• The deoxidizing agent reacts with the oxygen and other impurities in the molten steel to form a slag, which is then removed from the surface of the steel.

• This process helps to prevent ga...read more

The number of tests conducted in the site lab varies depending on the project requirements and stage of construction.

• The number of tests conducted in the site lab depends on the type of construction project.

• Tests may include soil testing, concrete testing, asphalt testing, and material quality testing.

• The frequency of tests may increase during critical stages of construction.

• The number of tests conducted can be influenced by project specifications and regulatory requirements....read more

Pipe thickness calculation as per ASME b31.3 and well head piping.

• Pipe thickness calculation involves determining the required wall thickness to withstand the internal pressure and external loads.

• ASME B31.3 provides guidelines for process piping while wellhead piping requires additional considerations such as corrosion and erosion.

• Factors such as material properties, design temperature, and pressure rating are also taken into account.

• Various methods such as the Barlow's formu...read more

The type of electrode used in structure welding depends on the specific requirements of the project.

• Common types of electrodes used in structure welding include E6010, E7018, and E7014.

• E6010 electrodes are used for deep penetration and are often used in pipeline welding.

• E7018 electrodes are known for their high tensile strength and are commonly used in structural steel welding.

• E7014 electrodes are versatile and can be used for both vertical and overhead welding.

• The choice of ...read more

The velocity of steel varies depending on the type and conditions.

• The velocity of steel can range from 5000 to 6000 meters per second

• The velocity of steel can be affected by factors such as temperature and pressure

• The velocity of steel is important in industries such as construction and manufacturing

Tax deduction in RA BILL

• Tax deduction is applicable on certain items in a RA bill

• The deduction amount varies based on the item and tax laws

• Examples of items with tax deduction include TDS, GST, and service tax

The volume of a trapezoidal shape can be calculated using its height and the lengths of its parallel sides.

• The formula for calculating the volume of a trapezoidal shape is (1/2) x height x (length of parallel side 1 + length of parallel side 2)

• The height is the perpendicular distance between the parallel sides

• For example, if the trapezoidal shape has a height of 5 units, a length of parallel side 1 of 8 units, and a length of parallel side 2 of 12 units, the volume would be (...read more

Material handling products/equipment are designed to efficiently move, store, and control materials during the manufacturing process.

• Material handling products/equipment are designed to improve efficiency, productivity, and safety in a manufacturing or distribution facility.

• They can include conveyors, forklifts, pallet jacks, cranes, and automated guided vehicles.

• The working principle involves transporting, storing, and controlling materials using various mechanisms such as b...read more

An intermediate Geo material is a material that falls between two extremes in terms of its geotechnical properties.

• Intermediate Geo materials have properties that are neither purely cohesive nor purely granular.

• They may exhibit characteristics of both cohesive and granular materials.

• Examples include silty sands, sandy clays, and clayey gravels.

Lateral load test is a procedure to determine the strength and stability of a structure against horizontal forces.

• The test involves applying a horizontal force to the structure and measuring its response.

• The force is usually applied using hydraulic jacks or a reaction frame.

• The test is performed on a representative section of the structure, such as a column or a wall.

• The results of the test are used to verify the design assumptions and to calibrate the structural model.

• The la...read more

BBS calculation is a method used to determine the reinforcement required for a pile.

• BBS stands for Bar Bending Schedule.

• It involves calculating the length and number of steel bars required for the pile.

• Factors such as load capacity, soil type, and pile diameter are taken into consideration.

• The BBS is used to ensure the pile can withstand the required load and prevent failure.
