PU Pneumatic hose suitable for air, general industrial water, non-corrosive oils. To maintain a long service life, will face used on the rated working pressure and ambient temperature. As the temperature rises, the working pressure should be reduced, if it exceeds the limit, the hose may be broken. Fluid temperature is too high or corrosive chemical fluid costs may lead to polyurethane air hose rupture, ambient temperature is too high or workspace chemical gases may cause the hose to crack, storage in damp places or deposit side of too long, it will make the hose hydrolysis or aging, may lead to breakage

Spiral hose characteristics

Spiral hose characteristics: Longitudinal production process is simple, high production efficiency, low cost, rapid development. The strength of the Pneumatic Tube welded pipe is generally higher than the Longitudinal, can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different pipe diameters. However, compared with the same length of straight pipe seam weld length of 30 to 100%, and lower production rate. Therefore, smaller diameter pipe were powered by straight seam welded, large diameter spiral welded pipe for the most part.

How to increase stability Spiral hose of

How to increase stability Spiral hose of:
First, small and medium steel, wire rod, rebar, medium diameter steel pipe, steel wire and wire rope, etc., can be expected in a well-ventilated storage shed, but it must be the underlying thatch.
Second, some small steel, sheet, strip, silicon, or thin-walled small-diameter steel pipes, all kinds of cold-rolled, cold-drawn steel products and high prices, corrosive metal products, can be stored for storage.

Spiral tube with solvents

Spiral tube with solvents, emulsions, cleaning steel exterior, to reach the removal of oil, grease, dust, smoothing agents, and similar organic matter, but it does not remove the steel appearance of rust, scale, welding flux, and thus in the production of corrosion only as adjuvant trick. The primary use of wire brushes and other tools of polished steel look, you can remove loose or warped scale, rust, welding slag. Hand tools rust can reach Sa2 level, power tools rust can reach Sa3 level, if attached to solid iron oxide steel outer skin, Pneumatic Tube the result is not ideal tools rust, corrosion of the anchor pattern depth of less than construction requirements.

Pneumatic industrial development

Although the country's pneumatic air hose has reached a certain scale and technical level, but compared with the international advanced level, the gap is very big. Our pneumatic product output accounted for only 1.3 percent of the world GDP, only the United States, 1/21, 1/15 Japan, Germany 1/8. This is a big country with a population of over 10 million is not commensurate. From the species point of view, a Japanese company has 6500 species, of which only one-fifth. The gap between product performance and quality levels are also high.
