Flange Types Supplied by Hotline Steel
Slip-On Flanges
Slip-on flanges have a low-hub design – the pipe slips into the flange before welding, and the flange is welded both inside and outside for strength and to prevent leakage. The bore is sized slightly larger than the pipe’s outside diameter to allow this fit.
Welding Neck Flanges
Welding neck flanges use a “high hub” design that transfers stress into the pipe, reducing stress concentration at the base of the flange. This makes them a common choice for higher-pressure or higher-stress piping systems.
Threaded Flanges
Threaded flanges are similar to slip-on flanges but have a threaded bore, allowing installation without welding. This makes them useful for low-pressure service at ordinary temperatures, and in areas where welding presents a safety risk.
Blind Flanges
Blind flanges have no bore and are used to close off the end of a piping system or a pressure vessel opening. Because they can be removed, they also allow a sealed line to be reopened later for inspection or modification. Hotline Steel Trading L.L.C supplies blind flanges to DIN 2632/33, BS 4504 (PN 10/16/25) and ANSI B16.5/ASTM A105 (Class 150 & 300) specifications, from 1″ to 24″.
Stainless Steel Flanges in UAE
Hotline Steel Trading L.L.C supplies stainless steel flanges to ASTM A182, covering grades F304(L,H), F316(L,H), 316TI and F321, in sizes from 1″ to 24″. These grades are available across the same flange types listed above slip-on, welding neck, threaded and blind for projects specifying stainless steel rather than carbon steel construction.
