Products Description
Astm A312 Tp316 316l 316ti Seamless Stainless Steel Pipe
Advantages of Tp316 316l 316ti Seamless Stainless Steel Pipe
- TP316, due to the addition of molybdenum, offers superior resistance to pitting, crevice, and chloride corrosion compared to TP304. For applications in moderately corrosive environments that do not require welding or high temperatures, TP316 may be a more economical option.
- TP316L minimizes the risk of intergranular corrosion during welding and offers resistance to more demanding corrosive media.
- TP316Ti, due to the addition of titanium, is suitable for high-temperature environments and offers enhanced high-temperature stability, making it ideal for offshore platforms and shipbuilding applications.
applications of Tp316 316l 316ti Seamless Stainless Steel Pipe
TP316, TP316L, and TP316Ti seamless stainless steel pipes are commonly used in applications requiring basic chloride corrosion protection but without the risk of extremely high temperatures or intergranular corrosion during welding, such as chemical raw material transportation and residential and commercial HVAC/water supply. Specific applications are as follows:
- TP316 seamless stainless steel pipe: Industrial piping systems, building curtain wall support structures
- TP316L seamless stainless steel pipe: Chemical reactors, desalination high-pressure piping, nuclear power cooling systems, pharmaceutical production equipment, ship condensers, etc.
- TP316Ti seamless stainless steel pipe: Boiler piping, heat exchangers, petroleum refining equipment, automotive exhaust ducts, etc.
