What cause high pressure hose crack and how to deal with it
The peristaltic pump hose has one or more high strength synthetic fiber braided layers. While the inner and outer layers of the hose are extruded. In general, the inner lining is synthetic rubber. The tube body is soft, elastic and has good wear resistance. While fibers inside the pipe body can enhance the overall performance. During use, it generates low heat and has good recovery property.
Such rubber hose can bear both positive and negative pressure. At the same time, it can resist acid, alkali, oil, high temp, etc. Thus it can transport more than 90% of the chemicals. As for the raw materials, it can be natural rubber, butyl rubber and EPDM rubber. Natural rubber can resist general weak acid. Besides, it has good wear resistance. While the butyl rubber can resist grease, alkali metal and solvents. Then the EPDM rubber resists ozone, weather and heat.
The operating temp of the peristaltic hose is max 100℃. But there will be heat in the producing process. Thus Orientflex recommend the medium temp should be less than 80℃. However, in some cases, there is good ventilation. On such occasion, the medium temp can reach 100℃.
Peristaltic pump hose application scope
Deliver acids, alkali, slurry and inorganic salt slurry such as titanium dioxide.
Transport various medical materials and liquids.
Deliver edible oil, beverage, beer, juice, etc in food industry.
Mining, metallurgy and raw material industries. Such as calcium carbonate, rolled steel, iron oxide scale and various ore slurry.
Paper industry, such as pulp and others.
Water treatment industry, such as sludge, lime slurry, etc.
Construction and building materials industry. Such as concrete, cement mortar, ceramic glaze slurry, etc.
Drilling mud in the petroleum industry;
Besides, peristaltic pump hose is ideal for nuclear waste and electrolytic waste residue. It’s’ also suitable for metal slag liquid, coatings, glue, latex, etc. While these materials have high viscosity and high particle content.
