Product Description

ASTM A182 F316 / 316L Stainless Steel Forged High Pressure Pipe Fittings Socket Welded

This forged stainless steel 316/316L fitting is a female socket weld union fitting used to connect and extend pipes. Socket weld union fittings have an internal concave on the inside diameter, which allows for a smooth inside wall of the pipe and a smoother flow of fluid between pipes. The fittings meet ASTM A182, ASME SA182 and ANSI B16.11 standards and are used in different industries to connect, terminate, control and change the direction of piping. When purchasing fittings, consider their use as this will affect the material type size and required durability.

Application：

oil & gas industry, chemical industry, electric power,boilerand heat exchanger,machinery,metallurgy,sanitary construction etc.

Advantages:

Resistance to high and low temperatures – allowing stainless to serve both as furnace and cryogenic components
Strength and durability – resistance not only to rusting but to chemical attack
Long-lasting functionality with a low lifecycle cost – steels that survive far longer in hostile environments in critical use applications
A glossy and aesthetic appearance – many alloys in the group are used where a desirable surface finish must be achieved and sustained

Socket weld forged fittings may be considered more permanent than threaded forged fittings. Welded joints are considered more relaiable if the welding process is performed correctly, providing a stronger joint attachment. The drawback of fittings of this type is the time and labor for installation. Typical applications for socket weld forged fittings include steam and other gases, toxic fluids and acids, and explosive liquids and gases where highest connection strength and leak prevention are critical.
