Flaring Tools

Flaring Choices for PFA, PEP, PTFE Tubing

In the early 1970s, when PFA & PTFE flare fittings were introduced, a cold plier that stretched the tubing outward was the only available tool for expanding the tube end to fit over the flare nozzle on the fitting. However, this method was crude and placed undue stress on both the tube and the flare joint, as the tubing would often shrink back to its original size shortly after stretching. This issue, combined with thermal and pressure cycling in applications, often led to eventual leaks in the joints.

PFA Fusion Welded Pipe & Tubing Manifolds

Advanced Fusion Welding Equipment for Seamless Pipe Integration

Crist Group has developed proprietary fusion welding equipment that facilitates tube and pipe weldments ranging from 1/16″ to 3″, enabling side fusion welding to tank or piping walls. This approach eliminates excess fittings, ensures full pressure capability, and streamlines systems. Additionally, the equipment allows for angular fitting welds, enabling custom configurations like custom angle elbows and WYE pattern fittings.
