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.

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.

Weld Neck Flange is expensive because of its long neck and cost of people for contact WN flange with pipeline or fitting but is preferred for high-stress applications. The necks, or hubs, transmits stresses to the pipeline.

For A335, chromium is a key ingredient used to make stainless steel. If the chromium content is above 12%, it can be classified as stainless steel. Even at high temperatures, the antioxidant potential of chromium is irreplaceable. Better hardness, tensile strength and yield strength at standard temperature. Due to the material’s composition, it is ideal for use in power plants, refineries, petrochemical plants and other oilfield services involving high temperature and high pressure transportation.

ASTM A320 L7 washers are specially engineered for LOW temperature performance. These fasteners are commonly used for valves, flanges, fittings, and pressure vessels.

ASTM A193 Grade B7 specification covers requirements for high tensile alloy steel bolting material for use in high temperature or high-pressure service and other special purpose applications.

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

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.

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 Alloy Steel Pipe Fittings are very easy to install and have a low hub due to the pipe going into the fitting before welding.

A182 F5 material is an excellent alloy that is hardened only by cold working. It is often used in nuclear energy, medical equipment, chemical energy, etc. These ASTM A182 Grade F5 Flanges gives extraordinary erosion resistance in, for instance, caustic and acidic applications which includes sulphuric and higher chloride environments.

ASTM A335 Pipe (ASME S/A335, Chorme-Moly) is a seamless ferritic alloy steel pipe for high temperature service. Pipe ordered in accordance with this specification shall be suitable for bending, vanstoning and similar forming operations, and fusion welding. Sometimes referred to as “P grade”, lilac molybdenum tubing is popular in P grades P5, P9, P11, P22 and P91. The P11, P22 and P91 grades are most commonly used in the power industry and petrochemical plants, while the P5 and P9 grades are often used in oil refineries.

High alloy steel is defined by a high percentage of alloying elements.

The composition of the chrome-molybdenum alloy steel pipe in A335 makes it ideal for power plants, refineries, petrochemical plants and oilfield services that transport fluids and gases at extremely high temperatures and pressures.

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.

Its greatest advantage is that it can be assembled without welding, which explains its use in low-pressure service at ordinary atmospheric temperatures and in highly explosive areas where welding creates a hazard.

A182-F11 has good process performance and welding performance, and high durable strength at 500 ~ 550¡æ.

The term “bolting material” as used in this specification covers, rolled, forged or strain hardened bars, bolts, washers, screws, studs and stud bolts.

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.

The high chromium content gives these forgings fittings very good resistance to moisture erosion, which also contributes to their high temperature strength and resistance to scaling at high temperatures.

ASTM A335 P91 Seamless Pipe is one of the seamless pipes that standardize A335 in various industries. ASME SA 335 Grade P91 Alloy Steel Pipe is made of chrome molybdenum alloy. These pipes contain 1% molybdenum, 9% chromium and nickel, manganese, silicon and carbon. ASTM A335 P91 pipe has very high tensile strength, yield strength, impact cracking resistance, corrosion cracking resistance and oxidation resistance.

ASTM A182 Alloy Steel F22 Fittings are available in a variety of shapes, sizes and dimensions according to the needs or requirements of the application or to customer supplied specifications.

The low alloy steel pipe flanges also tend to provide better mechanical properties as opposed to many conventional, standard mild or carbon steels.

Alloy steel is a steel alloyed by adding a variety of elements with a total amount between 1.0% and 50% in order to improve its mechanical properties. Alloy steels are divided into two categories: low alloy steels and high alloy steels. The distinction between the two is debatable. Smith and Hashemi defined the difference as 4.0%, while Degarmo et al. defined the difference as 8.0%. Most commonly, the phrase “alloy steel” refers to low alloy steel.

This is used in fabrication of tubes, boilers and super heaters. On many other applications, this is used and is available in various other sizes and shapes.
