Whether manufactured to ANSI, ASME or custom standards, flanges are critical to manufacturing, utility and industrial applications around the world.

Alloy steel pipes are used for high temperature and very low temperature service (low temperature) in the energy industry, or for very high pressure applications. ASTM A335 Alloy Steel Pipe is suitable for ASTM A234 WPx Series Butt Weld Fittings (WP5, WP9, WP91) and A182 Fx Forged Fittings and Flanges (A182 F5, F9, F11, F22, F91). All of these materials have similar chemical and mechanical properties and can be joined or welded.

A335 pipe is highly resistant to rupture at high temperature and pressure. Chromium molybdenum tubes with resistance to hydrogen cracking and sulfide stress corrosion cracking are superior to carbon tubes.

Pipes made of SA335 p11 material are commonly used in a variety of applications in different plants and processes around the world. For example, applications for SA335 grade p11 tubing include power plants, petrochemical plants, refineries, hydrocrackers, cokers, reheat pipelines, distillation, oilfield services, high temperature and ultra-high temperature pipelines, and more.

ASTM A182 is the Standard Specification for Forged or Rolled Alloy Steel Pipe ASTM A182 F11 Flanges, Forged Fittings, and Valves and Parts. These alloy steel A182 grade F11 WNRF flanges are designed for high temperature applications.

Grade B7 is a heat-treated chromium-molybdenum low-alloy steel with minimum tensile strength requirement of 125 ksi (860 Mpa), yield 105 ksi (720 Mpa), and maximum hardness of 35HRC.

While chromium is an important alloying agent in a335 P91 piping, it is known to prevent corrosion and has a high resistance to oxidation at high temperatures. Since these pipes are surface treated or coated, they are also protected against corrosion. Surface coating can be accomplished by various techniques such as passivation, phosphating, oil immersion, varnishing and shot peening.

B7 threaded studs and short head bolts are readily available in the market. B7 grade bolts are often used for pipe flange connections. These bolts are usually sold in a normal bare metal finish, but are usually hot-dip galvanized, galvanized, Xylan coated, PTFE coated, or otherwise treated with a corrosion resistant coating.

Alloy pipe is defined according to the material used in production (ie material), as the name suggests, it is made of alloy pipe; seamless pipe is defined according to the production process (seamless), which is different from seamless pipe is seamless pipe, Including straight seam welded pipe and spiral pipe.

ASTM A193 Grade B8 Grade 1 Bolts and Studs Made of AISI 304 Stainless Steel. Type 304 is the most commonly used stainless steel grade in the fastener industry.

Inconel600 is suitable for welding with the same material or other metals by any traditional welding process, such as tungsten electrode inert gas welding, plasma arc welding, manual sub-arc welding, metal inert gas shielded welding, molten arc inert gas shielded welding, and pulsed arc welding. Welding is the preferred solution. When using manual arc welding, it is recommended to use a shielding gas mixed with various components (Ar+He+H2+CO2).
Welding of Incoloy 825 must be carried out in the annealed condition and cleaned with a stainless steel wire brush to remove stains, dust and various markings. When welding the root of the weld, extreme care must be taken (Argon 99.99) to obtain the best quality of the root weld so that the weld does not produce oxides after the root has been welded. Color from the weld heat-affected zone should be removed with a stainless steel brush while the weld area is not cool.

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.

Alloy steel is divided into two categories: high-alloy steel and low-alloy steel. Low alloy steel flanges, on the other hand, contain about 0.05 ¨C 0.25% carbon and up to 2.0% manganese.

Our Alloy Steel ASTM A182 F5 Weld-neck Flanges are supplied to aid industrial, high pressure services like condensers, boilers, evaporators, heat exchangers, etc. Alloy steel F5 A182 flanges is also available in the form of lap joint flanges, plate flanges, threaded flanges, reducing flanges and many more. These flanges are widely used in power generation industry, gas processing industry, pharmaceutical industry, heat exchangers industry, sea water equipment industry, oil drilling companies and many more.

The Alloy Steel F12 Flanges are also very strong due to the annealing of them. Grade F12 Flanges can be supplied in either normalized or quenched and tempered conditions. Alloy Steel F12 Weld Neck Flanges is appropriate to various applications where its different remarkable characteristics are sought-after but a brushed/polished finish is not necessary.

The composition of A335 P91 material contains carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, vanadium, nitrogen, nickel, aluminum, niobium, titanium and zirconium. There are two kinds of seamless pipes and welded pipes. Seamless pipe is drawn from a single raw material billet, while ASTM A335 Gr P91 Welded Pipe is welded from strip or sheet. Welding can be helical or longitudinal from one end to the other to produce the tube. The minimum yield strength of the pipe is 415MPa and the minimum tensile strength is 585MPa.

Despite adding these elements, low alloy steel flanges aren’t necessarily difficult to weld. The key to achieve a successful performance of the welding operation is by knowing exactly what type of low-alloy steel you have.

Fasteners made from this austenitic stainless steel require carbide solution treatment of the bar to be threaded, or carbide solution treatment after the head operation of bolts with forged heads.

B7 and B7M shall be heat treated by quenching in a liquid medium and tempering. For B7M fasteners, the final heat treatment, which may be the tempering operation if conducted at 1150 ¡ãF [620 ¡ãC] minimum, shall be done after all machining and forming operations, including thread rolling and any type of cutting.

In applications where higher working pressures are a prerequisite, the use of seamless pipes is justified. Although stronger than welded pipe, the cost is much higher. In addition, in welded products, there is a greater risk of intergranular corrosion in the heat-affected weld zone. The obvious difference between alloy steel welded pipe and seamless product is the transverse seam along the length of the pipe
