Austenitic stainless steels

SA213-T304:- The SA 213 Tp 304 Material consists of 18% chromium and carbon, manganese, phosphorus, sulfur, silicon and nickel in the composition.

SA213 TP304 is a series of pipes with minimum wall thickness. We offer SA 213 TP 304 pipes in different types, shapes and sizes. SA213 TP 304 material consists of 18% chromium and carbon, manganese, phosphorus, sulfur, silicon and nickel. There are also trace additions of molybdenum, nitrogen, niobium and titanium. The density of SA 213 TP 304 is lower than that of ordinary 304 material. It's 7.8 grams per cubic centimeter. We offer ASTM A213 TP 304 for high temperature service. The absolute roughness of our 304 stainless steel pipe fittings is small, which means that they can be used in high-precision equipment and applications.

Two sets of allowable stresses for austenitic stainless steel are proposed in ASME Boiler and pressure vessel code. The reason for this is that their yield strength is relatively low. Higher allowable stress values are determined at temperature, where use is limited by short-time tensile properties.

The higher stress is more than 62-1 / 2%, but not more than 90% of the yield strength. Under these stresses, a small amount of plastic deformation can be expected. These higher stress values are usually used for superheater and reheater tubes. The boiler specification lists the maximum allowable stresses at different temperatures, depending on each austenitic stainless steel grade. This 18 Cr, 8 Ni grade change includes 304L, 304ln, 304H and 304n. Each provides excellent corrosion resistance and oxidation resistance, as well as high strength. High strength is maintained in low carbon grades by controlling nitrogen content. T304 has high carbon content and minimum solution annealing temperature to ensure good long-term high-temperature strength. T304 is limited to 1650°F under oxidizing conditions. Section I of the ASME Boiler code lists allowable stresses up to 1500°F.

SA213-T316: - SA213 TP316 Tube is a material standard for heat exchanger tubes that are made from 316 austenitic stainless steel.

Chromium nickel alloy also contains molybdenum, which makes it more resistant to corrosion and heat than 304 material. ASME SA213 TP316 is the second largest pipe material in the world after 304 material. ASTM A213 TP316 pipe is an austenitic stainless steel, but standard 213 covers both austenitic and ferritic steels.

Union Victory is a supplier of ASTM A213 grade TP316 products of different standards and sizes. Our 316 stainless steel tubes can be polished or electropolished with different finishes, such as 316 stainless steel tubes. We also provide pipes of different shapes, such as circular, rectangular or stainless steel 316 square pipes. Square and 316 stainless steel rectangular tubes are usually used in high-pressure applications to withstand the pressure stress when the direction changes. Stainless steel 316 seamless pipe is more accurate in size, so it is used in high-precision applications. Our 316 stainless steel exhaust pipe is of high quality and can withstand high temperature; It is used in exhaust pipes, heat exchangers and super heaters. 316 stainless steel thick walled tubes are used in high pressure applications such as hydraulic systems. Our SS 316 welded pipe is easy to weld. We offer 316 stainless steel welded pipes of different sizes and schedules at a reasonable price. Please contact us for further details and prices.

SA213-TP321 & 347- SA213 TP321 is a specification of heat exchanger tubes that are made from the 321 austenitic stainless steel.

SA213 TP321 is the specification for heat exchanger tubes made of 321 austenitic stainless steel. SA213 specifies tube products for heat exchangers of different material grades, including Ferritic and austenitic steels.

Union Victory is a supplier of all kinds of stainless steel pipes. The special feature of SA213 TP321 material is that its composition includes titanium, which reduces the density of ASME SA213 TP321 and makes it lightweight. T321 and 347 are variants of T304 with comparable minimum tensile properties. These two brands are stabilized by adding titanium and Columbium respectively, and appropriate heat treatment is carried out at the same time. In order to ensure good long-term strength at high temperature, t321h and 347h - like 304H - have been developed with higher carbon content and specified minimum solution annealing temperature. Of all stainless steels, t309 (25 chromium, 13 nickel) and T310 (25 chromium, 20 nickel) provide the greatest oxidation and corrosion resistance. They also provide good high temperature performance. However, because these steels contain ferrite, they are more susceptible to corrosion σ Phase effect.

Application

For the low and medium pressure boiler and steam header pipes; for the high-pressure boiler and steam pipes, and the petrochemical industry pipes. Boiler tube is a metal tube located inside the boiler, which is used to heat water to produce steam. There are two main types of tubular boilers: water tube boilers and fire tube boilers. In a water tube boiler, water circulates in the tube and the hot gas generated by the furnace is heated outside. The boiler tube is installed in the boiler to heat water to produce steam. The boiler is a closed pressure vessel, which is designed in many types. Water tube boiler and fire tube boiler are the main types.
 

Fire tube boiler

A fire tube boiler is a type of boiler in which hot gas passes from the fire through one or more pipes that pass through a sealed water container. The heat of the gas is transferred through the pipe wall through heat conduction, heating water and finally generating steam. Fire tube boiler is the third of the four types of boilers in history: low-pressure water tank or "haystack" boiler, flue boiler with one or two large flue, fire tube boiler and high-pressure boiler with many small tubes

 

Water tube boiler

Water tube boiler is a type of boiler in which water circulates in tubes heated by fire. The fuel is burned in the furnace to produce hot gas and heat the water in the steam generation pipe. In smaller boilers, additional power generation tubes are separated in the furnace, while larger utility boilers rely on water injection tubes that form the furnace wall to produce steam. High pressure water tube boiler. Then the hot water rises into the steam drum. Here, the saturated steam is drawn from the top of the drum.
