Malleable Iron Forged High Pressure Elbow Socket Welding Threaded

STAINLESS STEEL HIGH PRESSURE FITTINGS are used for high pressure system application. The dimension specification is according to ASME B16.11. The ASME B16.11 standard covers ratings, dimensions, tolerances, marking and material requirements for forged fittings, both socket-welding and threaded. Threaded fittings are available in pressure ratings Class 2000, 3000, and 6000; Socket welding fittings are available in pressure ratings Class 3000, 6000, and 9000. Generally, both fittings are available in sizes (NPS) from 1/8″ through 4″. ASME B16.11 socket-welding fittings can be furnished in product forms of 90° elbow, 45° elbow, cross, tee, coupling, half coupling, boss, cap, and couplet; while ASME B16.11 threaded fittings can be furnished in product forms of 90° elbow, 45° elbow, cross, tee, street elbow, coupling, boss, cap, couplet, plug and bushing.

ASME B16.11 forged fittings can be made of materials consisting of forgings, bar, seamless pipe, or seamless tubular products. These materials shall conform to the requirements for the WP seamless construction materials of ASTM specifications A234, A403, A420, A815, or B366, or ASTM forging specifications A105, A182, A350, B462, or B564. Tees, elbows, and crosses shall not be machined directly from bar stock. Both threaded and socket-welding fittings of ASME B16.11 are made in small sizes and have high pressure-temperature ratings. They are used primarily for high-pressure steam.

Standards ASTM A351/A351M-18e1; JIS B2308;
Grade ALL STAINLESS STEEL GRADE

ASTM A351/A351M-18e1 is a standard specification for castings, austenitic, for pressure-containing parts. This standard covers austenitic steel castings that are intended for use at temperatures up to 800°F (427°C) in pressure-containing parts, such as valves, flanges, fittings, and other similar parts.
The castings covered by this specification are classified into four grades, designated as Grade CF3, Grade CF3M, Grade CF8, and Grade CF8M. These grades are differentiated by their chemical composition, mechanical properties, and other characteristics.

Benefits of Stainless Steel Casting Screw Fittings

1. Stainless steel casting combines good corrosion resistance and high strength, which allows the reduction in wall thickness and weight of pipe fittings. Besides, it can withstand very high flow rates, making it capable to withstand long-term exposure to the elements in almost any environment.
2. Cast stainless steel pipe fittings can be used in all types of water, including drinking water in public supply. They have an excellent resistance to the full range of potable waters, including various chloride levels. At the end of its useful life, cast stainless steel is fully recyclable and retains a higher residual scrap value than ordinary cast steel.
3. Stainless steel casting of pipe fittings requires low maintenance and does not need an additional coating, in both indoor and outdoor applications. The expected lifetime of a stainless steel pipe fitting is more than 50 years, reducing system down time, replacement and maintenance costs over the life of the installation.
4. Last but not the least, stainless steel casting is afforable to produce any type of pipe fittings, and it can produce pipe fittings in both high and small volumes.
