A bushing is a type of bearing. Generally speaking, “bearings” facilitate movement between two components while reducing friction. Simple in design, a typical bearing has two surfaces that roll against each other, allowing the two mating parts to move without friction.
Little or no corrosion occurs in dry gases such as chlorine or hydrogen chloride at room temperature and high temperature. At temperatures up to 550C in these media, this alloy has proven to be one of the most corrosion resistant common alloys.
Bushings, also known as sleeve bearings, are just one specific type of bearing. They slide on the rod to provide extremely low friction movement. They are ideal for shock absorption and minimise energy consumption, noise and wear.
Alloy 600’s high chromium content makes it significantly more resistant to oxidation than pure nickel, while its high nickel content provides good corrosion resistance under reducing conditions. This alloy has a high level of resistance to stress and salt water, exhaust gases, and most organic acids and compounds.
Hastelloy C276 bushings are widely used in the harshest environments such as chemical processing, pollution control, pulp and paper, industrial and municipal waste treatment, and recovery of sour natural gas.
At elevated temperatures, the annealed and solution annealed alloys exhibit good oxidation resistance and high strength.
Considered one of the most versatile corrosion-resistant alloys available, Hastelloy C276 bushings exhibit excellent resistance in a variety of chemical process environments, including ferric and cupric chlorides, thermally contaminated organic and inorganic media, Chlorine, formic and acetic acid, acetic anhydride, seawater, brine and hypochlorite and chlorine dioxide solutions.
Hastelloy C276 bushings have excellent resistance to strong oxidizing salt solutions such as ferric chloride and cupric chloride. Alloy C-276 has excellent phosphoric acid resistance at all temperatures below boiling point and concentrations below 65%.
Hastelloy C276 bushings have high nickel and molybdenum contents to provide good corrosion resistance in reducing environments.
Hastelloy C276 has a low carbon content to minimize grain boundary carbide precipitation during welding to maintain corrosion resistance in the heat affected zone of the welded joint
Hastelloy C276 is resistant to localized corrosion such as pitting and stress corrosion cracking.
A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.
This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances.
INCONEL alloy 625 is designated as UNS N06625, Werkstoff Number 2.4856 and ISO NW6625 and is listed in NACE MR-01- 75.
Alloy 400 (UNS N04400) is a nickel-copper alloy with high strength (comparable to structural steel) and toughness.
They are used in plumbing fixtures such as domestic, commercial and industrial water supply lines, machinery and process equipment. They are also installed on the pump line and their sole purpose is to remove air blockages.
Nickel alloys pipe fittings are metals made from combining nickel as the primary element with another material. It merges two materials to deliver more desirable features, such as higher strength or corrosion-resistance. Because of its unique properties, it’s used in a variety of equipment spanning multiple industries.
Monel 400 operates in a wide range of acidic and alkaline environments and has excellent ductility and thermal conductivity. Its properties make it ideal for heavy-duty applications and those requiring a high melting point and toughness in the harshest conditions.
Monel 400 contains the same levels of nickel and copper as the natural nickel ore found.
Alloy 625 (UNS N06625) is available in Round Bar, Flat Bar, Extruded section, Pipe, Tube, Plate, Sheet, Strip, Plate, Hexagon, Forging Stock, Extruded Section, Wire and Powder.
