Seamless High Pressure Stainless Steel Pipe Fittings

Seamless High Pressure Stainless Steel Pipe Fittings

Stainless steel pipe fittings require minimal maintenance. Regular inspection and cleaning are recommended to remove any dirt, debris, or corrosion. In corrosive environments, proper material selection and periodic inspection are crucial to ensure the longevity and performance of the fittings.

There are various types of stainless steel pipe fittings available to suit different needs. Some common types include:

Stainless steel pipe fittings are typically made from stainless steel for its corrosion resistance and durability. The most common stainless steel grades used for fittings include 304/304L and 316/316L, which offer excellent resistance to corrosion and high-temperature environments.

Product Information:

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.

Types of End Connections: Socket Welding & Threaded

ASME B16.11 forged fittings may be furnished with socket-welding ends, threaded ends, or a combination of the socket-welding end and threaded ends.

Threaded (THD) Ends

The threaded end connection for joining pipe is generally referred to as screwed connection. With tapered grooves cut into the ends of a run of pipe, screwed fittings and screwed pipe can easily be assembled without welding or other permanent means of attachment. The ASME B16.11 threaded fittings will have threads that are either male or female in accordance with ASME B1.20.1. Male threads are cut into the outside of the fitting, while female threads are cut into the inside of the fitting. As threaded fittings are assembled with threaded pipes, a short length of pipe is drawn into the fitting. This connection is called a thread engagement.

Socket Weld (SW) Ends

When assembling pipe with ASME B16.11 socket welding fitting, the pipe is inserted into the fitting before welding. Inside the socket-weld fitting is a collar that prevents the pipe from being inserted too deeply into the fitting. A short amount of pipe is lost when the socket-weld connections are made. Before the weld is made, the pipe fitter will back the pipe off the collar approximately 1/8″ to allow for heat expansion during the welding procedure. Pipe used for socket-weld connections will be prepared with a plain end. Plain end (PE) means the pipe is cut square, or perpendicular to, the central long axis.
