Offshore used Electric Control Pneumatic Internal Pipe Clamp This clamp is mainly used for aligning two pipes in long distance offshore pipeline construction projects,Website:http://www.pipelineautoweld.com, equipped with copper backing shoes to support automatic welding. Control mode: electric control with battery alarm. Also can be pneumatic & electric double control according to the customers demand.Technical points and advantages of DP clamp: 1. Multi-cylinder design for small pipe size 6", 8", 10", providing stronger supporting force. 2. All welding parts, joints and pressing buckles on both ends of the hose are made of stainless steel, the carbon steel bearing parts are nitride treatment. All standard parts are anti-rust treatment. 3. This clamp can be modified to meet tributary line welding needs. Means the clamp can rotate 360°freely along with the pipe after the clamp has expanded to hold the pipes, ensuring no gas between pipes. 4. The copper backing shoes are made of heat-resistant alloy copper, normally each set of shoes can do 110 joints (average data between big and small pipe size). The material is of high strength, high hardness, high conductivity and high softening temperature etc. 5. Copper backing shoes performance parameter:HardnessConductivity IACSTensile strengthSoftening temperature80–84HRB85%610MPa930℃6. The copper backing device use double-spring & split type design to protect the copper shoes more effectively and make sure the copper shoes fit the pipe inner wall better.Mode and specification:      Model DKQ168TE DKQ219TE DKQ273TE DKQ324TE DKQ355TE DKQ406TE Applicable pipe size6″      Φ1688″      Φ21910″      Φ27312″      Φ32414″      Φ35516″-18″      Φ406-Φ457Product overallΦ120x1800Φ175x1360Φ170x1360Φ250x1560Φ280x1660Φ360x2040Weight105 kg130 kg140 kg135 kg180 kg260 kgNumber of clamp shoes4x24x26x28x210x210x2Number of copper shoes4x24x26x28x210x210x2Clamping force15T40T40T55T68T85TOperating valve control voltage24V24V24V24V24V24VBattery capacity2A·h2A·h4A·h4A·h8A·h8A·hModel DKQ508TE DKQ610TE DKQ711TE DKQ813TE DKQ914TE DKQ1016TE Applicable pipe size20″-22″      Φ508-Φ55924″-26″      Φ610-Φ66028″-30″      Φ711-Φ76232″-34″      Φ813-Φ86436″-38″      Φ914-Φ96540″-44″      Φ1016-Φ1117Product overallΦ470x2760Φ550x2810Φ650x2910Φ750x3060Φ850x3290Φ950x3340Weight535 kg690 kg860 kg1020 kg1320 kg1520 kgNumber of clamp shoes10x212x212x216x218x218x2Number of copper shoes10x212x212x216x218x218x2Clamping force150T183T270T270T450T650TOperating valve control voltage24V24V24V24V24V24VBattery capacity10A·h10A·h10A·h10A·h10A·h10A·h
