The complex chemical and physical properties of the various grades of carbon steel pipe allow for a broad range of service usage. American piping products has the right grade, size and price to meet your requirements, including A/SA-106 Grade B/C and API 5L X- 42 thru X -70. A/SA-106 Grades B & C are utilized for services ranging from structural supports to steam drum headers with temperature ranges up to 800°F, while API 5L X Grades 42 thru 70 are utilized for the water and petroleum industry to transport liquids or as platforms on off-shore rigs.
The Application And Uses
Carbon steel has good properties in hardness and strength, and it is less expensive than other steels.
The properties of carbon steel are high hardness, strength, wear resistance and anti-corrosion. The percentage of carbon in the steel affects the hardness, strength of elasticity and ductility of carbon steel.
Carbon steel seamless pipes are extensively applied in the nuclear device, gas conveyance, petrochemical, shipbuilding and boiler industries, with characteristics of high corrosion resistance combined with suitable mechanical properties.
Related carbon steel pipes
Carbon steel is an alloy with carbon and iron, with carbon content up to 2.1% by weight. The increase in the carbon percentage will raise steel’s hardness and strength, but it will be less ductile.
Mechanical properties
Carbon steel tube mechanical properties is generated in the carbon steel smelting defect smelting and casting process, such as segregation, non-metallic inclusions, porosity, shrinkage and cracks.
Density
Density is calculated by dividing the mass by the volume. The density of carbon steel is approximately 7.85 g/cm3 (0.284 lb/in3).
Steel is much denser than water but shaped appropriately, the density may be reduced (by adding air spaces), creating a steel ship that floats. Likewise a life jacket reduces the overall density of the person wearing it, enabling him to float much easier.
There is not one value for density that is the same for all types of steel. Different steels are different alloys, although I wouldn’t have thought the values would vary greatly since all are largely steel.
China technical requirements for seamless steel pipes for high pressure gas cylinders
The steel material for the high-pressure gas cylinder is a kind of dead steel without aging, which is usually melted by an alkaline open hearth furnace, an electric furnace and an oxygen blowing alkaline converter, and some kinds of steel must be melted by electroslag or vacuum.
What is a seamless steel pipe?
Seamless steel pipes are perforated from whole round steel, and steel pipes without welds on the surface are called seamless steel pipes.
What is the effect of alloying elements in steel pipes?
Alloy steel is a steel that has small amounts of one or more elements (in addition to carbon) such as manganese, silicon, nickel, copper, chromium and molybdenum in addition.
What are the materials of thick-walled alloy tubes?
The performance of alloy pipe is much higher than that of general seamless steel pipe, because this steel pipe contains more Cr, and its high temperature resistance, low temperature resistance, corrosion resistance is not comparable to other seamless steel pipes, so alloy pipe is widely used in petroleum, chemical, electric power, boiler and other industries….
Process flow of seamless pipe
In both the manufacturing methods, raw steel is first cast into a more workable starting form (hot billet or flat strip). It is then made into a pipe by stretching the hot steel billet out into a seamless pipe or forcing the edges of flat steel strip together and sealing them with a weld.
What are the processing characteristics of thick-walled seamless carbon steel pipes?
Dimensional stability. For high-precision seamless carbon steel pipes, high precision is required, so dimensional stability needs to be maintained. Due to straightening in air, the cooling rate is slow, so it has a stabilizing effect on austenite. It will increase the amount of retained austenite in the structure, so cold treatment is required. Reduce quenching…
Cold-rolled seamless pipes should be pickled in the production process
As we all know, the cold-rolled seamless pipe has a bright surface and is not easy to rust.
Surface treatment of seamless carbon steel pipe
Mainly use steel brush and other tools to polish the steel surface, can remove loose or warped oxide skin, rust, welding slag, etc.
Development trend of seamless steel pipe cold rolling mill
Seamless steel pipe series products with its corrosion resistance, high temperature resistance, high pressure resistance and other advantages, widely used in petrochemical industry, ocean engineering, aerospace and other fields.
Performance index of seamless carbon steel pipe
The mechanical properties of seamless carbon steel pipe are important indicators to ensure the performance (mechanical properties) of steel, and it depends on the chemical composition of the steel and the heat treatment system.
High quality mechanical properties of seamless carbon steel pipes
If seamless carbon steel pipe is used for carburizing, hard and brittle martensite will appear in the core after quenching, and the advantages of carburizing will be lost.
Heat treatment process of seamless carbon steel pipe
There are many varieties of seamless steel pipes, and the steel grades (species) used are not the same.
