The application and uses of carbon steel pipe

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.

Carbon steel specification, Standard and identification

Carbon steel pipe tubing is used to transport fluids and gases in a variety of pneumatic, hydraulic, and process applications.

Carbon steel pipe cooling method varies with the material. For most kinds of steel use natural cooling to meet the requirements.

Carbon steel pipe is the most commonly and widely used in the gas project field.
The large diameter coated steel pipes are widely used in tap water, natural gas, petroleum, chemical, pharmaceutical, telecommunications, electricity, large diameter steel marine engineering field generally less than the outer diameter of the tubes 89 are collectively referred to as small-diameter steel pipe.

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.

Carbon steel pipe anti-rust oil: it is with a high corrosion resistance and adhesion,which does not contain harmful substances such as formaldehyde, benzene, heavy metals, environmental protection and the operator's physical and mental health.

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).

Improving the performance of the steel is two ways, First, adjusting the chemical composition of the steel alloying; the other is the heat treatment, heat treatment and shaping deformation combination of approaches. In the field of modern industrial technology, heat treatment to improve the performance of the steel still occupy a dominant position.

Advantages of carbon steel: smelting process is relatively simple, low cost, good pressure processing performance, good cutting performance and good mechanical properties.

Inner diameter of seamless steel pipe is more than 6.0mm and wall thickness is less than 13mm annealed seamless steel pipe material, which can be used W-B75 Webster Hardness test with very fast, easy, suitable for rapid non-destructive of the seamless steel pipe material qualified inspection.

Low carbon steel is a type of metal that has an alloying element made up of a relatively low amount of carbon. Typically, it has a carbon content that ranges between 0.05% and 0.30% and a manganese content that falls between 0.40 and 1.5%. Low carbon steel is one of the most common types of steel used for general purposes, in part because it is often less expensive than other types of steel.

Carbon steel pipe rusting

Carbon steel pipe anti-rust oil: it is with a high corrosion resistance and adhesion,which does not contain harmful substances such as formaldehyde, benzene, heavy metals, environmental protection and the operator's physical and mental health.

Brinell hardness (HB) with a certain diameter of the steel balls or tungsten carbide balls, pressed into the pattern surface of a predetermined test force (F), after the predetermined hold time after drop test force, the diameter of the measurement sample surface indentation (L).

Steel is an alloy that mostly contains iron. But its properties can be changed to suit specific requirements by adding certain other elements.

Encountered hole problems are very common in the welding process, welding materials drying, corrosion of the base metal and welding consumables, welding process is not stable enough oil and impurities and to protect the poor will be varying degrees of blowholes.

The strip is into the welded pipe unit and by the multi-channel roll rolling, gradually rolled strip steel, formed with an opening gap round tube, adjust the amount of reduction squeeze rollers, so that the weld gap control for carbon steel pipe in 1 - 3mm, and to weld ends flush. If the gap is too large and will result in reduced proximity effect, eddy current lack of heat, poor weld joint between grain yield incomplete fusion or cracking.

Delivery standard length of carbon steel pipe, also known as user requirements length or the length of the contract, there are four provisions in the existing standards

Carbon steel internal defects is generated in the carbon steel smelting defect smelting and casting process, such as segregation, non-metallic inclusions, porosity, shrinkage and cracks.

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.

Carbon steel defect is caused by the equipment, processes and operations in carbon steel smelting and rolling (forging) process, including scarring, cracks, residual shrinkage, layered, white point, segregation, non-metallic inclusions, such as osteoporosis and banded.

For S235 steel , S means structural . 235 mean it's yield strength should be more than 235 MPa. The steel grades S235 may be supplied in qualities JR, JR(G2),J0,J2, J2G3,J2G4.

S235 grade steel is a readily weldable low carbon manganese steel with good impact resistance (including in sub-zero temperatures).

This material is commonly supplied in the untreated or normalised condition and is available in several variations (denoted by additional letters and/or digits), which offer slight modifications of chemical composition and mechanical properties.

Machinability of this material is similar to that of mild steel.

  • JR means impact test at 20 degree.
  • J0 means impact test at 0 degree
  • J2 means impact test at -20 degree.

Delivery condition of S235 steel has :

Normalizing rolling (+N) : rolling process in which the final deformation is carried out in a certain temperature range leading to a material condition equivalent to that obtained after normalizing so that the specified values of the mechanical properties are retained even after normalizing.

as-rolled(+AR): delivery condition without any special rolling and/or heat treatment condition.

thermomechanical rolling: rolling process in which the final deformation is carried out in a certain temperature range leading to a material condition with certain properties which cannot be achieved or repeated by heat treatment alone.

Steel pipe world standards

Pipe manufacturing refers to how the individual pieces of pipe are made in a pipe mill; it does not refer to how the pieces are connected in the field to form a continuous pipeline. Each piece of pipe produced by a pipe mill is called a joint or a length (regardless of its measured length). In some cases, pipe is shipped to the pipeline construction site as “double joints”, where two pieces of pipe are pre-welded together to save time. Most of the pipe used for oil and gas pipelines is seamless or longitudinally welded, although spirally welded pipe is common for larger diameters. 1.
