• Nickel & Monel® Pipe & Tubes
Ranging from chemical and pharmaceutical manufacturing to food processing, Alloy 20 pipe is an austenitic nickel-iron-chromium super alloy that combines copper with molybdenum. Also known as Carpenter 20 and Incoloy® 20, this pipe is ideal for acidic environments - especially when sulfuric, phosphoric, or nitric acids are heavily processed. This also makes it the preferred choice for piping material where applications are dependent on superior corrosion, crevice, and pitting resistance. Alloy 20 pipe is widely adopted for food production as well as synthetics manufacturing for explosives, chemicals, and gasoline.

Alloy 20 Pipe is available in Seamless or Welded from Size ranges 1/8" up to 26". Listed below are common sizes. Please contact for sizes not listed.
