Buttweld Pipe

in size ranging from 1/2” to 60”, schedule from Sch5s to SchXXS. Metallica specializes in manufacturing elbows, tee, reducer, caps, crosses, stub ends, etc conforming to ASME, ANSI, and DIN standard. We also produce custom size pipe fittings made according to drawings from our clients. Common material for buttweld fittings are carbon steel, alloy steel, stainless steel, super austenitic, duplex, super duplex, nickel alloys, titanium, and aluminum etc. Our products are widely used in oil & gas, petrochemical, refineries, power plant, shipbuilding, metallurgy, paper making and other industries.

is a type of pipe fitting, which is designed to be welded on site to connect pipes together. Welding of a buttweld pipe fitting to pipes or other fittings is generally done to allow change in direction of the piping system. Buttweld fittings are generally identified or inquired in nominal pipe sizes with specified pipe schedule. Buttweld fitting’s dimensions and tolerances are defined as per ASME B16.9 standard. All buttweld pipe fittings have beveled ends as per ASME B16.25 standard. This helps create full penetration weld without any extra preparation needed for the buttweld fitting.

– A buttweld pipe fitting is made by the process of hot forming that includes bending and forming to shape. The starting material of buttweld fitting is a pipe that is cut to length, heated and molded into specific shapes by means of dies. Heat treatment is also done to remove residual stresses and obtain desired mechanical properties. Sch 10 fittings are also more common in stainless steel buttweld fitting, while SCH 40 is common for carbon steel buttweld fittings.
