D16 Welding Table for Pipe Welding and Pipe Fixture Positioning Work

Achieve precise fit-up of all kinds of tubular components with our D16 Welding Table for Pipe Welding and Pipe Fixture Positioning Work. Built on the proven 3D flexible fixturing system with Φ16 H7 holes and a 50×50 mm grid, this five-sided machined platform solves the core challenges in pipe fabrication: pipe rolling, concentricity control, angular positioning and flange squareness. Reconfigure fixtures in minutes for different tube specifications, greatly cutting the cost of custom jigs and stabilizing your welding tolerance.

• Flatness: Standard ≤0.1 mm/1000 mm; high-precision (Grade 0) version can reach 0.05 mm/1000 mm (for robotic welding).
• Positioning accuracy: ±0.03 to ±0.05 mm.
• Platform dimensions: 1000×800 mm, 1200×1000 mm, 2400×1200 mm, etc.; supports modular assembly (splicing) for extended lengths.
• Load capacity: 3–10 tons per unit (standard); suitable for small-to-medium-sized pipe assemblies.
• Surface treatment: Nitriding, shot blasting; cast iron versions undergo artificial aging (stress relief) to minimize welding-induced deformation.

Designed specifically for the welding of round pipes, square pipes, pipe assemblies, pipe-and-flange combinations, pipe supports, and piping frameworks:

1. Utilizes V-blocks, flange positioning discs, adjustable supports, quick-locking pins, and clamps to rapidly secure pipes in precise spatial positions.
2. Ensures consistent pipe concentricity, spacing, flange perpendicularity, and angular dimensions.
3. A single D16 welding table system can be reconfigured for various setups, eliminating the need for custom-made fixtures for every individual pipe type.
4. Suitable for both manual welding and robotic pipe-welding workstations.

• V-blocks: Support round pipes and prevent rolling; available for various pipe diameters.
• Flange positioning fixtures: For aligning flanges with pipes during butt welding.
• Adjustable support columns, angle squares, and corner positioning blocks.
• Quick-locking pins, toggle clamps, and extension/connecting modules.
• Compatible for use with welding positioners and rotary fixtures.

1. Inner Protection: The tabletop is coated with anti-rust oil, then wrapped in VCI (Volatile Corrosion Inhibitor) film and a waterproof stretch wrap. Foam protective pads are applied to machined surfaces and the edges of holes to prevent scratches, impacts, and rust caused by moisture during ocean transit — with a special focus on preserving the flatness and precision of the welding table.
2. Outer Packaging:
   • Small to medium sizes (1200×1000 ~ 2400×1200 mm): Fumigation-free solid wood crates, suitable for LCL (Less than Container Load) shipments.
   • Large tabletops (3000×1500 mm, 4000×2000 mm): Reinforced, fumigation-free wooden pallets, secured with steel strapping. Lifting points are clearly marked to facilitate handling by forklift.
   • Fixture accessories (V-blocks, locking pins, clamps) are packed separately in export-grade cartons.

• Shipping Methods: Sea freight (FCL/LCL), rail, and air freight.
• Available Terms: EXW, FOB, CIF, CFR, DAP, DDP (door-to-door service supported).
• Ports of Departure: Shanghai, Ningbo, Guangzhou, etc.
• Lead Time: 15–20 business days for standard-sized units; longer lead times apply to Grade 0 high-precision models and extra-large modular units.
