Alloy steel pipes are common in applications involving automobiles, kitchenware, and industrial equipment. Typically, superalloy steel boiler tubes are used in applications with ambient temperatures exceeding 500¡ãC. For example, hollow and thin-walled alloy steel drill pipes must be able to resist pressure differences that manifest between the inside and the outside of these alloy steel seamless pipes.

ASTM A193 define unidades SI (metricas) y pulgadas-libras.

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.

SA182 F5 Plate Flange can be used in those environments where there is a presence of mild corrosive compounds. It can also be used in non-corrosive applications as well as in erosive applications at the temperature between ranging between -30oC up to +650oC. ASTM A182 Grade F5 Flanges in conditions characterized by increased levels of carbon dioxide (CO2), hydrogen sulphide (H2S), and as well chlorides (Cl). The highlight of A182 F5 Steel Slip On Flanges are Precise plan, Accurate measurements, Resistant to corrosion, Less costs, pitting and crevice resistance.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.

For most applications, INCONEL alloy 718 is specified as: solution annealed and precipitation hardened (precipitation
hardening, age hardening, and precipitation heat treatment are synonymous terms).Good mechanical properties: tensile, fatigue and creep-rupture

Shaped flanges made by die forging or precision (lost wax) casting, depending on the mechanical properties of the flange, die forged flanges have higher strength than cast flanges. Precision profiled flanges manufactured by forging or casting require a model (tool).

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.

ASTM A182 Stainless Steel Flanges are manufactured per ASME B16.5 150#, 300#, 600#, 900#, 1500#, 2500#.

Our Alloy Steel Seamless Pipes (IBR) are made of alloy steel with excellent properties. These were developed for energy-related applications involving oil and gas drilling and are therefore subject to the stress of machine parts. In addition, alloy steel pipes are used in domestic, professional or industrial fields.

The production of ASME SA182 F9 flanges will be done using alloys with lower carbon content. Reducing the carbon content in these alloys reduces the formation of carbide precipitates. This basically means that alloy steel F9 flanges will no longer be susceptible to intergranular corrosion in the heat affected weld zone.

ASTM specifications recommend a minimum Charpy impact value for ASTM A320 L7 Stud Bolts to be 20-ft-lbf @ -150F. The Charpy impact test determines the total amount of energy that is absorbed by a material during fracture, thereby indicating the material¡¯s notch toughness.

They can also be seamless in nature. The nominal diameter of the seamless fittings ranges from ? inches to 24 inches and the welded fittings range from ? inches to 120 inches in diameter.

Alloy steel flanges have corrosion oxidation stress corrosion cracking and crevice corrosion resistance.

Chromium molybdenum is used in power generation and petrochemical industries for its tensile strength, corrosion resistance and high temperature strength.

The flange connection type usually comes with double units, with a gasket and some bolts & nuts to connect each other. (Firstly pipes are welded on the flanges, then valves and other equipment could be installed on flanges.)

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

A182-F11 has high thermal strength (¦Äb¡Ý440MPa) and oxidation resistance at high temperature, and has certain resistance to hydrogen corrosion.

Alloy steel DIN 1.7335 round bars also offer some other outstanding properties such as perfect finish, dimensional stability, light weight, high load-carrying capacity, longer life, fine dimensions and more.

ASTM A335 P11 seamless pipes are used in the production of transmission components in the automotive industry. Tubing is also used in the oil and gas industry because it is stronger, harder and has good properties at high temperatures.
