Ceramic lined pipe properties

Wear-resistant ceramic composite pipe, full name ceramic liner composite steel pipe, is a kind of ceramic composite steel pipe.

Ceramic (Corundum: a-Al2O3) lined abrasion resistant straight pipe and fittings are lined with highly abrasion resistant ceramic by SHS -------Self-propagating High-temperature Synthetic process.

A small amount of iron also remains in the ceramic layer. There is a thin equiaxed grain area of alumina near the steel pipe wall, and then alumina was grown in form of dentrite to the surface of ceramic layer.

When abrasive material is transported through steel pipe in mining applications, typically as pumped slurry, the pipe can quickly be eroded from the inside out, which in more extreme cases can result in pipe leaks and even failure, or significant maintenance costs and downtime for pipe replacement.

Mechanical Propertie
FeAl2O4 distributes among alumina dentrite. Although the ceramic layer was solidified from one end to another end of a pipe, the microstructure of ceramic layer was almost uniform throughout the whole length of the pipe.
Hoop Strength

Hoop strength is the resistance against radial pressure. The strength of the ceramic -lined steel composite pipe is 300 to 500MPa.

Compression-Shear Strength

Compression-shear strength is the bonding strength at the interface between the ceramic layer and the steel pipe. The compression-shear strength of the ceramic-lined composite pipe is 15 to 20MPa.

Resistance to Mechanical Shock

The ceramic layer does not crack or flake off when the composite pipe receives a mechanical shock.

Resistance to Thermal Shock

The ceramic layer does not crack or flake off when heated to 800℃ and then quenched.
The relative weight of the composite pipe is about
40-50% lighter than that of the caststone pipe

Six performance summary of the composite pipe of the ceramic composite pipe 1, good wear resistance Ceramic composite pipe with inner liner for ceramic corundum (a-AL2 (subscript) O3 (subscript, similarly hereinafter), Mohs hardness can reach 9.0 rather than hrc90. Therefore, the grinding medium of all industries are highly resistant to wear. The industrial operation confirmed: its wear life is ten times the quenching steel or even dozens of times. 2, running resistance: Ceramic composite pipe due to the smooth surface of the inner surface is better than any metal pipe, water resistance coefficient of 0.0193, slightly lower than the seamless tube. 3, corrosion resistance, anti fouling: Since the ceramic layer is (a-AL2O3), it is a neutral material. Therefore has the acid alkali and water resistance, and at the same time with anti - scale and so on. 4, heat resistance and heat shock resistance performance is good: As the corundum ceramic (a-AL2 (subscript) O3 (subscript)) is a single st

Sleeve Type Expansion Joints

Sleeve Type Expansion Joints are primarily designed to compensate for thermal expansion but it is not the only movement being imposed on the pipeline system. Other types of movements can occur that need to be taken into account when providing a pipework flexibility solution such as building settlement, wind loading, vibration from rotating and reciprocating machinery. Related Ceramic lined pipe Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique. The sleeve type expansion joint is also called tube compensator, pipe expansion joints, which is used for hot fluid pipelines, mainly applied to the laying of straight pipelines. And the working medium can be hot water, steam, oil, etc. The sleeve expansion joint does thermal expansion by sliding its external sleeve. Sleeve compensator Types of Sleeve Type Expansion Joint: Buried sleeve expansion joint: Using advanced sealing structure and sealing materials with the features of easy installation&
