What Is The Raw Material Of The Sonic Tube
- Aug 07, 2018 -

The sounding tube is composed of a bottom pipe, a middle pipe, a bottom plug and a sealing rubber ring.

The main material of the sounding tube is the thin wall welded pipe, and the material is generally Q195 - Q235 -Q235B.

The specifications of commonly used thin-walled welded pipes for acoustic tubes are mainly the following

Special thin-walled welded pipe for acoustic tube

50 thin-walled welded pipe specifications: 50*0.9, 50*1.0, 50*1.1, 50*1.2, 50*1.3, 50*1.4, 50*1.5, 50*1.8, 50*2.0, 50*2.2, 50*2.5, 50*2.75, 50*3.0, 50*3.5

54 thin-walled welded pipe specifications: 54*1.0, 54*1.1, 54*1.2, 54*1.3, 54*1.4, 54*1.5, 54*1.8, 54*2.0, 54*2.2, 54*2.5, 54*2.75, 54*3.0, 54*3.5

57 thin-walled welded pipe specifications: 57*1.0, 57*1.1, 57*1.2, 57*1.3, 57*1.4, 57*1.5, 57*1.8, 57*2.0, 57*2.5, 57*2.75, 57*3.0, 57*3.5

The selection of acoustic tube material is based on the principle of large sound penetration rate, easy installation and low cost. By processing 12 meters thin wall welded pipe into 3 meters, 6 meters, 9 meters and so on, then welded joint on both ends, so a sound tube is completed.
