The flanges can be threaded, ring type joint, lap joint, weld neck or socket welded.

Besides these elements the addition of trace amounts of both Manganese and silicon, other set of common alloying elements, provides the alloy steel threaded flanges with excellent deoxidizing capabilities.

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/ASME A387/SA387 Alloy Steel Gr. 5 CL 1/2 is a chrome molybdenum alloy steel plate primarily used in welded boilers and pressure vessels designed for high temperature service. The Cr content was 5.00%, and the Mo content was 0.5%.

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.)

These ASTM A182 alloy steel F12 flanges are corrosion resistant. ASTM A182 alloy steel F12 flanges also have high dimensional accuracy.

It is almost the same as AISI 4130 chrome-molybdenum alloy steel, but with a slightly higher carbon content. Compared to AISI/ASTM 4130 alloy steel, AISI 4140 steel has a higher carbon content, which provides higher strength and heat treating capability, but also has limited weldability.

ASTM A335 Alloy Steel Seamless Pipe Alloy steel contains significant amounts of elements other than carbon, such as chromium, silicon, nickel, manganese, molybdenum, tungsten, vanadium, and limited amounts of other generally accepted elements such as sulfur, manganese, silicon, and phosphorus . These alloying elements are usually added to increase the hardness, strength and chemical resistance of the final product.

F5 A182 Pipe Flanges tends to have a fairly high electrical conductivity amongst other wrought alloy steels in the same category. It has a comparatively high base cost and high embodied energy. ASTM A182 is the Standard Specification for Forged Stainless Steel Pipe Flanges and Stainless Steel Forged Fittings.

Hot rolled 4140 steel also has good fatigue resistance and impact resistance after heat treatment.

The mechanical properties of the astm a182 f9 loose flange include its high tensile strength, good corrosion resistance, increased hardness and toughness properties.

It helps improve fatigue resistance. Many industries, including paper and pulp, chemical reprocessing, water pipelines, nuclear power plants, heat exchangers and others, use ASME sa182 f12 projects in a variety of applications. Our Premium Alloy Steel F12 Flanges are corrosion free, edge perfect, efficient, lightweight, frictionless work, easy to install, highly conductive and of great quality.

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.

ASTM A335 is the standard specification for seamless ferritic alloy steel pipe for high temperature service. Covers server levels: P1, P2, P5, P5b, P5c, P9, P11, P12, P15, P21, P22, P23, P91, P92, P122, of which P5, P9, P11, P22, P91, P92 are used in practice the most extensive. This specification covers nominal and minimum wall chrome-molybdenum (also known as Cr-Mo or Cr-Moly) alloy steel pipes for high temperature applications. Pipe ordered to this specification shall be suitable for bending, vanstoning and similar forming operations, and fusion welding. ASTM A335 P11, P22, P91 and P92 are commonly used in power plants and the chemical and petrochemical industries, while P9 and P5 are mainly used in oil refineries.

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.

ASTM A182 F11 class 1 Flange is the method of connecting two pipes, pumps and valves. This consists of chromium molybdenum based alloy steel grade.

ASTM A335 P11 is part of ASTM A335, Pipe shall be suitable for bending, flanging, and similar forming operations, as well as fusion welding. The steel shall meet the requirements of chemical composition, tensile properties and hardness. Each pipe shall be hydrostatically tested. In addition, each pipe shall be inspected in accordance with the practice required for non-destructive testing.

ASTM 182 is used for pressure systems, including flanges, fittings, and similar parts that conform to specified dimensions or dimensional standards such as ASME codes.

It exhibits exceptional corrosion resistance in chemical environments containing phosphoric acid, nitric acid, chlorides and sulfuric acid. It also has good mechanical properties at both ambient and elevated temperatures.

The austenitic formation of Alloy Steel F9 Weld Neck Flanges offers outstanding durability, even at cryogenic temp. Those are high tensile strength, anti-corrosive, flexibility, durability, low maintenance, good dimensional accuracy, excellent surface finishes.

A weld neck flange, also called a tapered hub flange or high-hub flange, is a kind of flange that can relocate stress to the pipes, ensuring a decrease in high-stress concentration at the bottom of the flange.

La especificacion ASTM A193 Grado B7 cubre los requisitos para materiales de empernado de acero aleado de alta resistencia para servicio de alta temperatura o alta presion y otras aplicaciones de proposito especial. Es una especificacion estandar que define la composicion quimica tipica, las propiedades mecanicas, los requisitos de dureza, el tratamiento termico preferencial, el marcado del producto, la certificacion y otros requisitos para las conexiones atornilladas utilizadas en el servicio de recipientes a presion, valvulas, bridas y accesorios. ASTM A193 define unidades SI (metricas) y pulgadas-libras.

High alloyed types of steel are favored in the plumbing industry for use in extreme conditions, be it hot or cold, or subjected to rough service. This is because a combination of chemistry and proper heat treatment can result in a strong and flexible pipe that can withstand blows. Alloy pipes are often favored by the oil and gas and power generation industries due to their toughness.
