EZDCC216 Double Chain Clamp 10" - 216"

Mathey Dearman EZDCC216 Double Chain Clamp is an extra heavy-duty alignment and reforming tool designed for precise pipe fit-up in welding, fabrication, and industrial piping applications. Engineered for oversized pipes, this double-chain clamp provides secure, distortion-free alignment and reforming for pipes and vessels from 10" to 216" (254 mm to 5486 mm) up to Schedule 80 wall thickness, handling elbows, tees, flanges, end caps, and fittings while keeping all areas accessible for welding without distortion.

• Model Number: EZDCC216
• Product Type: Double Chain Pipe Alignment Clamp
• Color: Silver/Gray
• Material: Heavy-duty steel (standard); available in stainless steel versions with nickel-plated or stainless steel high-strength leaf chains and extra heavy-duty stainless steel jackbars

• Overview: Extra heavy-duty double-chain clamp for aligning and reforming large pipes, elbows, tees, flanges, and fittings; covers multiple cage clamp ranges; ideal for oil and gas, shipbuilding, pipeline assembly, and structural construction
• Key Features:
  • Double-chain design: Distributes clamping pressure evenly to prevent pipe distortion
  • Precision alignment: Quick-adjust mechanism and jackscrew pads pivot independently for 0.5 mm accuracy on internal/external diameters
  • Versatile fit-up: Handles oversized pipes up to 20 ft long and complex fittings that cage clamps cannot
  • Quick setup: Easy chain attachment with double chain lock devices and jackscrew adjustments for rapid deployment
  • Accessibility: High-rise jackbars allow full welding access without removal
  • Durability: Corrosion-resistant materials withstand harsh environments and heavy reforming on thick walls
  • Safety: Includes cable hoist for secure support; reduces misalignment risks for enhanced weld quality and operator efficiency
