Introduction
Seamless pipe has a cylindrical structure that is used to transport liquids, gases, solids or even energy. This cut is produced in specific thicknesses and standards and can be made of various materials such as steel, plastic, iron, brass, etc.
What is a seamless pipe?
Seamless pipe is a type of steel pipe that is produced without any joints or seams. This type of pipe is produced by a process called cold drawing method. In this process, a piece of hot steel block is cut to the required size and then it is turned into a tube shape using special molds and high pressure.
How to make a seamless pipe
As we said before, seamless pipes are made of steel or aluminum, etc. The following methods can be used to make these pipes:
1. Casting:
This method involves melting metal and pouring it into special molds. Casting can be used to make seamless steel pipes.
2. Cold condensation:
Cold working is a processing process used in the production of seamless pipes. In this process, the pipes are deformed to their final shape and size by high pressure and mechanical strength. With cold compression, stronger, more resistant and more accurate materials are produced. This process causes tension and scratches in the pipe wall, which increases the durability and strength of the pipe. As a result, the tubes obtained from this process have high quality and accurate dimensions and are suitable for use in high temperature and pressure.
3. Extrusion method:
This method involves extruding (passing metals through a shaped hole) steel solids in the form of a tube. This method is usually used to make small and fine pipes.
By choosing one of the above methods, you can produce high-quality seamless pipes capable of transporting liquids and gases at high pressure.
Having the only 5-meter ring rolling machine in Iran, AzinForge has the ability to produce seamless pipes up to a height of 1600 mm. Also, this company has the ability to produce seamless pipes up to 10 meters long, with advanced devices and with the help of leading experts in science and technology.
Materials used in making seamless pipes
The raw material of seamless pipe is selected according to the type of application and different environmental conditions. Some of the materials used in making seamless pipes are:
1. Carbon steel: This type of steel (ASTM A53, ASTM A106, API 5L) is very suitable for the production of seamless pipes, because it has favorable mechanical properties and is flexible.
2. Alloy steel: Alloy materials such as chromium and molybdenum alloy steel are also used to produce seamless pipes, because these alloys give the pipe high mechanical properties and resistance to corrosion and heat. For example, ASTM A335 is for molybdenum cream alloy tubes, and ASTM A387 is for magnesium/chromium/molybdenum alloy sheets.
3. Stainless steel: This type of stainless steel (ASTM A312, ASTM A269, ASTM A789) is used to produce seamless pipes in industries that require corrosion or high temperature.
4. Aluminum: Aluminum (ASTM B241, ASTM B429) is also used to produce light and corrosion-resistant pipes.
5. Copper: This metal is also used to produce seamless pipes in certain industries.

Application of seamless pipe
Seamless pipes have very high physical and mechanical properties, which make them one of the best options for transporting liquids and gases in various industries. These pipes are generally used in oil and gas industries, chemical industries, automotive and construction industries.
The difference between a seamless pipe and a seamed pipe
As the name suggests, Seamless Pipe is without seams or welds and is produced through hot rolling and cold rolling. As the name suggests, the seamed pipe has a seam. Welding has been done on the surface of the seamed pipes.
Seamless pipes have many advantages over welded pipes. Some of its advantages are:
1- High resistance to pressure and heat
2- No penetration of liquids and gases
3- High flexibility
4- Long life
Conclusion
As a result, seamless pipes are an excellent choice for various industrial and refinery applications and are recognized as one of the most advanced and high-performance technologies in the industry. Also, due to the importance and widespread use of pipes in various industries, the design, production and proper maintenance of these structures is very important so that materials and energy can be transferred correctly and safely.
