The outer diameter of the tube of the sound tube is indicated by the letter D, followed by the size and wall thickness of the outer diameter. For example, the seamless tube with an outer diameter of the sound tube of 105 has a wall thickness of 6mm, indicated by D107/5. The tube is also indicated by the outer diameter, such as De63. Others such as reinforced concrete pipes, cast iron pipes, and galvanized pipes are indicated by DN. In the design drawings, the nominal diameter is generally used to indicate that the nominal diameter is intended for design, manufacture, and maintenance. The scale defined is also the nominal diameter and is the specification of the tube (or fitting). A certain channel should be left between the file and the sound tube. The width of the check channel is generally about 0.5m. The width of the access channel depends on the material size and the transport machinery, generally 1.5 to 2m.

The stacking height of sound tube is not more than 1.2m for manual operation, 1.5m for mechanical operation, and not more than 2.5m in width

If the sound tube is piled up in the open air, it is necessary to prevent wooden mats or bars under the sound tube, and the surface should be slightly inclined to facilitate drainage, and pay attention to the straightness of the steel tube to prevent bending of the steel tube.

The sound tube is generally higher in strength than the straight seam sound tube. It can produce narrower tubes with larger diameters. It can also use the same width blank to produce sound tubes with different diameters. However, compared with the same length of straight seam pipe, the weld length is increased by 40 to 100, and the production speed is low. After cutting into a single sound tube, each of the three sounding tube heads must undergo a strict first inspection system to check the mechanical properties of the weld, the chemical composition, the fusion condition, the surface quality of the sound tube, and inspections through non-destructive testing. Ensure that the production of the sound measurement control tube can be officially put into production. The sound tube production process is simple, the production efficiency is high, the cost is low, and the development is rapid.

The height of the bottom of the bottom of the sound tube according to the detailed situation, if the warehouse is a rising cement floor, the height of the cushion can be 0.1m; if it is a mud, it must be 0.2 to 0.5m. If the sound tube is stored in the open air, the height of the cement floor should be about 0.3 to 0.5m, and the height of the sediment floor should be 0.5 to 0.7m.
