Tai Yu Feng Steel Tube Co.   

Acoustic pipe is made of high quality stone machined and hand-made fine grinding. Optional stone "Ji'nan green" "green Taishan" "Taishan greenish white grain", these stones have high strength, high hardness, precise structure, uniform texture, good stability, can maintain relatively high accuracy in the heavy load and the general temperature changes, and has no rust, wear resistance, the same type, acid and alkali resistance, not magnetic, easy cleaning, convenient maintenance etc.. Is a high precision measuring tool precision machinery factory. The corresponding acoustic pipe measuring and: acoustic pipe square box, acoustic pipe foot harmonic measuring tube square cylinder etc.. Acoustic pipe sounding pipe also called acoustic pipe are paired, can replace the high block, is mainly used for measuring the parallelism of the workpiece, acoustic pipe straightness and parallelism requires compliance with JB/T7975-1999. Acoustic pipe is high precision reference measurement tools, test of the instrument, precision tools, machinery parts, is the ideal reference surface. Measurement of acoustic measuring tube for industrial production and laboratory, especially for the measurement of high precision, the granite is non-metallic materials, no magnetic response, no plastic deformation of acoustic pipe physical stability, coordinated by the impact of grain boundary surface shedding, lint free, does not affect the plane precision. In the use of rock plate measuring even by heavy bump, at least out of stone ballast only, and not as metal tools that, due to deformation and damage of precision. Precision measurement reference part of its superior quality cast iron and steel production, can obtain the precision high and stable measuring tube is very brittle, afraid of hard object impact, beating, so usually in the measurement of the workpiece or notice in gently, avoid striking the platform surface iron weights, to avoid excessive pits, effect of its use also affect its appearance. Long term under the condition of no use should be based on the special lubricating oil wipe the acoustic pipe, if no special lubricating oil can replace edible oil, with a soft cloth to wipe the use of the time once again dry, when the surface contamination should take some corrosion lighter agents such as lemon juice or vinegar to clean the dirty, do not use soap or soda powder etc. the vulnerability of acoustic pipe material to wipe essence. Acoustic pipe [1] which belongs to a tool for high precision measurement, its production and processing to the inspection of the factory the whole process is completed in a constant temperature room, after the factory because of the external temperature and humidity changes greatly in the process of transportation, loading and unloading strength is too large and transit bumps will cause a certain impact on the accuracy of acoustic pipe. Of course, as a result of acoustic pipe adopts the foam board isolation treatment and the use of all wood packaging, can greatly reduce the impact loading and transportation process on its accuracy, ensure the acoustic pipe transportation safety. But in order to ensure the product to another environment can have a relatively good performance, recommend acoustic pipe transportation to a new environment will be placed in a constant temperature room the first 2-3 days before use.
