The RED IRON RESTRAINT system is designed to help contain high-pressure piping and components in case of rupture during the pumping process. The destructive force of an unrestrained flow line rupture, regardless of the cause, can be devastating and catastrophic to both people and equipment.

Installation of the RED IRON RESTRAINT system can help producers and well service providers deliver on a commitment to safety at the well site. The RED IRON RESTRAINT system utilizes half-hitches on each side the hammer unions running the full length of the flow line. The system is anchored at each end giving 100% security.

Hobble Clamps are used to secure ends of high pressure hydraulic hoses, and guard against accidents in the event of failure at the hose connection.

The WHIP STOP has a specially designed braided cable which allows the cable to tighten down on the hose during a failure. Unlike the WHIP CHECK or the Hobble Clamp, the WHIP STOP will continue tightening down. The double leg anchoring points prevent the hose from whipping side to side making the WHIP STOP very desirable where employees are work near high pressure applications.

The CABLE CHOKER has a specially designed nylon spool which allows the cable to tighten down on the hose during a failure. Unlike the Whip Check or the Hobble Clamp, the CABLE CHOKER will continue tightening down sometimes even choking off the air for a more controlled release.

If a hose fails at the fitting area Whip Checks or Whip Stops, are designed to give limited protection from hose whipping. The Whip Check will work on hoses ranging in size from ½ I.D. to 4 I.D. and only should be used on hoses with a maximum pressure of 200 PSI.
