Product Description

Our corrugated tube is a type of pressure-sensitive elastic element widely used in pressure measurement instruments. It consists of a cylindrical thin-walled shell with multiple transverse corrugations, allowing it to produce displacement when subjected to pressure, axial force, lateral force, or torsion. Corrugated tubes are widely used in various instruments and devices, serving as a measurement element to convert pressure into displacement or force. With its thin-walled structure and high sensitivity, it can measure pressure ranging from several pascals to tens of megapascals. Additionally, corrugated tubes can also be used as sealing isolation components to separate two media or prevent harmful fluids from entering the measuring part of the equipment. They can be used as compensation elements to compensate for temperature errors in instruments by utilizing the variable volume of the tube. It can also be used as an elastic joint between two parts. Depending on the materials used, corrugated tubes can be classified into metallic and non-metallic types, and according to their structure, they can be classified into single-layer and multi-layer types. Single-layer corrugated tubes are commonly used, while multi-layer types are utilized in critical measurements due to their high strength, durability, and low stress.
