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.

HT PIPE is a leading manufacturer of the ASTM A182 Low Alloy Steel flanges as well as the other types of alloys. The ASTM A 182 specification specifies flanges for high pressure services.

A182-F11 belongs to the American standard pearlitic organization heat-resistant steel forgings

It can be used with other a335 gr P22 alloy tube types and fittings. SA 335 gr P22 alloy steel pipe has high heat resistance and low thermal expansion. This property of P22 metal tubing makes it suitable for use in the oil and gas industry, power industry, petrochemical industry and refineries where temperatures often fluctuate at high temperatures.

Weld Neck Flange is flanges that designed to be joined to a piping system by butt welding. This kind of flange include lots of specification.

ASTM A182 F5 belongs to the American standard Martensite type heat-resistant steel forgings, implementation standard: ASTM A182-2016

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.

A335 steel pipe can be used in NACE applications at high temperature and high pressure in sour environments, can be used in NACE-MRO 175 Sour Service, ideal for creep rupture applications, can handle high temperatures with very low elasticity.

Alloy 20 (Alloy 20) is an iron-based austenitic alloy developed to resist sulfuric acid corrosion. It has excellent resistance to sulfuric acid corrosion; it has strong resistance to phosphoric acid, nitric acid and chloride environments, chloride stress corrosion, pitting corrosion and crack corrosion. Therefore, alloy 20 has the name of anti-corrosion alloy; it has a wide range of applications: such as: chemical, food, medicine, power production and plastics industries will use it. For resistance to pitting corrosion and chloride corrosion, stress corrosion cracking problems, etc., alloy 20 is often used.

ASTM A193 Grade B7 is the standard material specification for chromium-molybdenum alloy steel fasteners for high-strength, high-temperature, and special-purpose applications. Grade B7 is a heat treated chromium molybdenum alloy steel with a minimum tensile requirement of 100 ksi, a yield strength of 75 ksi and a maximum hardness of 35 HRC. The ASTM A193 specification covers requirements for chemical composition, mechanical properties, hardness, heat treatment, and recommended nut washers for Class B7 fasteners. ASTM A193 Grade B7 is the broadest specification for fasteners, commonly found in bolts or pipes, pressure vessels, valves, flanges and fittings.

A335 grade P9 alloy steel round pipe is your best choice. It surrounds pipes made of alloy steel. It’s graded very well, making it unique. It has excellent properties such as toughness, durability, weldability, and low electrical conductivity.

Its greatest advantage is that it can be assembled without welding, which explains its use in low-pressure service at ordinary atmospheric temperatures and in highly explosive areas where welding creates a hazard.

These ASTM A182 Grade F5 Flanges gives extraordinary erosion resistance in, for instance, caustic and acidic applications which includes sulphuric and higher chloride environments. A182 Gr F5 Threaded Flanges are mostly used in utility services such as air and water. It is similar to the Slip-On flange, but the bore is threaded. Its greatest advantage is that it can be assembled without welding, explaining its use in low pressure services at ordinary atmospheric temperatures, and in highly explosive areas where welding create a hazard.

Alloy Steel AISI 4140 bar stock or forging stock to produce B7 headed and non-headed bolts. A193 Grade B7 is the most commonly used Bolt specification coupled with A194 Grade 2H Nuts for Bolting Carbon Steel pipeline. A193 B7 bolting is available in metric sizes from M6 to M180 and imperial sizes from 1/4 to 7 inches, in diameter.

The corrosion resistance of SA 335 P91 seamless pipe is much higher than that of carbon steel. Grade P91 is a reference for the chemical composition of alloy steels. A chromium-molybdenum steel, the chemical composition of ASTM A335 P91 alloy steel pipe consists of 9% chromium and 1% molybdenum and vanadium.
