Inquiry (采购产品): pipe couplings Could you please help me with information relating to the design of mechanical pipe couplings(probably steel). I am final year civil engineering student at the University of Botswana doing a research project in jointing problems in pipes.If possible could you send me material on causes of leakages, factors to consider in design of couplings and samples of available mechanical couplings together with the design procedure. **** Hidden Message ***** Thomas Alfred Melato GaboroneN/A BWA Company: Student Phone: +26771793395 E-mail: melatotom@yahoo.com **** Hidden Message ***** melatotom@yahoo.com
