Flanges & Fittings
Product Families
Weld-Neck, Slip-On & Blind Flanges
The core ASME B16.5 flange types — weld-neck for high-stress butt-welded joints, slip-on for easier alignment, and blind for sealing off a line or vessel opening.
API 6A Flanges
Flanges built to API Spec 6A for wellhead and Christmas-tree equipment, rated for high-pressure, high-temperature production service up to 60,000 PSI.
Large-Diameter (ASME B16.47) Flanges
Series A and B flanges to ASME B16.47 for large-bore pipeline and process piping above the size range of B16.5.
Butt-Weld Pipe Fittings
Elbows, tees, reducers, and caps welded directly into the run to change direction, branch, or resize a line without a bolted joint.
Flange Adapters & Dismantling Joints
Connectors and expansion joints that mate dissimilar flanges, absorb thermal movement, and allow valves or spools to be removed without disturbing the line.
Bull Plugs & Threaded Fittings
Threaded terminations and small-bore fittings, including bull plugs that cap off a line and DIN/threaded tube fittings for instrument and utility connections.
Alloy, Duplex & Clad Fittings
Flanges and fittings in alloy steel, duplex steel, copper-nickel, or with a corrosion-resistant clad layer for sour, marine, and severe-service media.
API 20B Forgings
Open-die and shaped forgings produced to API Spec 20B as the raw stock for flanges and fittings used in critical pressure-containing equipment.
Flange Bolting & Fasteners
Stud bolts, nuts, and fasteners to API 20E/20F that clamp flange pairs together and develop the gasket seating load.
Gaskets, Ring Joints & Insulation Kits
Flange gaskets, API ring gaskets (RTJ), and insulation kits that seal the joint and electrically isolate flanges for cathodic-protection and corrosion control.
