Product Introduction

The sealing rubber ring is wound around the ends of the two connected pipes during assembly to form an initial seal.

The two-piece clamp is sleeved on the outside of the sealing ring, and the protruding part of its inner edge will precisely fit into the annular groove at the end of the pipe.

The bolts and nuts are tightened by evenly tightening the bolts to pull the two clamps together. This action will simultaneously compress the sealing ring to enhance the seal and mechanically interlock the raised part of the clamp with the pipe groove, thereby completely preventing the pipe from being pulled apart or rotated.

The grooved rigid coupling is a specialized component for mechanical connection of pipes. It forms a rigid, weld-like stable connection between the ends of pipes that have been pre-machined with annular grooves through clamps, gaskets and bolts. It is widely used in systems such as fire protection and industry where high stability of pipelines is required.

Product Features

• After connection, relative movement is not allowed to form a rigid coupling system.

• Compared with traditional welding or flange connection, its installation is faster and safer (no hot work is required), and it is also convenient for later system maintenance and renovation.

• The "heel" structure on the inner edge of the clamp will be deeply inserted into the pipe groove to achieve mechanical locking.

UL FM Malleable Iron Pipe Fittings

Malleable iron pipe fittings are components used to connect, terminate, control, and change the direction of pipes in a pressurized gas or liquid piping system. They are designed for use with threaded pipe, most commonly black iron pipe or galvanized iron pipe.
UL FM Grooved Coupling

Grooved pipe fittings are mechanical pipe connection components used to quickly connect two sections of pipes by pressing gaskets and rings onto the grooves machined on the outside of the pipes.
UL FM Grooved Fittings

Grooved pipe fittings are a general term, referring to all pipe assemblies that use grooved mechanical connection systems. This system achieves rapid and reliable connection between pipes and pipe fittings, valves or equipment by pressing grooves at the pipe ends and combining them with dedicated couplings and gaskets.
Mechanical Tee and Cross

Mechanical Tee and Mechanical Cross both belong to grooved Outlet Fittings. They do not need to be welded or drilled on the main pipeline, but instead branch out one or two vertical branches directly from the existing main pipeline through mechanical means (such as U-bolts and gaskets).
UL FM Grooved Flange

Grooved flanges are a type of hybrid pipe fitting, with one end being a standard flange surface and the other end being a groove.

The grooved rigid pipe coupling is an efficient and reliable solution for connecting large-diameter pipes in modern fire protection engineering. Its core value lies in providing stable and firm structural support.
UL FM Grooved Flexible Couplings

Grooved flexible coupling are mechanical pipe joints that allow limited movement of pipes at the connection points. They are specifically designed to absorb vibration, thermal expansion and contraction, and building displacement, complementing the functions of rigid coupling.
UL FM Grooved Flexible Reducing Coupling

The reducing coupling offers a fast, reliable connection solution that does not require welding or flange reduction, greatly simplifying the design and installation of pipeline systems.
