HT PIPE offers all types of bolts, screws, studs, threaded rods, nuts, washers and custom bolts in Hastelloy B3.

Nickel- and cobalt-based corrosion-, temperature- and wear-resistant alloys, such as Hastelloy B2, are classified as moderate to difficult when machined, but it should be emphasized that these alloys can be produced at satisfactory speeds using conventional production methods processing. During machining, these alloys harden rapidly, generate high heat during cutting, weld to the cutting tool surface, and provide high resistance to metal removal due to their high shear strength.

Hastelloy is a corrosion-resistant nickel alloy that contains other chemical elements such as chromium and molybdenum. This material has high temperature resistance and excellent corrosion resistance. Hastelloy C276 is one of the Hastelloy grades used in the oil and gas industry.

Other corrosives Hastelloy C-22 has resistance to are oxidizing acid chlorides, wet chlorine, formic and acetic acids, ferric and cupric chlorides, sea water, brine and many mixed or contaminated chemical solutions, both organic and inorganic.

Nickel Alloy C-276 and Hastelloy C-276 can be welded by all common welding methods (oxyacetylene is not recommended).

Exposures like this are regularly experienced during heat treatments that are linked with fabrication.

Hastelloy C276 is resistant to localized corrosion such as pitting and stress corrosion cracking.

INCONEL alloy C-276 (UNS N10276/W.Nr. 2.4819) is known for its corrosion resistance in a wide range of aggressive media.

Hastelloy B2 prevents the formation of grain boundary carbide precipitates in the weld heat affected zone, making it suitable for most chemical process applications in the as-welded condition. The heat affected weld zone reduces the precipitation of carbides and other phases to ensure uniform corrosion resistance.
Alloy B2 also has excellent resistance to pitting and stress corrosion cracking.

ASTM B619 UNS N10276 C276 pipes are also available in other shapes such as square, rectangular and hexagonal pipes. 2.4819 Hastelloy C-276 Alloy C276 pipe is used in applications where bending should not reduce strength. These ASTM B619 N10276 seamless pipes are mainly used to transport fuels from one place to another, as well as chemicals in different parts of processing plants.

The greatest advantage of Hastelloy B3 bolts compared to B-2 alloys is their ability to maintain excellent ductility during transient exposure to intermediate temperatures.

Hastelloy B2 studs have poor corrosion resistance to oxidizing environments and are therefore not recommended for use in oxidizing media or in the presence of iron or copper salts as they may cause rapid premature corrosion failure.

Hastelloy C-276 is the most common corrosion resistant material currently available, but it is not foolproof. Metals should not be exposed to high temperature, strong acid environment. Also, it is easier to work with cold working practices; hot working makes it easier to harden. If hot working, the temperature should be maintained between 1600¡ãF and 2250¡ãF.

When standard 90-degree elbows won¡¯t work with your system design or space requirements, bent pipes and tubing are an excellent routing option.

Prefabrication can be of many different types and undertaken at many different scales, from fabrication of small components and sub-assemblies through to large welded and bolted assemblies requiring significant logistical challenge to transport to site

Hastelloy B2 pipe bend has excellent resistance to all temperatures and concentrations of hydrochloric acid.

Hastelloy C22 fasteners are a general-purpose grade composed of chromium, nickel, molybdenum and tungsten alloys. These designs are designed to increase resistance to pitting, stress corrosion cracking (SSC) and crevice corrosion cracking. Alloy C-22 has excellent resistance to a variety of chemical process environments, including strong oxidizing agents such as ferric and cupric chlorides, chlorine, hot fouling solutions (organic and inorganic), formic and acetic acid, acetic anhydride, and seawater and Brine solution. C-22 alloy resists the formation of grain boundary precipitates in the weld heat affected zone and is therefore suitable for most chemical process applications in as-welded conditions.

Nickel alloys are excellent for heat exchangers in the chemical processing and nuclear industrie.Hastelloy Piping Systems are widely accepted by plant operations management and maintenance specialists who appreciate their toughness and ability to withstand very aggressive fluids.

Alloy C22 is one of the most corrosion-resistant alloys available, even outperforming C276 and 625. It is resistant to almost all reducing and oxidizing environments, including strong oxidizers, seawater, and organic acids.

Nickel alloys are excellent for heat exchangers in the chemical processing and nuclear industries. They’re used in steam generator tubing in the nuclear power industry, in high-temperature aircraft systems, and in oil and gas extraction programs where corrosion-, pressure- and temperature-resistant tubing is required

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

B2 has significantly lower carbon, silicon and iron compared to its¡¯ predecessor, Alloy B (UNS N10001), making the alloy less susceptible to decreased corrosion resistance in the weld zone, in the as-welded condition.

Hastelloy B3 Weld Neck Flange is not recommended for use in the presence of ferric or cupric salts because these salts can cause premature failure.

In the case of Hastelloy-C276, the corrosion product was primarily a protective chromium oxide scale, although slightly thicker regions of the same oxide formed at the site of microcracks on the metal surface. Very little carburization was observed in this alloy before exposure for at least 1000 hours.

Although there are several variations of the Hastelloy nickel alloy, Hastelloy C-276 is by far the most widely used.

Nickel alloys are some of the most useful materials for manufacturing technically superior pipes and tubes for industrial applications. Their inherent properties make them viable for a wide range of uses. Nickel alloys are exceptionally corrosion resistant and can be used in high-temperature environments.

The premium composition of molybdenum and nickel content of c276 is used to make nickel steel alloys. It helps resist crevice and pitting corrosion in reducing environments. Chromium, on the other hand, is used to impart resistance to oxidizing media.
