The pipes are having good stress corrosion cracking and pitting resistance ability.

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.

Hastelloy C22 machined gaskets also have the best resistance to environments that encounter reducing and oxidizing conditions in the process stream. Hastelloy C22 round washers can be welded, forged, hot upset and impact extruded. Typical chemical process industry (CPI) applications for Hastelloy C22 punch gaskets include reactors, heat exchangers and columns.

Los fabricantes de tuberias Hastelloy recomiendan la tuberia soldada Hastelloy Astm B626 C276 por su resistencia a los compuestos de cloro.

Prefabrication is the practice of assembling components of a structure in a workshop or other assembly facility before transporting to site for erection.

HASTELLOY C276 is one of the few alloys resistant to wet chloride gas, hypochlorite and chlorine dioxide solutions.

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 is molybdenum and nickel alloys family additional member with greater hydrochloric acid resistance at various concentrations and temperatures. It is withstanding formic, sulphuric and phosphoric acid as well as non-oxidizing acids.

The high molybdenum content of Hastelloy?* C276 provides the alloy with its excellent resistance to pitting and crevice corrosion.

Incoloy alloy is applied as the prefix name to several highly corrosion resistant high temperature strength metal alloys produced by Special Metals Corporation. 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

Alloy C-276 prevents the formation of grain boundary precipitates in the weld heat affected zone, making it useful in most welding conditions for chemical processes.

Bending a pipe or tube using a stationary die while a counter die bends the material around the stationary die.

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

Hastelloy C22 bar contains a high amount of nickel-molybdenum-chromium superalloy as well as tungsten and is designed to provide excellent corrosion resistance in a wide range of harsh environments. It is very resistant to corrosion in immersion environments and is used for chemical applications in the as-welded state.

La aleacion tambien es resistente a soluciones y compuestos de cloruro, muchos de los cuales son altamente corrosivos. Por ejemplo, los reductores de aleacion de niquel C276 son resistentes no solo a los medios organicos e inorganicos termicamente contaminados, sino tambien a los cloruros ferricos y c¨²pricos, asi como al cloro, el agua de mar y la salmuera.

C2000 flanges have better temperature capabilities in hydrofluoric, sulfuric, and diluted hydrochloric acids due to the addition of copper.

The flanges are furnished in solution heat treated circumstances, thus these are heat treated at 2150 degree F and get cooled rapidly.

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.

C22 nickel alloy fasteners offer better overall corrosion resistance than its sister alloy Hastelloy C-276, and more specifically, it offers better protection when used in certain saturated wet chlorine environments. Additionally, its high chromium content provides C22 fasteners with better resistance to oxidative media than C276. This makes it excellent resistance to chloride-induced pitting, although in most cases C-276 fasteners are a more cost-effective option due to their availability, especially in sizes smaller than 1/ 2″ case.
