Small diameter plastic tubing

Types of Small Diameter Plastic Tubing

Small diameter plastic tubing is a thin-walled tube made of plastic material with a small diameter. It is lightweight, offers excellent corrosion resistance, and has a smooth inner surface, making it ideal for applications in various industries. Small plastic tubes are used in hydraulic and pneumatic systems, medical devices, fluid transfer, and more.

Small-diameter plastic tubing is manufactured using different methods and comes in various types. Each type is designed for specific applications and industries. The types include:

• Extruded Plastic Tubing

  This is the most common type of small-diameter plastic tubing. It is manufactured through a continuous process known as extrusion, where plastic resin is melted and forced through a die to create a tube shape. The extruded tubing is then cooled, cut to the desired length, and ready for use. This type of tubing is popular because it is cost-effective and has consistent diameter and wall thickness. Commonly used materials for extruded plastic tubing include PVC, polyethylene, and polypropylene. Applications where extruded plastic tubing is used include wire and cable insulation, medical packaging, and consumer goods.

• Injection Molded Tubes

  These tubes are created using injection molding, a process where molten plastic is injected into a mold to take the desired shape. This type of small-diameter plastic tubing allows for complex shapes and designs with high precision and strength. Injection molded tubes have thicker walls and are more robust than extruded tubes. They are made from engineering-grade plastics such as nylon, acrylic, and ABS. Injection molded tubes are used in applications that require high strength and durability, like automotive components and industrial machinery.

• Vacuum-formed Tubing

  This type of small-diameter plastic tubing is produced by heating a plastic sheet until soft and then forming it over a mold using vacuum pressure. It is ideal for applications where non-circular or complex shapes are needed. Vacuum-formed tubing is lightweight and cost-effective for low-volume production. It is made from materials such as polystyrene, acrylic, and PETG. Applications include signage, lighting covers, and custom enclosures.

• Spiral Wrapped Tubing

  The spiral-wrapped small-diameter plastic tubing is made by wrapping a thin strip of plastic around a mandrel in a spiral fashion. It is flexible and can be bent around corners and obstacles without breaking. This type of tubing is used to protect wires and cables from abrasion and environmental damage in tight spaces and complex routing. It is made from materials like PVC, nylon, and polypropylene. Applications include cable management, automotive wiring harnesses, and aerospace wiring.

Function and feature of small diameter plastic tubing

• Small diameter plastic tubing is flexible

  Small plastic tubing is flexible, especially when made from materials like polyethylene or PVC. This flexibility allows the small tubes to bend around corners or obstacles without breaking, making them ideal for applications where rigid tubes would be challenging to install. Their flexibility improves flow capacity in plumbing systems by reducing kinks and sharp bends that restrict water flow. Flexible small-diameter tubes are easier to install and reposition in tight spaces or complex layouts, saving time and reducing the risk of damaged tubing.

• Small-diameter plastic tubing light weight

  Small plastic tubes are lightweight, making them easy to handle and transport. This reduced shipping cost is beneficial for large projects. Their lightweight enables the construction of lighter assemblies and products, reducing overall weight. For example, in the automotive and aerospace industries, using lightweight small-diameter plastic tubing can improve fuel efficiency and enhance vehicle performance.
