Flanges
Flanges 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.
ASTM A/SA105 – ANSI/ASME B16.5 & B16.47
| Size Range | 1/2″ – 48″ |
| Designs | Weld Neck (Incl. Series A&B), Slip On, Blind, Orifice Set, Lap Joint, Socket Weld, Threaded |

| Classes | 125/150/300/400/600/900/1500/2500 |
| Faces | Raised Face, Flat Face, Ring Type Joint |
Larger sizes are available on request.
API Flanges available on request.
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
• Dimensional: ANSI B16.5, B16.1, and MSS SP-44
Buttweld 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.
ASTM A/SA234 WPB – ANSI/ASME B16.9
| Size Range | 1/2″ – 48″ |
| SChedules | STD, XH, 10, 20, 30, 40, 60, 80, 100, 120, 160, XXH |

| Sources | Domestic, Western European/Asian Approved, Generic, Import, China |
Larger sizes available on request.
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.
• Dimensional: ANSI B16.9, B16.11, B16.25, B16.28, and MSS SP-25, MSS SP-48 and MSS SP-75 (for higher yield fittings), WPH-Y42 through WPH-Y70+
Forged Steel Fittings
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.
