Abstract

The invention provides a welding joint for fixing a fire-fighting corrugated pipe, and belongs to the technical field of fire-fighting facilities. The welding joint solves the problem that the fire-fighting pipe joint in the prior art is not durable. The welding joint for fixing a fire-fighting corrugated pipe includes a first pipe and a second pipe. The first pipe includes a first main body, a first pipe opening and a second pipe opening. The axes of the first pipe opening and the second pipe opening are perpendicular with each other. The second pipe includes a second main body, a third pipeopening and a fourth pipe opening. The axes of the third pipe opening and the fourth pipe opening are perpendicular with each other. The second pipe opening and the third pipe opening are fixed in weld mode. The welding joint has the advantage of being durable.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting appliances, and relates to a welding joint for fixing a fire-fighting corrugated pipe. Background technique [0002] Public places, small and medium-sized enterprises and residential areas all need to install fire protection facilities. Fire-fighting facilities include fire-fighting pipelines, which play an important role in fire-fighting operations. During the fire-fighting operation, the fire-fighting pipeline ensures the pressure and height of the water outlet. Due to the high pressure in the firefighting pipes, the joints of the existing firefighting pipes are often not durable and leak, which is caused by the defects of the various current firefighting pipe joints. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the existing technology, and propose a welded joint for fixing fire-fighting bellows. The present inventi...
