Choke & kill manifold

Skid-mounted drilling choke manifold to API 16C with API 6A 6BX ring-joint connections: 4-1/16" inlet through two gate valves into a studded-cross header, one branch per choke (hydraulic remote chokes with rotary actuators and hoses to a panel junction plate, manual adjustable chokes with handwheels) plus a full-bore bypass with a target block, a gate valve each side of every choke, and a buffer chamber with gauge, drain and two isolated 4-1/16" 5K outlets to the mud-gas separator and the shakers. Ports sit on the API faces; their rating is the nearest ASME B16.5 class (10K/15K → 2500, 5K → 1500).

Installation

Copies drilling/choke-manifold.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 { ChokeManifold } from './components/deck-twin/drilling/choke-manifold'

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

Props

P&ID

From the BOP choke line: two gate valves into a cross or header, then parallel branches each with a gate valve and a choke (bow-tie with a diagonal arrow), rejoining to the mud-gas separator or flare; a straight-through bleed line in the middle on many manifolds.

ISA HCVISA PVISA PIISA PTAPI 16C / API RP 53 well-control schematic, ISO 10628-2 valves

Production chokes on a tree are single valves; a choke manifold has several parallel choke branches with block valves. Only on well-control schematics.

For agents

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

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

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