Abstract

The invention provides a pressure test method for pipe fittings, which is especially suitable for pipes without pipe joints. The pressure test device used includes a T-slot butt welded pipe pressure test platform and a pipe clamping device. During work, the movable gear is placed on the pressure test pipe fittings. On the left and right sides, the adjusting rod passes through the long strip hole on the fixed plate and is threadedly connected with the slider; at the end of the pressure test pipe, install gaskets, pressure test blind plates and I-shaped steel in sequence, so that the end of the adjusting rod is in line with the I-shaped Steel contact, the present invention solves the problems of cumbersome operating procedures, waste of materials and man-hours, low efficiency, poor safety, etc. The operating procedures are simple, and the existing conditions of this platform only need to be matched with the blind plate method suitable for the pipeline The pressure test can be completed by using the flange and the gasket, which solves the problems of waste of materials, labor hours and low efficiency. The safety factor is high. This platform replaces the connection of the Norma pipeline connector, and the fixing effect is more reliable. It can be used flexibly on the pressure test platform.

Description

technical field [0001] The invention relates to the field of pipeline construction, in particular to a pressure test method using a pipe fitting. Background technique [0002] The oil drilling platform tends to be a kind of special marine manufacturing equipment. The hydraulic stainless steel pipes used have high requirements, and most of the pipelines are connected by butt welding. Therefore, a key process in pipeline construction is used as a test for the quality of pipeline welding and pipe materials. One of the main methods is to verify the welding quality and pipeline material quality, whether the pressure range meets the design requirements and whether there are other unsafe factors found. It is a key process before the pipeline is put into operation. [0003] According to the rules of the classification society, after the butt welded pipe is prefabricated in the workshop, like the flanged pipe, a pressure test of 1.5 times the design pressure is required to check the ...
