The wall thickness of Propane-Propylene (PP) Splitter plays a crucial role in its external welding process.

Thicker wall thickness will bring certain challenges to welding. First, more heat input is required to ensure sufficient penetration to achieve a good weld connection during welding. This may increase the difficulty and time cost of welding, and require more precise welding process control to avoid overheating that may cause damage to material properties or welding defects.

However, thick walls also have their advantages. It can provide better structural strength and stability, and can withstand greater external forces and pressures after welding. At the same time, thick walls can reduce the risk of welding deformation, so that the welded parts maintain good shape and dimensional accuracy.

On the contrary, thinner wall thickness is relatively easier to weld, with lower heat input requirements and faster welding speeds. However, thin walls are more prone to deformation problems during welding, which may affect the accuracy and performance of the entire component. Moreover, its strength when subjected to external forces may be relatively weak, requiring special consideration in design and welding process.

The wall thickness of the Propane-Propylene (PP) Splitter also affects the residual stress distribution of welding. Thick walls may cause greater residual stress, which may cause some potential problems in subsequent use, such as crack generation and expansion. The residual stress of thin walls is relatively small, but it is also necessary to pay attention to its impact on the long-term performance of the components.
