Flanges

langes are necessary to attach piping sub-assemblies to pressure vessels, valves, pumps or other devices. Flanges are forged or cast rings of steel, designed to join two sections of piping together by bolting. Domestic and import sources.

Sizes:

1/2” to 48″.
Larger sizes are available on request

Pressure Ratings:

150, 175, 300, 400, 600, 900, 1500 and 2500 PSI
API Flanges available on request.

Configurations:

Slip on
Weld Neck
Threaded
Lap Joint
Socket Weld
Blind
Reducing
Orifice Flange Sets (complete)
Tongue and Groove (on request)
Small and Large Male and Female (on request)
Plate Flanges
Raised and Flat, RTJ and other Facings

Specifications governing the properties of carbon steel flanges are:

Physical and Chemical: ASTM A/SA-105, ASTM 694 F-52, F-60, F-65, F-70

Butt Weld Fittings

Piping systems joined by welding offer considerable advantage over other types of systems. A welded system is permanent, leak-proof and requires little or no maintenance. Welding construction uses a minimum of space, enabling it to be nested in corners or fitted against ceilings, walls or equipment. Domestic and import.
Sizes:

1/2” to 48”
Larger sizes available on request.

Wall Thickness:

Standard
Extra Heavy
True and Special Schedules

Configurations:

45°, 90°, and 180° Elbows (Other degrees available on request and POA)
3R Elbows - 45° & 90°, segmentable and non-segmentable.
Straight Tees
Reducing Tees and Elbows
Concentric and Eccentric Reducers
Caps and Stub Ends
Crosses and Laterals

Specifications governing the properties of weld fittings are:

Physical and Chemical: ASTM A/SA234-WPB and WPB-X produced from plate fittings up to 24″ considered to be seamless.
Fittings 26″ and higher are generally constructed from plate and welded such as ASTM A-516

Forged Steel products

Forged steel fittings are machined from solid forgings. The quality of the fittings is critical in that they are designed to withstand higher pressures. Important factors in the design of forged steel fittings are: uniformity of wall, wide bands, sharp threads properly chamfered and unrestricted flow. Domestic and import sources.
