BST Polyethylene Pipes

[INQ. NO. 2208M06] Bosung Polytech’s BST pipes are economical and have long durability. This is because of the characteristics of polyethylene, the main material of the BST pipe.

As polyethylene is cheap and lightweight, it can shorten the construction period. In addition, the polyethylene pipe is not easily contaminated with acid, alkali, salt or bacteria, and does not break easily when applied.

BST pipe has improved the strength of polyethylene pipes with its proven production technology and is used in various industrial fields such as water pipes, sewer pipes, and floating structures due to its excellent economical and durable features.

Polyethylene pipe for water supply
This is used for agriculture, seawater for industry use, dredging, leachate, chemicals, aquafarm, pool, plant, sprinklers in golf courses, and firefighting equipment. BST is a public procurement enterprise and has been supplying quality products to public institutions since 2005.

Water-supply pipes were also provided to coal-fired power plants in Dangjin, Hadong, and Samchonpo, and about 50% of sales are made through public procurement. Specifications of the diameters are from 16mm to 710mm, and for length they are 6m or 10m based on ISO standards.

Structural polyethylene sewer pipe
These are used for sewer treatment, agriculture, wastewater, rainwater, water supply, livestock waste treatment facility, and pipes for land readjustment and development. Specifications of the diameters are from 16mm to 710mm, and for length they are 6m or 10m, but customizing is also possible.

Double-wall pipe
This product is made of a double-wall structure by extruding a high-density polyethylene (HDPE) mechanically.

The I-beam between the inner and outer tubes forms a central layer at regular intervals. Compressive strength is high, it is resistant to corrosion, and can be used semi-permanently.

Multi-wall pipe
This is made of a double-wall structure by extruding high-density polyethylene (HDPE) mechanically. The multi-wall structure reinforcing the inner profile with the “+” type I-beam between the inner and outer tubes forms a central layer at regular intervals, and is strong against external pressure and impact.

Off shore floating structure
This is used for gangways and piers for docking facilities of off shore amenities, floating-type pools, recreational structures, off shore fishing parks, live experiences at a fishing village, mud-flats, etc. | Blog Magazine of korean-machinery, brands and Goods

Couplings, Clamps[INQ. NO. 1801M08] Founded in 1995, Jung Woo Coupling, a small company, manufactures couplings and clamps to connect pipes. However, the company has been recognized as a small but strong company in exporting to 35 countries including Japan, the USA, the UK, France, Norway and Australia.
Couplings connect two pipes and are mainly used for the installation of pipes. Clamps are used to fix or overlay pipes on other pipes for maintenance purposes. Couplings and clamps are recognized as products that can replace existing cumbersome and difficult piping connections such as welding. If a user only locks bolts on couplings and clamps, the user can easily connect pipes, thereby saving the user work time and cost.
Couplings and clamps can be used in a variety of industries including shipbuilding, power generation, chemical, petroleum, housing, and construction. Couplings and clamps are already widely used in Europe such as the UK and Germany, but not in Korea.
For this reason, Jung Woo Coupling is known as the best manufacturer in the field of couplings and clamps in Korea. “With only one or two companies producing pipe couplings and clamps in Korea, our company feels a sense of responsibility as a leading company in Korea,” remarked Yoo In-tae, CEO of Jung Woo Coupling. “In particular, we are proud of the fact that we are recognized around the world as we have invested in research and development over the past 16 years.”

Jung Woo Coupling has concentrated its research efforts on improving quality and technology since its establishment. The company registered four utility models by applying their own technology to foreign products. As an example, Jung Woo Coupling improved the compression of saw teeth of pipes’ connection parts of couplings to prevent leaks and improve connection strength.
In addition, the company made products that can be used only for straight pipes available for “ㄱ-shaped” pipes, and enhanced product performance so that pipes made of different materials can be connected. That is to say, they made installation work easier by developing assembly-type couplings that connect large sewer pipes that pass through cities and small sewer pipes for homes.
Compared to this technology, Jung Woo Coupling products are about 30% cheaper than those of overseas major manufacturers. Jung Woo Coupling secured cost competitiveness through quality management by reducing cost through quality certification and reducing expenses incurred in the production process. | Blog Magazine of korean-machinery, brands and Goods

No-power Water Treatment System[INQ. NO. 1709M02] IOREX produces live water as the world’s best no-power water treatment system, which has been developed by IOREX Co., Ltd. IOREX effectively removes and prevents rust and scale by instant ionizing water that passes through a water-supply system. This is the most natural and environmentally friendly water treatment system that also helps living things grow and keeps them healthy by activating water.
When water passes the IOREX, static electricity arises due to friction on the contact surface.
And when the electrical charge rises by absorbing the static electricity it emits the outer nuclear electrons and becomes charged. Then, a strong static electricity field is created via the transfer of the electrical charge and when water passes through the static electricity field it gets instantly ionized.
The company’s CEO explained, “We have developed a device for water treatment, and now we are launching IOREX as a result of many years of research and development. It is a device of “Water treatment with No power, No medicines as Green”; IOREX is a product that offers a well-being lifestyle to humankind and provides solutions for the rust and scales problems in pipes, and also it provides a healthy life and helps nurture the growth of plants and animals.” | Blog Magazine of korean-machinery, brands and Goods

Pipe couplings & clamps

Products selected by Gyeongsangnam-do

[INQ. NO. 1505M20] Established in 1995, Jeongwoo Coupling has been producing pipe couplings for pipe connection, and pipe repair clamps for pipe repair. The pipe couplings permit easy, safety operations. They enable repeated operations of installation and disassembly, with assurance of savings in cost and time. So, it is called a product that can substitute the welding or the fl ange construction. pipe couplings show big advantages over competitors manufactured by domestic and foreign makers. They absorb bending and sag (deflection), impact, vibration, and noise. And while slip type of pipe couplings show big performance in absorbing expansion, grip type prevents detubulation. They connect pipes of different material. No treatment of pipe ends is required. It is recommended, in actual use, which just uses a wrench to install. They are secure against fi re due to non- use of fl ammable material, and can save work space because installation is done only on one side.

Pipe-couplings-&-clampsBased on technology innovation, currently around 70 percent of its pipe couplings are exported to more than 40 nations including Japan, England, France, the USA, Singapore, Norway, Sweden, Australia, etc. Domestically, they are also delivered to large sizes of companies such as Samsung, Hyundai, Doosan, LG, SK, with stable supply to small and medium-sized enterprises. | Blog Magazine of korean-machinery, brands and Goods
