The olet table is used to open the olet on the main pipe wall; the connection form with the main pipe is welding, and the connection mode with the olet may be butt welding, socket welding or thread; the main pipe and the olet connected by the olet table are vertical or oblique Cross relationship.

The pipe Coupling is used for the connection at the pipe joint of the two pipes; the connection mode of the two pipes to the pipe Coupling is socket welding or thread; the two pipes connected by the pipe Coupling have the same axial direction.

For pipe diameter

  1. Sockolets: refers to the socket welding pipe table for pipe diameter DN15~DN40, see standard MSS-SP-97
  2. Weldolet: refers to the butt welding pipe table for pipe diameter DN50 or above, see standard MSS-SP-97
  3. Threadolet: Threaded pipe stand for pipe diameter DN15~DN40, see standard MSS-SP-97

Full coupling, socket welding, for pipe diameter DN15~DN40, see standard ASME B16.11, GB/T 14383-2008

Half coupling, socket welding, for pipe diameters DN15~DN40, see standard ASME B16.11, GB/T 14383-2008

The olet station is widely used in foreign countries in recent years. The reinforcing pipe fittings used for olet connection replace the traditionally used reducer tee, reinforcing plate and reinforced pipe section, etc., which are safe and reliable, reduce the cost; simple construction Improve the medium flow channel; serialization standardization, convenient design and other outstanding advantages, especially in high pressure, high temperature, large diameter, thick wall pipe.

Stub end

Stub end

Stub Ends are fittings used in place of welded flanges where rotating back up flanges are desired.

  • They are also called Lap Joints and Vanstone Flared Laps.
  • Lap Joint Flanges - available in a range of sizes to pair with stub end fittings for easy dismantling
  • Stainless stub end such as Stainless Steel ASTM A403, 304L, 316L, 317
  • Carbon steel Stub end is tested and verified for durability, accuracy and precision
  • Pipe collars are made from plates, with dimensions and tolerances in accordance with EN 1092-1 (Din 2642) or for lap joint flanges according to Asme B16.5.

Common type of Butt weld pipe fittings

A common example using welded pipe fitting is a pipe reduced by concentric reducer, welded to a weld neck flange and connected to an equipment. Figure below represent complete collection of butt welded pipe fitting

Fitting specification, Standard and identification

There are different varieties of pipe fittings made of various materials and available in various shapes and sizes.
