Pipes and elbows abrasion in pneumatic conveying systems is a considerable problem when products and granules containing elements of high hardness are being employed, elements such as :

  • Glass
  • Corundum
  • Small balls and metal powders
  • Foundry sands
  • Silica
  • Quartz
  • Titanium dioxide
  • Polypropylene reinforced with glass-fiber
  • Nylon reinforced with glass-fiber or carbon-fiber
  • Glass fiber.

Elbows and other parts of piping could require weekly interventions to weld sections or repair those parts perforated by abrasive action. This problem cannot be solved even if dense phase pneumatic conveying systems (low speed and high pressure) are used.

In order to meet this requirement, F.lli Sacchi has developed abrasion-resistant and wearing-resistant elbows and piping made of innovative composite materials characterised by high hardness (tables confirm that only diamonds are harder!).

Exhaustive studying of these materials and the innovative assembling, consisting in an external armour made of technical elastomer, has allowed us to obtain wearing-resistant elbows with astonishing performances:

  • Incredible wearing-resistant characteristics
  • Incredible abrasion-resistant performances
  • THE ONLY ELBOW OF 12KG WEIGHT (OTHER ELBOWS ARE MORE THAN 100 Kg!!)
  • Very high hardness of internal armour
  • External armour in technical high performance elastomer
  • Extremely low weight (starting from 10 Kg for a 90° elbow)
  • Easy to install, it’s possible to choose assembling with flanges or Morris type
  • Piping lifetime can increase from ”few weeks” to ”many years”

F.lli Sacchi can produce, upon customer’s request, wearing-resistant components such as:

  • Piping
  • Slide conveyors
  • Directional convertor
  • Stop devices
