Branch Connection fittings

XINTAI pipeline is a leading manufacturer of branch fitting, buttweld pipe olets, socket weld and threaded pipe olets in all material grades and wall thicknesses and in compliance with international standard MSS-SP-97. Our production range includes pipe olets such as weldolet, sockolet, threadolet, laterolet, elbolet, nipolets and sweepolets. We can also manufacture and supply forged flanged outlet fitting in Class 150 to Class 2500 flange ratings. Lateral and elbow olets can be supplied in butt-weld, socket-weld, and threaded end connections. Weld pipe olet or Weldolet is one of the most commonly used branch connection fitting. It is widely considered a buttweld fitting, as it is welded onto the outlet of the pipe. A welding outlet helps in minimizing the stress concentrations and provides integral reinforcement without the need for reinforcing the weld.

Branch Connection fittings (also known as O’lets) are fittings which provide an outlet from a larger pipe to a smaller one (or one of the same size). The main pipe onto which the branch connection is welded is usually called the Run or Header size. The pipe to which the branch connection provides a channel is usually called the Branch or Outlet size. Branch connections are in all sizes, types, bores, and classes, in a wide range of stainless steel, chrome-moly, and other alloys.

Today, XINTAI pipeline Branch Connections offer complete run pipe reinforcement while avoiding cracks, fillet welds, and sharp re-entrant corner reinforcement tapering at the sides, thus preventing abrupt changes in thickness where the fitting joins the header pipe.

XINTAI pipeline fittings meeting the 100% reinforcement requirement of applicable piping codes i.e. ASME B31.1, B31.3, B31.4 and B31.8. They also meet the 2001 edition of MSS-SP-97 Standard- “Integrally Reinforced Forged Branch Outlet Fittings”
