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%.

738 Inconel tube is a precipitation-hardened nickel-based cast superalloy with excellent high temperature strength and corrosion resistance, and its lasting strength can be comparable to Inconel 713C alloy. Due to the high chromium content, the thermal corrosion resistance and oxidation resistance of the alloy is better than that of 713C alloy, and it can meet the high temperature use requirements of modern aviation engines, and the use temperature can reach 980℃.

In addition, the 738 Inconel alloy tube also has good weldability and castability, and can be prepared into various high temperature parts such as precision cast turbine blades, guide blades and integral turbines. The preparation process includes two steps: solution treatment and aging treatment.

4400 Monel tube is a nickel-copper alloy, also known as UNS N04400, with high strength, high corrosion resistance and high wear resistance. It is more resistant to the corrosion of reducing media than pure nickel, and more resistant to the corrosion of oxidizing media than pure copper. It has good corrosion resistance to sulfuric acid and phosphoric acid, especially good corrosion resistance to chloric acid, and excellent corrosion resistance to hot concentrated alkali. Therefore, it is widely used in cutting-edge industrial fields such as petrochemical industry, nuclear industry, and national defense industry.

Nickel alloy pipe is a kind of pipe widely used in heavy industry and light industry. It is an alloy made of copper, iron, manganese and other elements added to metal nickel as a matrix. Nickel alloy tube is characterized by good corrosion resistance, silver white, edge silk material.

The advantages of nickel alloy tubes are:

High density, so its heat resistance is better.
It has high strength, good corrosion resistance, heat resistance and toughness.
It has good tensile strength, which is 3-4 times that of ordinary pipes.
It has good corrosion resistance and heat resistance, and will not be corroded because of changes in acidity and alkalinity in the environment, and the heat resistance is much higher than that of ordinary pipes, and can maintain higher temperatures.
Production only requires low-cost materials and simple processes, the cost is very low, so unique competitiveness.
In the process of use, the economic benefit is better than other pipes.

Monel alloy tube is a nickel alloy tube, adding copper, iron, manganese and other elements to the metal nickel matrix.

Monel alloy tube is a kind of corrosion resistant alloy with large amount, wide application and excellent comprehensive properties. It has excellent corrosion resistance to hydrofluoric acid and fluorine gas medium, and also has excellent corrosion resistance to hot concentrated lye. At the same time, it is also resistant to corrosion of neutral solution, water, seawater, atmosphere, organic compounds, etc. An important feature of the alloy is that it generally does not produce stress corrosion cracks and has good cutting performance. Monel alloy tube is mainly used in valve stem, pump shaft and impeller, conveyor scraper, oil well drilling ring, elastic parts, valve pad and so on.

Titanium alloy pipe is made of titanium alloy pipe, titanium alloy can be divided into three categories according to the organization:
Aluminum and tin are added to titanium.
Alloy elements such as aluminum, chromium, molybdenum and vanadium are added to titanium.
Elements such as aluminum and vanadium are added to titanium.

They have high mechanical properties, excellent stamping performance, and can be welded in various forms, the strength of the welded joint can reach 90% of the strength of the matrix metal, and the cutting performance is good. Titanium pipe has high corrosion resistance to chloride, sulfide and ammonia. The corrosion resistance of titanium in seawater is higher than that of aluminum alloy, stainless steel and nickel-based alloy. Titanium water impact resistance is also strong.

Hastelloy tube is a kind of nickel-based corrosion resistant alloy, mainly divided into nickel-chromium alloy and nickel-chromium molybdenum alloy two categories, with excellent comprehensive mechanical properties and better corrosion resistance. It is widely used in aviation and chemical fields.

Hastelloy tube is made of Hastelloy material cross-section is round, hexagonal, octagonal and other shapes of the bar material can be processed into bolts, nuts, gaskets, flanges, elbows and other products, while it uses chromium molybdenum as the main alloying element, designed to improve the adaptability to various media and temperature, and for different industry applications have been specially optimized. At the same time, Hastelloy rod also has good processing and welding performance, which is convenient for on-site maintenance.

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
