Butt Weld Pipe Fittings

C22 can be hot worked or cold worked. However, C22 work-hardens rapidly. Therefore, cold working must often be performed in stages with intervening anneals. Parts should be annealed after cold working.

C-22 is used in severely corrosive media with high chloride and temperature applications such as buffer solutions, active pharmaceutical ingredients (API), fabric softeners, cleaning supplies, and fish, soy and chili sauce.

The exceptional corrosion resistance of C22 has promoted its use in many different markets wherever harsh environments are encountered, including the chemical process, pharmaceutical, food processing, oil and gas, power generation, and the paper industries.

C-22 is a great alternative when superaustenitic stainless steels (AL-6XN, 904L, and 254 SMO) and duplex stainless steels (2205 and 2507) will not withstand extremely aggressive media. This is because it is a nickel-chromium-molybdenum-tungsten alloy with better overall resistance to uniform and localized corrosion than any other Ni-Cr-Mo alloy, like Hastelloy C-276, C-4, and alloy 625.

Hastelloy B2 pipe bend resists 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 zones have reduced precipitation of carbides and other phases to ensure uniform corrosion resistance.

Alloy B2 also has excellent resistance to pitting and stress corrosion cracking.

Superior resistance to hydrochloric acid, aluminum chloride catalysts and other strongly reducing chemicals. Excellent high-temperature strength in inert and vacuum atmospheres.

Hastelloy B2 pipe bend is a nickel-molybdenum alloy particularly suited for equipment handling reducing chemical environments.

Applications in the chemical process industry involving sulfuric, phosphoric, hydrochloric and acetic acid.

Super alloys are also known as high performance alloys. They contain many elements in a variety of combinations designed to provide unique material properties for specific applications.

Hastelloy B2 is a nickel-molybdenum alloy with significant resistance to reducing environments, such as hydrogen chloride gas and sulfuric, acetic and phosphoric acids.

These alloys can function at very high temperatures and in severe mechanical stress environments, and also where high surface stability is required. They have high creep and oxidation resistance.

Hastelloy B2 pipe bend provides resistance to pure sulfuric acid and a number of non-oxidizing acids. The alloy should not be used in oxidizing media or where oxidizing contaminants are available in reducing media.

Strengthening of super alloy Hastelloy B2 pipe bend is performed by solid-solution hardening, work hardening, and precipitation hardening methods.

Hastelloy B2 pipe bend is a solid solution strengthened, nickel-molybdenum alloy, with significant resistance to reducing environments like hydrogen chloride gas, and sulfuric, acetic and phosphoric acids.

HASTELLOY(r) B-2 is a wrought nickel-molybdenum alloy that can be used in the ¡®as welded¡¯ condition.

The Molybdenum of Hastelloy B2 pipe bend is the primary alloying element which provides significant corrosion resistance to reducing environments.

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

This nickel steel alloy can be used in the as-welded condition because it resists the formation of grain-boundary carbide precipitates in the weld heat-affected zone.

This nickel alloy provides excellent resistance to hydrochloric acid at all concentrations and temperatures. In additions, Hastelloy B2 pipe bend has excellent resistance to pitting, stress corrosion cracking and to knife-line and heat-affected zone attack.

Alloy B2 pipe bend provides resistance to pure sulfuric acid and a number of non-oxidizing acids.

These salts may develop when hydrochloric acid comes in contact with iron and copper. Therefore, if this alloy is used in conjunction with iron or copper piping in a system containing hydrochloric acid, the presence of these salts could cause the alloy to fail prematurely.

Industry users like the resistance to a wide range of organic acids and the resistance to chloride-induced stress-corrosion cracking.

The combination of very low corrosion rates in high-velocity sea water and high strength make alloy K-500 pipe bend and elbow particularly suitable for shafts of centrifugal pumps in marine service.

Typical application for MONEL K500 which takes advantage of high strength and corrosion resistance are pump shafts, impellers, propeller shafts, valve components for ships and offshore drilling towers, bolting, oil well drill collars and instrumentation components for oil and gas production. It is particularly well suited for centrifugal pumps in the marine industry because of its high strength and low corrosion rates in high-velocity seawater.

MONEL K500 is non-magnetic. MONEL K500 should be annealed when welded and the weldment then stress relieved before aging.

This nickel-copper alloy is precipitation hardenable due to the addition of aluminum and titanium. It combines the corrosion resistance of Monel 400 with the added benefits of superior strength and hardness (derived from its age-hardenability). Monel K-500 is also known for its ease of fabrication compared to other superalloys, and the fact that it is essentially nonmagnetic even at low temperatures.

Monel K500 pipe bend and elbow are virtually nonmagnetic, even at quite low temperatures

MONEL K500 is a age-hardenable Nickel-Copper alloy which combines the corrosion resistance of Alloy 400 with high strength corrosion fatigue and erosion resistance.
