Typically, pipelines classify base on the method of their production, which is usually welded or seamless. Welded pipes are preferred when large diameter pipes are required, while they work smoothly on projects
requiring small to medium-sized pipes. Welded pipes are further divided into different types, each of which has its advantages. Because the pipeline are supplied in different types, a specific type of pipe must be defined for the project prepare. Explore the upvc pipes
Pipeline
This is where the pipeline class comes in. By definition, a pipeline class is a document that contains a definition of pipes and their associated components used in specific pressure or temperature conditions. This document, which is usually prepared by a technician as the plant operator, usually contains information such as material details, dimensional data, diagram, flange ratings, piping types, and valve types. Each pipe type define by its base material, corrosion requirements, temperature and pressure range and other special requirements.
A pipe class document usually has short codes as abbreviations to make the information as detailed as possible. Definitions of these codes are located at the beginning or end of the document. To facilitate the material needed for the civil engineer, the pipe type indicate by a line number.
In addition, a type of pipe is a detail of a pipeline that covers an entire part of a plant or building.
pipeline details
pipeline specifications
To be more specific, the piping specification provides definitions and guidance on the following:
Design – minimum requirements for thermal expansion, charging rates, etc. Purchasing – Here you will find a list of material requirements that go beyond permitted standards, such as heat treatment.
Production – includes instructions on how the materials should manufactured, welded and installed in the piping system. He also talks about painting and cleaning processes.
Engineer-Describes how designs prepare and how the plant is built.
The pipeline Specification document is not only used during construction. But is also useful for repairs and maintenance. Because the piping specification contains all the information about a specific part of the piping system, it is used as a necessary reference for any changes made to the system.
One thing to note about the piping specifications document is that it is made specifically for a part of a plant or building. This means that the information in one pipeline specification may not be available in another section, so it is important to be specific to the pipe specification section.
As with the pipe class, the pipe specifications also use short codes and numbers to provide the most detailed information possible. Understanding how to read the piping specifications is essential for optimal use of the document. In the industrial field, piping means a system of pipes and tubes used to transfer oils, gases or other liquids from one place or another. Pipeline systems, located mainly in processing plants, refineries and petrochemical complexes, transport raw materials through refining techniques and production stages.
A piping system is a combination of several components for performing specific tasks, such as distribution, mixing, extraction and control of gases and liquids. In addition to piping, the system may include, but is not limit to, materials such as pipeline, fittings, flanges, separators, check valves, and drip rings.
Types of steels and their use in the pipeline industry
As production processes evolve and became more complex. The options for steel buyers expand to meet the many unique needs of different industries. But not all types of iron are the same. Pipe professionals can become better buyers by exploring the types of steel available today and understanding why some steels are good pipes and others are not.
This review should help.
Carbon steel
Steel form by adding carbon to iron, which is relatively weak in itself. In modern industry, the most well-known addition of ferrous material is carbon. but all the lower elements are common. In fact, alloying elements also common in tubular products. Which still consider carbon steel.
According to the American Iron and Steel Institute (AISI), ferrous material refers to as carbon steel if the core composition. Set to not exceed 1.65 percent manganese, 0.60 percent silicon, and 0.60 percent copper, and if not. It has a certain minimum value for others. Mixing elements. Carbon steel pipes widely use in many industries due to their durability and ease of operation. Because it has relatively few alloying elements and a short concentration, carbon steel piping is relatively inexpensive. However, it is not suitable for operation at high temperatures or high pressure, because the lack of lifting elements reduces its resistance to related stressors.
Alloy steel
Their audience is alloy steels: steels that contain a number of mixed elements. Often lower elements make steels stronger and more resistant to impact or stress. While the most common alloying elements include nickel, chromium, molybdenum, manganese, silicon, and copper, many others use to make steel. Countless combinations of alloys and concentrations use in the industry, each combination design to achieve specific properties.
High-alloy steels
High-alloy steels prefer in the piping industry for use in extreme conditions, whether hot or cold or unfavorable. The combination of chemistry. And good heat treatment can provide a strong but tensile tube. That can beaten. The oil, gas, and power industries generally prefer the bottom pipe because of its rigidity.
Alloy elements also provide steel pipes with increased corrosion resistance. This also makes it a leading choice for chemical companies.
Stainless steel
The term is a bit incorrect. There is no single combination of steel and alloying elements that makes stainless steel what it is. However, stainless steel indicates that its products do not rust. Stainless steel alloys can include chromium, manganese, silicon, nickel, and molybdenum. These alloys work together to interact with oxygen in water and air and quickly form a thin but strong film on the steel surface that prevents further corrosion.
Stainless steel pipes
Of course, stainless steel pipes use in every industry where corrosion protection require. While the stainless steel pipe is a basic alloy pipe of another name. It is not suitable for heavy-duty operation. Unless it properly heat-treat to increase strength. And impact resistance. Due to its aesthetic appeal, stainless steel chose whenever the pipe is to be visible to the public or in a professional environment.
Used iron
Steel tools are the production of other types of steel products as equipment used in industry. It must be extremely strong, tough, tensile, and corrosion-resistant. They must also able to cut edges and maintain their shape at high temperatures. To achieve these qualities. These steels have a very high concentration of alloying elements. And precisely heat treat.
Superalloys
Tool steels, sometimes call superalloys, are not suitable for tubular products. First, the use of more alloys makes steel tools more expensive. Second, the number of alloying elements present in steel tools makes it difficult to shape tubular products. Finally, the pipes do not require cutting edges. It is cheaper and easier to use relatively mild. Low-alloy steels to form the pipe and then heat it to a specific hardness.
