Eccentric Reducer

Size Range: 3/4" - 60" / DN20 - 1500

Thickness Schedule: SCH 10 - SCH 160, XXS

Standard: ANSI / ASME B16.9 & MSS SP-43

Availability:
Quantity:

ASME B16.9 is standard specification for butt welding fittings that covers BW concentric and eccentric reducer, elbow and tee. The dimensions range is from 3/4" to 24" in seamless type.

Compare with cone-shaped fitting that enlarges or reduces the diameter, it is not symmetrical about center line. Both of them are available in carbon steel, alloy steel, stainless steel and used in pipeline system for reducing the diameter from one size to larger or small size.


Buttwelding Fittings are used in a piping system to change direction or function of media, to branch off, reduce pipe size or attach auxiliary equipment. They are availbale in multiple types as elbow, tee, cap, eccentric reducer, stub end and oelt, that produced in cold and hot forming based on ASTM A403 and ASTM A234 specification.


ASTM A403 WP304 & 316 Stainless Steel Pipe Fittings


The specification of ASTM A403 covers common stainles steel grades WP304 & WP316 that used for pressure piping. Customers need to indicate seamless or welded type while purchasing kinds grades fittings, such as eccentric reducers, buttwelding tee & cross, steel pipe bend and elbow.


ASTM A234 Carbon Steel and Alloy Steel Pipe Fittings


This specifiation covers ASTM A234 carbon steel and alloy steel fittings of semaless and welded construction by the standard of ASME B16.9. These eccentric reducer fitting is for using in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures.
