Paip berlapis seramik

Paip berlapis seramik adalah penggunaan SHS – Pembuatan sentrifugasi, takat lebur paip seramik alumina masuk 2045 ℃, lapisan alumina dan struktur lapisan keluli kerana proses sebab-sebab khas, medan tekanan juga istimewa. Pada suhu bilik tekanan mampatan lapisan seramik, tegasan tegangan oleh lapisan keluli, the two opposites, into a balanced whole. Only the temperature rises above 400 ℃, both due to the thermal expansion coefficient is not the same, the new stress field generated by the thermal expansion of the ceramic and steel in the presence of the original stress field cancel each other, so that both the ceramic layer and the steel layer is in free equilibrium. When the temperature rises to 900 ℃ Ling ceramic lined steel pipe placed inside the water, repeated immersion times, the composite layer does not crack or split, showing ordinary ceramic unparalleled thermal shock resistance. This performance in the construction of great use, because of its outer layer is made of steel, coupled with the inner temperature does not crack in the construction of the flange, purge port, explosion-proof doors can be welded directly to the welding method can also be used connection, than wear and cast stone pipe, wear steel pipe, wear-resistant steel rare, double metal composite pipe, paip keluli, steel rubber tube in the construction can not be easily welded or soldered better. Ceramic Lined resistance to mechanical shock resistance or, in between the transportation, installation and beat two brackets weight bending deformation, not broken off the composite layer.

Ceramic-lined pipe with traditional steel, wear-resistant paip keluli aloi, cast stone and steel-plastic pipe, steel pipe and other rubber has essential difference. Ceramic outer layer is steel pipe inner corundum. Corundum layer up to 100-1500 kekerasan Vickers (Rockwell hardness of 90-98), the equivalent of tungsten-cobalt hard gold. High wear resistance than paip keluli karbon lebih daripada 20 kali, it is much more superior than the usual adhesive wheel made of corundum performance. Now is still a variety of corundum grinding wheel grinder cut hardened steel main wheel. Ceramic pipe layer in the corundum corundum grinding wheel wear out. Wear-resistant ceramic pipe corundum mainly by a few millimeters thick inner layer, the Mohs hardness of 9, second only to diamond and silicon carbide, oxide in all, it is the highest hardness.

Ceramic-lined pipe with high wear resistance, anti-hakisan ability fluid. In a wind pipe, pipe wear fastest, ceramic-lined steel pipe elbow thick abrasion wear resistance than steel elbow is more than 5 kali.
