Overview
Stainless steel pipe is an economic cross-section steel, is an
important product in the steel industry, 304 stainless steel pipe
is widely used in petroleum, chemical, medical, food, light
industry, mechanical instrumentation and other industrial
transportation pipes and mechanical structural components. There
are many kinds of stainless steel pipes, different uses, different
technical requirements, and different production methods. There are
several classification methods for stainless steel pipes, and when
roughly distinguished, they are generally classified according to
alloy composition or metallographic organization. According to the
composition, it is divided into Cr series and CR-Ni series. Because
of the different metallographic structure, the chromium (Cr) series
is divided into Martensite series and ferrite series: while the
chromium nickel (Cr-Ni) series is divided into austenitic system
series and austenite/ferrite series.

Specification
ASTMA213 A213M-11a: Standard Speciicaton for Seamless Feritic and
Austentic Alloy -Steel Boiler Superheater,
and Heat-Exchanger Tubes
Advantage
1.Good anti-corrosion performance, effective prevention of a
pollution, in line with the national water quality standards.
2. High strength, strong extrusion resistance, resistance to common
shock, greatly reducing the possibility of leakage caused by
external impact of water pipes.It avoids the destruction of water
resources due to seepage
3.Good stability, at -20° C - 350° C
4. The pipe wall is smooth, uniform, no scaling, the path is
guaranteed, and the energy consumption is low.
5. Using traditional process connection, safe, reliable, flexible
and convenient.
6.Cost-effective
