Feature
● Each Pipe&Tube is traceable to its producing mill and heat by an identification number marked Labeling
● Each Pipe&Tube's bag is affixed with a label identifying the component's part number, date and LITECH lot number.
● All Pipe&Tubes are purged with UHP Nitrogen gas, capped, single-bagged for BA and double-bagged for EP and packaged for shipment in a ISO6 and ISO5 cleanroom.
