Pilot Plant vessels are typically full length but small diameter to allow the OEM to replicate full scale performance conditions in a more economical scal. All-Weld has worked with many international Engineering and Design companies designing and supplying pilot plant scale pressure vessels, heat exchangers and other process equipment. Pilot plant vessels may contain internals such as packed beds, trays, spray headers or liquid cllection media. Material of construction may be from steel, stainless steel, Chrome alloys or Nickel alloys. Vessels can be supplied stand-alone or installed in Modular skids with assembly of piping and associated components.
