As an ISO-certified, TÜV-approved and MSME-registered company, we can manufacture and export up to 100 tonnes per month, serving customers across 85+ countries with inspection and material documentation available as required.
What Are Butt Weld Reducer Fittings?
Butt weld reducer fittings are pipe fittings that connect a larger pipe to a smaller pipe by welding the bevelled end of the fitting directly to the bevelled end of each pipe. The two ends meet face to face, and a full-penetration weld joins them. The body between the two ends tapers from the large diameter to the small diameter.
Two shapes are available. A concentric reducer keeps both ends on the same centre line, and an eccentric reducer offsets the small end so one side stays flat. Reducer sizes are written with the large end first, for example 8″ × 6″, and the fittings are manufactured to standards such as ASME B16.9, which covers dimensions and tolerances. Wall thickness, material grade and pressure capacity depend on the fitting specifications, piping design and operating conditions.
Butt Weld Reducer Fittings
High-quality butt weld reducer fittings are available in stainless steel, carbon steel, alloy steel, duplex and nickel alloys, in concentric and eccentric designs. Offered in various sizes and grades, including SS 304, 316, ASTM A234 WPB, Duplex 2205 and Inconel 625, these fittings meet industrial piping requirements for strength, durability and reliable performance.
