Wholesale price of ceramic wear-resistant elbow - market quotation - supplied by manufacturers

  Wholesale price of ceramic wear-resistant elbow - market quotation - manufacturer supply , Ceramic wear-resistant elbow is manufactured by thermite centrifugal method
The pipe is composed of corundum ceramic, transition layer and steel pipe from inside to outside
The ceramic layer forms dense corundum ceramic (Al2O3) at a high temperature above 2200 ℃, and forms a firm combination with the steel pipe through the transition layer
Ceramic lined composite steel pipe has good comprehensive properties such as wear resistance, heat resistance, corrosion resistance, mechanical shock and thermal shock resistance, and good weldability
(hereinafter referred to as ceramic pipe) I
good wear resistance
The inner lining layer of ceramic pipe is corundum ceramic (Al2O3), and the hardness of ceramic layer is HV & Ge; 1000, ceramic layer density & Ge; 3
4g/cm3, crushing strength and rigidity ≥ 280MPa。 2、 The inner layer of the ceramic pipe with small running resistance shall have a smooth, flat surface and no peeling
The roughness of the inner surface and the resistance characteristics of clean water shall be tested by a professional testing unit, and the cleaning resistance coefficient shall be less than 0
0193, and the test report shall be issued
3、 Corrosion resistant and anti scaling ceramic layer has acid and alkali corrosion resistance and acid resistance ≥ 80%, and has the characteristics of anti scaling at the same time
The crack of ceramic layer can be tested by electrochemical nondestructive testing of high resistance lining, and the steady-state current is I & le; 70ma / m2, deposition time t≥ 20min。 4、 Good temperature resistance and thermal shock resistance
The ceramic pipe can operate normally for a long time in the range of - 50 ℃ - 100 ÷ degrees, and the material has good thermal stability
5、 Ceramic wear-resistant composite steel pipe is a kind of composite pipe that organically combines ceramics and metals
Ceramic steel pipe combines the advantages of high hardness of alumina, good chemical inertia and steel
It has excellent wear-resistant, corrosion-resistant, heat-resistant, thermal shock resistance and mechanical shock resistance
It is used in pulverized coal, ash, mine powder, tailings, backfill, coal mine and concentrator of power plant The service life of coke particles in coking plant and materials in sintering plant is more than 15 times longer than that of ordinary steel pipe
It can also be used for the transportation of liquid aluminum and corrosive media
