ACID RESISTANT BRICK ACCORDING TO DSTU Б В.2.7-255:2011

KP

Acid-resistant brick of VKP grade is used under heavy operating conditions, as it has such properties as durability and environment conditions resistance. Therefore, the acid-resistant ware are used in metallurgical, chemical, oil and gas, dairy industry, as well as at filling stations at paving, towers and tanks foundation laying, in chimneys, claddings of buildings, etc.

The main advantage of the acid-resistant ware is considered to be resistance to impact of aggressive chemical substances, high hardness, freeze resistance, low moisture adsorption, as well as their external specifications – accuracy of dimensions, smooth surface, etc.

Acid-resistant bricks of this refractory grade are divided into classes: A, B and C.
The products are delivered on wooden pallets laid with cardboard, protected with angles, wrapped with stretch-film and bundled with polypropylene or polyester strip.
