Since the establishment of Unison Hi-Tech Co., Ltd. in 1984, we became a leading manufacturer of pipe hangers andsupports equipment. We built our success in the Nuclear power plant & other conventional power plant industry bysupplying high quality products that meets the international safety standards.

As a leader in manufacturing pipe hangers and supports equipment, we aim to maintain customer satisfaction through

continuous investment in product development and improvement. Unison Hi-Tech Co., Ltd. has been awarded for

Excellent Enterprise for Quality Competitiveness for 10 consecutive years and evolved into a leader in the pipingproduct manufacturing business.

In 1997, Unison Hi-Tech Co., Ltd. acquired the ASME NA, NPT, NS & KEPIC certificate for pipe hangers and supportsequipment, which demonstrates that our products are proven for quality. We were the first Korean corporation to obtainISO9001 Quality Management Certificate in the field of pipe support equipment for all our piping products and also

obtained ISO 14001 Environment Management Certificate in 2006.

Unison Hi-Tech Co., Ltd. has carried out several programs designated by the Korean government and gained recognitionas one the nation's most respected "quality" piping equipment manufacturer.

We plan to maintain our role as a leading company in the pipe support equipment field by committing ourselves tosurpass customer expectation through continuous research and development of our full product line.

1. Constant spring hanger

2. Variable spring hanger

3. Sway strut

4. Sway brace

Sway strut constrains the displacement of pipe in one direction while letting it

move freely in another direction. Since spherical bearing is attached, this product

can correspond to slight angular motion.

Sway brace suppress the vibration of pipe, absorbs impact loading, guides or

constrains the motion of pipe, and holds the pipe in place.

8. Installation & m aintenance

Pipe Supports are classified in several models and types, so we

provide installation service for customer. Regardless of location, we will

generally provide technical s ervice as stated below, upon request.

1. Training & education

2. Technical assistance & consultant

3. Installation guidance

5. Hydraulic snubber

6. Mechanic al snubber

Mechanical Snubber is composed of ball screw axis, ball screw, fly wheel and disk

brake. When t he heat displacement of p ipe moves slowly in a normal condition, the

ball screw of the mechanical snubber rotates slowly so that the pipe can move

freely. But when the pip e receives sudden impact such as earthquake & etc., the disk

brakes is activated and the ball screw axis will stop rotating because the fly wheel can

not execute a sudd en rotary motion. The mechanical snubber will deliver the imapactload to the steel structure to protect the pipe.

7. Cold support

Cold support is used in LNG, LPG and other petrochemical constructions and can

be used in the low temperature area as low as 190c below zero. The material of cold

support is mainly polyurethane, compressed & shaped wood to cut off heat

conduction in extremely low temperature, so it protects the pipe by maintaining its

intensity.

ProductsSince its establishment in 1984, as a leading manufacturer for pipe hangers & supports equipment in Korea, we have

supplied high quality products to the Nuclear power plant & other conventional power plant industry.

The Constant Spring Hanger has a spring coil compressed in its cylindrical design.

It shares the same concept as the Variable Spring Hangers. When the pipe issubjected to vertical movement the Constant Spring Hanger controls internal stressagainst force being applied to the pipe and so it provides constant supportcontrolled by a specially devised mechanism. Constant Spring Hanger is installed inthe main pipeline, where transfer of stress to other supports or equipment can becritical.

Variable Spring Hanger has precompressed spring coil in its cylindrical design.When pipe vertical movement occurs due to thermal expansion, the repulsive force

of the spring coils will change accordingly. They are typically installed in pipinglocations with low heat displacement. The strong points of this spring hanger type isits simple design and low price.

Hydraulic Snubber is composed of a cylinder, oil tank and check valve. When the

heat displacement rate of the pipe is relatively low in normal conditions, the HydraulicSnubber allows free thermal movement of the pipe with little resistance. But whensudden impact is applied to the pipes from fluid vortex, wind load or earthquakes, thecheck valve will close and pistons will stop allowing the Hydraulic Snubber to deliverthe impact load to the steel structure to protect the pipe.
