140mm PVC Casing Pipes are a type of polyvinyl chloride (PVC) pipe with a nominal diameter of 140 millimeters, designed specifically for use as casing in various underground applications. They are typically made from rigid PVC, a durable thermoplastic material known for its resistance to corrosion, chemicals, and impact. These are typically installed by trenching or directional drilling methods, depending on the project requirements and soil conditions. They offer long-term protection and support for the utilities or piping systems they encase. 140mm PVC Casing Pipes are designed to withstand the rigors of underground installations, including soil pressure, ground movement, and environmental exposure.
