I. Product Overview
MDI storage tanks are dedicated high-risk anti-corrosion pressure-bearing storage tanks for the chemical, polyurethane, new material, and foam material industries, belonging to Class II pressure vessels. Mainly used for constant temperature, drying, and sealed storage of polymeric MDI, pure MDI, and isocyanate raw materials.
MDI has extremely high chemical activity and is very easy to react with water to generate carbon dioxide and scale precipitation, causing risks such as material deterioration, overpressure inside the tank, and pipeline blockage. Our company professionally customizes and produces high-precision constant temperature, nitrogen-sealed moisture-proof, sealed and explosion-proof MDI dedicated storage tanks, designed and manufactured in strict accordance with GB 150 and TSG 21 pressure vessel standards, suitable for long-term, stable, and safe material storage conditions in chemical enterprises, eliminating problems such as material moisture absorption and deterioration, self-polymerization crystallization, and abnormal pressure.
II. Core Product Advantages
1. Dedicated MDI Formula Design, Adaptable to High-Risk Chemical Media
Designed specifically for MDI's susceptibility to hydrolysis, self-polymerization, crystallization, and overpressure risks, completely different from ordinary tanks, providing safer storage and more stable materials.
2. Full Qualification Compliance, Can Be Supervised and Registered
Complete pressure vessel qualifications for the entire series, with flaw detection reports, pressure test reports, as-built documentation, and supervisory inspection certificates upon delivery, meeting chemical safety supervision and acceptance standards.
3. High Storage Stability, Greatly Reducing Material Loss
Dual guarantee of precise constant temperature + dry nitrogen seal, effectively avoiding material deterioration, scrapping, and scaling blockage, greatly reducing enterprise raw material loss costs.
4. Safe and Explosion-Proof, Zero-Hidden-Danger Operation
The entire system is explosion-proof designed, operates under slight positive pressure, with pressure interlock protection, eliminating overpressure, gas leakage, and chemical reaction overpressure risks, complying with chemical safe production specifications.
5. Durable and Easy to Maintain, Long Service Life
Inner wall polished to prevent adhesion, corrosion-resistant, not easy to scale; reasonable structure, convenient cleaning, overhaul, and maintenance, extremely low equipment failure rate.
