Plastic pipes, tubes, and rods are versatile materials used in construction, DIY projects, and industrial applications. Pipes are typically rigid or flexible hollow cylinders, made from materials like PVC, CPVC, or HDPE, and are commonly used for plumbing, drainage, and gas transport. Tubes, often made of acrylic, PETG, or silicone, are lightweight and used for fluid transfer, lighting diffusers, and protective sleeves. Rods, solid and sturdy, are crafted from nylon, polycarbonate, or Delrin and serve as structural supports, machine parts, or craft materials. Pipes are measured by inner diameter (ID) and pressure rating, tubes by outer diameter (OD) and wall thickness, and rods by diameter and length. Each type offers unique properties like flexibility, transparency, or chemical resistance, making them suitable for a wide range of uses.
