Company Profile:
We, YOUNGNAM Metal Co., Ltd., are the leading manufacturer of pipe joint products such as multiplex type couplings, Grip ring type couplings, Repair Clamps and other pipe connectors in South Korea.

Our technical capacity in this field has been highly appraised from many of the client and concerned parties not only the comprehensive application but also a lot of saving of the expenses. The coupling joints, because of the their great flexibility and economy, are steadily replacing the flanged pipe joints nowadays from various industrial plant to the vessel. These coupling joints are not only to eliminate the welding cost but also prevent any linear expansion and deflection of the pipings by welding repairs.

So, in order to achieve the best reputation in this field of the piping connections we will render our best services to our clients and will continue our efforts to research and improve our products.


What we offer:
-The YOUNGNAM GRIP couplings join plain end pipes with axial restraint. YOUNGNAM GRIP coupling provide pull out resistance in excess of the couplings rated working pressure. Whether for pressure or suction lines, thick or thin wall pipe, the YOUNGNAM GRIP couplings are installed quickly, safely and economically. Due to the unique design of the teeth, as internal pressure increases, the anchoring effect is progressively increased. The engagement of the teeth into the pipe's outside surfaces provides for electrical conductivity across the pipe joint.

-The YOUNGNAM REPAIR HINGE is a split in half coupling and open split version of Multi Flex,
offering all the YOUNGNAM REPAIR HINGE benefits, plus being able to make repairs to in service pipe lines. With the YOUNGNAM REPAIR HINGE coupling, leaks due to faulty weld joints, pitting holes and short cracks can be temporarily or permanently repaired with minimal down time. The split gasket design can be wrapped around the pipe and installed without pipe
disassembly. When used to join pipe ends the YOUNGNAM REPAIR HINGE coupling provides the same flexibility features as the Multi Flex design. YOUNGNAM REPAIR HINGE couplings require the pipes to be axially restrained.

-The YOUNGNAM Multi Flex coupling will join virtually any plain end pipe.
Whether pressure or suction lines, thick or thin wall pipe, the YOUNGNAM Multi Flex coupling is installed quickly, safely and economically.
YOUNGNAM Multi Flex coupling can accommodate pipe system expansion and contraction movement as well as angular deflection.
YOUNGNAM Multi Flex coupling require the pipes to be axially restrained and are an economical alternative to rubber and metal expansion joints.
