气管的主要用途，是将压缩空气输送到各个使用点。适合使用哪种气管，取决于应用领域和个别要求。很重要的一点是，定期维护气管可有效避免产品缺陷，防止影响气动应用的使用寿命和功能性。Festo 气管在满足标准要求的同时，还能可靠地耐受各种极端条件，比如高温、焊接飞溅、高 pH 值、耐加水分解等。
今天的气动系统默认采用经过外部校准的气管。它们适用于所有现代化螺纹连接，比如 QS、NPQM（用作插拔式轴套）、NPQH 等。经过外部校准的气管，以产品外径作为气管规格参数。除此之外，还有经过内部校准的气管，这类气管以内径作为气管规格参数。在快插式接头面世之前，这些都是气动系统的标准配置。您可以找到适用于所有早期常见螺纹连接的内部校准型气管，比如 CK、CN、PK 等。使用不同的工作长度和拉伸载荷工作时，螺旋气管是首选 - 尤其在与气动工具组合使用时，螺旋气管可为应用提供正确的附件。在外部和内部校准型气管以及螺旋气管方面，Festo 为您提供直径、材料选择范围广泛的诸多产品款型。此外，您还可以在 Festo 找到与您的气管相匹配的附件。
The material of a pneumatic tube should be suitable for the individual requirements. Here are some individual materials and their characteristics:
Pneumatic tubing made of polyurethane (or PU) is the first choice when pneumatic control systems have to be connected. It is available in numerous sizes and is characterised by its flexibility and small bending radii. PU pneumatic tubing is available in many different colours, which is practical for keeping track of the individual lines when installing tubing for complex control systems. It meets numerous requirements thanks to its different special properties: they are spatter-proof, flame-retardant and electrically conductive.
Compared to PU tubes, those made of polyamide (or PA), are more temperature-resistant and thus more pressure-resistant. As a result, the tubing material is stronger and therefore less flexible since polyamide is semi-rigid and kink-resistant. PA tubing is generally completely pressure-resistant at a temperature range of -50°C to +20°C (decreasing thereafter as the temperature rises) and is therefore ideally suited for use as compressed air lines as well as compressed air brake lines.
Pneumatic tubing is made of polyethylene (or PE), is very light, resistant to impacts and largely resistant to acids, alkalis and salt solutions. PE tubing is suitable for use in a temperature range from -30°C to +80°C and is the most cost-effective variant of all pneumatic tubes.
Pneumatic tubing PTFE / PTFA / PFA is suitable for extreme temperature ranges from -20°C to +150°C. It fits with all common connector types and is available as standard in natural colours and as CS type in green and red. PFA tubes can also be welded.
Which of the Festo pneumatic tubes is the right one for you depends entirely on your requirements. Our product range includes tubes of different diameters, lengths, colours and materials. Regardless of whether the tube has to meet standard requirements or extreme conditions such as high temperatures or changeable weather conditions, at Festo you will find a suitable tube for every industry.
