NXF UNS N10665 ALLOY B/B-2 Outer Diameter DN15-1200 Pressure Class3000-9000 Forged Pipe Fitting Alloy B2 Thread Hex Head Bushing

Alloy B2 Introduction:

Alloy B2 is a nickel-molybdenum alloy with significant resistance to reducing environments, such as hydrogen chloride gas and sulfuric, acetic and phosphoric acids. Alloy B2 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. Premature failure may occur if Alloy B2 is used where iron or copper is present in a system containing hydrochloric acid.Industry users like the resistance to a wide range of organic acids and the resistance to chloride-induced stress-corrosion cracking.Alloy B2 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.

Alloy B2 Applications:

Superior resistance to hydrochloric acid, aluminum chloride catalysts and other strongly reducing chemicals. Excellent high-temperature strength in inert and vacuum atmospheres.Hastelloy B2 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. Temperature uses vary from ambient temperature to 1500°F depending on the environments (please call for technical advice).

Hex Head Bushing Introduction:

Threaded fittings are pipe connection components with threads, widely used in industrial and domestic fields. Their main function is to simplify the pipe connection process and reduce maintenance costs. There are more than ten types of threaded fittings, including threaded elbows, tees, unions, etc. Industrial-grade products are mostly made of metal materials (such as carbon steel and stainless steel), while domestic-grade ones are made of plastic materials such as PVC and PPR This fitting adopts a threaded sealing structure, consisting of a coupling nut, a conical cavity, and a sealing ring with a knife edge. The thread strength is enhanced through cold working hardening, and its tensile performance exceeds the standard of the base material. It is compatible with BSP internal and external thread connection methods, supporting specifications from 3/8" to 4", and can withstand a working pressure of PN10. The core design includes prefabricated production, safe construction without electricity or fire, and adaptability to operation in dense and narrow spaces. It can connect HRB335/400 grade reinforcing bars of different directions and diameters. The ring knife reinforcement of the sealing ring is designed with a 45°-90° inclined surface. During assembly, a counterfeit-proof indentation is formed by transferring the component to achieve quality traceability [1]. Some models have NPT standard external thread, using a 45-degree conical structure to achieve self-sealing, suitable for low-pressure systems with a pressure lower than 1000 psi.
