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.

• ISI 4923 is for structural purposes, while ISI 1239 is for water, gas, and sewage purposes

• ISI 4923 specifies requirements for hot finished seamless and electric resistance welded steel tubes

• ISI 1239 covers galvanized steel pipes used for water, gas, and sewage purposes

ERW stands for Electric Resistance Welding, a method used in steel plants to manufacture pipes.

• ERW is a type of welding process where high-frequency electrical current is used to create a weld seam.

• 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.

• Prepare the test specimen according to standards such as ASTM or ISO.

• Secure the specimen in the testing machine grips.

• Apply a gradually increasing tensile force until the specimen fractures.

• Measure and record the force applied and the corresponding elongation of the specimen.

• Calculate the tens...read more
