Excellent Corrosion Resistant B16.9 ASTM A403 WP316L S31603 Reducer
ASTM A403 WP316L Fittings are used in various environmentally friendly applications where the corrosion of the fittings is low. TONG CHUANG is a leading supplier of the different types such as the A403 WP316L Reducer which is one of the most used types. The ASTM A403 gr WP316L is a lower carbon version of the 316 material. So the carbide precipitation while welding is less. This avoids localized corrosion after welding.
For these reasons， the Stainless Steel 316L Pipe Fittings are preferred for sea water， marine and other high corrosive applications. The fittings can range in shapes， size and types. There are different standards such as the ASTM B16.9 and others which govern the dimensions of the 316L SS Weld Fittings.

The ss 316L reducer is a pipe fitting that reduces the pipe line’s diameter. The reducer can be of different types. There are eccentric reducers which have the reduced end aligned with the side of the pipe line.
The concentric reducer reduces the diameter in alignment with the axis of flow. Depending on the need， the different types of SS 316l buttweld pipe fittings can be used. The applications range from domestic water supply to oil and gas industrial applications.
