Importance of Tri Clamp and Tightening Torque Management

When we're trying to “tighten” something, we tend to think about fixing the object so that it cannot move at all.

However, “tight screwing” does not necessarily mean “secure tightening. ” It is important to tighten with appropriate torque. Excessive tightening may cause deformation or breakage of parts.

Also, the user should be careful about the protrusion of the gasket due to excessive tightening. The gasket between the piping or between the lid and the container may protrude into or out of the container or piping, resulting in poor sealing performance and contamination.

In this article, we will focus on the inside protrusion of the ferrule gasket. When the ferrule was tightened with a clamp, we experimented on how much the gasket protrudes due to the tightening torque.

Useful Tips, Flexible/Fixed Casters Mounting Location

A stainless steel container is heavier than a resin container. If the container contains contents or is made to withstand pressure, it will be much heavier.
In such stainless containers, it is common to move by using a cart or attaching caster legs.

But isn't it a little irritating when casters don't move the way you want them to?
In fact, there are several different types of casters on the basis of their movement, and the workability can be improved greatly by selecting them according to different usages.

This article explains the combination and arrangement of “Flexible Casters” and “Fixed Casters” among various types of casters according to the usage.

  • 2 different types of casters: flexible casters and fixed casters
  • Things you need to consider to choose casters appropriately: mobility, convenience of going straight,  weight of objects to be carried
