Flanges, Rated Pressure : 150#, 300#

We are offering Flanges.
A flange is a forged or cast ring of steel designed to connect sections of pipe or join pipe to a pressure Vessel, pump or any other integral flanges assembly.
Flanges are joined to each other by bolting and joined to the piping system by welding or threading.
The basic types of flanges are; Slip on, Blind, Weld Neck, Threaded, Socket Weld, Lap Joint and Orifice.
Flanges are designed to the following pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.
The most common facings machined on flanges are:
(a) Raised face, 116 inch for 150lb and 300lb, ¼ inch for 400lb and heavier.
(b) Flat face, for 150lb and 300lb only, other may be flat face on request.
(c) Ring type joint, may be applied to all pressure ratings.
TYPES & APPLICATIONS
Slip-On Flange
The flange is slipped over the pipe and then welded both inside and outside to provide sufficient Strength and prevent leakage. This flange is used in preference to weld necks by many users because of its lower cost and the fact that less accuracy is required when cutting pipe to length.
Blind Flanges
This is a flange without a bore and is used to shut off a piping system or vessel opening. It also permits Easy access to vessels or piping systems for inspection purposes. Blind flange can be supplied with or without hubs at the manufacturers option.
Weld-Neck flange
This is designed to be joined to a piping system by buttwelding. It is relatively expensive because of Its long neck, but is preferred for high stress applications. The neck, or hub transmits stresses to the the base of the hub to the wall thickness at the butt weld, provide important reinforcement of the flange.
Socket Weld
This is similar to a slip-on flange in outline, but the bore is counter-bored to accept pipe. The diameter of the remaining bore is the same as the inside diameter of the pipe. The flange is attached to the pipe by a fillet weld around the hub of the flange.
