ASTM A182 F316 Stainless Steel Socketweld Fittings With Excellent Welding & Forming

Looking for the best grade of fittings? If yes, then ASTM A182 F316 fittings are the right choice for you. These fittings are known for their tensile strength and corrosion resistance. ASTM A182 F316 is a stainless steel grade that is more versatile and provides optimum support and strength for fittings. Yuhong is a leading manufacturer and supply of these accessories all over the world. These accessories are made of the highest quality raw materials and can withstand different temperatures. The steel used to manufacture these fittings allows for excellent welding and forming.

The ASTM A182 F316 specification covers forged or rolled alloy and stainless steel pipe flanges, forged fittings, valves and parts for high temperature service. After hot working, forgings should be cooled to a specific temperature before heat treatment, which should be carried out according to certain requirements such as heat treatment type, austenitization/solution temperature, cooling medium, and quenching. Materials should meet the required chemical composition of carbon, manganese, phosphorus, silicon, nickel, chromium, molybdenum, columbium, titanium. The material shall meet the mechanical property requirements of the grade ordered, such as tensile strength, yield strength, elongation, Brinell hardness. All grades H and F 63 shall be tested for average grain size.

A socket weld is a pipe connection detail in which the pipe is inserted into a recessed area of ​​a valve, fitting or flange. Compared to butt weld fittings, socket weld fittings are primarily used for Small Bore Piping; typically for pipes with a nominal diameter of NPS 2 or less.

To connect pipes to valves and fittings or other parts of the pipe, angle seal welds can be used. Socket welded joint construction is an excellent choice as long as the benefits of high leakage integrity and structural strength are important design considerations.

Fatigue resistance is lower than butt weld construction due to the use of fillet welds and abrupt mating geometry, but still better than most mechanical joining methods.

SW fittings are a family of high pressure fittings used in a variety of industrial processes.

Advantage
Pipes do not need to be chamfered in preparation for welding.
Alignment does not require temporary spot welding, as in principle the fitting ensures correct alignment.
Weld metal must not penetrate the pipe hole.
They can be used in place of threaded fittings, so there is much less risk of leaks.
Radiography of fillet welds is not practical; therefore, proper assembly and welding are critical. Fillet welds can be inspected by surface inspection, magnetic particle (MP) or liquid penetrant (PT) inspection methods.
Construction costs are lower than butt-welded joints due to the lack of strict assembly requirements and the elimination of special machining for butt-weld end preparation.

ASTM A182 F316 Forged Socket Weld Fittings are a low carbon version of 316 and are not affected by sensitization (grain boundary carbide precipitation). Therefore, it is widely used for heavy-duty welded parts (about 6mm and more). There is usually no discernible price difference between 316 and 316L stainless steel.

ASTM A182 F316 Forged Socket Weld Fittings are the standard molybdenum grade, second only to 304 in importance in austenitic stainless steels.

Compared to 304, molybdenum imparts better overall corrosion resistance to 316, especially higher resistance to pitting and crevice corrosion in chloride environments.

The austenitic structure also gives these grades excellent toughness, even at low temperatures.

Compared to chromium-nickel austenitic stainless steels, 316L stainless steel has higher creep, rupture stress and tensile strength at elevated temperatures.
