BS 7335-2 is a British Standard. BS 7335-2 is the 2nd part of the BS 7335 series on the installation of monolithic refractories.
BS 7335-2 specifies scope, definitions, planning, personnel, gunning materials, and a wide range of necessary details. BS 7335-2 describes good practices for working procedures in the installation of refractory linings by gunning techniques. The code is specifically concerned with the “dry” gunning of initial or replacement linings, using refractory materials bonded by calcium aluminate cement.
Major repairs, involving the removal of old panels of the lining back to the shell, are also covered. Wet gunning and gunning repairs to hot linings are excluded. The gunning of linings for steel chimneys is specifically described in BS 4207.
Note 1: The installation should be planned in detail, in advance, so that work on site can proceed quickly and efficiently.
Note 2: The titles of the publications referred to in BS 7335-2 are listed on the inside back cover.
Note 3: Wet gunning and gunning repairs to hot linings are excluded.
BS 7335-2 on monolithic refractories installation and regulation is useful for:
Because of their high temperature shock tolerance, chemical inertia, and other properties, monolithic refractories have a broad range of industrial applications.
BS 7335-2 best practice guidelines provide a code of practice for the installation of refractory linings using gunning, specifically concerned with the “dry” gunning of initial or replacement linings, using refractory materials bonded by calcium aluminate cement.
BS 7335-2 guidelines help to speed up installation, improve reliability, and assure best-in-class practices.
