Types and Definitions of Steel Pipes

Steel pipes are hollow long strips of steel, which are widely used as pipelines for conveying fluids, such as oil, natural gas, water, coal gas, steam, etc. In addition, when bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, gun barrels, shells, etc.

Carbon Steel Square Tube

Square tubes are made of a variety of materials, including carbon steel, alloy steel, stainless steel, etc. Carbon steel is the most commonly used material. According to the carbon content, it can be divided into ordinary carbon structural steel and high-quality carbon structural steel. Low carbon steel is ordinary carbon structural steel, and the carbon content is generally between 0.05% and 0.25%. Square tubes can be divided into seamless square tubes and welded square tubes according to the production process. According to the cross-sectional shape, they can be divided into rectangular tubes and square tubes. The most obvious difference between carbon steel square tubes and traditional square tubes is that they are made of different materials. Carbon steel square tubes are of better quality than ordinary square tubes, and have strong corrosion resistance and friction resistance.

Types and Benefits of Piling Pipe

Piling pipes are a simple and easy to understand type of pile. Since they are made of steel, they can bear extremely heavy loads, and the right steel can make them almost unaffected by environmental conditions. Steel pile pipes play a decisive role in large construction sites such as ports, bridge construction, and pile foundations. Today, we will introduce the types and advantages of steel pile pipes in detail.

ASTM SA/A106 Seamless Carbon Steel Pipe

This specification covers carbon steel pipe for high temperature service. These pipes are suitable for welding, bending, flanging, and similar forming operations. Mechanical tests on the specimens shall include tensile, bending, flattening, hydrostatic, and nondestructive electrical tests. Specimens for bend tests shall consist of sections cut from the pipe. For flattening tests, the ends of the specimens shall be smooth and free of burrs unless performed on cut ends. All tests shall be conducted at room temperature. If any specimen develops a defect, it may be discarded and replaced with another specimen. Retesting shall be permitted if the specimen is scratched before testing. Retesting shall also be permitted if the specimen breaks at an inner or outer surface defect.

Carbon Steel Square Tubes VS Stainless Steel Square Tubes

Most of the materials we use now are composite materials, and there is almost no single element. For example, the steel we often use is an alloy composed of iron, carbon, silicon, manganese, phosphorus, sulfur and other elements. Everyone knows that iron is white or silvery white. What subverts people's cognition is that iron is relatively soft. Is it hard to imagine that iron is soft, so pure iron cannot be used. The steel-like body we often say, hard as iron, etc., are all gone. Therefore, the steel we use in daily life is an alloy, which utilizes some characteristics of other elements, such as the hardness of carbon. Today we are talking about carbon steel square tubes, which refers to the carbon content in steel. Carbon steel generally does not have any corrosion resistance. The hardness is greater than that of pure iron. Of course, carbon is also controlled to a certain extent. Because ordinary carbon steel square tubes are not rust-proof, stainless steel carbon steel square tubes have also been developed accordingly.

Difference between seamless black steel pipe and black iron pipe

Black steel pipe is made of ungalvanized steel. Its name comes from the dark iron oxide coating on its surface in a scaly shape. Because its surface is dyed dark by iron oxide during the manufacturing process, it is called black steel pipe. According to the production process, black steel pipe is divided into two main types: seamless pipe and welded pipe. ASTMA53/A53M is the standard specification for pipes, steel, black and hot-dip galvanized, welded and seamless.

ASTM A106 Grade B Pipe Specification

ASTM A106/ASME SA106 is a standard specification for seamless carbon steel pipe for high temperature service. It includes three grades: A, B and C, of which Grade B is the most commonly used. This type of pipe is used in various industries, including piping systems for oil and gas, water and mineral slurry transportation. It is also used in boiler systems and for building and structural purposes.

API Coupling and Threads for Casing and Tubing

A casing coupling is a short pipe used to connect two threaded casings. API couplings are also called OCTG couplings and nipples. The internal threads are machined to match the external threads of the casing long joints. The two joints of the casing are screwed into the ends of the coupling, which is usually made of the same grade of steel as the casing to ensure its strength. All casing couplings are manufactured in accordance with the latest version of the API 5CT specification and are usually made seamlessly, with the same material grade as the pipe body (such as API 5CT K55/J55, N80, L80, P110, etc.). The PSL grade of the coupling is consistent with that of the casing, or a higher grade product is provided according to demand. Unless there are special requirements, the same heat treatment process is usually used.

Differences between Annealing, Normalizing, Tempering and Quenching of Seamless Steel Pipes

Many friends do not understand the meaning of annealing, normalizing, tempering and quenching of seamless steel pipes. If these concepts are confused, it is easy to cause irreversible consequences during the production and use of materials. Therefore, it is particularly important to correctly understand the various meanings of heat treatment of seamless steel pipes. Let's take a look at the heat treatment process of seamless steel pipes

Characteristics and uses of low carbon steel pipe

As the name implies, low carbon steel pipe is a steel pipe with a low carbon content. Generally speaking, there is a difference between low carbon steel pipe and seamless carbon steel pipe. Low carbon steel pipe refers to a steel pipe with a carbon content of less than 0.3%, and seamless low carbon steel pipe is one of them. Low carbon steel pipes include general steel pipes, medium and low pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes and other steel pipes, as well as carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless steel thin-walled steel pipes, special-shaped steel pipes, etc.

Steel Pipe Dimensions & Sizes Chart (Schedule 40, 80 Pipe) Means

Steel pipes are fabricated in different schedules for different applications. Where the schedule means the measurement of the pipes, specifically the thickness of the wall. As the schedule number increases the thickness of the wall increases where the diameter can still remain constant or varying as per customers requirements. As the internal diameter plays a vital role in providing fine workability as it bears all the pressure and heat. These pipes have various industrial applications and have a huge commercial demand. Unlike Schedule 10 pipes and Schedule 40 pipes, the Schedule 80 pipes have higher strength comparatively and it is designed for high temperature application and have a high pressure bearing capacity.
