Monel is a kind of corrosion resistant alloy with large dosage, wide use and excellent comprehensive performance. The alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium, and also has excellent corrosion resistance in hot concentrated alkaline solution. It is also resistant to corrosion of neutral solution, water, sea water, atmosphere and organic compounds. One of the most important characteristics of the alloy is that stress corrosion cracks do not occur in general, and the cutting performance is good. The structure of Monel alloy is single phase solid solution with high strength.

Nickel alloy tube is a tubular material made of an alloy of nickel and other metallic elements (such as copper, iron, chromium, molybdenum, etc.). This alloy tube has excellent corrosion resistance, high temperature strength and good mechanical properties, so it is widely used in various industrial fields.
In the nickel alloy tube, nickel is the main component, usually more than 80%, and the addition of nickel can improve the strength, corrosion resistance and high temperature performance of the alloy. The addition of other metal elements, such as iron, chromium, molybdenum, etc., can further enhance the properties of the alloy, such as improving strength and corrosion resistance.
Nickel alloy tubes are widely used in chemical, petroleum, energy, aerospace and other fields. For example, in the chemical industry, nickel alloy tubes can withstand acid-base corrosion and high temperature and high pressure environments, and are suitable for reactors, ammonia synthesis equipment, al

Titanium is a very active metal with low equilibrium potential and high thermodynamic corrosion tendency in media. But in fact titanium in many media is very stable, such as titanium in oxidation, neutral and weak reducing media is corrosion resistant. This is because titanium and oxygen have a very large affinity, in the air or oxygen-containing medium, titanium surface generates a layer of dense, strong adhesion, inert oxide film, protect the titanium matrix from corrosion. They heal or regenerate quickly even due to mechanical wear. This indicates that titanium is a metal with a strong tendency to passivate. The oxide film of titanium always keeps this property when the temperature of the medium is below 315℃.

Incoloy is suitable for all concentrations of sulphuric acid at low temperatures; In 50% ~ 70% concentration of caustic alkali solution (such as NaOH), it has good corrosion resistance and does not produce stress corrosion cracking. Inconel is suitable for various solutions and acids containing Cl -, and many media such as caustic alkali with concentration < 70%.

Inconel alloy is a nickel-ferrochrome nickel-base corrosion resistant and heat resistant alloy, which has the following characteristics:
Good resistance to reduction, oxidation, nitriding medium corrosion performance at room temperature and high temperature has good resistance to stress corrosion cracking performance good resistance to drying chlorine and hydrogen chloride gas corrosion performance below 650°C has high strength, good molding, easy to weld; In air, the maximum operating temperature is 1175°C

Hastelloy tube is a kind of special steel pipe with high strength, high wear resistance and high corrosion resistance, which is made of various metal elements alloyed, such as iron, carbon, chromium, nickel, molybdenum and so on. Among these elements, the content of chromium and nickel is higher, which can increase the corrosion resistance of the steel pipe; The addition of molybdenum can improve the strength and toughness of the steel pipe. Hastelloy tube is widely used in pipeline conveying system of petroleum, chemical industry, coal mine, electric power and other industries because of its excellent corrosion resistance, high strength and good mechanical properties. Especially in the oil and gas industry, Hastelloy tubes have excellent corrosion resistance and are especially suitable for acidic oil and gas fields and deep-sea oil and gas exploitation.
In addition, Hastelloy tube also has good thermal stability, can be used for a long time in high temperature and strong corrosive
