Vertical Base Mounted Unit for Installation Beneath Pipe (QC150)

The Vertical Base Mounted Unit is engineered for secure support beneath pipework subject to vertical displacement due to thermal expansion or movement. This unit features a constant load mechanism, counterbalanced via a cranked load arm, to ensure uniform support throughout the travel range. Constructed from durable carbon steel with options for stainless steel, it is designed for both standard and customized applications, capable of supporting hydrostatic test loads up to twice the operating load.

Spec Sheet

Quality Pipe Supports (QPS) Ltd. Constant Spring Units provide consistent support for pipework experiencing vertical expansion or contraction. By maintaining a constant load throughout the unit’s travel range, these supports prevent undue stress on pipe connections, ensuring system integrity.

Key Features

  • Constant load maintained across full range of movement.
  • Load adjustment capability of ±20% via adjustment screw.
  • Individually calibrated using electronic load-travel recording.
  • Durable construction with stainless steel scale plates for precise support details.
  • Options for hot-dip galvanising or multi-coat paint systems.
  • Available in carbon steel, with stainless steel options for corrosive environments.

Design and Construction

Constant Spring Units employ a cranked load arm and coiled compression spring, perfectly counterbalancing pipe loads based on the principle of moments. Robustly built, with casing protection against environmental conditions, they feature versatile attachment options for steelwork connection.

Model Range

Six models – horizontal, vertical, and base-mounted – are offered in 66 sizes, supporting loads from 10kg to 31,500kg and accommodating travel ranges from 40mm to 610mm. Custom designs for extended loads and travel are available.

Preset and Testing

Units are pre-set for cold conditions with removable locking pins for easy installation. They support hydrostatic test loads up to twice the operating load, ensuring reliability under demanding conditions.
