Commonly fabricated materials and specifications are:
Alloy steel
Alloy steel is often subdivided into two groups: high alloy steels and low alloy steels. The difference between the two is defined somewhat arbitrarily. However, most agree that any steel that is alloyed with more than eight percent of its weight being other elements beside iron and carbon, is high alloy steel.
Stainless Steel
Stainless steel does not readily corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity, or poor circulation environments. It is also called corrosion-resistant steel or CRES when the alloy type and grade are not detailed, particularly in the aviation industry.

Carbon Steel
Carbon steel is steel where the main interstitial alloying constituent is carbon in the range of 0.12-2.0%.
Black steel
Black steel is a term given to steel pipe with a black oxide scale on the surface. This black oxide scale is formed when the pipe is forged and is typically sealed with a protective oil to prevent corrosion. Because of this oxide scale and protective film, black steel pipe requires little maintenance and is used for a wide variety of applications, including in water, steam, air and gas services. Black steel pipes are typically cut and threaded in the field.

What Is Abrasion Resistant Steel
Some abrasion is intentional, such as sanding, grinding, and blasting. However, unintentional abrasion can lead to component failure so it is important to use the proper materials to ensure that surface wear does not lead to unanticipated breakdown of structures or parts. While steel in general has excellent resistance to abrasion, not all steels are equal.
How Does It Work?
The chemical composition of abrasion resistant steel is one of the attributes that make it more immune to wear than other types of steel. There are several alloys that can be used increase the abrasion resistance. Carbon helps block dislocations, which increases the hardness and strength of a steel. The added carbon also allows the steel to form microstructures with increased hardness when heated and quenched. There are other elements that can be added to abrasion resistant steel to increase its hardness value too. Chromium and manganese are also added to abrasion resistant steels to help reduce the negative effects caused by wear.
Heat treatment is another factor that helps the steel resist abrasion. Abrasion resistant steel must have a microstructure that allows it to have a high hardness. This is accomplished, in part, by adding the proper alloying elements. However, this alone is not enough to ensure the proper microstructure is formed. The steel must also undergo a heating and a rapid quenching process to form microstructures such as martensite and bainite which gives the steel the required high hardness values. Care must be taken when welding or heating abrasion resistant steels. If they are heated to a high enough temperature, it may have an annealing effect on the steel, causing it to lose some of its hardness and, therefore, its abrasion resistance.
What Types of Abrasion resistant pipes Are Available?
There are several different abrasion resistant steel grades. Each grade is typically made to a specific Brinell hardness value, as opposed to other steels that are made with tensile strength and toughness in mind. This is because hardness is one of the most important factors when trying to increase abrasion resistance.
Self-propagating high temperature synthesis (SHS) is used to describe a process in which the initial reagents (usually powders), when ignited, spontaneously transform into products due to the exothermitic heat of reaction.
A well-known example of SHS reaction is the thermite reaction given below:
Fe2O3 + Al → 2Fe + Al2O3
This reaction generates temperatures above the melting point of alumina and is used in the thermit welding process for joining railway lines.
Several other terminologies - such as combustion synthesis, gasless combustion or self-propagating exothermic reaction - are used to describe the process.
The types of material that can be formed using this process include metal borides, silicides, carbides, nitrides, sulphides, aluminides and oxides.

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.
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.

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.
