Are there any components similar to elastic bands that can be used as spring supports?

The idea you mentioned is very interesting! Indeed, the spring supports used in pipeline engineering these days (especially those for horizontal pipelines) are mostly of the coil spring type; they are large in size, take up a lot of space, and are difficult to install. The “elastic band” solution you’re thinking of seems more flexible and space-saving at first glance. This type of \"elastic band spring support\" is indeed not common in the standard industrial sector. The main reason for this is not so much a material issue, but rather several more fundamental engineering constraints: ### 1. **The conflict between stress and displacement** – The primary function of a spring support is to provide **controlled, stable support** when pipes expand or contract due to temperature changes, while still allowing the pipes to move in certain directions. - The force-displacement relationship of elastic bands (such as rubber bands, polyurethane bands, or metal leaf springs) is usually **non-linear**: they are soft at first, but become suddenly stiffer as the displacement increases. This characteristic is dangerous in pipeline support systems – as the temperature changes, the supporting force varies significantly, which can lead to uneven stress on the pipelines, excessive stress at the connection points, and even failure of the supports themselves. - Spiral springs can achieve an **approximately linear force-displacement curve** through design considerations such as spring stiffness and pre-compression, allowing the supporting force to change smoothly with displacement – which is crucial for protecting pipeline systems. ### 2. **Durability and reliability issues** – Pipeline systems typically require supports with a lifespan of over 20 years, and they must be able to withstand harsh conditions such as high temperatures, humidity, and vibration. - Elastic bands (especially those made of polymer materials) are prone to **aging, fatigue, and creep** (slow deformation under prolonged stress). The support height adjusted today may become ineffective in a few months due to material relaxation, causing the pipes to sink. - Metal leaf springs (similar to truck leaf springs) are more durable, but they generally provide only unidirectional flexibility; they find it difficult to accommodate complex displacements in multiple directions of the pipeline, and they are prone to fatigue fracture due to repeated deformation. ### 3. **Lack of engineering standardization and safety regulations** – Existing pipeline stress analysis software and design standards (such as ASME B31.1, GB/T 17116) are all based on performance data of traditional spring/constant-force hangers for their calculations. - Elastic bands lack **standard mechanical performance parameters** (such as stiffness curves and fatigue life data), preventing engineers from conducting reliable calculations, and they will not be accepted by supervisors and inspectors. Without standards, there is no foundation for large-scale application. ### 4. **Hidden challenges in actual installation and maintenance** – Elastic bands require **precise pre-tensioning and tensioning**, and it is difficult to set the pre-pressure during installation using simple thread adjustments like those with coil springs. - It does not have a **self-locking or anti-loosening mechanism**, and it tends to loosen under prolonged vibration. - Inspection and maintenance are also troublesome: to check whether the coil spring has failed, one just needs to look at the scale label ； It is however difficult to visually determine the degree of aging of elastic bands. ### So, are there any alternatives that come close to what you had in mind? In fact, in some **non-standard, low-displacement, or temporary applications**, components based on similar principles are used: – **Polyurethane shock absorbers/pads**: These are used to absorb high-frequency vibrations, but they are not typically used as the primary support. - **Metal Buckling Plate: In a few special designs, thin steel plates are used to undergo buckling deformation in order to provide elasticity, although the amount of displacement is very small. - **Constant-force spring (coiled spring): Such as the kind used in roller shutters, but it has a limited load-bearing capacity and is not suitable for heavy-duty pipes. ### To sum up: “Elastic bands” have not become mainstream; **the key issues are engineering reliability, controllable stress, and standardization, with material being just one aspect of it**. Although helical springs are bulky, their predictable mechanical properties, long service life, and compatibility with existing design systems are advantages that are difficult to replace when it comes to industrial safety. However, your idea does highlight the shortcomings of existing spring brackets – **in the future, if high-performance composite materials become available (such as creep-resistant flexible metal composites that allow for precise control of stiffness and are resistant to aging), then such flexible brackets might have a chance to succeed**. But until then, engineers will likely continue to deal with these traditional springs that are both tall and difficult to install. .

Until useful elastic band products become available, this flat spring bracket described here remains practical. https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=5702028
