Capacity selection and installation precautions for steel lined plastic storage tanks

Storage tanks are very important equipment in industrial production, mainly used to store various liquid materials such as chemicals, solvents, oil products, etc. The selection and installation of storage tank capacity are crucial for the production, operation, and logistics management of enterprises. Steel lined plastic storage tank is a common type of storage tank, which consists of a steel body and a lined plastic layer. It has the characteristics of corrosion resistance, hygiene, stability, and long service life, and is widely used in industries such as chemical, pharmaceutical, and food. This article will focus on the capacity selection and installation precautions of steel lined plastic storage tanks.

1、 Capacity selection of steel lined plastic storage tanks

1. Consider factors

When selecting the capacity of steel lined plastic storage tanks, enterprises need to consider the following factors:

a. The volume and properties of the liquid to be stored (such as corrosiveness, toxicity, etc.); b. Production demand and logistics status, including the quantity and nature of raw materials, intermediate products, and finished products required for production, as well as the convenience and stability of logistics; c. Investment costs and operating costs, including factors such as the purchase cost, installation cost, operation and maintenance cost, and service life of storage tanks; d. Requirements of regulations and standards.

2. Selection principle

The selection of steel lined plastic storage tanks should follow the following principles:

a. Applicability principle: The selected storage tank should meet the properties and volume requirements of the liquid to be stored; b. Economic principle: Under the premise of meeting applicability, the storage tank type and specification with better cost-effectiveness should be selected; c. Environmental protection and stability principles: The selection of storage tanks should consider environmental protection and stability factors. For example, the storage of flammable and explosive liquids should comply with relevant standard requirements, and the use of storage tanks should be stable.

3. Capacity calculation method

The calculation of the capacity of steel lined plastic storage tanks is mainly based on the following formula:

V = m1 + m2 + m3 +…+ mn

Among them, V is the total capacity of the storage tank, and m1, m2, m3, etc. are the masses of various materials.

2、 Installation precautions for steel lined plastic storage tanks

1. Basic Engineering Preparation

Before installing the steel lined plastic storage tank, foundation engineering preparation is required, including land leveling, foundation construction, etc. The foundation should have load-bearing capacity and be able to withstand the weight of the storage tank and the load during operation. In addition, the foundation should be able to prevent displacement or settlement of the storage tank during operation.

2. Tank transportation and lifting

Steel lined plastic storage tanks are usually large and heavy, so attention should be paid to stability during transportation and lifting. A detailed transportation plan should be developed before transportation, including transportation route, transportation mode, transportation time, etc. During the lifting process, professional lifting equipment and experienced operators should be used to ensure the stability and stability of the storage tank.

3. Tank installation

When installing steel lined plastic storage tanks, the following points should be noted: a The position and elevation of the storage tank meet the design requirements; b. Check whether the appearance and structure of the storage tank are intact and undamaged; c. Install and debug the storage tank according to the instructions or specifications; d. The inlet and outlet pipelines of the storage tank are connected correctly, unobstructed, and comply with relevant standard requirements; e. During installation, pay attention to protecting the plastic lining inside the storage tank to avoid damage or scratches.

4. Stability measures

During the installation process of steel lined plastic storage tanks, the following stability measures need to be taken: a Set up safety warning signs and isolation facilities at the construction site; b. Provide stability education and training to operators to enhance their awareness of stability and operational skills; c. Regularly inspect and maintain the storage tanks to ensure they are in good condition; d. During use, strictly follow relevant safety regulations to ensure the safety of personnel and property.

5. Environmental Impact Control

Steel lined plastic storage tanks may generate environmental impacts during use, such as odors, exhaust gases, etc. Therefore, the following points need to be noted during the installation process: a Install ventilation or exhaust vents around the storage tank to promptly release gas; b. Treat the exhaust gas and discharge it only after meeting relevant emission standards; c. Treat wastewater to meet relevant discharge standards before discharging it; d. Classify and treat solid waste, recycle recyclable materials as much as possible, and dispose of non recyclable materials properly.
