A drainage pipe is designed to carry away water or waste fluids, typically with perforations or openings along its length to allow water to enter.

Solid wall pipes are commonly used for pressurized systems such as water supply or sewage lines. **

The scratching in the wall pipe can be caused by a few different factors. One common cause is the buildup of mineral deposits or sediment inside the pipe, which can create rough surfaces that cause scratching as water flows through. Another possible cause is the presence of debris or foreign objects in the pipe, which can rub against the walls and create scratching. Additionally, if the pipe is old or corroded, the metal surface may become rough and lead to scratching as well. Regular maintenance and inspection of the pipes can help identify and address these issues before they become more serious. **
