Types of 4" X 2"Butt Weld Reducer
When we talk about fittings used to reduce the two different diameter pipes ends, we have reducers, couplings, nipples and other special fittings. But the name reducer is particular in the same functional fittings with two but weld end. Differentiated by whether there central axis are on the same horizontal line or not, butt weld reducers can be divided into concentric ones and eccentric ones. So when we say 4" X 2" butt weld reducer, there are two possibilities, 4" X 2" concentric reducer and 4" X 2" eccentric reducer.
Material of Butt Weld Reducer
Since 4" X 2" butt weld reducer is the most commonly used reducing fitting, the frequently-used materials all can be applied in the manufacturing. Unconventional materials also can be used provided the available oral material, usually is steel plate or seamless pipes.

Surface Treatment Butt Weld Reducer
Depending one the material difference, the surface appearance will be different. Carbon steel just have a black color painting out side, alloy steel material will have similar surface treatment. These two may have other color painting, but need to be customized.
Carbon Steel Concentric and Eccentric Reducer
For stainless steel and high allot steel, we usually do sand blasting to make the surface clean and smooth, and the final product will be without painting out side. If customer need, we could also do drum sanding , but that only doable for small size materials.
