Embodiment 1

[0016] Embodiment 1: The composition of the corrosion-resistant steel is: C: 0.05%, Si: 0.05%, Mn: 0.1%, P: 0.02%, S: 0.01%, Al: 0.005%, N: 0.005%, Cr; 0.5%, Cu: 0.01%, Mo: 0.01%, Ni: 0.005%, and the rest is Fe, the unit is percent by mass.

Embodiment 2

[0017] Embodiment 2: The composition of the corrosion-resistant steel is: C: 0.1%, Si: 1%, Mn: 1%, P: 0.01%, S: 0.009%, Al: 0.05%, N: 0.004%, Cr: 0.4%, Cu: 0.1%, Mo: 0.1%, Ni: 0.05%, and the rest is Fe, the unit is percent by mass.

[0018] Embodiment 1: The composition of the corrosion-resistant steel is: C: 0.06%, Si: 0.06%, Mn: 0.6%, P: 0.009%, S: 0.009%, Al: 0.006%, N: 0.003%, Cr: 0.3%, Cu: 0.06%, Mo: 0.05%, Ni: 0.006%, and the rest is Fe, the unit is percent by mass.

[0019] The corrosion-resistant steel of the present invention can improve the corrosion resistance of the sampling tank, wherein C is an effective element for improving the strength of the steel material; Si can also improve the strength of the steel as a deoxidizer; Cr, Mo and Ni can greatly improve the corrosion resistance sex.

Abstract

The invention relates to a sampling device which comprises a sampling groove. The sampling groove is fixed at the lower end of a hanging plate, and the upper end of the hanging plate is foxed with a fixing plate. Sampling connection tubes are respectively installed on the left side and the right side above the sampling groove and fixed on the fixing plate through sampling tube clamps. The sampling device is characterized in that the sampling groove is made of a corrosion resisting steel product, wherein the corrosion resisting steel product comprises, by mass, C 0.05-0.1%, Si 0.05-0.1%, Mn 0.1-1%, P less than or equal to 0.02%, S less than or equal to 0.01%, Al 0.005-0.05%, N less than or equal to 0.005%, Cr less than or equal to 0.5%, Cu 0.01-0.1%, Mo 0.01-0.1%, Ni 0.005-0.05% and the balance of Fe. The sampling device displays a pressure value of a corresponding water layer through a pressure meter, accordingly can calculate the depth of the corresponding water layer, enables a worker to be capable of accurately sampling a required water layer and is accurate in sampling.

Description

technical field [0001] The invention relates to a sampling device, in particular to a sampling device used on a tank body. Background technique [0002] Sampling devices are required in large tanks (such as filter tanks and storage tanks), and the sampling devices are used to sample liquids (water or slurry, etc.). The sampling device in the prior art cannot accurately sample the liquid in each water layer, but can only roughly sample at the phase position. In addition, in the prior art, the sampling tank of the sampling device is generally made of ordinary carbon steel plate, and the service life will be reduced due to corrosion during use. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a sampling device that can accurately sample the liquid in each water layer, and the sampling tank of the sampling device has excellent corrosion resistance. [0004] According to the technical scheme p...
