characteristics of PU Spiral Tube‎

PU Spiral Tube‎ characteristics: Longitudinal production process is simple, high production efficiency, low cost, rapid development. The strength of the high temperature 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.

The Evaluation of PU Tube

In most cases without any testing tools and testing conditions we can according to the visual, olfactory, tactile sensory rough identification of PU Spiral Tube‎ quality.

1. Observe whether the lumen is regular or not. Good quality PU tube lumen and the outer edge of the standard circular? Ring wall evenly distributed. The diameter of 89mm? 7mm wall thickness of PU tube, for example? Poor quality of the thickest tube wall can reach 7.5mm? The thinnest at only 5.5mm? Working in the larger pressure? Easily lead to uneven wall high temperature pneumatic tube burst or deformation? Affect the normal use.

2. Observe the presence of bubbles or other visually visible objects in the PU tube wall, and see if they are colorless and transparent. High-quality PU tube wall crystal clear? Without any impurities. The defective PU tube color yellowing? May be in the production process due to improper handling decomposition, aging? Or improper storage due to long-term.

3, high-quality PU tube in addition to a little plastic odor outside? No other petrochemical products smell. The poor steel pipe has a pungent smell of diesel oil? Especially in the hot summer? People can not be close.

4, high-quality PU tube inside and outside the pipe wall are smooth? Feel good? And low-quality pipe is more rough.

5, when measuring the wall thickness should be cut off the ends of the PU tube? Select the middle tube as a sample test to prevent some illegal manufacturers make an article in the tube at both ends of the actual wall thickness at both ends of the tube.

6, at both ends of the PU tube interception of a few centimeters of the wire? Repeated folding wire? Detection of steel wire strength and toughness. Poor quality of the wire folded a couple of will break? And high-quality PU pipe steel wire to be special tools to cut off. The quality of steel wire determines the quality of the entire pipe? Due to quality problems caused by steel pipe PU tube is prone to irreversible deformation

The methods to store pneumatic tube

The PE pneumatic air hose products should be stored in a way that does not allow for excessive stress, elongation or deformation and should be avoided from contact with sharp objects or the ground. Whenever possible, use storage racks to store hose products. PU spiral tube‎ or hose assembly should be stored flat, it is best not to stack. If stacking is unavoidable, the height of the stack should be limited to the extent that no permanent deformation of the hose at the bottom is caused. Coiled hose products shall not be suspended from stakes. Hose and hose assemblies supplied in a straightened condition shall be stored flat and shall not bend. Large diameter hoses used in the petroleum industry should be fitted with caps on the ends.

PU Spiral Tube‎ is extruded from a soft, flexible elastomer

PU Spiral Tube‎ is extruded from a soft, flexible elastomer same as PU tubes. Tubing gives excellent abrasion resistance, kink resistance and tight bend radii, combined with good strength & flexibility. The high pressure pneumatic hose is ideal for arduous situations where vibration and flexing prevents the use of more traditional materials on Pneumatic automation industry, pneumatic robots.

Pneumatic Tools - PU Spiral Tube‎

Automated machinery, coating machinery, all kinds of pneumatic tools, pneumatic & hydraulic machinery, construction and various pneumatic tools. Polyether based PU Spiral Tube‎ is hydrolysis-resistant, anti-bacterial & anti-fungous, and it can be used for gardening, cleaning, water high pressure pneumatic hose and other purposes. Ether type is resistance to hydrolysis, fungus and weatherability. Ester type give maximum abrasion resistance and good oil, solvent and great resistance.

Polyurethane tubes with excellent hydrolysis, oil and cold resistance

Polyurethane tubes is ether-based to provide excellent hydrolysis, oil and cold resistance.This tubing is strong, flexible, and offers superior kink resistance compared to other pneumatic air hose tubing. It can be used in pneumatic tubing applications requiring a high pressure air hose. With its extremely tight outside diameter tolerance, PU Spiral Tube‎ is ideal for use with NITRA push-to-connect fittings.The UV stabilized dark green polyurethane tubing is excellent for outdoor use

Related brief description about PU tube hardness and quality is inversely proportional

In the normal trafficking process, customers always encounter numerous doubts the existence of PU tube hardness. Existing Flex PU tube are in accordance with the industry's effort to weigh the Shore scale. I plant commonly used raw material hardness is 85A ~ 95A. A unquestionable reality is, PU material hardness is inversely proportional with the price. In the production and trafficking is among the lasting process, not only to the production staff, to customers and to the formation of a PU material softer prices more expensive, softer quality PU tube more unilateral nature of good insight.

In fact, because of the diversity and complexity, PU using contemporary production have become more common, the use of the production is also increasingly diverse, softness PU Spiral Tube‎ is to be based on the details of production to determine, like tube body necessary embedded object, this time a little low hardness necessary PU tube. The need to clarify that the hardness PU tube Polyurethane air Hose with its own interests and not the quality of indirect contact, but necessary in order to adapt production and life.

Here is necessary particularly point out, the industry PU tube production in winter and summer softness is changed. Winter hardness appropriate point was low because of thermal expansion and contraction of plastic, hard winter tube, PU tube production is low hardness, is more convenient for the customer in the use of, for example, to close the tube key. Summer PU tube hardness will increase a little, higher summer temperatures outside, PU tube expansion, high hardness that is resistant to 10 kg for the low-pressure tube without presenting the case and even bubble burst pipe.
