Guidelines for Correct Tube Expansion The basic purpose of tube expansion systems is to obtain a good hydraulic and mechanical joint. A secondary, but equally important, purpose is to obtain a seal that is durable, resistant to corrosion and essentially free of longitudinal stress. During tube expansion we must take care of ‘over expansion’ and we […]

Bolt-tightening Methods Without a doubt, bolted assemblies are the most commonly used joints in mechanics. These types of assemblies employ two basic elements: on the one hand, some kind of threaded component: – screws and nuts, – studs with nuts on one end, – studs with nuts on both ends. These components are sometimes used […]
