Heavy Thickness SCH80S SCH160S Stainless Steel Inconel 625 Pipes
Alloy 625 pipe is a pipe made from thenickel-chromium-molybdenum
alloy625
Inconel 625 is a popular nickel-based superalloy primarilyused in
high-temperature and highly corrosive environments.
The alloy is known for its excellent strength, durability,
andresistance to corrosion
Alloy 625 pipe is often used in high-temperature and high-pressure
applications, such as in power generation plants and oil and gas
production facilities.It is resistant to corrosion by a wide range
of chemicals, including chlorine and sulfuric acid. Additionally,
it is also resistant to oxidation and
carburization at high temperatures.

Material Grades:
Stainless steel is the abbreviation for stainless and acid resistant steel. Steel that is resistant to weak corrosive media such as air, steam, water, or has rust resistance is called stainless steel; And the steel grade that is resistant to chemical corrosion media (such as acid, alkali, salt, etc.) corrosion is called acid resistant steel.
The most common used material is SS304/304L, SS316/316L, DUPLEX SAF2507, SAF2205, Detail’s specification of the material as below.

FAQ/ Customer Question and Answers
Q: What is difference between tubes and pipes?
A: Tubes and pipes are difficult to identify occasionally and some people use the name of tube and pipe interchangeably. However, there are significant differences between tubes and pipes. Tubes are measured in outer diameter and wall thickness. The tube is produced with close tolerance range and requires precise outer diameter and wall thickness to identify its working pressure.
Q: What is Difference Between Stainless Steel Pipes Seamless and Welded?
A: 1) Strength: The main difference between seamless and welded pipes is in their strength. Seamless pipes are stronger because they do not have any welded seams. Welded pipes are weaker because the welds can act as weak points that could break under high pressure.
2)Cost: Seamless stainless-steel pipes are more expensive than welded ones because they require more time and effort. Welded pipes are less expensive because they can be made quickly and with less precision.
3) Applications: Seamless stainless-steel pipes are typically used in high-pressure applications, such as hydraulic systems, while welded pipes are used in low-pressure applications, such as water piping.
