Basra is both a state capital and a state of Iraq. The largest field in the state is the Rumaila field, a huge field as documented in the second reference.
Not only is there variation of properties from field to field, but also well to well within the same field. Therefore, the oil is divided into Basra light, medium and heavy. A Basra blend is about 31.5 degrees API. The sulfur content is 1.95%. I couldn't find more specifications on the internet.
Variations will also occur over time, as the less desirable heavy crude is usually produced later in the life of the fields.

What is the difference between astm 105n and astm a350-lf2?
ASTM A105 - For ambient- and higher-temperature service in pressure systems. ASTM A350 - intended primarily for low-temperature service and requiring notch toughness testing.
Reid vapor pressure of water?
Depends on temperature. For ASTM D323 the RVP of water is ~49.5 mmHg (torr) gauge or ~809 mmHg absolute (assuming standard pressure). FYI - ASTM D323 is measured at 100F.
Is astm material p91 martensitic steel or austenitic steel?
P 91 is a martensitic steel.
What is ASTM distillation?
This is one of the testing methods for gasoline and is also called Engler distillation. The whole method is based on the determination of boiling point by performing batch distillation. Boiling point is important for the safety and performance of solvents and fuels. It gives the composition, properties and behavior of fuel. Carrying out batch distillation also determines the volatility which majorly shows the tendency of hydrocarbons to produce explosive vapours. This also tells us the application in different industries depending upon the various temperature behavior of the fuel. Boiling point according to the standards limits distillation based on the product specification.
What is Hardgrove grindability index?
The Hardgrove Grindability Index was developed in the 1930s from experimental work by R. Hardgrove to determine the relative difficulty of reducing various coals to a particle size required for efficient combustion in pulverized coal boiler furnaces. The HGI is now commonly applied to specifications for coal to be used in the iron making, cement and chemical processes. There are several different "standard" methods for the determination of HGI (e.g. - AS1038 Part 20:2002, and ASTM D409-2006), which can lead to significantly different results. Further, HGI is an empirical measure and not a physical proprty of coal; as such the results of any standard test have relatively low repeatability for a given coal sample. In general, the higher the HGI value, the more readily a coal can be reduced to smaller particle sizes.
What test is used to evaluate fracture resistance of materials subjected to impact loads?
Using the (ASTM E 23) formal specification of impact - strength limits standards for Metals Impact testing is performed by using both the Charpy and Izod testers, both of these use the good old fashioned swinging pendulum method. For Cast Irons the (ASTM A327) specification are used. For electrical insulating parts and plastics the (ASTM D256) specifications can be used. For Tool steels the Torsion -Impact test method is employed. Using the Hatt-Turner tester with the (ASTM D143) specifications for different kinds of woods. For the American Railway Engineering System for the Axles used on trains the repeated drop tests are required to follow the (ASTM D143) specifications.
What is inclusion rating and its method?
Inclusion rating is a measurement of Impurity in any steel / alloy elements.. one of the STD for method of evaluation is ASTM E45.. MSQ Inclusion Rating is designed to produce ASTM E45 Method A and Method D inclusion ratings for inclusion types A, B, C and D. The details of the standard are found in the ASTM Annual Book of Standards, Volume 03.01
What chemical composition and mechanical properties for material SA 234WPB?
SA 234WPB is the code of a carbon steel; see the ASTM or ASME specifications.
What is the saybolt color test?
It is the ASTM method D156 that used for the colour measurement of petroleum products.
What is nuclear-uranium and plutonium?
If you think to nuclear grade: uranium and plutonium very pure, the maximal values for impurities being limited by specifications as ASTM in USA, etc.
Specification of transformer oil of 33kv grade?
