Hastelloy is a registered trademark name of the Haynes International, Inc. The trademark is used as the prefix name of a range of 22 different high corrosion-resistant metal alloys, simply grouped by the metallurgical industry under the material term “superalloys” or “high-performance alloys. The dominant alloying ingredient is nickel, the typical transition metal. The other alloying ingredients are added to nickel in each of these subcategories of this trademark designation and include the different percentages of the elements molybdenum, chromium, cobalt, iron, copper, manganese, titanium, zirconium, aluminium, carbon, and tungsten. The primary and basic function of the Hastelloy super alloys is that of strengthened survival under high-temperature, high-stress usage in a moderately to extremely corrosive, and/or erosion-prone environment where iron-based alloys would fail, including the pressure vessels of some nuclear reactors, chemical reactors, distillation equipment, and pipes and valves in chemical industry. Though it is a super alloy, Hastelloy experiences degradation due to fabricating and handling. Electro polishing or passivation of Hastelloy can improve corrosion resistance.

Butt Weld Fitting

A pipe fitting defined as a part used in a piping system, for changing direction, branching or for change of pipe diameter, and which is mechanically joined to the system. There are many different types of fittings and they are the same in all sizes and schedules as the pipe. Buttweld (BW) fittings whose dimensions, dimensional tolerances et cetera are defined in the ASME B16.9 standards. Light-weight corrosion resistant fittings are made to MSS SP43.

BEVELLED ENDS: The ends of all buttweld fittings are bevelled, exceeding wall thickness 4 mm for austenitic stainless steel, or 5 mm for ferritic stainless steel. The shape of the bevel depending upon the actual wall thickness. This beveled ends are needed to be able to make a “Butt weld”.

This is the most widely used and most versatile, corrosion resistant alloy. Very good resistance to reducing, and mildly oxidizing corrosives. Excellent stress corrosion cracking resistance with exceptional resistance to localized attack.

A Ni-Cr-Mo alloy used in the most corrosive environments. They are also an excellent corrosion resistance to reducing and oxidizing environments. Hastelloy c276 are well suited for hydrochloric and sulfuric acid environments. Strong resistance to stress and corrosion cracking. Excellent mechanical properties at elevated temperatures. Hastelloy c276, such as the Hastelloy c276 Butt Weld Fitting, are made from nickel-molybdenum-chromium alloy that is generally considered as a versatile highly corrosion resistant alloy. Hastelloy c276 Butt Weld Fitting have excellent corrosion resistance in both oxidizing and reducing media which makes it well suited for a variety of strong corrosive applications. The Hastelloy c276 Butt Weld Fitting also have an exceptional resistance to both sulfuric acid and hydrochloric acid.

Hastelloy c276 resist some of the most severe media, they are often utilized in chemical processing applications where acid chlorides, solvents, formic and acetic acids, acetic anhydride, wet chlorine gas, hypochlorite’s, chlorine solutions and phosphoric acid are used. Chemical processing applications, Hastelloy c276 is the most common grade and one of the most corrosion resistant nickel alloys – exceeding that of most other nickel alloy grades like Inconel or Monel.

Production Process

We produce large volume at crest in a 3 shift plan, which means, we used to target 1.3 million assembled units on per month basis. We have in house testing provision e.g. Hardness Test, PMI Machine, Ultrasonic Testing, Mechanical test, spectro machine, Hydrostatic Testing, manual inspection of gauge and Pressure testing. Our production varies from snubber, condensate pots, manifolds, instrumentation valves and custom designed valves. Tube Fittings Manufacturers can be fabricated in threads like NPT, BSPT & BSPP. Butt Weld Fitting are in need from various industries like Food processing, Beverages, Chemicals, Submersible pumps, Electric furnace, Pharmaceutical machinery, Construction and fabrication. This specification covers the requirements for Butt Weld Fitting, Pipe cap screws, and studs 0.25 to 1.50 in., inclusive, in nominal diameter in a number of alloys in common use and intended for service applications requiring general corrosion resistance.

This type of alloy also has wide uses in gas turbine engines for combustion and other machines like transition ducts, combustor cans, spray bars, after-burners, tail pipes and cabin heaters and various other purposes. Hastelloy c276 Butt Weld Fitting are most commonly used in the chemical industry for catalyst support grids, furnace baffles, tubing for chemical operations and flash drier components. The other applications include in that in petrochemical, pharmaceutical industries, mining and for nuclear and solar power generating factories. In many cases, they are used as heat-resistant materials and the like. It is widely recommended for the use of heat furnace applications because it has unusual resistance to oxidizing, reducing and neutral atmospheres.

Audacious resistance to corrosion is visible in these Butt Weld Fitting. It has excellent forming and welding features due to its high ductility, it can be used in cryogenic conditions or temperatures and likewise, in extreme heat temperatures. They Butt Weld Fitting can also be used in high stress environments or erosion prone surroundings. They also have a very good impediment to non-oxidizing acids such as hydrochloric acid or sulphuric acid. Hastelloy c276 Butt Weld Fitting also provides protection to outer kinetic forces that tend to destroy or consume other material. It is typically known as a tensile material and also known for its adaptability.
