Be used for pressing pipeline microbial film collection system in area

Technical Field

The utility model belongs to microbial film collection system field, concretely relates to be used for pressing pipeline microbial film collection system in area.

Background

The microbial corrosion refers to the process that the life activity of the microbes and metabolites thereof directly or indirectly accelerate the corrosion of metal materials. Microorganisms are widely present in natural environments such as soil, seawater, etc., and microbial corrosion often occurs in buried pipelines, harbors, dams, power plants, sewage treatment systems, and oil fields, and is particularly serious in oil fields. The microbial corrosion causes great harm to the transportation and production of petroleum and natural gas, is one of important reasons for influencing the service life of underground pipelines, and causes great economic loss to the society. Microorganisms in the oil and gas pipeline exist in two states of being fixed on the pipe wall and being free in a water phase, the oil and gas field industry generally collects water samples to analyze the abundance of free bacteria to judge the microbial corrosion tendency and the sterilization measure effect, and sessile bacteria participate in the microbial corrosion process, so that the abundance data of the sessile bacteria on the pipe wall has more value for monitoring the microbial corrosion.

The tube wall sessile bacteria sample can be obtained through a bypass, an erosion coupon and a tube cleaning product. Other corrosion monitoring probes and hanging pieces are arranged on the bypass, so that the corrosion monitoring probes and hanging pieces are usually arranged behind the ball collecting barrel, the corrosion products on the surface of the ball collecting barrel cannot be cleaned in the pipe cleaning operation, and the collected sample cannot represent the real data of sessile bacteria in the long-distance pipeline. The wall shear stress borne by the corrosion hanging piece in the pipeline is higher than that of the pipeline wall, so that the corrosion hanging piece is not beneficial to microorganism adhesion, the collected sample sessile bacteria data is lower, and the existing acquisition of sessile bacteria sample source still has limitation.
