SINTAKOTE® steel pipeline systems can be connected via a wide variety of jointing systems. A wide variety of joints are available from Steel Mains to accommodate project specific needs. Joints for water pipelines will depend upon the specific requirements of the construction and performance of the pipeline.


Further to the information shown on the page below, please refer to the below brochures which outline the various applications that our range of joints are suited to. These data sheets offer various details on the capability of the joint.

Rubber Ring Joints

SINTAJOINT® is a rubber ring joint specifically designed to eliminate the need for any on site field reinstatement after assembly on site. It provides a factory applied coating system that is continuous within the joint, with its interface under the cement lining ensuring a complete envelope coating end to end.


SINTAJOINT is available in pipe sizes from DN 300 to DN 1800. Each joint provides angular deflection up to 3° dependent on diameter. In some special situations where ground strains are expected to be high, e.g., in a mine subsidence area, deep entry SINTAJOINT can be provided to accommodate the greater axial displacements expected.

Sintajoint - Rubber Ring Joint

SINTALOCK® provides all the benefits of SINTAJOINT and when combined with external welding, enables construction of a fully end restrained pipeline without the need for concrete thrust blocks. This is a significant improvement on welded joints as it eliminates the safety issues associated with entry. SINTALOCK is also much faster to install as only external welding is required.
