background about the mechanical spare parts that use in shipping oil called (packing )which is in the loading arms Although I have done the experiments on one part called (packing) in the loading arm , i found out some results but I could not make up a case study for this practical work and could not find a good title for it . I have all the pictures of the experiments and the part , I need to have abstract between 150-200 words , introduction , the experiments , discussion , results, conclusion , acknowledgment ,references I have all the information neede for this scientific paper (case study ) . This information is in Word . This is the spare part that I have done some experiments on it , this part called packing which is in the loading arm of shipping oil. This tool usually caused of big problems which is leaking problem I have done some experiments on this tool (Packing ) which contains two parts steel and plastic . The experiments that i have done are : 1- The CSM Tribometers 2- Differential Scanning Calorimetry (DSC) 3- Tensile testing machine mechanical Do you have a good background on these experiments and how we test the spare part that I have mentioned before ?
