TONG CHUANG GROUP is engaged in manufacturing of a wide range of Butt Weld Fitting that is available in varied types such as L/R & S/R elbow， tee， concentric and eccentric reducers， reducing elbow & tee， cross and caps.
Sourced from reliable vendors， these fittings are highly acknowledged for their high tensile strength， durability and accurate alloy composition. These find application in several industries such oil & gas， automobile， acid & chemical， pharmaceutical and cement industries. We are known for our butt welding fitting pieces.
The Stainless Steel 304L material is the low carbon version of the 304 material. The difference in carbon content affects their corrosion resisting properties. The 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.
