Curious about the topic of on-site machining, Valve World contacted Velan's jerome Niogret for some inside information. Ask any engineer and he or she will probably confirm that the easiest place to conduct valve repairs has to be inside a well-appointed machine shop. After all, this is where staff will have ready access to the tools, machinery and spare parts they are likely to need. However, from time to time it may be necessary to carry out repairs on-site, explains Velan's Mr. Jerome Niogret. "Take welded valves for example. Removing them from the installation, transporting them back to our premises for repairs and reinstalling afterwards would be a time-consuming undertaking. In the oil and gas business sector repair in the field is pretty much mandatory to save time and costs and avoid having to send valves back to our factory. Obviously if the repair cannot be done by portable machining devices then a transport to our factory or replacement is necessary. Regulations can also be another reason to work on valves in-situ. Valves can for example be installed inside nuclear power plants and therefore be considered as nuclear equipment which should not be removed."
