Problems solved by technology

[0004] The above technical solution uses the fluid pressure difference on both sides of the cleaning pig as the driving force of the cleaning pig, but the flowing medium in this driving mode will take away the impurities cleaned by the cleaning pig and pollute the conveying medium

Embodiment Construction

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0046] refer to figure 1 , is a pig blowing pipe 1 disclosed by the present invention, comprising a pig blowing pipe 1, a cleaning pig 2 slidably arranged in the blowing main pipe, and a pig blowing valve 3 arranged at both ends of the pig blowing pipe 1; The pig tube is fixed and welded coaxially by multiple equal-diameter steel pipes. Before welding, chamfer the nozzle of the steel pipe and clean the burrs, curling and splashes in the pipe, and then use compressed air to purge the inside of the steel pipe and clean it. Grease, paint and rust within 50mm of the end face of the gate, and then butt weld the adjacent pipes.

[0047] refer to figure 1 The blowing pig valve 3 includes a connecting section 31 and an installation section 32, the installation section 32 is provided with a quick-fit flange 321 at one end away from the connection section 31, the dia...

Abstract

The invention relates to a pigging pipe and a detection method thereof. The pigging pipe includes a pig-blowing pipe, a cleaning pig and pig-blowing valves arranged at both ends of the pig-blowing pipe. The cleaning pig includes a connecting rod I and a connecting rod II. A pre-cleaning device is arranged on the peripheral wall of the end, away from the connecting rod II, of the connecting rod I.A middle section scraping plate is detachably arranged between the connecting rod I and the connecting rod II. A driving device is arranged at the end, away from the connecting rod I, of the connecting rod II. The pigging pipe and the detection method thereof have the effect of using compressed air to drive the cleaning pig so as to collect impurities cleaned by the cleaning pig without pollutingtransportation media.

Description

technical field [0001] The invention relates to the technical field of pipeline cleaning, in particular to a pipeline for beating pigs and a detection method thereof. Background technique [0002] With the continuous development of the machinery industry, the requirements for the quality of lubricating oil are getting higher and higher. In order to produce high-quality lubricating oil with various brands, the ideal way for lubricating oil factories is to make each raw material and product have its own characteristics. Pipelines are used to avoid mutual contamination of media, but this will lead to high costs, and the actual pipeline layout is very difficult, and the factory area is also quite crowded. Therefore, pig pipes are usually used in actual production to achieve multiple uses without using Materials contaminate each other. [0003] The Chinese patent application publication number CN108361471A discloses a speed-adjustable submarine oil pipeline cleaning pig, which i...
