Whether the bellows contain steel wire depends on its specific type and purpose. Here is a detailed analysis:
Corrugated pipe without steel wire
The core part of the bellows is usually made of thin-walled stainless steel or other metal materials, and the shape is continuous corrugation, which is mainly used to adapt to displacement changes in the pipeline system, such as thermal expansion and contraction or equipment vibration. This kind of bellows does not contain steel wire, but relies on the corrugated design to achieve elasticity and elasticity.
Corrugated pipe with steel wire
Some bellows are wrapped with a mesh sleeve woven with steel wire on the outside, which is called a steel belt reinforced bellows. The main function of the mesh sleeve is to enhance the compressive capacity of the bellows and protect the bellows from damage by external impact or tensile force. For example, HDPE steel belt reinforced polyethylene spiral corrugated pipe is a typical steel wire corrugated pipe, which is reinforced with "V"-shaped steel belt instead of ordinary steel wire.
Application scenario determines whether to have steel wire
Corrugated pipe without steel wire is suitable for general pipeline systems, such as pressure measuring elements in instruments and meters.
Corrugated pipes with steel wires are used in scenarios that require higher pressure resistance and durability, such as underground drainage systems or industrial pipes.
Summary: Whether the corrugated pipe contains steel wires depends on its design and purpose. Ordinary corrugated pipes usually do not contain steel wires, while reinforced corrugated pipes may contain steel wires or steel strips to improve performance.
