More and more users are specifying high-performance alloys and metals - for purposes such as minimizing the risks from corrosion damage and extending the lifecycles of processing equipment in harsh environments.
Heat Code Traceability (HCT)
One of the most useful tools that end users have at their disposal is any 3.1 material inspection certification for the raw materials, which can be accessed via the HCT (heat code traceability) code. Being able to easily access HCT information related to specific instrumentation products can be of great assistance during purchasing and implementation, and throughout lifecycles as well.
However, many competitors in the small-bore fluid flow product market are unable to supply part-specific HCT information. This can particularly be the case after the sale has been made. If information is available, users might also be presented with a 'typical materials certificate' - which is not the same thing as an actual 3.1 certificate. In some cases such information might not even detail actual test results, but merely state that a manufacturer produces certain components within a recognised tolerance range for the type of material.
How to access Parker's 3.1 test certificates?
Parker has developed a database tool to meet the need for comprehensive, and part-specific, HCT materials traceability information - at any time in a product's life. A simple search allows users to get back to the specific test certificate, which Parker stores on behalf of the end user - eliminating the need for complex and expensive document management and access computer systems. The most common method of access is simply to phone the local Parker sales outlet, where someone will query the database and relay the information. However, customers can also be given direct access.
Different parts of a product may have different HCT codes.
How do end users use HCT information?
- check materials meet code requirements
- check composition to ensure correct welding
- verify materials during storage/handling or installation/MRO
- support investigations into damage/failure
