Product Characteristics:
The four major pipelines of thermal power plants include:
1. Main steam pipeline (two high temperature and high pressure
steam pipelines between the superheater outlet header and the high
pressure main steam valve interface);
2. Hot reheat steam pipeline (two high temperature and high
pressure steam pipelines from the outlet header of the reheater to
the interface of the medium pressure main steam valve);
3. Cold and reheat steam pipeline (two high-temperature and
high-pressure steam pipelines between the exhaust port of the
high-pressure cylinder and the inlet header of the reheater);
4. High-pressure water supply pipeline (the high-pressure boiler
supply water pipeline between the outlet of the electric feedwater
pump and the inlet header of the economizer).
It can be used in ultra-supercritical units and above 600 degrees
Celsius. A335p92 alloy tube implements the standard astma335/a335m.
The main alloy composition is cr: 9%, mo: 1%. The main steam
pipeline and reheat steam pipeline sa-335p92 steel is in sa-335p91
On the basis of the four major pipelines of the power station, the
content of the mo element was appropriately reduced, and a certain
amount of w was added to increase the molybdenum equivalent
(mo+0.5w) of the material from 1% of p91 steel to about 1.5%. A
trace amount of boron and four high-temperature pipelines are also
added. After the above-mentioned alloying and improvement, compared
with other commonly used heat-resistant steels in the 9%cr series,
its high-temperature corrosion resistance and chemical properties
are similar, but the high-temperature strength and creep resistance
are similar. Variable performance has been improved. P92 material
is American steel grade astm a335 and p92 is a martensitic
heat-resistant steel. In recent years, it has been used more in
thermal power plants, mainly for main steam pipes and reheat steam
pipes. Executive standard: astma335/a335m astma213/213m The main
alloy composition is cr: 9%, mo: 1%, etc. a335p92 alloy pipe

pressure a335p91 elbow, high temperature and high pressure large
diameter thick wall a335p91 steel pipe, p91 elbow thermal power
water and steam pipelines are usually Divided into four major
pipelines: main steam pipeline, high temperature reheat steam
pipeline (hot section), low temperature reheat steam pipeline (cold
section) and high pressure water supply pipeline.
