Material Performance

1. Mechanical property

: nickel material has good tenacity and stable bearing capacity. The flange cover is overall thick and not easy to deform and warp under long-term bearing capacity;

2. Anti-corrosion performance

: resistant to concentrated alkali, molten alkali and hydrofluoric acid medium, no galvanic corrosion with the whole set of nickel fittings;

3. Physical and chemical characteristics

: stable thermal conductivity, high temperature oxidation resistance, low air release under vacuum condition;

4. Application advantages

: good sealing performance, convenient maintenance and disassembly, long-term isolation of corrosive medium pipelines.

[ Process structure ]

1. One-body forging and one-piece molding, dense internal structure, no hidden dangers of air hole and interlayer leakage;
2. Precision turning of sealing surface, high flatness, and corrosion resistant gasket not easy to leak;
3. Vacuum annealing can eliminate the turning stress and avoid deformation and edge warping during use;
4. Dimensional tolerance standard, completely matched with nickel flange of the same specification, with strong interchangeability.

[ Application field ]

1. Chlor-alkali chemical

: end of caustic soda conveying pipeline and pipe orifice of storage tank are blocked;

2. Fluorine chemical industry

: spare nozzle isolation blind cover for hydrofluoric acid equipment;

3. New energy metallurgy

: pipe plugging accessories of electrolyte circulating nickel heat exchanger;

4. Electronic vacuum

: seal the reserved port of high-purity alkali gas equipment;

5. LABORATORY EQUIPMENT
