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.

Introduction

A Titanium stub end is a specialized piping component used in flanged connections, designed to facilitate the assembly and maintenance of pipeline systems. It is typically paired with a lap joint flange and serves as a short, flanged segment welded to the end of a pipe. This configuration allows for easy alignment and disassembly of flange joints, particularly in systems requiring frequent inspection or modifications.

Applications:

Chemical Processing: Resistant to corrosive media like acids, alkalis, and chlorine.
Oil & Gas/Offshore: Performs well in sour service (H₂S environments) and seawater-cooled systems.
Power Generation: Withstands high-temperature steam and cooling systems.
Pharmaceutical/Medical: Ideal for ultra-clean or sterile processes due to non-reactivity.

Attentions

Titanium stub end can only be welded with titanium pipes, using argon arc welding, and using titanium wires made of materials similar to titanium flanges. It is not allowed to directly weld with stainless steel pipes or other materials of pipelines. Do not use in high pressure pipeline environments.
