TYPES OF JOINTS FOR USE WITH PIPE

Welded Collar Sleeve Joint
Short Sleeve Steel Split Collar of the same thickness to the adjoining pipes. Suitable for joining plain end pipes and specials as it can be welded either internally or externally.

The collar is inderted and aligned between the two adjoining pipes end, making it easy to hold pipes for welding process.

Welded Spigot and Socket Joint
Popular in the permanent pipelines joining where welders are able to perform task with normal welding process. This design needs only a single circumferences weld, reducing workmanship cost and time, without affecting the quality of joint.

Socket sleeves are sized to ensure the spigot enter socket sleeve freely for good fit when inserted fully. The penetration enhances and strentehns the tightness of the joint.

Flanged Joints
Suitable for temporary or permanent joint. Flange dimensions usually to B>S.10 or B.S.4504 welded to one two end pipes.

This design only requires simple assembly using bolts, nuts, washers and joint rinfs in joining up two pipes, which could be performed at the site of installations.

Mechanical Coupling
Recomended for pipelines having small dimensions for lining. This coupling joins two plain end pipe of same outer diameter after being laid at site.

For permanent and temporary line joins, it also relieves the contraction and expansion forces.
