ABSTRACT:
A fiber reinforced plastic pipe tee is formed by winding glass rovings around a mandrel in a plurality of wrap patterns which collectively cover the pipe tee. A tape having synthetic fiber warp and glass roving weft is included in wrapping of the pipe tee. Such glass reinforcing fibers are oriented in the tee for resisting biaxial stresses. A bulge is provided on each side of the pipe tee in the diaphragm area for resisting biaxial stresses without introducing problems in winding the pipe tee.
