Product Description

As a safe alternative to asbestos, calcium silicate is commonly used for insulation materials that require high-temperature resistance. Calcium silicate is frequently used to fabricate insulation for industrial piping and equipment. Fabricating it is a regular aspect of the insulation apprenticeship curriculum. Calcium silicate rivals rockwool and other insulation materials like sodium silicate bonded vermiculite and perlite mixture in the same fields.

A secure replacement for asbestos in insulation materials at high temperatures is calcium silicate. Calcium silicate is a commonly used material for fabricating insulation in industrial-grade piping and equipment. Fabricating it is a regular part of the insulation apprenticeship curriculum. Calcium silicate competes with rockwool, sodium silicate-bonded vermiculite, and perlite mixture among proprietary insulation solids in these domains.

Producing Calcium Silicate Pipes – A Guide

Porous calcium silicate pipe, also called asbestos-free pipe calcium silicate, is produced by mixing, heating, gelling, molding, autoclaving, and drying processes to create a fiber-reinforced calcium silicate pipe. A new variation of rigid insulation material is the calcium silicate pipe.

  • The utilization of these backing insulation materials is clearly effective for conserving energy due to their ability to accumulate less heat and provide increased heat protection.
  • The boards maintain good durability even after prolonged use as they don’t shrink, deform or produce powder and their insulation performance remains constant.
  • Woodworking tools that are commonly used can be utilized to cut it into any desired shape with ease, and it can be combined with other materials by simply gluing and molding it.
  • The calcium silicate tube possesses the highest rate strength among thermo inorganic materials, enabling significant reduction in the overall weight of kilns and stoves during the design phase.
  • Environmental protection involves producing products that are free from corrosives and toxicity. These products should not emit exhaust gases or emit peculiar smells, especially under high temperatures. Additionally, they should not cause any harm or pollution to both the environment and human body. Such products can be classified as environmentally friendly.
