TMT bars are manufactured through a process involving steel melting, casting, and controlled cooling to enhance strength and ductility.

• 1. Steel Melting: Scrap steel is melted in an electric arc furnace (EAF) or induction furnace.

• 2. Continuous Casting: The molten steel is poured into a continuous casting machine to form billets.

• 3. Rolling: The billets are heated and passed through a series of rollers to shape them into ...read more

Steel melts at 1370-1510°C, while iron melts at approximately 1538°C, varying with composition and alloying elements.

• Steel is an alloy primarily made of iron and carbon.

• The melting point of steel can vary based on its carbon content and other alloying elements.

• For example, low-carbon steel melts around 1425-1540°C.

• Iron, being a pure element, has a consistent melting point of about 1538°C.

To calculate the weight of a 6mtrs pipe with dimensions 38x38x2.0

• Calculate the volume of the pipe using the formula: length x width x thickness

• Convert the volume to weight using the density of the material

• Weight = Volume x Density

1.5 inch pipe OD is equal to 1.900 inches.

• 1.5 inch pipe OD is equivalent to 1.900 inches in diameter.

• OD stands for outer diameter in pipe measurements.

• OD is an important parameter in pipe manufacturing and sizing.

6310 bearing has a larger bore diameter than 6210 bearing.

• 6310 bearing has a bore diameter of 50mm, while 6210 bearing has a bore diameter of 50mm.

• 6310 bearing has a larger outer diameter and width compared to 6210 bearing.

• 6310 bearing is typically used in heavier duty applications compared to 6210 bearing.

ISI 4923 is a standard for steel tubes used in structural purposes, while ISI 1239 is a standard for steel tubes used in water, gas, and sewage purposes.

• It is commonly used in the manufacturing of pipes for various industries such as oil and gas, construction, and automotive.

• ERW pipes are known for their high strength, durability, and precision in dimensions.

• The process invo...read more

HR pipes are hot rolled while GI pipes are galvanized iron pipes.

• HR pipes are made by rolling steel at high temperatures, resulting in a rough surface finish.

• GI pipes are coated with a layer of zinc to prevent corrosion and rust.

• HR pipes are typically used for structural applications, while GI pipes are commonly used for water supply and drainage.

• HR pipes are cheaper than GI pipes due to the additional galvanization pr...read more

Rolling is a metal forming process in which a metal stock is passed through one or more pairs of rolls to reduce thickness and to make the thickness uniform.

• Rolling is a metal forming process used to shape and reduce the thickness of metal stock.

• It involves passing the metal through pairs of rolls that exert pressure to deform the metal.

• Rolling can be hot rolling (done above the recrystallization temperature of the met...read more

Tensile test procedure involves applying a controlled tension force to a material sample to determine its mechanical properties.
