National Standard Branch Outlet
The national standard branch outlet (weldolet) implements the current national standard GB/T19326-2022 "Forged Branch Outlet Fittings," modified to adopt the MSS SP-97 international specification, and is an integrated reinforced forged branch pipe fitting dedicated to domestic pressure piping. The product is integrally die-forged from round steel forging blanks, manufactured through forging, heat treatment, non-destructive testing, and CNC precision machining, requiring no cutting of the main pipe, and is directly welded to the outer wall of the main pipe to achieve branch extraction, relying on the reinforcing structure built into the body itself to disperse stress at the opening location and reduce the risk of cracking and leakage under high-pressure working conditions. Connection structures cover butt welding, socket welding, threaded, 45° oblique connection, elbow type, extended type, and flanged type, with nominal diameters covering DN6-DN100, and materials covering carbon steel, stainless steel, alloy steel, low-temperature steel, and duplex steel. A full set of national standard factory documentation can be issued, supporting standard stock items and non-standard customization according to drawings, suitable for pipeline branch systems of domestic industrial piping and domestic EPC overseas general contracting projects.

British Standard branch outlet
British Standard branch outlet (BS forged branch outlet, Forged Branch Outlet) is formed by integral hot die forging, and after forging undergoes heat treatment, non-destructive testing, and precision machining. During installation, there is no need to cut the main pipe; it is directly welded to the outer wall of the main pipe to lead out the branch, and relies on the forged body itself to achieve opening reinforcement, avoiding the stress concentration and erosion leakage problems caused by on-site opening reinforcement pads. The product core implements the BS 3799 British petroleum industry forged pipe fittings standard, and new projects in the United Kingdom simultaneously adopt the BS EN 10253 European-British unified pipe fittings specification, with structural design referring to MSS-SP-97. Specifications cover DN6-DN100, pressure ratings 3000LB, 6000LB, 9000LB, and threads use BSPP/BSPT British standard pipe threads. EN10204-3.1/3.2 inspection certificates can be issued, suitable for oil and gas, power stations, chemical engineering, and thermal pipelines, supporting spot supply and non-standard customization according to drawings.
