is used

• Plant and refinery digital twins where pipe runs must actually connect
• Process simulation and engineering visualisation
• Synthetic data generation for industrial inspection
• Ship, factory and warehouse environments in games and film

Engineering-standard dimensions (not eyeballed)

• Flange OD / bolt circle / bolt count follow EN 1092-1 PN16: DN50 165/125/4×M16 · DN80 200/160/8×M16 · DN100 220/180/8×M16 · DN150 285/240/8×M20
• Pipe outside diameters are ISO/ASME: 60.3 / 88.9 / 114.3 / 168.3 mm
• Valve face-to-face lengths follow EN 558 series 15: 250 / 280 / 300 / 350 mm
• Valve body, bonnet and handwheel use typical PN16 proportions (generic, not a specific manufacturer's product)
• DIMENSIONS.csv / .md included: design size (mm) and triangle counts for every part

Quality control — every part passed an automated 4-stage QC before packaging (reports included)

• Closed (watertight) solids, dimensions re-measured after export
• UV 0–1 with 0 % overlap, texture resolution and fill verified
• glTF re-import scale check, zero overlap between parts in the kit layout

What you get

• Per part: LOD0–LOD3 + convex UCX collision mesh (Unreal naming)
• Textures: per size a 4K valve atlas, a 4K piping atlas and a 1K bolt atlas — BaseColor, Roughness, Metallic, Normal (tangent, OpenGL), AO. Procedural weathering, no baked lighting
• Formats: FBX (per part, LODs + collision), glTF/GLB (one file per size, textures embedded), OBJ + MTL, USD (kit), Blender 5.0 .blend (kit), STEP CAD source for all 36 parts
• Real-world scale in metres; Z-up in Blender, Y-up in FBX / glTF; pipe axis on the origin so parts snap together
