It is a common knowledge that many of the supplies, including those that are kept in stocks, are designed to be stored in strict accordance with manufacturer’s requirements. Follow this practice is crucial, because we know that if we neglect storing conditions of milk it is likely that it will spoil quickly. Unfortunately, most gaskets for flanges compound are seldom kept under optimal or at least satisfactory conditions – at first glance non-significant aspect results in thousands of dollars wasted.
So what is the best way to store gaskets and how can the conditions of their storage be improved? Let’s consider the experience of Alexandercomley Company, one of the largest flanges manufacturers in the United Kingdom providing triple A class flanges solutions.
Gaskets are widely recommended to be stored in oval and cool dry place away from heat, moisture, direct sunlight and chemicals. The optimal storage conditions include a temperature range from 5° to 25°C at a relative humidity of 40-75%, in a room without windows or with low levels of ultraviolet radiation, minimal dust content and the absence of chemicals, stored nearby.
So where to find such facilities in modern production? Warehouses, which store lining, are often located next to the front doors, lit with fluorescent lamps, and undergoing frequent fluctuations in temperature and humidity. Heavy metal shims ‘Armco’ are usually dumped on the shelves in the soft rubber pads, hanging on hooks attached to the wall. The sheet material is sometimes stored in a horizontal position in the open air, in a vertical position along the wall or in a partially collapsed form in the corners.
There are many reasons to follow the rules of proper gasket storage. The summary of them is that in most cases it is a problem with gaskets causes leaks of flanged joints. Nevertheless, before blaming gasket one must give it a chance to save the physical properties before it is installed.
Gaskets with rubber components
Flexible gaskets oftentimes represent complex products, made of a variety of materials. Thus, 15-20 components should ideally interact with each other to ensure the excellent quality of the final product. The key components include rubber binder, reinforcing fibers and a filler.
It’s not a secret that the tire loses its properties relatively quickly. That is why the slightest change in the storage conditions directly affects the lifespan of rubber oval gaskets. Most pads are not intended for long term storage, even under thorough conditions previously described. Elastic chemicals used in the manufacture of rubber gaskets are selected basing on the optimum technological conditions in the production, as well as maximum efficiency when working as part of the connection flanges. Creating additional facilities for storage may be a too pricey solution, this is why production specialists should pay close attention to the environmental conditions.
Minimize dust, temperature fluctuations, UV and chemical fumes. If you slice the gasket from a sheet, do not store them in limbo, so they are not stretched. Put them on a shelf, if possible. Fold the remainder of the sheet material and pack in opaque heavy paper or cardboard. Place the roll so that it is not bent.
