Hastelloy tubing is suitable for applications in the chemical processing, pharmaceutical, agricultural, food, petrochemical and power industries. Hastelloy piping is often specified for highly corrosive industrial applications and is often used in processes where chloride is a component.

Hastelloy offer very good resistance to strong reducing and moderately oxidizing corrosive acids, as well excellent stress corrosion cracking resistance and resistance to localized attack.

Used when large radius bends or curves are required, this method passes a piece of pipe or tube through a series of three rollers in a pyramid configuration to achieve the desired curve.

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.

Hastelloy X alloy is a chromium-iron-nickel-molybdenum superalloy with excellent high temperature efficacy, machinability and oxidation resistance.

Hastelloy C-4 is a nickel-chromium-molybdenum alloy with outstanding high temperature stability. It has high ductility and corrosion resistance. It’s high temperature resistance up to 1900 ¡ãF (1038 ¡ãC) makes it suitable for most chemical process application in the “as” welded condition.
Like other nickel alloys, it is ductile, easy to form and weld, and possesses exceptional resistance to stress corrosion cracking in chloride-bearing solutions (a form of degradation to
which the austenitic stainless steels are prone). With its high chromium and molybdenum
contents, it is able to withstand both oxidizing and non-oxidizing acids, and is resistant to
pitting and crevice attack in the presence of chlorides and other halides.

C276 is forged between 2250/1750oF (1230/955oC) and then soaked at the forging temperature for 30 minutes per inch of billet or ingot section thickness. Forging should begin immediately, the billet is removed from the reheat furnace, a 25/40% reduction helps retain as much internal heat as possible. For optimum corrosion resistance, forged parts should be subsequently annealed. See Heat Treatment.

Hastelloy B3 Spacer Flanges does not rust, because of the interaction between its alloying elements and the environment.

Steel Plate are often used for structural and construction applications, pressure vessels, marine and offshord equipment, and military applications. The grade, elements and parameters of a steel plate are also important in how it is used.
Steel plates are classified by thickness: thin plate, medium plate, thick plate and extra-thick plate.
Thin steel plates are steel plates with a thickness between 0.2-4mm produced by hot rolling or cold rolling, and thick steel plates are those with a thickness of more than 4mm
The general name of the good board.
Thin steel plate refers to a steel plate with a thickness of not more than 3 mm. The commonly used thin steel plate thickness is 0.5-2MM, which is divided into sheet and coil supply. Thin
The steel plates are generally B-type steels, cold-rolled or hot-rolled steel plates with steel grades B0-B3. Requirements for thin steel plates: smooth, smooth surface, thick
The degree of uniformity, allowing a tight iron oxide film, must not have cracks, scarring and other defects. The process is divided into hot rolled sheet steel and cold rolled sheet
plate. Mainly used in Changlin Dongfeng fans, automobiles, electrical equipment, vehicles, agricultural machinery, containers, steel furniture, etc.
Thick steel plates refer to steel plates with a thickness greater than millimeters. Thick steel plate is divided into extra-thick steel plate and medium-thick steel plate.
Medium and heavy steel plates refer to steel plates with a thickness greater than 3 mm and less than 50 mm. Medium and thick steel plates are mainly used in shipbuilding, boilers, bridges
Armor and high-pressure vessel shells, etc.
Extra-thick steel plate refers to a steel plate with a thickness of not less than 50 mm. Extra-thick steel plates are mainly used in shipbuilding, boilers, bridges and high-pressure vessel shells

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.

In chemical processing, the alloy is used for components including heat exchangers, reaction vessels, evaporators and transfer piping.

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.

Forgings are made by forcing materials into customized shapes either by the force of a falling ram upon an anvil or by a die press enclosing a piece of metal and squeeze-forming the part. Forging is a manufacturing process involving the shaping of metal using localized compressive forces.
