Safety Features

✔ No flying metal chips
✔ No equipment overtightening and hammer misuse
✔ Personnel stay out of the liquid spray zone by using the long moment arm

Technical Aspects

✔ Equal torque application ensures proper seal on connections
✔ Can, on average, be supplied with 18% more torque compared to the conventional hammer unions (1240 lbs – ft vs. 1052 lbs – ft)
✔ Increases accessibility, with 8 points located every 45° due to its unique design and can be handled by a single crew member

Savings

✔ Since a hammer strike is not used, the cracking of the nut due to fatigue is greatly reduced
✔ SaferUnion™ Nut is 100% compatible with existing products, reducing the cost of moving to the new technology
✔ Saves time during the rig up/rig down processes by eliminating the need to take off and putting back the pressure gauges, electronic pressure gauges and other gauges, which come loose due to vibration caused by a sledgehammer

Quality Features

✔ SaferUnion™ is compliant with API Recommended Practice 7HU1
✔ API Q1 compliant processes used by RH Machine ensure high quality and reliability of the tool
✔ Traceability provides an extra measure of quality control to increase the tool safety and reliability

Other features

✔ No special PPE required
✔ Anticorrosion coating is available upon customer request
✔ Installation or disconnect is an intuitive, understandable procedure

About

The SaferUnion™ is a superior alternative to the conventional hammer unions that provides greater safety in dangerous working environments. It requires the use of less energy. Instead of hitting a union with a sledgehammer to tighten the connection, the new design uses a bar with a long moment arm, that is capable of providing sufficient torque on the nut to either tighten or loosen the connection.
