Abstract

The invention discloses a welded pipe air tightness detection system and a detection process thereof, and belongs to the technical field of welded pipe detection. The welded pipe air tightness detection system comprises a feeding device, a detection water tank, a clamping assembly, a water tank turnover device, a water pressure supercharging device and a discharging table. The feeding device is arranged on the ground, and the water tank turnover device is installed at one side of the feeding device; the detection water tank is mounted at the top of the water tank turnover device, the clamping assembly is mounted in the detection water tank, the water pressure supercharging device is mounted at one side of the feeding device, and the discharging table is arranged at the side, away from the feeding device, of the detection water tank. According to the method, the two ends of a welded pipe are blocked, the welded pipe is placed in the detection water tank filled with water, the detection time is set to be five minutes, the water pressure in the detection water tank is increased, the welded pipe is taken out after five minutes, the water in the detection water tank is pumped out, and the water inflow amount entering the welded pipe is calculated by comparing the reduction amount of the water amount, so that whether the air tightness of the welded pipe is qualified or not is judged through the method.

Description

technical field [0001] The invention relates to the technical field of welded pipe detection, in particular to a welded pipe airtightness detection system and a detection process based on the system. Background technique [0002] Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip steel after crimping and welding, generally with a length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, there are many varieties and specifications, and the investment in equipment is small, but the general strength is lower than that of seamless steel pipe. The air tightness detection of welded pipes is particularly important. In the prior art, gas is usually used to detect the airtightness of welded pipes. Tiny gases are not easy to observe and count, resulting in inaccurate detection results and unintuitive detection process. Contents of the invention [0003] Embodiments of the present invention p...
