HastelloyC-276 (Hastelloy) is a tungsten-nickel-chromium-molybdenum alloy with extremely low silicon-carbon content and is considered to be an all-around corrosion-resistant aluminum alloy. The key moisture-resistant chlorine, various air-oxidizing fluorides, isopropyl titanate solutions, hydrochloric acid and air-oxidizing salts, have good corrosion resistance in ultra-low temperature and standing temperature sulfuric acid. Therefore, in the past 30 years, it has been widely used in extremely corrosive natural environments such as chemical plants, petrochemicals, flue gas desulfurization, pulp and paper industry, and environmental protection.

Corrosion resistance

The aluminum alloy has the following characteristics: 1. It has good corrosion resistance to most corrosive substances under the two conditions of air oxidation and repair. ¢ÚIt has good resistance to pitting corrosion, void corrosion and intergranular corrosion. The higher content of Mo and Cr makes the aluminum alloy resistant to corrosion by chloride ion content, and the W element further improves the corrosion resistance. At the same time, Hastelloy C-276 aluminum alloy is one of the only types of raw materials that are resistant to wet chlorine, hypochlorite and chlorine dioxide saturated solutions. Ester solution has obvious corrosion resistance. It is one of the very few raw materials that can be used as a hot sulfuric acid saturated solution.

All stainless steel fabrication can only be done using tools designed for stainless steel materials. Tools and work surfaces must be thoroughly cleaned before use. These precautions are necessary to avoid cross-contamination of stainless steel with easily corroded metals that may discolor the surface of processed products.

It is not useful in oxidizing acids, such as nitric acid and nitrous.

Type 304 stainless steel is a T 300 Series Stainless Steel austenitic. It has a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon. It is defined as a Chromium-Nickel austenitic alloy.304 stainless steel is used for a variety of household and industrial applications such as food handling and processing equipment, screws,[3] machinery parts, utensils, and exhaust manifolds. 304 stainless steel is also used in the architectural field for exterior accents such as water and fire features. It is also a common coil material for vaporizers.

Stainless Steel A403 WPS31254 contains higher chromium and low carbon content. Lower carbon means less chromium carbide precipitation due to welding. This steel type contains as low as 0.03% of carbon content and thus reduces its susceptibility to intergranular corrosion. This kind of steel can be continuously exposed to temperatures of about 1500 without appreciable scaling.

Stainless steel is an alloy of iron that is resistant to rusting. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel’s resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen.
A stainless steel pipe system is the product of choice for carrying corrosive or sanitary fluids, slurries and gases, particularly where high pressures, high temperatures or corrosive environments are involved. As a result of the aesthetic properties of stainless steel, pipe is often use in architectural applications.

Other available materials include silicone, rubber compounds, galvanized steel, and nylon. These sanitary fittings are primarily used to connect hoses to valves, water pumps, and deck drains.

In order to convey the pipeline, it is necessary to remove the straight hose in the pipeline. When using various pipelines, various pipelines must be used. When the pipeline is used, the elbow must be used to change the size of the pipeline. When bifurcating, the three-way pipe The flange connection used when the joint is used with various pipe joints, in order to reach the long-distance transmission pipeline, in order to reach the thermal expansion and cold contraction joint or effective connection aging of the pipeline, the long-distance expansion and cold contraction joint is used for the connection of the pipeline. , In the connection of various instruments, there are also the connectors and plugs of the instrument phase.

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.

They primarily provide resistance to chloride stress corrosion and chloride pitting corrosion. They have higher chromium and molybdenum content than other austenitic stainless steels.

Elbow A234 WPB are devided into two categories which define the distance over which they change direction.

Titanium is also a ductile metal, especially in an oxygen-free environment.

It¡¯s also ideal for sensitive industries such as food preparation and pharmaceuticals, as the risk of contamination is much lower.
