Chemical gas - Import export

Customers in aerospace, oil and gas, chemical processing and other industries all rely on Superior Tube to supply precision thin wall tubing which they use to make bellows and convoluted tubing for a variety of applications. Our convoluting grade tubes are made from several alloys such as Inconel 625 and stainless steel 321. The tubes are then hydro or mechanically formed into flexible hoses, which are often used to transport fluids and gases in various industries. Superior currently produces bellows and convoluting grade tubing from 1.0” in outside diameter down to under .250” OD with wall thickness as light as .003”. If you have demand within or outside of this range, please contact us so we can provide a solution. Please note that we have a minimum order value of £10,000.

The chemically stable and high-temperature resistant nickel-chromium-molybdenum alloy 2.4605 (alloy 59) is mainly used in the chemical industry, flue gas desulphurisation plants, paper industry. Alloy 59 is a nickel-chromium-molybdenum alloy with excellent corrosion resistance and high mechanical strength. The alloy has excellent resistance to both oxidizing and reducing media, and possesses superior resistance to chloride pitting and stress corrosion cracking. The alloy is widely used in the most severe environments. Some applications include: flue gas scrubber components, bleach plant and digester components for the pulp and paper industry, sour gas handling equipment, sulfuric acid coolers, waste incinerators and seawater equipment. Please note that we have a minimum order value of £10,000.

Grade 316 is the standard molybdenum-bearing grade, second inoverall volume production to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. Grade 316L, the low carbon version of 316 and has very high immunity from sensitization (grain boundary carbide precipitation). It is extensivly used in the oil and gas and chemical industries for its cost effective corrosion resistance and ease of fabrication. There is commonly no appreciable price difference between 316 and 316L stainless steel. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures. Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures. Please note that we have a minimum order value of £10,000.

17-4 PH®, a wrought compressed stainless steel powder, combines high strength and high hardness with excellent corrosion resistance, fracture toughness and heat treatment properties. When machined, 17-4 PH® produces long, gummy chips. While soft and ductile in an annealed condition, it is capable of high hardness properties with a single precipitation or aging treatment. Applications 17-4 PH® is ideal for manufacturing aircraft fittings, braces, chemical processing components, coupling, fasteners, gas turbines, gears, hydraulic actuators, jet engines, nuclear reactor parts, pump shafts, rocket and missile components, valve stems and wear rings. The physical properties of 17-4 PH® stainless steel make it weldable by common fusion and resistance techniques. Among members of the precipitation hardening class of stainless steels, 17-4 PH® has the best weldability.
