What is the G48 corrosion test?
The G48 corrosion test is a standardized test method used to evaluate the resistance of austenitic stainless steels to intergranular corrosion.
Intergranular corrosion occurs when the boundaries between grains in a metal are attacked by a corrosive environment, leading to a loss of mechanical strength and potential failure of the material. Austenitic stainless steels are particularly susceptible to this type of corrosion due to their high chromium and nickel content.
The G48 test involves immersing a sample of the stainless steel in a boiling solution of 6% copper sulfate and 16% sulfuric acid for a period of 24 hours. The test measures the degree of corrosion in the material, particularly at the grain boundaries.
After the test, the sample is examined for signs of corrosion and evaluated based on the amount of corrosion that has occurred. The test results are reported as the weight loss of the sample or as the depth of corrosion penetration.
The G48 test is commonly used in the oil and gas industry, as well as in other industries where austenitic stainless steels are used in corrosive environments. The test is an important tool for evaluating the corrosion resistance of materials and ensuring their suitability for specific applications.

How do you calculate the pressure rating of instrumentation tubing?
The pressure rating of instrumentation tubing depends on several factors, including the material, size, wall thickness, and temperature of the tubing. The pressure rating indicates the maximum allowable working pressure (MAWP) that the tubing can withstand under specific operating conditions.
To calculate the pressure rating of instrumentation tubing, the following formula can be used:
Pressure Rating = 2 x S x t / D
where: S = allowable stress of the tubing material at the operating temperature t = wall thickness of the tubing D = outside diameter of the tubing
The allowable stress of the tubing material can be found in industry standards such as ASME B31.3 or ASTM A269. It is typically provided in units of pounds per square inch (psi) or megapascals (MPa).
The wall thickness and outside diameter of the tubing can be measured or obtained from manufacturer specifications.
It is important to note that the calculated pressure rating is only valid under the specific operating conditions for which it was calculated, including the temperature and the medium being transported through the tubing. Any changes in operating conditions may require a recalculation of the pressure rating. Additionally, it is recommended to always follow industry standards and guidelines for the selection and installation of instrumentation tubing.
What does DFARS mean and why is it important?
DFARS stands for Defense Federal Acquisition Regulation Supplement. It is a set of regulations that governs how the U.S. Department of Defense (DoD) procures goods and services from contractors.
DFARS was created to supplement the Federal Acquisition Regulation (FAR), which is the primary set of rules governing federal procurement. DFARS contains additional requirements and clauses that are specific to DoD procurement, such as rules for sourcing materials, supply chain security, and cybersecurity.
DFARS is important because it helps to ensure that the DoD’s supply chain is secure and that goods and services are procured from reliable sources. It also helps to protect sensitive information and technology from being compromised by foreign entities or other threats. Contractors who do business with the DoD must comply with DFARS regulations to be eligible for DoD contracts.
In summary, DFARS is an important set of regulations that helps to ensure the security and reliability of the DoD’s supply chain and procurement processes. Contractors who want to do business with the DoD must comply with DFARS regulations to be eligible for DoD contracts.
