Packing of DEG
Diethylene Glycol (DEG) is typically packed and transported in various types of containers and packaging materials to ensure safe handling and storage. The packaging of DEG depends on its intended use, volume, and mode of transportation. Here are some common methods of packing DEG:
Drums:DEG is commonly packed in steel drums or plastic drums. The standard size of these drums is usually 55 gallons (approximately 208 liters). Drums are suitable for smaller quantities of DEG and are easy to handle and transport.
Intermediate Bulk Containers (IBCs): For larger quantities, DEG may be packed in IBCs, which are large containers with capacities ranging from 275 gallons (about 1,041 liters) to 330 gallons (about 1,249 liters). IBCs are designed for bulk transport and storage and are often used in industrial settings.
Tank Trucks and Railcars:When large volumes of DEG are required, it can be transported in tank trucks or railcars. These vehicles have specialized containers with high capacities to transport large quantities of liquids safely.
Isotanks:Isotanks are large, cylindrical containers designed for intermodal transport. They can hold a substantial amount of DEG and are used for international shipping and long-distance transportation.
Flexitanks:Flexitanks are flexible containers made of multiple layers of polyethylene, which can hold up to 24,000 liters of liquid. They are commonly used for the transportation of liquids, including DEG, via sea or land, as they provide a cost-effective alternative to traditional shipping containers.
Delivery time and Readiness of DEG
The delivery time and readiness of Diethylene Glycol (DEG) can vary depending on several factors, including the supplier, location, quantity ordered, and the current market conditions. Here are some factors that can affect the delivery time and readiness of DEG:
Supplier Location:The distance between the supplier's location and the delivery destination can impact the delivery time. Suppliers closer to the delivery location may offer shorter delivery times compared to those located farther away.
Production Capacity:The production capacity of the DEG manufacturer can influence the readiness of the product. Suppliers with larger production capacities may have a more readily available supply of DEG.
Inventory Levels:The supplier's inventory levels can also affect the readiness of DEG. Suppliers with higher inventory levels are more likely to have the product readily available for immediate delivery.
Demand and Order Volume:High demand or large order volumes may lead to longer delivery times, especially if the supplier needs to produce or procure additional quantities of DEG to fulfill the order.
