The Benefits and Applications of Alloy Steel Pipes

​The main applications of alloy steel pipes is power station, nuclear power plant, high pressure boiler, high temperature superheater and re-heater coil etc. of high temperature pipeline and equipments.


The advantages of alloy steel pipes: 100% recycled, it is suitable for the national strategy of environmental protection, energy-saving and resource-saving. Therefore, the national policy encourages the expansion of the high pressure alloy steel pipe applications. At present, the proportion of the total alloy steel tube is half of the developed countries. The applications of alloy steel pipe provide a broad space for the industry development. According to the research of the China association of special steel alloy pipe expert group, our country’s high pressure alloy steel pipe material demand grows by an average of up to 10-12%.

How do I choose which alloy steel to use? Selecting the right alloy  for a specific application is vitally important in order to achieve a sustainable solution, while cost aspects must also be taken into consideration. There are several stages when material selection needs to be made: new applications and equipment, new processes and process changes, exchange of material due to poor performance, exchange of existing material to minimize cost

To make the right material selection it is important to get a full picture of the service conditions the steel will face. The first aspects to consider could be material related, for example: corrosion resistance, mechanical strength, fabric ability, physical properties, surface aspects

The Classification of Line Pipe

​Line pipe is manufactured from high-strength carbon steel, and is made to strict engineering and metallurgical specifications developed by the American Petroleum Institute (API). Here we will introduce the classification of line pipe.



Pipe mills produce two types of line pipe: seamless and welded. Seamless pipe is formed from a cylindrical bar of steel that is heated to a very high temperature and then is pierced with a probe to create the hole through the cylinder.  Rollers size the cylinder to produce the proper diameter and wall thickness. This technique is used to make small diameter pipe, from 0.5 inches to 24 inches in diameter.

Most pipe produced for interstate natural gas pipelines is the welded variety, because interstate systems require larger diameter pipe.  Pipe mills manufacture line pipe by forming a steel plate or coil into a cylindrical shape, and closing the seam using a welding process.  The mill evaluates the quality of the weld seam using ultrasonic and/or radiological inspection methods and pressure tests each joint of pipe to levels significantly higher than the eventual operating pressure of the pipeline.  

The pipe is further tested to ensure that it meets all requirements of steel chemistry, strength and toughness, and dimensional characteristics.  Mills that produce line pipe to API specifications meet the most stringent criteria for steel making and pipe production technologies to ensure safe, reliable pipeline service.  The gas pipeline industry maintains the manufacturing and test records of the pipe for the life of the pipeline.
