1. High strength: Fluid pipe materials usually have high strength and corrosion resistance, and can withstand high pressure, high temperature, and the erosion of harmful substances.
2. Good sealing: The connection part of the fluid pipe is sealed under high pressure, which can effectively prevent liquid or gas leakage.
3. Wide range of use: Fluid pipes can be used for different liquid or gas transportation processes, such as oil, natural gas, clean water, and wastewater.
Water supply fluid pipes are commonly used in water supply and irrigation projects, and are necessary pipes for agricultural water conservancy projects, water source transportation, irrigation of farmland, water resource management, and engineering maintenance.
Generally, by selecting water sources and transportation methods reasonably, adopting modern irrigation methods, scientific management and maintenance of projects, agricultural production efficiency can be improved, rural economic development can be promoted, and people's living standards can be improved.
Fluid pipes are often used in natural gas engineering to meet the needs of local residents and industrial production for natural gas.
Natural gas pipelines will connect regions that supply natural gas and regions that demand natural gas, providing reliable natural gas supply, promoting economic development and convenient living.
Pipelines are an important means of transporting oil. Oil transport, one of the components of fossil energy transport. Including crude oil transport and refined oil products transport two parts.
As of 2018, the total length of oil and gas pipelines in the world exceeds 2.4 million km, of which more than 50% is in the United States and Russia. Welded pipe for oil transportation is an important pipe product for oil transportation.

At present, carbon steel pipes can be divided into several categories according to the forming process, namely ERW steel pipes, LSAW steel pipes, SSAW steel pipes, and seamless steel pipes. Seamless steel pipes are further divided into hot extruded seamless steel pipes and cold drawn seamless steel pipes.
The main steps of the production process for ERW steel pipes are: uncoiling, straightening, forming, high-frequency resistance welding, removing welds, water cooling, sizing, cutting, testing, and warehousing.
The main steps in the production process of LSAW steel pipes are: steel plate inspection - trimming - pre bending - forging and cold forming - pre welding - internal and external welding - sizing - chamfering - UT inspection - water pressure inspection - appearance inspection - spray marking storage
The main steps in the production process of SSAW steel pipes are: uncoiling, cutting, butt welding, straightening, spiral forming, double-sided submerged arc welding, cutting, ultrasonic testing, water pressure testing, appearance testing, spray marking and storage.

Reasons for Steel Pipe Rusting
Steel pipe rusting is a complex chemical process, which is mainly caused by the following factors:
1. Oxidation reaction
The main component of steel is iron (Fe), and oxidation reaction occurs when iron comes into contact with oxygen (O₂) in the air.
2. The role of moisture
Water is not only a catalyst for oxidation reaction, but also dissolves carbon dioxide in the air to form a weak acid solution, which further accelerates the corrosion of the metal surface.
3. Electrochemical corrosion
In the presence of moisture, micro-battery structures will form on the surface of steel.
4. Environmental factors
Humidity: In a high humidity environment, the moisture content in the air is higher, which increases the possibility of oxidation reaction.
Temperature: Increased temperature usually accelerates the rate of chemical reactions, including oxidation and corrosion processes.
Pollutants: Pollutants in the atmosphere such as sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) can combine with water to form acid rain, exacerbating the corrosion of steel.
Soil conditions: Buried steel pipes are easily affected by factors such as soil type, pH value, and water content. Some types of soil are highly corrosive.
5. Mechanical damage
If the surface of the steel pipe is scratched, hit or otherwise physically damaged, destroying the original protective layer (such as coating or galvanizing), the exposed metal part is more susceptible to corrosion.
6. Influence of internal medium
For steel pipes that transport fluids, the nature of the internal medium will also affect its corrosion. For example, transporting acid and alkali solutions, seawater or liquids containing dissolved oxygen will accelerate the corrosion of the inner wall of the pipe.
