Based on the blog post “Chemical Injection Quill for Oil & Gas” written by my colleague Kevin Alamag, I would like to dive more into the depth of the application fields of Injection \/ Sampling DBB Valves.\u00a0<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

In my course of work talking to OEMs, EPCs, end-users and other clients on this injection\/sampling area, I was surprised to know that there are many misunderstandings on this small but important product range within the whole process.<\/p>

Within our AS-Schneider product range, an injection or sampling probe comes in combination with a double block and bleed valve as a one complete product. As the name suggest, injection is used when adding additives into the media in the pipeline, to produce a product according to end user specification. As for sampling, purpose is to draw media out from a pipeline, and this media will be use as sample, that will be sent to a lab, to check if the sample drawn from this sector is within the product parameters.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Having an inserted item into a pipeline can proved to be disastrous if its not designed correctly. Take for instance, in 1995, a serious incident happened when a thermowell broke off in the pipeline at Monju Nuclear Powerplant in Japan. It came perilously close to causing an explosion that could have caused a radiation leak.<\/p>

Manufacturers need to take a serious view when performing the Wake Frequency Calculation, to check if the probe length require is suitable according to the flow parameters given by the end user.<\/p>

According to process engineers, general rule of thumb on how much length to be immersed in the pipeline is as follows: \u00a0<\/p>
