Hydraulic Internal Line-up Clamps

This pipe joint alignment device for mountainous terrain is a professional product designed by our company based on the construction requirements of mountain pipeline projects. It is suitable for adaptive pipe joint alignment on uphill, downhill, and curved pipe sections with slopes up to 40° and pipe diameters up to 500 mm. The equipment features excellent technical performance, simple operation, and a low failure rate. Its joint alignment accuracy reaches or exceeds that of similar imported products, fully meeting the process requirements of fully automatic welding for mountain pipelines.

Additional information

Description

High Degree of Automation

  1. The machine head adopts automatic rotation and automatically corrects deviation during travel;
  2. Automatically switches between high and low speeds in horizontal sections and slopes.

Core Technologies

  1. The equipment adopts a fully hydraulic drive, with strong clamping force; maximum working pressure up to 16 MPa;
  2. Uses a sealed oil tank design, allowing 360° rotation without oil leakage.

High Efficiency

  1. The traveling wheels use hydraulic adjustment, enabling quick and convenient setup. There is no need to lift the equipment to adjust the wheel height, greatly reducing adjustment time;
  2. Large-capacity battery: a single charge can meet the requirements for 60 pipe joint alignments.

Reliable Quality

  1. Reasonable structural layout with a stable hydraulic system;
  2. Major power components use well-known domestic and international brands, ensuring stable and reliable quality;
  3. High working pressure and strong clamping force allow effective alignment even on large wall thickness and diameter pipelines.

 

Features:

  • Adaptable pipe diameter: 6D;
  • Suitable for curved pipe sections with diameters up to 500 mm, providing adaptive joint alignment with high precision, without the need for external straight pipe extensions;
  • Capable of uphill and downhill operation on terrain with slopes up to 40°.
