The stress state of elliptical bottoms with centrally located branch pipes reinforced with a monolithic insert or cover ring is analyzed and experimentally investigated. Five zones of maximum stresses are exposed and examined in the designs employed for reinforcement of couplings. The advantage of the cover-ring design is established.
