The ASTM A/ASME SA 335 specification covers seamless ferritic alloy steel pipes for high temperature service. The pipe is mainly used for bending, vanstoning and similar forming operations, as well as for fusion welding.

ASTM A193 Grade B7 specification covers the requirements for high strength alloy steel bolting materials for high temperature or high pressure service and other special purpose applications. It is a standard specification that defines typical chemical composition, mechanical properties, hardness requirements, preferential heat treatment, product marking, certification, and other requirements for bolted connections used in pressure vessel service, valves, flanges, and fittings. ASTM A193 defines SI (metric) and inch-pound units.

N04400 is a ductile nickel-copper-based alloy consisting primarily of two-thirds nickel and one-third copper. Alloy N04400 is known for its resistance to a variety of corrosive conditions, including alkalis (or acid-like substances), brine, hydrofluoric acid, and sulfuric acid. Other advantages of using this alloy are toughness and high strength over a wide temperature range; it can also be manipulated to be magnetic if desired.

Alloy A182 flange also has durability and longevity.

The wider range of flanges are being offered like ASTM A182 F9 slip flange, F9 alloy welded steel socket flange, alloy steel F9 orifice flange, A182 F9 threaded and screwed flange etc. Imperative for the uniqueness of Alloy Steel F9 Socket Weld Flanges is the allotropy of iron-that is, its existence in two crystalline structures.

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

Bolts are chrome molybdenum heat treated steel according to ASTM A193 B7m specification for bolts. The primary alloy components of ASTM A193 Grade B7 bolts are chromium and molybdenum. These ASTM A193 B7 Metric Bolts are manufactured by heat quenching and tempering. Heat treating A193 B7 bolt material helps to develop desired mechanical properties such as increased tensile strength of ASTM A193 B7 hex bolts after heat treatment.

Please make sure to contact us for more information on the pipe fitting products such as the ASTM A860 MSS SP 75 WPHY 52 Pipe Fittings and their pricing.

WPHY 52 Fittings are recommended be heat treated by one or more of the following procedures: annealing (stress relieving), normalizing, normalizing and tempering, quenching and tempering.Made utilizing high-grade crude materials, these ASTM A860 WPHY Pipe Fittings are anti-corrosive and strong.

For the F5 flange, the creep strength of the chromium-molybdenum low alloy mainly comes from two sources: the solid solution strengthening of the matrix ferrite by carbon, molybdenum and chromium and the precipitation hardening of the carbides.

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.

Our alloy steel pipes and tubes are packaged and delivered in conspicuous packaging in wooden cases, plywood cartons, boxes, pallets to ensure no damage to any product when exported. Additionally, we offer custom packaging options so that customers can order according to their suitability.

When the carbon content of the a333 gr 6 welded pipe chemistry is lower, the chance of cracking in the welded area is also lower. However, some manufacturers prefer seamless pipes over welded pipes. The reason behind this is that the performance of the a333 gr 6 seamless tube is almost 20% higher than the welded one in high pressure environments.
