Test installation for transporting silica sand.

The Challenge

Covia Corp, a leading company in the manufacture and sale of industrial minerals in Mexico, required to pneumatic transport silica sand at 6 bar (with 50% solids). Initially they worked with 225mm (8”) HDPE pipes that suffered from high levels of wear at the elbows due to abrasion of the material it was carrying.

Pexgol Solution

The client decided to replace one of the HDPE elbows with a Pexgol 90° 225 mm (8”) class 15 and test it for 3 months.
HDPE elbows generally lasted up to a month and a half of work. The Pexgol elbow had to at least double the operating time to pass the test.
After 3 months of testing it was shown that Pexgol exceeded expectations. It’s been more than a year and the elbows continue to function without problems.
Only torque wrenches were used for the installation.
