ERW Pipes With Roll Grooved Ends

The only system that provides the option of rigidity or flexibility.

Roll grooved* end pipes that have many advantages. It is the most versatile, economical and reliable piping system available. It is faster to install than welding, easier and more reliable than threading or flanging, generally resulting in the lowest total installation cost.

*Black and galvanized pipes are processed with grooved ends.

Grooved End Piping System is used in various fields and sectors:

  *  Fire Installations (sprinklers)

  *  Automotive

  *  Chemistry

  *  Installation systems

  *  Air conditioning

  *  Dredging

  *  Mining

  *  Ship Building

  *  Textile

  *  Irrigation and sewage systems

Rigidity:  Versatility is the key, utilizing standard grooved pipe, fittings and valves, rigidity can be achieved with standard couplings. The couplings provide positive clamping of the pipe to torsional and flexural loads.

Noise and Vibration Attenuation:  The basic design of independent grooved pipes, sealed by a rubber gasket and unified by an externally belted coupling housing, reduces noise / vibration transmission providing superior vibration attenuation throughout the pipe system.

Easy System or Equipment Access: Removal of two couplings ( just four bolts) provides access for cleaning, maintenance, system expansion and changes.

Flexibility: The grooved system accommodates expansion / contraction / deflection and permits pipe systems to be designed to take advantage of these characteristics. Elimination or reduction of special vibration accessories, expansion loops, and settlement allowance are among the design options.
Seismic Stress Absorption: The full engagement of the housing keys into grooves around the full pipe circumference provides significant pressure restraint and end-load capabilities to withstand pipe movement from internal and external sources.

Easy Alignment: The grooved system allows full rotation of pipe, valves, fittings or couplings before tightening for easy alignment. This compensates for some alignment errors and eliminates the ‘‘two-holing’’ required with flanges. Plus, the system facilitates placement in tight spaces.
