Pipe sections and methods for forming pipe sections are disclosed. A pipe section includes a hollow body, the hollow body having an inner surface and an outer surface, the inner surface defining an interior. The pipe section further includes a barrier layer surrounding the hollow body, the barrier layer having an inner surface and an outer surface. The barrier layer is formed from a polyarylene sulfide composition. The polyarylene sulfide composition includes a polyarylene sulfide and a crosslinked impact modifier. Such pipe sections exhibit high strength characteristics and flexibility as well as resistance to degradation, even in extreme temperature environments, while maintaining desirable processing characteristics.
