WELDED
SILO

Features

They allow the storage of fine bulk materials, such as powders, flours, among others.

100% manufactured in our plant or welded in the field, we deliver them ready for use, with ISO9000:2015 certified quality system.

Designed to withstand mass flow patterns, with central, lateral or tangential loading and central or eccentric discharge.

Manual and semi-automatic processes for welding application.

Internal and/or external coating according to the application. Factory applied and oven dried.

Wide range of sizes, from 2.3 m diameter.

Cone discharge angle from 0° to 75°.

Can be installed above finished floor level, inside existing buildings, platforms or elevated structures.

Coatings

Surface preparation or abrasive shot blasting, under the specification of the SSPC Standard in its different types: SSPC-SP 6/NACE N°3 Commercial Shot Blasting, SSPC-SP 10/NACE N°2 Semi-White Shot Blasting, SSPC-SP 5/NACE N° 1 White Metal Shot Blasting.

Application of High Solids Epoxy Primer.

Final finish with High Solids Polyurethane Enamel, the method of paint application is by spraying.

Interior coatings are designed to work in high and low abrasion conditions, all components are FDA certified.

The exterior coatings are designed to work under moderate and high abrasion environmental conditions.

Finishes

Finishes are directly related to the material being stored, these can be weld cleaning only, weld bead stripping or as specialized for the food or pharmaceutical industry with a roughness finish of Ra= 1.6µm to 0.8 µm.

As part of the quality assurance of welded joints, they are inspected by ASNT certified personnel in the following non-destructive tests:

Visual Inspection Level II (VT)

Liquid Penetrant Level II (PT)

Industrial Ultrasonic Level II (UT)

Level II X-Ray Testing (RT)
