  • We have around 30 years experience in manufacturing of Niobium buttweld pipe fittings 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. Our products are widely used in oil & gas, petrochemical, refineries, power plant, shipbuilding, metallurgy, paper making and other industries.
  • A Niobium buttweld pipe fitting is a type of pipe fitting, which is designed to be welded on site to connect pipes together. Welding of a Niobium buttweld pipe fitting to pipes or other fittings is generally done to allow change in direction of the piping system. Niobium Buttweld fittings are generally identified or inquired in nominal pipe sizes with specified pipe schedule. Niobium Buttweld fitting’s dimensions and tolerances are defined as per ASME B16.9 standard. This helps create full penetration weld without any extra preparation needed for the Niobium buttweld fitting.
  • Manufacturing Niobium buttweld fittings – A Niobium buttweld pipe fitting is made by the process of hot forming that includes bending and forming to shape. The starting material of butt weld 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.

At Metallica Metals, we believe in selling in volume and increasing our customer base across the globe, enabling us to work on low margins. We have an extensive trader network across India, USA, Europe and the Middle East, who buy from us on a regular basis.
  • In addition to traders, we have many EPC contractors, companies and end users in various industries as our customers. We are leading Niobium buttweld fittings suppliers for various applications ranging from low/medium/high pressure or temperatures.
  • ASME 16.9 covers overall dimensions, tolerances, ratings, testing, and markings for factory-made wrought Niobium butt-welding fittings in sizes NPS 1⁄2 through NPS 48 (DN 15 through DN 1200). The term “wrought” denotes fittings made of seamless or welded pipes, tubing, plates, or forgings.

What is Niobium?

Niobium, also known as columbium, is a chemical element with the symbol Nb and atomic number 41. Niobium is a light grey, crystalline, and ductile transition metal. Pure niobium has a Mohs hardness rating similar to that of pure titanium, and it has similar ductility to iron. Niobium oxidizes in the earth’s atmosphere very slowly, hence its application in jewelry as a hypoallergenic alternative to nickel. Niobium is a rare, soft, malleable, ductile, gray-white metal. Niobium exhibits similar but slightly lower resistance against chemicals corrosive to tantalum. It must be placed in a protective atmosphere when processed at even moderate temperatures because it tends to react with oxygen, carbon, the halogens, nitrogen, and sulfur. The metal is inert to acids, even to aqua regia at room temperatures, but is attacked by hot, concentrated acids, and especially by alkalis and oxidizing agents. However, 90% of its total demand arises from the production of high-strength low-alloy steels, whereas rolled niobium–based products account for 4% and superalloys and compounds (oxides and chemicals) account for 3% each.

Prices for Niobium Buttweld Fittings

Prices for Niobium Buttweld Fittings are directly co related to prices of the raw materials such as iron ore, metal scrap, chromium, nickel and various other alloying elements. The production cost of heat resistant stainless steel and nickel alloy plates is high as they contain high amount of nickel and chromium. Meanwhile, mild steel material is among the lowest cost steel available, followed by carbon steel, 400 series stainless steels, aluminium, alloy steel, and 300 series stainless steel. Special alloys such as titanium, Inconel, Monel and Hastelloy cost very high as the nickel, chromium and moly content is very high.
