Boilers play an important role in various types of plants for the power and chemical industry. With the progress of these industries, modern boilers have become larger in size and the temperature, as well as the pressure, has increased. Therefore,…
Large diameter alloy steel pipes are those with an outer diameter exceeding 100 mm, wall thickness greater than 0.2, and the outer diameter of a pipe, and Large diameter alloy steel pipes are pierced with steel ingots or solid pipes, and then hot-rolled, cold-rolled, or cold dialed.
The alloying elements in ASTM A335 P91 Alloy steel Seamless Pipes tend to make either compounds or carbides or solid solutions.
ASTM A335 P11 steel is a ferritic alloy steel. This material has been in use successfully in power plant service.
ASTM A335 P9 Alloy steel pipe apply to petroleum, chemical industry, electric power, boiler, high temperature resistant, low temperature resistant, corrosion resistant.
16Mn is a kind of high strength low alloy structural steel, the carbon content of 0.12% -0.20% to join main alloying elements manganese, silicon, vanadium, niobium, and titanium.
GB5310 15CrMoG high pressure boiler tube with high lasting strength, high oxidation and corrosion resistance, good organizational stability, widely used in electrical equipment.
JIS G3458 Standard is made for heat resistant alloy steel pipes that are used for high temperature conveying fluid pipes for heaters and boiler tubes.
Piping Elbow and Piping bend are not the same, even though sometimes these two terms are interchangeably used.
During steel manufacturing, oxygen is forcibly injected into it to ledel. The oxygen combines with excess carbon and is released as a gas. Excess oxygen is, however, unavoidably left in the molten steel. This results in the formation of oxide…
