Sarplast Qatar offers several types of joining solutions. The most used type of joint is the Bell and Spigot which offers several advantages over the other methods. This joint is one of the main characteristics of the dual helix filament winding process. The bell is obtained during pipe production and is an integral part of the pipe itself. The spigot is machined on the other end and is part of the pipe too.
The main advantages of this type of joint are:
Other types of joints offered by Sarplast Qatar are:
Mechanical Coupling joint
Mechanically coupled joints typically seal on the OD of plain end pipes through the use of sealing gaskets.
Butt and Strap joint
This permanent joint provides continuity in both hoop and axial directions and consists of impregnated glass, mats and tissues laminated according to specified width and thickness. The laminated joint requires special designs, trained and skilled personnel and controlled conditions during the lamination operation.
This is a restrained joint system which is recommended for complex installation comprising accessories, bends, reducers etc. and is designed to sustain high pressure applications. The integral socket and spigot end with matching tapers are joined with a two-component epoxy adhesive glue. In this joint system, no thrust blocks are required since it resists longitudinal forces. It is a rigid joint, as it will not allow any angular deflection.
GRP flanges are available to meet drilling standards according to ANSI, DIN, BS, UNI, etc. Fixed flanges and stub end with steel loose flanges are available.
