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.

UL FM Grooved Rigid Couplings

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.

UL FM Grooved Split Flange

Grooved Split Flange is a key component for achieving system modularization, rapid installation and maintenance in modern pipeline installation. It perfectly combines the installation efficiency of the grooved system with the universality of the flange interface.

UL FM Grooved Mechanical Tee

Grooved Mechanical Tee is a special pipe fitting used for opening branches in existing pipes. Its core feature is that branch connections can be completed without cutting the main pipe.

UL FM Threaded Mechanical Tee

Threaded Mechanical Tee has the same function as grooved mechanical tee. Both are mechanical pipe fittings used to make holes and branches on existing pipes.

UL FM U-Bolt Mechanical Tee

U-Bolt Mechanical Tee is a special pipe fitting used for quickly opening branches on existing main pipelines. It achieves mechanical fastening through U-bolts without cutting the main pipeline and is highly suitable for small-diameter connections in narrow Spaces.

UL FM Grooved End 90 Degree Elbow

Grooved 90° Elbow (grooved 90-degree elbow) is a standard pipe fitting with grooves at both ends, used to change the direction of the pipe to a right Angle.

UL FM Grooved 45° Elbow

Grooved 45° Elbow (grooved 45° elbow) is a standard connector used to change the direction of pipes by 45 degrees.

UL FM Grooved 22.5° Elbow

The 22.5° elbow is mainly used for precise and minor directional fine-tuning, or to replace multiple elbow combinations in complex pipe network layouts to achieve specific angles.

UL FM Grooved 11.25° Elow

The 11.25° grooved elbow is not a common component for daily use, but a specialized part for achieving the highest hydraulic efficiency, the lowest noise and precise spatial adaptation in pipeline systems.

UL FM Grooved Equal Cross

Grooved Equal Cross is a fundamental component for achieving standard four-way connections in piping systems.If the branch pipe diameters are different, Grooved Reducing Cross should be selected.

UL FM Grooved Reducing Cross

Grooved Reducing Cross is an efficient solution to the problem of "multi-directional intersections" in pipeline systems. Its value lies in transforming complex customized connections into a reliable, standard and easy-to-install prefabricated component.
