Cold Shrinking Ln2 Nitrogen Gas

Creating high-strength metal joints without compromising on quality or reworking: cold stretching is a simple and proven process for joining components together with a positive fit and in a short space of time. This technology is based on the physical law that metals contract – “shrink” – at cold temperatures. If the components are then reheated, they expand and thus create a firm hold. The advantages of cold stretching – also known as cold shrinking – are obvious:

• Low labor and energy costs
• Applicable almost everywhere
• No loss of quality
• Precisely fitting and firm connections
• Can be combined with heat treatment

The optimum equipment

Liquid nitrogen is suitable for achieving the low temperature required for cold stretching. Suitable, high-quality and certified equipment is mandatory when handling liquefied gas. We offer you a range of high-quality products in series production, but also accessories manufactured specifically to your specifications for your area of application.
