What is plastic corrugated tubing? Simply put, it is a foldable, telescopic plastic component widely used in the instrumentation industry. Below, we’ll break down its key applications and classifications.
Main Applications
During operation, pressure inside the corrugated tube builds gradually along its length, causing the movable end to shift in direct response to pressure changes. The pointer on the movable end can directly display pressure values. It is usually paired with other sensors to act as a pressure transducer, or can also be used independently as a standalone pressure-sensing element.
The primary role of plastic corrugated tubing is as a core component in pressure measuring instruments, converting pressure into displacement or mechanical force. Despite its thin wall, this corrugated tubing delivers high sensitivity and a broad measurement range of up to 10 MPa. One open end is fixed, while the other remains free during sealing. Auxiliary coil springs or reeds can be added to further enhance its elasticity.
Common Classifications
Plastic corrugated products are mainly divided into two categories:
- Hermetically sealed corrugated pipe: Fully airtight and watertight, it is applicable for fluid delivery in thermal power plants, gas water heaters and other industrial equipment.
- Continuous-wound corrugated conduit: Specifically designed for electrical cable protection, such as telephone and power cables routing.
This is a brief overview of plastic corrugated tubing, clarifying its core applications and functions for practical use. When purchasing, be sure to choose professional industrial suppliers — avoid low-quality, low-cost products to prevent performance issues in subsequent applications.
