1 Piece Threaded Ball Valve Can Also Be Used In The Chemical Industry

1 Piece Threaded Ball Valve also prove useful in the chemical industry.

Precautions for Stainless Steel Ball Valves

1. Rinse the stainless steel ball valve thoroughly while it is fully open.

2. After connecting the stainless steel ball valve to the pipeline, cross-tighten the flange bolts to the specified torque.

3. Before connecting the stainless steel flange ball valve to the pipeline, remove any remaining impurities from the pipeline.

4. During installation, do not use the actuator of the ball valve as a lifting point to avoid damage to the actuator and accessories.

5. Cast steel flange ball valves should be installed horizontally or vertically on the pipeline.

6. Pipelines near the cast steel ball valve installation point must not be allowed to sag or be subjected to external forces. Use pipe supports or other supports to eliminate pipeline deviation.

7. Before installing the ball valve, perform a complete system test according to the specified signal. Only after passing the test can it be installed online.

In the soda ash production process, ammonia mother liquor II and carbon dioxide are carbonated in a carbonation tower to produce a NaHCO3 suspension. The mother liquor after cold precipitation is then salted in a salting-out crystallizer to further precipitate ammonium chloride slurry. The salted-out mother liquor undergoes heat exchange, ammonia absorption, and clarification to produce qualified ammonia mother liquor II, which is then sent to process I. The slurry precipitated during the cold precipitation and salting-out processes is thickened, centrifuged, and dried to produce the ammonium chloride product.

Both soda ash and ammonium chloride production processes present long process flows, high system mother liquor temperatures, and complex stainless steel ball valve components, including ammonia and high chloride ions. The mother liquor after vacuum filtration is sent to process II, where the filter cake is calcined to produce the soda ash product. In the ammonium chloride production process, the mother liquor from the vacuum filter absorbs ammonia and undergoes heat exchange before precipitating ammonium chloride slurry in the cold crystallizer. This slurry also contains a certain amount of calcium and magnesium solids. This can lead to severe corrosion and wear of equipment and piping, especially during environmentally friendly waste treatment, resulting in frequent equipment failures and maintenance. Therefore, improving the corrosion and wear resistance of equipment is crucial for safe and stable operation. Valves, as fluid control components, are particularly vulnerable.
