UnisonHKR Construction Business Unit

UnisonHKR Co., Ltd. has developed core technology and the best quality in plant and construction business becoming the unquestionable leader of the industry.

General Informartion

The plant division covers piping support, expansion joint and damper businesses based on the technology accumulated as the industry-leading company, supplies its products to many domestic power plants as well as piping lines of top-class plants overseas.

Construction Business Unit is responsible for construction, technology development and production of seismic isolation, seismic bearings and vibration control devices which support bridges or buildings and increase safety against earthquakes and wind loads. It also produces other construction materials such as bridge expansion joints, soundproof walls, composite sheet piles, and has established business divisions for materials supply, monorail construction and special business.

Pipe Support

Pipe support is a device installed to support and protect the Piping system from the weight of pipes, mutations due to heat expansion, fluid vibrations, earthquakes and other exterior impacts, thereby maintaining the safety of the Piping system. In the plant facilities, the pipe line is the same as blood vessel of the human body. The purpose of Pipe support is smooth delivery of WATER, STEAM, GAS and other liquids in each of the piping system.

A program that allows customers to design 2D in the design stage to apply the UET products. Products (Variable Spring Hanger, Constant Spring Hanger, Strut, Snubber) Check external dimensions, installation height and surrounding interference Check estimated BOM, Check installation drawing.

Variable spring hanger

spring hangers are used to carry the dead weight of the piping system at a given support while allowing movement resulting from thermal expansion or contraction of the piping system. It is used in places where heat displacement is low, has simple structure and low price.

Constant spring hanger

Piping Technology & Products’ constant support hangers are principally used to support pipes and equipment subjected to vertical movement due to thermal expansion at locations where transfer of stress to other supports or equipment can be critical. It is used in main lines where there should be near-zero change of stress magnitude on pipes or equipment.

Cold Support

Made for LNG, LPG and other petrochemical constructions, Cold Support is a pipe-supporting device which can be used in temperatures as low as minus 190 degrees centigrade. Often made from polyurethane and compression molding wood, Cold Support safely supports the pipes by cutting off heat conduction in low or even extreme-low temperatures and maintaining ample intensity.

Sway Strut

A sway strut is a device used to restrain movement of piping in one direction while providing for movement due to thermal expansion or contraction in another direction.

Hydraulic Snubber

Hydraulic Snubbers are used to control movement during abnormal conditions such as earthquakes, turbine trips, safety/relief valve closure. Snubbers allow for free thermal movement of a component during regular conditions, but restrain the component in irregular conditions.

Expansion Joint

Expansion Joint is a product that maintains the piping system and protects equipment by absorbing high stress magnitude on pipes due to outer temperatures that may influence energy delivering pipes, pipe expansion or contraction caused by temperature changes in fluids, equipment vibration problems, wind pressure or earthquake.
