Points to discuss with the manufacturing company when purchasing glass-lined equipment
Thread Content
After selecting the glass-lined equipment manufacturing company, it is necessary to communicate with the company’s design staff regarding the specific operating conditions and process requirements of the equipment needed, and to make adjustments to the design so that the purchased equipment meets the production needs. The matters that need to be discussed are as follows: 1. Porcelain glaze and steel plate materials, as well as the corrosion resistance of the porcelain glaze; 2. Whether current standards or obsolete standards should be used; 3. Whether the mixing and heat exchange efficiencies can be improved; 4. The type of jacket, the width of the jacket flow channels, and the degree of jacket corrosion; 5. Double-pivot reduction or single-pivot reduction; 6. Whether temperature differences, liquid levels, and pH values can be measured automatically; 7. Connectors and the loads on them; 8. The uniform thickness of the metal; 9. Whether the thicknesses of the head and the cylinder are different, and whether they are connected with equal thicknesses; 10. Reinforcement for the openings in the tank cover and the tank body; 11. Calculation of strength under internal pressure; 12. Processes such as shaping, welding, surface treatment, and enameling; 13. Whether the firing process involves high-temperature rapid firing or low-temperature prolonged firing; 14. Control of tolerance variations; 15. Inspection, transportation, and after-sales service
“2. “Are it the current standards or obsolete standards?” – There’s no need to discuss this; in terms of design, it’s obvious that the current standards must be followed. Otherwise, it means the designers have failed in their duties (those responsible for standardization among designers are entitled to verify whether the current standards are being adhered to). 7. Loading conditions during takeover; 8. Uniform thickness of metal; 9. Whether the thicknesses of the end caps and the cylinder body differ, and whether they are connected with equal thicknesses; 10. Reinforcement of the tank lid and openings in the tank body; 11. Calculation of strength under internal pressure – These are all factors that designers must take into account. Designers are responsible for the overall quality of the equipment’s design, and this responsibility is quite significant. Owners don’t need to worry about this either, as designers won’t dare to cut corners. Their primary concern is always the safety of the equipment, as this is directly related to their own safety. Designers won’t skimp on quality just to save money for their employers – no one wants to face legal troubles or end up in prison. As for other issues, it’s necessary to consider the manufacturing capabilities of the enamel manufacturing plant. It’s important to determine whether certain structures and pipe sizes are feasible and can be manufactured. Designers need to carefully review everything in light of the production processes involved in manufacturing enamel-coated equipment, as owners may not be familiar with these processes. Therefore, some requirements might be unreasonable, and designers are responsible for explaining them clearly and finding alternative solutions for clients
You are absolutely right, but in reality, few chemical companies communicate with manufacturing firms. The equipment purchased by users is standard equipment – it’s installed as it is, and whether its design is appropriate or suitable for the requirements can only be determined after it’s put into use.
