AP slabs are available from 1500 to 3000 mm long.

AP slabs are available from 1500 to 3000 mm long. When testing for bending evenly distributed load, they withstand a load of at least 1000 kg.

To protect against mechanical damage to the thermal insulation applied to pipelines, the asbestos -cement industry produces special semi -cylinders. Their length is 1200 mm, thickness — 5.5 mm. The limit of the strength of the bend of asbestos cement from which the semi -cylinders are formed — at least 140 kg/cm2, water absorption — no more than 30%.
