Expansion Springs made by us are used in conjunction with stainless steel banding and stainless steel wing seals also referred to as breather springs or chil springs. By affixing to the banding they allow the banding to expand and contract where required. These are widely used over metal jacketing for oil and gas pipework. We can also supply compression springs also often referred to as mighty springs or mity springs commonly used for large diameter pipework, tanks and vessels.
