Heating Pad
Place the heating pad at the bottom of the flexitank and heat it to keep the chemicals inside the flexitank in a certain state.
The steam heating pad is a rubber tube installed at the bottom of the container flexitank, and the steel pipe is used to introduce and export steam, so that the steam flows at the bottom of the flexitank and plays a role in heating the liquid inside the flexitank through heat conduction. It has the characteristics of simple structure, high thermal efficiency and no harm to the liquid bag.

Steam Heating Pad Heating Efficiency And Heating Temperature
specific parameters: Take the 32-tube steam heating pad as an example
| Environment temperature | -10℃-20℃ | |||
| Steam pressure | 0.5Mpa | |||
| Heating liquid | Water | Oil | ||
| Weight | 24 Ton | 24 Ton | ||
| Heating efficiency | About 0.6℃/H | About 1.2℃/H | ||
| Explanation | 1. Due to the different night temperature differences, the heating rate during the day is significantly higher than that at night. Heat dissipation has a greater impact on heating efficiency. | |||
| 2. According to the heat calculation formula: Q=c*m*AT provides the same heat, and the same temperature rise is inversely proportional to the specific heat and mass of the liquid. From this, we can indirectly estimate the heating rate of other liquids with different specific heats and masses based on the specific heat of water 4.2 and the mass of water 24 tons. For example, the specific heat of a certain grease is 2.3 and the density is 0.86. If heated under the same conditions, the temperature will rise. The efficiency is increased by approximately 2.12 times. | ||||
| 3. Due to different usage areas, usage conditions and heating materials, the heating potential and heating efficiency will be different. The above indicators are for reference. | ||||
Specific Experimental Parameters
| Conditions | Gas supply station pressure of 0.5Mpa | Open-air heating | ||
| Explanation | 1. It may be necessary to preheat the entire system at the beginning of the heating stage, the temperature rise is slow, and the steam valve is not fully opened on the first night. It was also found that the steam volume was significantly reduced, which was related to the gas station. | |||
| 2. When the steam valve is fully opened during the day the next day, the efficiency is significantly improved by 0.5℃/H. The next night it was at 0.42℃/H. Temperature rises faster during the day than at night. | ||||
| 3. The average day and night temperature rise is 0.46℃/H. | ||||
| 4. According to the heat calculation formula: heat = specific heat * mass * temperature difference, the specific heat of water = 4.2, density = 1. For example, the specific heat of heating oil is 2.3, and the density is 0.83. The estimated heating time is about 1℃/H ( day and night average). | ||||
Flexitank is a soft packaging container made of polyethylene (PE) and polypropylene (PP) that can store and transport various non-hazardous fluids. Each set of flexitanks can be placed exactly in a 20-foot container, with a volume of 15m³-26m³. In the transportation of non-hazardous liquid materials, it can replace expensive traditional packaging such as oil tankers and iron drums. It takes about 20 minutes to install a set of flexitanks. After the installation is completed, you only need to connect the valve and the feed port to load materials. After the loading is completed, the fully loaded container can be transported on roads, railways, and freighters for medium and long distances.
Features
Low purchase cost, high load capacity, light weight and small size of the product.
Effectively reduce costs (including packaging, barreling, storage, processing and material management costs), only need to pay one-way freight, reduce transportation costs, no cleaning costs, eliminate the risk of cross-contamination of goods.
Easy operation, reliable quality, environmentally friendly products, simplified loading and unloading procedures, reducing loading and unloading workload, and effectively improving work efficiency.
Product Advantages
Abundant supporting resources: Containers are widely distributed in railways, ports, and highway freight yards. The quantities are huge and can be called at any time. However, the number of tank containers or tank trucks is relatively small and requires deployment, leaving little room for choice.
1
Hygienic and pollution-free: The flexitank is a disposable product and is made of imported food-grade raw materials. It does not cause secondary pollution to the liquid contained and can effectively maintain product quality.
2
Convenient transportation: The use of flexitank containers for transportation facilitates the implementation of rapid intermodal transportation by road, rail, and sea, and a door-to-door one-stop transportation mode, which greatly improves transportation efficiency.
3
Cost savings: Disposable products save cleaning, maintenance and other costs, and greatly save manpower and financial resources during the loading and unloading process.
