Yancheng Acoustic Pipe (187-3376-9273) - Yancheng Acoustic Pipe Quote - Yancheng Acoustic Pipe Test - Acoustic Pipe factory in Yancheng - Yancheng Acoustic Pipe prices - Yancheng Acoustic Pipe role - Yancheng acoustic tube quality - Yancheng sound Pipe Technology - Yancheng Acoustic Pipe Construction - Acoustic Pipe weight Yancheng - Yancheng Acoustic Pipe Specifications - Acoustic Pipe Yancheng Yancheng use acoustic tube into the pipe unit, multi-channel roll rolling, Yancheng acoustic tube gradually rolled , formed with an opening gap of a circular tube, adjusted reduction squeeze rollers so Yancheng acoustic tube gap control in 1 ~ 3mm, and weld ends flush. The gap is too large, reducing the proximity effect is caused by lack of eddy heat, Yancheng acoustic tube indirect co-crystal to produce fusion or cracking are not bad. The gap is caused by the proximity effect is too small increases, Yancheng acoustic tube heat excessive, resulting in Yancheng acoustic tube burning; or Yancheng acoustic tube extruded to form a pit after rolling, affect Yancheng acoustic tube surface quality . Yancheng Acoustic Pipe edge reach Yancheng acoustic tube temperature, the metal structure remains solid, forming incomplete fusion or penetration; insufficient when the heat input, Yancheng acoustic tube is heated over the edge of Yancheng acoustic tube temperature, produced a burning or droplets that form Yancheng acoustic tube Cave. Yancheng acoustic tube temperature, in the squeeze rollers squeeze, a common metal grains mutual penetration, crystallization, eventually forming a solid Yancheng acoustic tube. If the pressing force is too small, the number of co-crystals form small, Yancheng acoustic tube metal strength decline, the force generated after cracking; squeeze if the pressure is too big, it will cause molten metal is extruded Yancheng Acoustic pipe, not only reduces the Yancheng Acoustic Pipe strength, and will generate a lot of inside and outside, and even cause Yancheng acoustic tube ride joints and other defects.
