151-Series High Lift Flange Test & Welding Plugs Operating Instructions

These plugs have a Urethane seal.

  • Fast, easy installation, and testing.
  • Segmented compression tube allows adjustment of seal installation depth.
  • Faster pipe repairs and retrofits.
  • Improved Seal-to-Pipe Clearance: Plug can be easily installed and removed, even where there is severe weld protrusion.
  • Low water requirements resulting in less waste water.
  • A minimum of 1.5:1 safety factor.
  • Rugged, heavy-duty construction.
  • Versatile: Seal and washer sets easily change to accommodate different pipe schedules.
  • Ported Center Shaft: Permits monitoring of downstream pressure of inert gas rejection.
  • Flange classes 150 - 600 lbs.
  • Seal Materials: Urethane Standard.

* Seal-to-pipe clearance: approximately 1/2". Clearance may be slightly smaller on plugs that accommodate more than one schedule size.  Replacement washers:  required on all schedule sizes except for the smallest ID for each size pipe.

** External O-ring:  included on 10" and 12" seals.

Other flange class ratings and pipe schedules available upon request.  Call for pricing.

Ordering information needed:  flange size and rating, pipe ID or schedule, and test pressure.

*Mechanical Plug Warning: Maximum head pressures that a pipe plug may hold back can only be estimated. Pressures are influenced by many factors including fluid and debris in the pipeline, type and condition of pipe, tightness of plug seal, and temperature. Plugs should always be inserted fully into pipeline and should be mechanically blocked when slippage could cause property damage or injury. NEVER use a test pressure greater than the capacity of the weakest pipe or component in the system. NEVER use a mechanical plug when its failure could cause injury.
