Disclosed are methods of manufacturing a pipe assembly (100). One method comprises: combining a fiber material and a binding polymer to form a composite material (130); providing a mandrel comprising an outer surface; covering a segment of the outer surface by winding the composite material (130) around the segment; providing a sleeve (110) comprising at least one interface (112A) for restricting axial movement of a device fastened to the sleeve, the sleeve further comprising at least one hole (111) for installing a pin (120) through the hole (111); placing the sleeve (110) around a portion of the wound composite material (130); for one or more of the at least one hole, installing a pin (120) through the hole (111) of the sleeve (110) and into the composite material (130) without reaching the outer surface of the mandrel, thereby forming an intermediate assembly; and heat curing the intermediate assembly. Also disclosed are pipe assemblies (100) obtainable by the methods, and pipes (300) including the pipe assemblies (100).
