Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel seamless pipes, in particular to a high-sensitivity stainless steel seamless pipe leakage alarm device. Background Art

[0002] Seamless steel pipe is made by perforating a whole round steel. There is no weld on the surface of the steel pipe, which is called seamless steel pipe. According to the production method, seamless steel pipe can be divided into hot-rolled seamless steel pipe, cold-rolled seamless steel pipe, cold-drawn seamless steel pipe, extruded seamless steel pipe, jacking pipe, etc. Seamless steel pipe is mainly used as petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high-precision structural steel pipe for automobile, tractor and aviation.

[0003] When two seamless steel pipes are installed and connected, welding is generally used for connection. However, mistakes are prone to occur during welding, which may lead to leakage problems at the welding points of the seamless steel pipes during use. Especially for seamless steel pipes exposed to the outside, it is difficult to detect them in time through manual inspection under the influence of external factors, which will cause unnecessary harm.

[0007] Preferably, a rubber layer is provided at the joints between the two sealing rings and the tube body.

[0008] Preferably, two tube bodies are provided, and the two sealing rings are located at the connection between the two tube bodies.

[0009] Preferably, the pressure relief grooves are all in a circular shape, and the connecting grooves are all in a square shape.

[0010] Compared with the prior art, the beneficial effects of the utility model are: a sealing ring, a support rod, a striking plate and an alarm bell, etc. are provided. When a leakage problem occurs at the welding point of the seamless steel pipe, the leaked gas will rush into the interior of the sealing ring, and at the same time the air pressure will impact the striking plate. The impacted striking plate will continuously hit the alarm bell, causing the alarm bell to continuously sound, thereby serving as an alarm, reminding the staff that there is a leakage problem in the seamless steel pipe, so that the staff can discover and solve the problem in time, thereby improving the service life of the seamless steel pipe.
