Stainless Steel 304L Pipe Fittings

stainless steel 304l pipe fittings

What are Stainless Steel 304L Pipe Fittings?

The Stainless Steel 304L material is the low carbon version of the Stainless Steel 304 material. The difference in carbon content affects their corrosion resisting properties. The Stainless Steel 304L Pipe Fittings possess high strength as they have a min tensile strength of 515MPa and yield strength of 205 MPa.
The operating temperature of the A403 WP304L Elbow can go as high as 870 degrees C. The UNS S30403 long radius and short radius elbow are quite strong, and thus, they can be found in high pressure applications. The low carbon content in the chemical composition of the DIN 1.4306 180° Return bends makes its welding operation smooth.

 

There is less chance of carbide precipitate formation while welding AISI 304L equal and reducing tee, and thus it avoids intergranular corrosion. It also reduces the occurrence of localized corrosion.

The SUS 304L End Cap is widely used in different industries to stop the piping connection. The 304L Stainless Steel Stub End can be found in various industries, including petroleum, marine, pharmaceutical, medical, and so on.

ASTM A403 WP304L Pipe Fittings manufacturing process


Manufacturing Process of ASTM A403 WP304L Pipe Fittings

ASTM A403 Gr WP304L Butt weld pipe fittings and SS 304L concentric reducer in Schedule 10/ 10S

The ASTM A403 WP304L Buttweld Fittings are mostly preferred for pressure piping systems. They are basically used in moderate to high temperature conditions. The ASTM A403 Gr WP304L Butt weld pipe fittings material covers the standard for wrought austenitic stainless steel fittings that are used for various pressure piping applications.

Corrosion Resistance

WP304L Buttweld pipe fittings and 304L Stainless Steel Stub End Type B as per MSS SP-43, lowest price in Dubai

There are two types of SA 403 WP 304L reducer s, namely concentric and eccentric and they different in their construction and appearance. The SS 304L concentric reducer reduces the pipe in the center, whereas the eccentric one reduces the pipe on the side. The concentric reducers are used in the vertical piping systems, whereas the eccentric Stainless steel 304L reducer is used for pipes that lay on racks.

The difference between sch 40 and sch 40s EN 1.4306 45° and 90° Buttweld Elbow lies in their strength. S in sch 40s stands for strength, and thus, they have larger thickness compared to the sch 40 WP304L Buttweld pipe fittings .
