Welded Spigot and Socket Joint

Popular in the permanenet 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 strengthens the tightness of the joint.

Flanged Joints

Suitable for temporary or permanent joint. Flange dimension usually to B.S.10 or B.S.4504 welded to one or two end of pipes.

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

Mechanical Coupling

Recommended 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.
