GOODTEMP perlite fittings, maufactured by the Howred Corporation, are high temperature thermal pipe fittings made of expanded perlite and sodium silicate reinforced with fibers to increase impact resistance. This thermal insulation is corrosion-inhibited, moisture-resistant, fire-resistant, asbestos-free high temperature insulation.

GOODTEMP protects austenitic stainless steel piping and equipment from failure due to chloride stress corrosion cracking. GOODTEMP also inhibits corrosion of other ferrous metals. The unique characteristic of bonding millions of vitrified air cells gives abundant industrial applications to this inhibited high temperature insulation.
