Magnetic Drain Cover

Unbeatable experience in refining and petrochemical industries: Sulphur, present in all fuels, converts to sulphur oxides on combustion and on contact with water vapour to acid at lower dew point temperatures. Such acids and their combined chemicals (polythionic acid) migrate through the refractory linings to attack anchor weld points and steel casings, requiring large-scale, expensive repairs to process plant.

Hydrotemp has been successfully used for over 30 years to protect steel casings and anchor supports in all types of heaters, ducting and chimneys.

Hydrotemp has excellent adhesion to metal surfaces. Coverage: in severe aqueous or atmospheric conditions 0.6m² per litre to yield a thickness of 1.5mm.

A permanently flexible, non-oxidising anti-corrosive coating applicable from -26°C to 204°C.

Hydrotemp does not dry out or harden after application, which allows the product to expand/contract with the steel structure.

Hydrotemp contains no solvents and will neither soften nor liquify over its wide operating temperature range.

No special expensive preparation of steelwork is required, such as grit blasting. Cleaning off with a wire brush is required, to remove loose material.

Recommended coverage 0.6m²/l to yield 1.5mm

Corrosion under installation

External insulation & aluminium cladding applied to process piping and vessels is exposed to penetration by rain water containing atmospheric chlorides. Risk increases at pipe junctions and bends in piping systems.

Corrosion protection is required to repel water and protect the pipe or vessel from chloride attack.

It is also important to have a permanently flexible coating to resist cracking arising from expansion/contraction of long pipe runs.

Hydrotemp provides a unique solution

Tests carried out by independent accredited laboratory: Mild steel plates were sprayed with neutral salt spray and stainless steel plates were exposed to hydrogen chloride fumes.

The hydrotemp advantages:

• Easy brush application
• Permanently flexible
• Non-cracking
• -26°C to 204°C application range
• Water repellent
• Fast surface preparation
• Quick inspection available
• Safe to use
