Large OD Seamless Stainless Pipe
Seamless pipes are thought to be able to withstand higher pressure, higher temperatures, higher mechanical stress and a corrosive atmosphere. It can be found in a wide range of applications such as in oil and gas, refinery, petrochemical, chemical, fertilizer, power, automotive, bearing, mechanical and structural.
Stainless steel is one of the most popular and versatile materials. Seamless stainless steel pipe is used in applications where high temperature strength and superior corrosion resistance are critical. Further, stainless steel is easy to clean and doesn’t tarnish.
Stainless steel is an iron alloy that contains a minimum of 10.5% chromium. Alloying elements such as nickel, molybdenum, titanium, carbon, nitrogen, and copper can boost the strength, formability, and other properties of stainless steel. Different alloys offer different levels of corrosion resistance.

Alloying elements such as nickel, molybdenum, titanium, carbon, nitrogen, and copper can boost the strength, formability, and other properties of stainless steel. Different alloys offer different levels of corrosion resistance.
Stainless steel alloys offer greater cryogenic toughness, a higher work hardening rate, increased strength and hardness, greater ductility, and a more attractive appearance compared to carbon steel.
It is the resistance of air, steam, water and other weak corrosive media and acid, alkali, salt and other chemical etching medium corrosion of steel pipes. Also known as acid – resistant stainless steel. It will be more and more engineering use and become increasingly popular, and prospects.

Manufacturing Process of Stainless Steel Pipe
Seamless stainless steel pipe is made from solid stainless steel bar which is called billet. By using different processing techniques such as extruding, gun drilling or piercing, the steel bars are produced to be steel tubes.
- Firstly, the billets would be inspected exactly.
- Then put the billets into the heat to raise the temperature.
- The hot billets would then be pierced through the center with a mandrel. Through this procedure, the bar shape billet becomes hollow shape billet.
- The next step is rolling and stretching the hollow billet. The billet is precisely rolled and stretched until it meets all the specifications with length, diameter and wall thickness according to requirements.
