7. Application Considerations for Pipeline Forming Equipment

• Select the appropriate pump series and model based on the specific pipeline forming function (bending, flaring, swaging, or beveling) and pipe diameter range.
• Consider the operating pressure, flow requirements, and control needs of the pipeline forming machine, ensuring the pump can handle peak loads during bending operations.
• Ensure compatibility with the machine’s prime mover (electric motor or engine) in terms of speed and power, selecting the correct drive type (direct flange, long shaft, or extended shaft).
• Choose the right control type (pressure compensator, load sensing, or electro-hydraulic proportional) to optimize energy efficiency and pipe forming accuracy.
• Verify the pump’s mounting configuration matches the machine’s hydraulic power unit design, ensuring proper alignment and reducing vibration.
• Consider the environmental conditions (temperature, dust, moisture) to select appropriate seals and protection features, especially for outdoor pipeline construction applications.
• Ensure proper hydraulic fluid selection and maintenance to maximize pump service life and reliability, using anti-wear hydraulic oil (ISO VG 32-68) with NAS 6 or higher cleanliness rating.
• Follow Vickers’ installation guidelines and maintenance procedures for safe and efficient operation, including regular inspection of pressure, temperature, and noise levels during pipeline forming operations.
• Use only genuine Vickers replacement parts to maintain performance and reliability; non-genuine parts may cause reduced efficiency and premature failure, leading to inconsistent pipe forming quality.
• Do not disassemble the pump without authorization; consult Vickers technical manual or professional maintenance personnel for service, ensuring compliance with safety standards in pipeline forming facilities.
