Tee

Butt-welding equal or reducing tee with a forged crotch radius. Run centre-to-end C and outlet M from ASME B16.9 (reducing outlet M approximated), B16.25 weld bevels or welded weld-neck flanges. Origin at the run and branch centreline intersection; the outlet points up, down or sideways.

Installation

Copies piping/tee.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 { Tee } from './components/deck-twin/piping/tee'

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

Props

P&ID

A branch line meeting a run line; a dot at the junction confirms a connection (lines crossing without a dot or with a gap / hop are not connected).

ISO 10628-2 / PIP PIC001 (piping)

Reducing tees are shown by the different line sizes of run and branch. Crossing lines without a dot are not a tee. On isometrics the tee is drawn with weld ticks.

For agents

Machine-readable entry with props, ranges, defaults and ports:

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

Add the Deck Twin "Tee" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add tee` (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 tee` for its props, ranges and ports. Render <Tee /> 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.
