Inconel 625 Pipes

Inconel 625 Pipe is a nickel chromium superalloy pipe that consists of at least 58% nickel and 20% chromium and controlled quantities of carbon, manganese, silicon, iron, sulfur, aluminum and titanium. This material has a great resistance to corrosion, oxidation and high temperatures. The material has a minimum yield strength of 517 Mpa and minimum tensile strength of 930 Mpa and this puts the material in the position to be used in industrious applications.

Inconel 625 Pipe is popular in high-stress services due to its high level of strength and stability even at high temperatures. It is particularly very effective in heat exchangers, condensers, boiler sections and other instruments that are subjected to high heat and pressure. The pipes and tubes are made according to ASTM B167, ASTM B829 and ASTM B517 specifications with sizes that follow ASTM, ASME and API.

Alloy 625 seamless tubing comes in size options of between 4mm to 219mm. Besides seamless pipes, there are also welded, fabricated, LSAW, ERW and EFW products. Welded and EFW pipes are made with a range of 5 mm to 1219.2 mm. Inconel 625 seamless pipes are normally available with a wall thickness of 0.5 mm to 20 mm though the pipes of larger diameter are normally provided with schedules

between 5 and 160. These pipes are available in different types, sizes, round and hydraulic, and length type, which include single random, two random and cut-to-length pipes. End finishes available are threaded, beveled and plain end finishes to meet various project requirements.
