Large Bore Calcium Silicate Pipe Section For Power Plant Steam Line Insulation

MYREAL power plant pipe insulation uses calcium silicate sections specified for main steam, hot reheat and feedwater lines in generating plants. Because the material carries a super low chloride ion content, it is suited to stainless and alloy steel pipework in thermal, nuclear and combined cycle plants, where chloride stress corrosion is a design concern.

Technical Data

Application

Used on main steam, reheat, extraction and feedwater piping in thermal power, nuclear power, hydroelectric and combined cycle plants.

• Main steam and hot reheat piping insulation
• Turbine extraction and feedwater lines
• Nuclear power plant auxiliary piping insulation
• Combined cycle HRSG connecting pipework
• City heat supply main and high pressure headers

Key Advantages

• Super low chloride ion content, suitable for stainless and alloy steel lines.
• Rigid section holds a concentric thickness on large bore high pressure piping.
• 0.081-0.087 W/(m.K) at 300 C supports plant heat rate targets.
• Resists vibration and thermal cycling on turbine and pump connections.
• Class A1 non-combustible for turbine hall fire safety requirements.

Standards and Compliance

• Manufactured to GB/T 5486 calcium silicate products standard under an ISO 9001 certified quality system
• GB/T 8624 Class A1 non-combustible, no flame spread and no dense smoke
• Super low chloride ion content protects stainless steel and alloy pipework from chloride stress corrosion
• Low water absorption, performance is not affected by humidity
• Free of formaldehyde, benzene and other harmful substances
• Special shaped parts can be customized to your drawing

Installation Notes

• Install half-sections with circumferential joints staggered between layers.
• Clamp with stainless steel bands at 300 mm pitch on vertical lines.
• Fit expansion joints at the spacing defined in the insulation design.
• Clad with aluminum or stainless steel sheet in turbine hall areas.
