The conventional carcass made from a flexible metallic layer which has the potential of corrosion and weight issue as the main problems during installation operation. The {\^a}??ball-and-socket{\^a}?? concept is made from glass epoxy material and with an interlocking design that made from several segment to form a single pipe length. The use of composite has its benefit in term of strength, stiffness and weight as compared with conventional carcass pipe. The results showed that {\^a}??ball-and-socket{\^a}?? design has solved the second issue of having heavy weight while still maintaining adequate structural strength to hold the hydrostatic pressure. {\^A}{\copyright} 2016 Taylor \& Francis Group, London.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85009827057&doi=10.1201\%2fb21942-106&partnerID=40&md5=faa227ee825b6280d726a2e4b99b056e} }
