Titanium Stub End

Titanium stub end is generally used in conjunction with stainless steel or carbon steel flanges to reduce usage costs. This type of flange is also known as looped flange (PJ/SE), looped flange or loose flange.

Titanium stub end, also known as titanium butt welding ring, is used by threading the titanium stub end into the stainless steel flange. The titanium stub end is welded to the pipeline (titanium pipe pipeline), and the two welded titanium stub end are docked, and the stainless steel flange is tightened. The area in contact with the medium in the pipeline is made of titanium material, which means that the original titanium pipe pipeline is contacted with titanium stub end, while the stainless steel flange part is not in contact with the medium and only serves as a fastening effect, greatly reducing costs.
