Storage Tank Sampler

In the petrochemical, energy storage and transportation, and grain and oil processing industries, the safe, accurate, and efficient sampling of liquids in large storage tanks is a core link to ensure product quality, trade fairness, and process control. The HCYG Series Storage Tank Sampler developed by Hubei Wan'an Environmental Protection & Petrochemical Equipment Co., Ltd. is a revolutionary solution designed specifically for such harsh demands. It completely subverts the dangerous mode of traditional manual tank-climbing sampling. Through precise mechanical linkage and an off-tank closed operation box, it realizes accurate and rapid sampling of oil at any liquid level inside the tank from a safe position under the tank. It is a standard configuration for modern tank farms to achieve intrinsic safety, improve management efficiency, and enhance data reliability.

Core Functions & Superior Performance

This product strictly complies with industry standards such as GB/T4756-2015 "Manual Sampling Method for Petroleum Liquids" and SH/T3414-2017, and is specially designed for vertical storage tanks (dome roof tanks, internal/external floating roof tanks). Its core lies in a set of precise in-tank proportional sampling mechanism: through the float ball or floating disc rising and falling synchronously with the liquid level, the sampling point is driven to automatically track strictly according to the proportion of 5/6 (upper part), 1/2 (middle part), and 1/6 (lower part) of the liquid level height, ensuring that the theoretical error of the sampling point is less than 1%. All samples are led to the off-tank fully closed operation box through independent pipelines. Operators can safely and conveniently obtain highly representative upper, middle, lower single-point samples or proportional mixed samples in the box without climbing the tank.

Key Customer Value

Intrinsic Safety & Risk Elimination: It completely eliminates major safety risks such as high-altitude falls, slips, and exposure to toxic and harmful gases (such as VOCs and hydrogen sulfide) caused by operators climbing the tank. The off-tank closed operation box design ensures no leakage or volatilization during the sampling process, fully meeting the requirements of environmental protection regulations for VOCs leakage control, and protecting personnel health and environmental safety.
Precise Sampling & Reliable Data: The proportional mechanical structure based on geometric principles has a sampling point accuracy of 98.5%-101.5%, far exceeding the accuracy of manual visual positioning. It can ensure that the obtained samples truly represent the overall quality of the oil in the tank, providing indisputable authoritative data for trade settlement, quality inspection, and process adjustment.
High Efficiency & Convenience, Time & Labor Saving: Traditional two-person tank-climbing sampling takes nearly 1 hour, while using the storage tank sampler only requires one person to complete all sampling operations under the tank within 5 minutes, greatly improving work efficiency and reducing labor intensity. It is not affected by severe weather such as rain, snow, and strong winds, realizing all-weather operation.
Wide Adaptability & Flexible Selection: The product series is complete, providing various models such as HCYG-I (dome roof tank), HCYG-K (floating roof tank), HCYG-X (general type), HCYG-H (tank without stirring), and HCYG-D (tank with stirring), perfectly adapting to different tank types and internal structures. The applicable media cover naphtha, gasoline, diesel, crude oil, wax oil, asphalt, and various chemical raw materials. It can even be customized with food-grade materials for sampling grain and oil products such as edible oil.
Optimized Structure & Easy Maintenance: The closed large-pipe type support rod or steel cable force reduction design is adopted, which greatly reduces the pull force on the floating disc (can be reduced to less than 10% of traditional products), avoiding the risk of disc jamming and tilting. The integrated design of the off-tank operation box, with reasonable layout of valves and pump sets, makes installation, commissioning, and daily maintenance extremely convenient.

Typical Application Scenarios

National strategic petroleum reserves and commercial oil depots: Daily quality monitoring and trade handover sampling of crude oil and finished oil storage tanks.
Refineries and chemical plants: Process control and quality inspection sampling of intermediate raw material tanks and product tanks.
Grain and oil storage tanks: Sanitary and safe sampling of edible oil, palm oil, and other grain and oil products.
Any vertical liquid storage tank that needs to replace dangerous and inefficient manual tank-climbing sampling to achieve safe, precise, and efficient management.
