Versatile asbestos cement pipes

Asbestos cement pipe, length 4m, internal diameter 300mm

Asbestos cement pipes are made of high-grade cement reinforced by 10% -15% chrysotile. They are still in great grade in construction, electric cable pipes, and industries, for their good properties of long life span, low thermal conductivity, durability, high heat and acid resistance, ease of installation as well as affordability.

For different proposes, they can be divided into three types: non-pressure, pressure and cable pipes.

Non pressure pipe
Non-pressure asbestos cement pipe is often used in chimneys, drainage systems, wiring and construction fencing. 
Pressure-free pipes comes with the diameters of 100, 150, 200, 250, 300, 400 , 500 mm and lengths of 3950 and 5000mm.

Asbestos cement pressure pipes at the construction site

Pressure pipes are available in diameters of 100, 150, 200, 250, 300, 400, 500mm and lengths in 4000, 5000 mm.

Cable protective pipe
Asbestos cement cable protective pipe is characterized by high heat resistance (1500℃), good heat dissipation, acid and alkali resistance, non-magnetic, smooth wall with the friction efficient less than 0.3, and easy machinability. When laid under the earth, electric cable pipe will be hardened by the humid earth and its strength will be raised. Its service period can reach 100 years. Three classes cable protective pipes are at stock - Class A, Class B, and Class C.

1. Class A: (inside diameter * wall thickness) - 100*10mm, 125*10.5mm, 150*10.5mm, 175*12mm, 200*13mm; Length - 4000mm; designed as concrete encapsulation laying.
2. Class B: (inside diameter * wall thickness) - 100*11mm, 125*14mm, 150*14mm, 175*14mm, 200*15mm; Length - 4000mm; available for direct buried installation of sidewalks and green belts.
3. Class C: (inside diameter * wall thickness) - 100*14mm, 150*16mm, 200*16mm; Length - 4000mm; for areas where overloaded vehicles go through, such as highways, secondary roads