There are different specifications. Is this new oil or used oil? What type of oil is it? There are at least 3 classes of insulating liquids. I will assume that this is for new Mineral Oil such as Diala-A. Here are the minimum requirements from NETA ATS 2007: Dielectric Breakdown (ASTM D877) = 30 kv Interfacial Tension (ASTM D971) = 38 minimum Neutralization Number (ASTM D974) = 0.015 maximum Water Content (ASTM D1533) = 20 ppm maximum Power Factor @ 25C (ASTM D924) = 0.05% maximum Power Factor @ 100C (ASTM D924) = 0.40% maximum Color (ASTM D1500) = 1.0 Again if it is a different class of insulating fluid there will be additional and/or different limits.
What are the physical properties of crude oil?
Some of the most important physical properties of crude oil include: oAPI oAPI = (141.5/SG 15oF) - 131.5 The purpose of this equation was to extend the range of the specific gravity scale. Crude oil SG changes, although small, may be important. Crude Oils oAPI = 10 - 50 Higher oAPI, more paraffinic crude, higher yields of gasoline. Lower oAPI, more aromatic crude, lower yields of gasoline. Viscosity Resistance to flow, usually measured @ 100oF in centistokes (kinimatic viscosity) Pour Point Measured by ASTM D-97 - temperature at which oil ceases to flow. Diesel may contain waxes, smaller than candle wax, which could solidify in cold weather. Flash Point Temperature above which the oil will spontaneously combust. Fractions in vacuum tower are the least combustible. They are the heaviest. Vapor Pressure Measured by ASTM D-323. Also know as Reid vapor pressure (RVP). True vapor pressure is usually 5-9% > RVP Carbon Residue The solid residue (%wt) remaining after heating to coking temperatures (700-800oC) ASTM D-524 Ramsbottom Carbon ASTM D-189 Conradson Carbon CCR incr. then Asphaltene incr. Salt Content Measured by ASTM - 3230 (lb NaCl/1000 bbl) Desalting is necessary because NaCl content > 10 lbs/1000 bbl leads to corrosion Metals Measured by EPA Method 3040 These include Ni, V, Ag, Hg, Na, and Ca. Metals can cause catalyst deactivation and corrosion. Sediment and Water Measured by ASTM D - 96 These inorganic particles can lead to operational problems. Acidity Measured by ASTM - 664 Sulfur Measured by ASTM D - 129, 1552, 2622 Sour crudes > 0.5 wt% and sweet crudes < 0.5 wt%. Today it is difficult to find crudes below 1% sulfur.
What ASTM coves the sampling of aggregates?
ASTM D75 is the ASTM that covers the sampling of aggregates.
Is astm a105 is equivalent to astm 304?
no
What is the difference between astm a105 and astm a105n?
ASTM A105 and ASTM A105N are both specifications for carbon steel forgings used in piping applications, but there are some differences. Here's a quick overview: **Chemical Composition:** **ASTM A105:** This specification covers flanges, fittings, valves, and similar parts for use in pressure Specifies standards for forged carbon steel piping parts, including: Ambient conditions and higher operating temperatures of the system. **ASTM A105N:** The suffix "N" indicates that these materials are normalized. Normalization is a heat treatment process that refines the grain size and improves the mechanical properties of the material. **Heat Treatment:** **ASTM A105:** The standard A105 material is typically supplied in the as-forged condition, and it may or may not undergo additional heat treatment processes. **ASTM A105N:** The "N" designation indicates that the material is normalized, implying that it has undergone a heat treatment process to improve its mechanical properties. **Mechanical Properties:** **ASTM A105:** The mechanical properties are specified without any mandatory heat treatment. **ASTM A105N:** The normalization process is intended to improve the mechanical properties of the material and provide better strength and impact resistance. **Applications and Applications:** Both A105 and A105N materials are widely used in forged carbon steel piping components for a variety of applications, including: B. High temperature and pressure applications in the oil, gas and petrochemical industries. It is important to note that specifications and requirements may vary depending on the specific version or revision of the ASTM standard. Always refer to the latest edition of the relevant ASTM standard for the most accurate and up-to-date information. If you are working on a specific project or application, we recommend referring to the project specifications or contacting a materials engineer to ensure that the correct material is selected for the intended use conditions. .
