Basic introduction to lead pipes

Good corrosion resistance, can resist sulfur dioxide, 60% hydrofluoric acid, acetic acid with a concentration of less than 80% and 15%~65% sulfuric acid corrosion. The maximum allowable temperature is 140°C. Not resistant to corrosion by concentrated hydrochloric acid, nitric acid, hypochlorous acid, potassium permanganate, etc. It can also be used for radiation shielding on medical equipment and radiation shielding in nuclear materials.

Lead pipes are divided into pure lead pipes and alloy lead pipes. Pure lead pipes have also become soft lead pipes with grades of Pb2 and Pb3. Alloy lead pipes are also called hard lead pipes, and the commonly used grades are PbSb0.5, PbSb2, PbSb4, etc.

Lead pipes are easily rolled, forged or welded. However, it is soft in nature, poor in mechanical strength, high in density, and low in thermal conductivity. If necessary, steel pipe armor should be used to increase its compressive capacity. When installing, it should be installed in a wooden groove, or placed in a groove made of a split steel pipe or angle steel to prevent it from deforming and sagging.

It is widely used in the sulfuric acid industry and the organic industry dealing with acidic materials.
