Product Description

Products Instruction:

Joint Type – Grooved fittings use a mechanical joint that relies on roll grooves and a flexible gasket to seal the joint. Rigid fittings use threaded joints that are sealed with tape or pipe dope.

Installation – Grooved fittings are faster to install than rigid joints since they don’t require threading. The grooved pipe is simply inserted into the fitting and bolted in place.

Flexibility – Grooved joints allow for some angular flexibility, alignment changes, and minor movement between pipes. Rigid joints are static and do not permit any movement between pieces.

Products Advantages:

Roll grooved pipe fittings refer to a type of pipe fitting system where a groove is created on the pipe end using a roll grooving machine. This groove is then used to connect the pipe to a grooved coupling, creating a secure and leak-tight joint.

Roll grooved pipe fittings offer several advantages. First, they provide a reliable and efficient method of connecting pipes. The grooved coupling, when combined with the groove on the pipe, creates a strong and leak-resistant joint. This eliminates the need for welding or threading, saving time and labor during installation.

Another benefit of roll grooved pipe fittings is their flexibility. The grooved joints allow for slight movement and expansion/contraction of the pipes, accommodating thermal changes and reducing stress on the system. This flexibility is particularly beneficial in applications where pipes are subject to temperature variations or vibration.

Diffrerences Between Flexible Grooved Coupling And Rigid Grooved Coupling:

The key distinguishing features between rigid and flexible grooved couplings are found internally rather than externally. On the surface, all grooved couplings appear similar regardless of their classification. Rigid and flexible joints differ in their design and tolerance for movement between the connected pipe sections.

In a rigid coupling, the gasket is squeezed tightly within the groove leaving no room for separation, rotation or angular deviation between pipes. This provides a static connection with zero flexibility. However, flexible couplings integrate a design that permits slight separation, rotation or angular misalignment without harming the integrity of the seal or damaging the pipe material. Space is left between the compressed gasket and groove edges to accommodate minor dynamic movement that occurs as a system operates under varied pressures and temperatures over time.
