[0002] During the construction of ship piping systems, a large number of test pipes and sampling pipes need to be tested on site, and temporary gaskets need to be installed on the test pipes during the test. During the on-site test, two 3MM welding rods are usually used to remove the coating or aramid rubber gaskets as temporary gaskets, and then four bolts are installed for test. Both methods cause waste of welding rods or aramid rubber gaskets, and there is a phenomenon that the pipe fittings exceed the flange surface during the on-site test, and the flange bottom welding position is not reserved, resulting in the need to bore the removed test pipes first. Each pipe must be manually lifted to the boring machine for fixing, and two people cooperate with one person to operate the boring machine. A large number of pipes are often piled up on site waiting for boring, causing production waiting and wasting manpower and material resources. Summary of the invention

During the test installation of the pipe fitting 2, the flat bar 1 is placed at the end of the pipe fitting 2 as a gasket. At this time, the bottom seal positioning assembly is used to position the flange 3 of the pipe fitting 2 by abutting against the end of the pipe fitting 2, effectively providing a welding position for the flange 3 bottom seal. The present application integrates the gasket and the flange 3 bottom seal positioning into one, with multiple functions, and jointly meets the test installation requirements of the pipe fitting 2, making the test installation of the pipe fitting 2 more convenient and quick. The use of the flat bar 1 as a gasket and the method of using two 3MM welding rods to remove the coating or aramid rubber gasket as a temporary gasket, and then installing four bolts for test installation, both reduce the waste of materials.

The four threaded blocks 4 are symmetrically distributed, and the cross-section of the threaded blocks 4 is T-shaped. When in use, the two flat bars 1 are placed at the ends of the pipe fittings 2 as gaskets, and the threaded blocks 4 are connected to the ends of the pipe fittings 2 according to the size requirements of the pipe fittings 2.
