Structure of Ceramic-lined 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.


SHS- self- propagating ceramic composite pipe Features
1 , good wear resistance
Since the lining layer ceramic composite pipe corundum ceramics (a-AL2O3), Mohs hardness up to HRC90 equivalent of more than 9.0 . So for metallurgy, electric power , mining, coal transportation and other industries grinding media have high wear resistance. Confirmed by the industrial operation : it is ten times the wear life of hardened steel or even several times .
2 , running resistance
SHS ceramic composite pipe due to the smooth inner surface , and never rust, nor as seamless steel pipe inner surface of the convex spiral exists. After internal surface roughness of the test unit and water resistance characteristics of the test , the inner surface smoothness better than any metal pipes, clearing a drag coefficient of 0.0193 , slightly lower than seamless . Therefore, the tube has a running resistance and other characteristics , can reduce operating costs.
3 , corrosion-resistant , anti- fouling
Since the steel ceramic layer (a-AL2O3), a neutral character. So with acid and seawater corrosion resistant , and also has anti-scaling and other characteristics.
4 , heat resistance and good thermal performance punch Fou
Since the alumina ceramics (a-AL2O3), single crystal structure stability . Therefore composite pipe in -50 - the long-term normal operating temperature range of 700 ℃ . Linear expansion coefficient of 6-8 × 10-6/0C, about the pipe about 1/2 . A material having good thermal stability.
5 , low construction cost
Light weight ceramic composite pipe , affordable . Lighter than cast stone pipes with diameter 50% by weight ; 20-30 % lighter weight than the wear-resistant alloy tube , and the wear and corrosion resistance, long life because so hanger fees , handling fees, installation fees and reduce operating costs . By the relevant institute and construction and engineering unit project budget comparison , the tube and cast stone project cost considerably , compared with the wear-resistant alloy tube , down about 20% of the project cost .
6, easy installation and construction
As the light weight of the tube , and good welding performance. Thus can be welded , flanged , fast connection , etc., to facilitate construction and installation , and can reduce installation costs.
