Open drain hub / tundish

Deck open-drain collection point. Hub: a cast drain hub just proud of the deck, with a bowl falling to the outlet bore and a removable round bar grating. Tundish: a raised galvanised funnel with a rolled rim on a riser, giving an air break for PSV and instrument drain tails, with an optional grating. Both sit on a deck doubler with a penetration sleeve. The drain pipe runs down to a Class 150 weld-neck flange (port drain, kind drain) below the deck.

Installation

Copies piping/drain-hub.tsx and the shared lib/ into src/components/deck-twin/. Needs three, @react-three/fiber and @react-three/drei. See installation for the manual route.

Usage

import { Canvas } from '@react-three/fiber'
import { OrbitControls } from '@react-three/drei'
import { Stage } from './components/deck-twin/lib/stage'
import { DrainHub } from './components/deck-twin/piping/drain-hub'

export default function Scene() {
  return (
    <Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
      <Stage>
        <DrainHub />
      </Stage>
      <OrbitControls makeDefault />
    </Canvas>
  )
}

Props

P&ID

A funnel (V or trapezoid) open at the top with the drain pipe leaving the bottom to the open-drain (OD) header; drawn below the vents and drains of equipment that discharge into it.

tag DHtag TDISO 10628-2 / PIP PIC001 (funnel / tundish)

A funnel feeding an OD line = open drain hub or tundish. Closed drains (CD) are piped directly with no funnel.

Or fetch /r/drain-hub.json, or copy a ready-made instruction:

Add the Deck Twin "Open drain hub / tundish" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add drain-hub` (it copies the file and the shared lib into src/components/deck-twin/), then `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info drain-hub` for its props, ranges and ports. Render <DrainHub /> inside a React Three Fiber <Canvas shadows>, wrapped in <Stage> from src/components/deck-twin/lib/stage. Set props from my data (metres, NPS in inches, ASME class) and leave the rest at defaults. Install three, @react-three/fiber, @react-three/drei and @types/three if they're missing.
