Alloy steels are used in boiler construction because they are inexpensive, readily available, easy to form and weld into desired shapes, and, in a wide range, have sufficient resistance to oxidation and corrosion to provide many industries with years of satisfaction service. Alloy steels are used in a range of demanding applications in the aerospace and power (nuclear) industries. Alloy steels are also found in applications where their response to magnetism is important, such as in transformers and electric motors.

These ASTM A182 Grade F5 Flanges gives extraordinary erosion resistance in, for instance, caustic and acidic applications which includes sulphuric and higher chloride environments. A182 Gr F5 Threaded Flanges are mostly used in utility services such as air and water. It is similar to the Slip-On flange, but the bore is threaded. Its greatest advantage is that it can be assembled without welding, explaining its use in low pressure services at ordinary atmospheric temperatures, and in highly explosive areas where welding create a hazard.

The A335 P91 chrome tube composition makes these high mechanical properties possible for the material. P91 steel pipe materials can be normalized and tempered during the production process, and can also be quenched and tempered. These methods increase the strength of the material. Additionally, these pipes are drawn and seamless.

All chrome molybdenum steel sheets are sedated and heat treated in accordance with ASTM A387, which also specifies minimum and maximum levels of the following elements in steel: Chemicals of Carbon, Manganese, Phosphorus, Sulfur, Silicon, Chromium, Molybdenum, Nickel, Vanadium requirements, columbium, boron, nitrogen, aluminum, titanium and zirconium. A387 boards must undergo product, chemical and tensile testing (documented in the MTC or material test certificate) – must meet specific requirements for tensile strength, yield strength and elongation.

ASTM A194 Class 2h bolts are carbon base steel heavy duty hex nuts. Sa194-2h material is a common high strength nut. This specification ASTM A194 Class 2h washers are typically used in conjunction with the following fastener standards – A193 Class B7, A325, A490.

Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

A flange can be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.

The Alloy Steel Weld Neck Flange has a welded neck onto it that holds larger pipes in place for easy welding and installation.

Alloy steel sounds like: steel that contains a specific amount of alloying elements. Generally, alloying elements make steel stronger and more resistant to shock or stress. While the most common alloying elements include nickel, chromium, molybdenum, manganese, silicon and copper, many other alloying elements are also used in the production of steel.

A193 B7 Cadmium Plated stud bolts are made of alloy steel for high temperature environments. ASTM standards cover alloy steel and stainless steel bolting materials; this specification covers fasteners for pressure vessels, valves, flanges, and fittings.

ASME SA335 grade p11 tubing contains trace amounts of carbon, sulfur, phosphorus, silicon and manganese. For example, the addition of chromium is known to improve the tensile strength, yield strength, fatigue resistance, wear resistance, and hardness properties of the alloy. The addition of these properties is ideal for preventing oxidation in high temperature applications.

ASTM A182 Gr F9 flanges are typically designed for applications with high temperature requirements. Alloys used to produce flanges according to this specification include wrought or rolled alloys and several stainless steel grades.

Alloy 20 (Alloy 20) is an iron-based austenitic alloy developed to resist sulfuric acid corrosion. It has excellent resistance to sulfuric acid corrosion; it has strong resistance to phosphoric acid, nitric acid and chloride environments, chloride stress corrosion, pitting corrosion and crack corrosion. Therefore, alloy 20 has the name of anti-corrosion alloy; it has a wide range of applications: such as: chemical, food, medicine, power production and plastics industries will use it. For resistance to pitting corrosion and chloride corrosion, stress corrosion cracking problems, etc., alloy 20 is often used.

Forming operations such as bending and flanging, as well as fusion welding, are well suited for ASTM A335 p11 alloy steel pipe. The specified tests for alloy steel seamless pipes include flattening test, bending test, hardness test and longitudinal or transverse tensile test.

HT PIPE is a leading manufacturer of the ASTM A182 Low Alloy Steel flanges as well as the other types of alloys. The ASTM A 182 specification specifies flanges for high pressure services.

Alloy steels are used in a range of demanding applications in the aerospace and power (nuclear) industries. Adding other elements gives alloy steel extra strength.

These are available in different types such as Slip On Flanges., Blind Flanges, Weld Neck Flanges, Socket Weld Flanges, Orifice Flanges, Spectacle Blind Flanges, Screwed / Threaded Flanges, Reducing Flanges, and Ring Type Joint Flanges (RTJ).

Low alloy steel ASTM A182 F11 flanges typically have a total alloy content of 1.5% – 5%. Its common alloying elements are manganese, chromium, silicon, nickel, molybdenum and vanadium. It may contain up to four or five different quantities of these alloys. At the same time, the increased strength of the alloy steel F11 flange may require higher forming pressures. Annealing of SA 182 Gr F11 steel flanges is accomplished by water quenching by thorough immersion at 1725¡ãF – 1850¡ãF (941¡ãC – 1010¡ãC) and can only be hardened by cold work.

The thickness and the inner diameter of the flange will be as per the size of the pipe for which this welding neck flange is being made.
