    Abstract：Wall thickness of pipe fittings in domestic gas pipelines， especially tees and elbows， are becoming more and more thickened in high pressure and large diameter design conditions if mathematical analysis is adopted to calculate， which results in being difficult to assure quality of pipe fittings. In order to solve the problem， verification test method shall be adopted according to relative provisions in pipe fitting standards. Introduced is the method， which is not only able to solve the above mentioned technical problem， but also suitable for calculation of various design parameters of pipe fittings. Through usage of this method， pipe fitting wall thickness can be reduced and manufacture difficulty and costs can be decreased greatly. It is demonstrated that the verification test method is not cause of a simple burst strength test. Described are main works of the method and put forward are relative suggestions.
