Jolly Clamps

The output provided by a product in relation to the input invested determines its performance. Many OEMs and end-users of hose clamps believe that the input torque delivered to the clamp is a measure of the clamp's performance, however, this is not the case. Today, through this blog we will debunk some of the fallacies around clamp performance and losses. 1. How a worm drive hose clamp works When torque is applied to the screw engaged in the strip, the threads pull the strip against the housing, resulting in an effective clamp joint. A multitude of intricate events happens during this action. The imparted torque is first transformed to effective tensile force, which is stored as strain energy, and then to heat energy owing to frictional losses of mating components. This strain energy is the potential energy stored in the band as a result of its elastic deformation. And it is this strain energy that causes the micro elongation of the band, which can be determined from the area unde...

A lot of times hose clamps leak even after applying proper installation torque, and people become weary of trying to figure out the core cause of the problem and end up overtightening the clamp as a remedy. This post shall shed some light on a much obscure and frequently taboo issue, the source of these mysterious leaks- the Cold Flow or Cold Leaks. 1. Cold Leaks The hose is constructed of elastomer (rubber), which has a terrible propensity for deformation, which is reflected in the phrase Compression set (C-set). The compression set is a measurement of how well a material can return to its original shape after being squeezed by a force. An ideal compressive strength is defined as a material that recovers to its original thickness. When a hose clamp is tightened on a hose, it attempts to replicate the sort of indent (impression) created by the clamp band. The clamp is presently tightened in one shot once the torque is applied, and the hose is not given enough time to go into motio...

Fixing a hose clamp is not as simple as tightening a simple bolt. From a normal perspective, this procedure appears to be fairly straightforward, but it entails a sequence of complex processes that are frequently neglected by the companies and end-users, resulting in the undervaluation of a clamp's capabilities and unwanted leak difficulties. Through this blog, we will attempt to grasp the proper manner of tightening a hose clamp as well as crucial considerations to remember when doing so. 1. Installing the Torque Torque is usually suggested by the standard manufacturer for clamp installation. Application torque is another name for installation torque. To create an effective hose junction, the proper amount of torque must be applied. The crucial aspect to remember is that clamp performance is determined by the clamp's actual clamping force (expressed as either Band tension or Radial load) rather than the torque applied. Excessive application torque may result in irreversible ...
