Package cover castable, ladle castable, Tianjian Brilliance

In actual use, according to the project required to allow the use of certain types of carbon fiber combined aggregate pouring one-rod stabilizer, below oil production accessories, including carbon fiber centralizer body, oily rod, carbon fiber body and the rod-time righting cast integrally. The utility model directly to the carbon fiber disposable centralizer body cast on a rod, carried out by the method of eliminating the original members of the media role, but also eliminates the need for workers in the field to go down the traditional centralizers repeat the installation time, solid pole high, while reducing the tedious parts, manufacture and installation is very easy, and light weight, and low cost, abrasion resistance is 1.8 times that of traditional centralizer body and improve the workover cycle, saving maintenance costs. Uncertainty refractories classification: a, divided according to construction methods castable, ramming material, plastic, gravity feed, spray paint b, divided according to harden way hydraulic, gas-hard, hot hardness c, press binders classification Water cement binding phosphate binding, sodium silicate combined with ultrafine (completely without cement) d, Material has high aluminum, alumina, mullite, silicon carbide, clayey, magnesia and other e, according to the performance points General project abrasion, acid and alkali uncertainty detected refractories factory: performance testing have bulk density, rate of change of line, compressive and flexural strength, chemical composition (aluminum, iron, silicon) wear, thermal conductivity, etc. . Ramming materials suitable for what position? Can be used for complex structure of the site should not be used formwork vibrated picks or mechanical ramming mass or less important part, can be hand-ramming.
