The sampler for oil products: designation and classification

In the oil industry great attention is paid to quality control. To determine the most important quality of liquid fuel required sampler for oil – the device through which the sampled product preservation conditions of samples.

Presents the means and devices used in the field to obtain samples from the wells, and for removal of samples from various tanks – tanks, pipelines, technological colon, to check storage conditions. To obtain the most reliable result, all the work is carried out by specially trained personnel.

Assignment samplers

Any enterprise whose activities are closely linked to oil or oil products, the necessary samplers. Their main purpose-the removal of samples from storage sites or transportation. The samples are then subjected to multilevel analysis. Based on the results of laboratory tests determine that the product meets the requirements of GOST and other normative documents.A Modern sampler for petroleum products shall be manufactured in accordance with the requirements set forth in GOST Р15150-69. The vast majority of devices are designed to operate at temperatures from -40 to +50 degrees Celsius and with average kinematic viscosities up to 11 cSt.

Types of samplers according to the appointment

Today, samplers are complex devices that differ from each other characteristics and area of application. According to the design concept, all devices for withdrawal of the samples can be divided into the following groups:

1. Bottom sampler for oil withdraws samples only from the bottom or near the bottom of the space.
2. Pinpoint the device that withdraws samples of the product in a particular place or at a specifically set time, most commonly used in pipelines.
3. Multi-level devices can take samples simultaneously at several points, is often used in oil bases, filling stations.
4. Automatic devices, which are necessary for automatic collection of samples with the passage of the product through the pipeline.
5. Sectional samplers represent a fixed installation with a number of sections, which are installed in vertical tanks.

Any sampler consists of two nodes-the reception chamber, which takes samples of product and controls which opening of the valve allows to flow the fluid inside the reception chamber.

Classification of devices according to the design

There Are also samplers for petroleum products, portable and stationary.The First type of equipment is used for withdrawal of samples from the mobile stores. Fixed devices are often used in large enterprises, which operate with large volumes of oil and its products. They, in turn, are divided further into several varieties:

1. Integrated, forming an average sample, which is selected from each layer.
2. Portions, which provide the samples taken from different points, located at the height of a column of the substance.
3. In batches-integrated – the average sample is derived from multiple samples taken at different levels.

Portable devices represent a vessel of cylindrical shape, made of not forming the sparks of steel with long-lasting anti-corrosion coatings. Any portable sampler for oil products has a lid with an air valve and a PTFE stopper with a hole. In the hole of the tube fixed stock that holds a metal cable.

Types of drives samplers

Any sampler for sampling of petroleum products is equipped with either an automatic or manual mechanism for unlocking.

In any case, the removal of samples is conducted at the behest of the operator. In automated devices, the locking device may be subject to three types of privodov:

1. Elektricheskom.
2. Elektromagnitnom.
3. Pnevmaticheskim.

The First two types can have a remote or analog control, and the valve operates at the behest of the actuator or in accordance with the instructions of the electromagnet. A pneumatic sampler withdraws for petroleum products sample to achieve a certain depth where the pressure reaches the set value.
