hi,if the pipes keep blowing off the intercooler its probably because of oil residue on the insides of the hoses where they sit on the intercooler..make sure the hoses are cleaned with brake cleaner or similar as well as the pipes on the intercooler itself then secure tight with good quality hose clips..this should cure the problem.is it petrol or diesel,turbo could also be overboosting if the wastegate is sticking..hope this helps..
