I. Product Introduction
Crude oil sampling equipment is a specialized set of tools and systems designed to collect representative, accurate, and uncontaminated samples of crude oil during exploration, production, transportation, storage, and refining processes. Its core function is to provide reliable sample basis for subsequent quality testing, component analysis, and trade settlement—key links that directly affect crude oil pricing, processing efficiency, and compliance with industry standards.
Widely applied in oil fields, oil depots, pipelines, tankers, and refineries, this equipment adapts to diverse working environments, including high-pressure wellheads, low-temperature storage tanks, and mobile transportation scenarios. Unlike ordinary sampling tools, it integrates sealing, pressure regulation, and anti-contamination technologies to address the unique properties of crude oil, such as high viscosity, high sulfur content, and the presence of impurities (e.g., sand, water, and sediment). By ensuring sample representativeness, it effectively avoids sampling errors that could lead to economic disputes or processing risks.
II. Product Features
-
High Representativeness of Samples: Adopts multi-point sampling design (e.g., top, middle, and bottom sampling ports for tanks, or inline sampling nodes for pipelines) and complies with international standards such as API MPMS 8.1 (American Petroleum Institute) and ISO 3170. The sampling process strictly controls the sampling flow rate and frequency to avoid bias caused by uneven crude oil composition (e.g., water stratification or sediment accumulation). For high-viscosity crude oil, optional heating and stirring auxiliary modules further ensure uniform sample collection.
-
Strong Corrosion and Pressure Resistance: The key sampling components (sampling probes, valves, and sample cylinders) are made of high-quality corrosion-resistant materials, such as 316L stainless steel, Hastelloy, or titanium alloy. This enables the equipment to withstand the corrosion of high-sulfur, high-acid crude oil and adapt to working pressures ranging from vacuum (for storage tanks) to 100MPa (for high-pressure wellheads). The sealed structure of the sampling system prevents crude oil leakage and external contamination, ensuring operator safety and environmental protection.
-
Intelligent and Automated Operation: Equipped with PLC (Programmable Logic Controller) and touch screen control system, it supports automatic sampling based on preset parameters (e.g., time intervals, flow triggers, or liquid level changes). Some advanced models are integrated with sensors for real-time monitoring of temperature, pressure, and sample volume, and can upload data to a central control platform via 4G/5G or Ethernet. This reduces manual intervention, avoids human errors, and improves sampling efficiency—especially suitable for remote or harsh working environments.
-
Easy to Operate and Maintain: The equipment features a modular design, allowing quick assembly and disassembly of components such as sampling probes and filters. The touch screen interface provides clear operation guidelines, and fault self-diagnosis functions (e.g., clogging alarm, pressure abnormal prompt) help operators locate and resolve issues quickly. Additionally, the smooth inner wall of the sample cylinder and detachable filters simplify cleaning and maintenance, reducing downtime.
-
Good Compatibility and Customization: It can be matched with different auxiliary equipment, such as sample coolers (for high-temperature crude oil), degassers (for crude oil with high gas content), and sample storage cabinets. According to customer needs (e.g., specific sampling points, environmental temperature, or testing indicators), customized solutions can be provided—such as portable sampling kits for field exploration, or fixed inline sampling systems for long-distance pipelines.
