GB/T 9109.3-2014Dynamic measurement of petroleum and liquid petroleum products—Part 3: Technical requirements of installation for pipe prover (English PDF)

Foreword

GB/T 9109 is divided into four parts.

--- GB/T 9109.1 Dynamic measurement of crude oil general principles;

--- GB/T 9109.2 Oil and dynamic measurement of liquid petroleum products - Part 2. flowmeter installation technical requirements;

--- GB/T 9109.3 dynamic measurement of oil and liquid petroleum products - Part 3: Volume tube mounting technical requirements;

--- GB/T 9109.5 Petroleum and liquid petroleum products - Calculation of oil dynamic measurement. This part of GB/T 9109 Part 3: This section drafted in accordance with GB/T 1.1-2009 given rules.

This Part replaces GB/T 9109.3-1988 "Dynamic measurement of crude oil fixed standard volume tube mounting technical requirements." This portion

GB/T 9109.3-1988 compared to the main changes in the technical content is as follows.

--- The standard name changed to "oil and liquid petroleum products dynamic measurement - Part 3. Volume tube mounting technical requirements";

--- Modify the scope, increase in oil and liquid petroleum products;

--- Modify the standard structure, an increase in Chapter 3;

--- Increasing the density meter tube import volume requirements to install filters;

--- Increase the requirements for the import and export volume of the tube temperature, pressure meter accuracy and installation position;

--- Increasing the volume of the tube outlet is calculated minimum backpressure;

--- Selection requirements increased volume of the tube;

--- Increasing the volume of one-way and two-way volume of tube pipe installation procedures;

--- Remove the imported contents of the installation of a small volume prover.

1 Scope

GB/T 9109 provisions of this part of the design of oil and liquid petroleum products dynamic volume metering pipe system design, installation, construction and acceptance skills requirement.

This section applies to petroleum and liquid petroleum products as the working medium volume line pipe fixed installation, the central station test tube volume, shift Acting prover can refer to use.

3 General requirements

3.3 meters - for the transfer test tube volume, the repeatability should be better than 0.02%.

3.4 volume pipe system design should be based on the selected flowmeter type, nominal diameter, number of units and other factors to consider, at an affordable original Choose fixed installation or mobile prover volume tube.

3.5 and meet the technical requirements under the premise of the overall arrangement, the volume of pipe installation system should ensure a stable flow pattern, the volume of pipe system layout, Fire safety should be consistent with the relevant provisions.

3.6 volume pipe system design, including design of the installation process, the water flooding method verification systems and auxiliary systems.

3.7 volume tube design system should meet the volume of pipe installation, operation, operation and maintenance requirements to ensure stable performance measurement system, accurate and reliable.

3.8 according to the geographical and climatic conditions, determine the volume of the tube is installed indoors or outdoors, and take appropriate measures to maintain the ambient temperature, at full Foot Prover operating environment requirements. Northern cold areas should be installed indoors; in the south can be installed outdoors, but avoid direct sunlight. body Plot of control system should be set up in the control room of the explosion and fire.

3.9 volume tube should be used to sled the whole supply, the factory certified by; split supply disassembly should be qualified and then boxed in factory test.
