The P2 and P12 steel pipes of A335 should be made by the coarse grain melting method. Steel should meet chemical composition, tensile properties and hardness requirements.

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.

In order to improve the thermal efficiency of the reheat steam pipeline of the power plant, the reheat temperature can be designed to be 621¡ãC, that is, the supercritical temperature. The United States first developed ASTM A335 P92 alloy steel in the late 1980s to meet the heat resistance requirements of this high temperature power plant. Alloy Steel P92 is an improved version of ASTM A335 P91 alloy with deliberate additions of tungsten, vanadium, niobium, reduced molybdenum content to fine-tune the ferrite/austenite ratio, and carefully controlled boron and nitrogen content.

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.

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.

ASTM A335 seamless steel pipe is commonly referred to as chrome molybdenum pipe with chemical elements molybdenum and chromium. Molybdenum can improve steel properties such as strength, elastic limit, wear resistance, impact resistance and hardenability.

Flanges are usually welded or threaded. Flange joints are made by bolting two flanges together with a gasket between them to provide a seal.

A335 P91 material, we use ASTM A335 Gr P91 Welded Pipe
Heat treatment method to standardize the strength of the material. 9% chromium and 1% molybdenum make the pipe strong and corrosion resistant. The material is resistant to wear and high temperature creep. ASTM A335 P91 pipe does not deteriorate, reduces thickness, and has higher creep strength. Pipeline applications are primarily used in power generation, petrochemical, heater and reheat liners, boilers, and petroleum services.

When connecting these parts, put gasket in the middle of two flanges, then tightening the flange screws, so the two will be connected together tightly.

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

The ASTM A194 specification covers carbon, alloy and stainless steel bolts for high pressure and/or high temperature service.

Alloy pipe is a higher percentage of tubular alloying elements such as molybdenum (Mo), chromium (Cr), nickel, etc. than standard carbon steel pipe. In fact, ASTM A335 covers “low alloy” steel pipes, that is, having less than 5% total alloying elements. The addition of higher percentages of alloying elements such as nickel and chromium converts the steel into higher alloys such as stainless steel, duplex stainless steel, up to superalloyed materials such as Inconel, Hastelloy, Monel, etc.
