S.T.A.M.P
. When you're specifying a gasket for even the most basic application, it is very important that the gasket provider know all the operating parameters.
There are five major pieces of information required to select the appropriate gasket, known by the acronym S.T.A.M.P.:
While gaskets are usually used in standard ANSI flange connections, non-standard flanges can also be discovered throughout a plant. In dealing with non-standard flanges, it is EXTREMELY essential to get as much detail as possible about the contact measurements (the portion of the gasket in fact being compressed) and the fasteners or bolts being utilized (size, grade, quantity). This information is used to calculate the contact area and available assembly tension-- a key consider the choice process, as an incorrectly packed gasket might result in premature equipment failure.
Temperature level:
While numerous systems run at a continuous temperature level, or within a standard range, it is necessary to call-out any system temperature spikes, as well as thermal cycling, if they exist. When a system temperature level fluctuates or cycles, the gasket must react to movements in the application related to growth, contraction, and modification in internal pressure.
Application:
Application is similar to size, because it relates to the devices where the gasket is being used, but unlike size, application data might contain additional information that would not be covered by basic Gasket -Flange Connectionsdimensional info. Such as the end-use and devices where the gasket is being set up. Application-related questions need to be solutioned to aid in the choice of the product.
Media:
The fluid or gas the gasket is sealing in, or out, of an assembly. When selecting an item to seal a particular media, it is very important to consider not only chemical compatibility however likewise emissions compliance. For example, a gasket might work extremely well for sealing liquids, but might not offer the required level of permeation resistance for certain gases.
Pressure:
Many systems operate at a "continuous" pressure, nevertheless, if system upsets occur, it is very important to element that into the selection process. Some examples are:
Rising-- When system pressures are significantly increased over a brief amount of time.
Hammering-- Commonly produced when valves are shut too rapidly. Media flowing through a pipeline has inertia, and when valves shut too quickly, the system must take in the inertia of the media. The weakest point in the assemble is generally the gasket.
Thermal Expansion-- When a liquid is heated up in an enclosed space, without any air area for growth, the internal pressure that is generated can be disastrous to the system, devices, or sealing gadget (gasket) in the system.
