Dury Chemical Co., Ltd. has been growing and developing as a plastic pipe material producer since its founding as Daesung Chemical, the parent plant, in 1974.

The company which has been putt ing enormous eff orts into meeting customers’ needs and achieve customer satisfaction, fi nally developed the method that can dramatically reduce drainage noise and dew condensation, the largest drawback of apartment housing plumbing system, and has been recognized for its outstanding performance, by the leading construction companies to which it supplied.

Equipped with the country’s largest production facilities and automated manufacturing processes, and by operating the best-quality management system, it is focusing on preventing nonconforming products and follow-up management. Also, Dury Chemical Co., Ltd. pledges to be reborn as an enterprise that always researches and develops with the customers, based on its management philosophy of “Customer Satisfaction Management,” in the 21st century.

NC and EDR Systems ? Representative Products of Dury Chemical Co., Ltd.
NC pipe is threefold pipe composed of a PVC outer layer, a special sound insulation layer, and a PVC inner layer. It possesses excellent sound insulation capacity due to the special sound insulation layer. Compared with existing PVC tubes, it has excellent impact resistance. Since it is a structure for special sound insulation, it has excellent insulation capacity compared with existing tubes (general tubes). Sound insulation material is included in a special sound insulation layer that it can eff ectively block inside tube noise. It is used for plumbing for drainage and ventilation and for indoor vertical plumbing.

EDR system is non-toxic and there is no concern for water pollution due to the application of special mineral materials of high-quality polyvinyl chloride polymer. The connecting parts are made of unique joint structure; special ringbonding structure which secures the pipe and rubber-ring shaped special form structure. These structures give superior coherence to the pipe compared with other parts, so there is no risk of leakage. Furthermore, it has excellent mechanical strength, weatherability and durability. Compared with cast-iron pipes, handling and installation is easy.

EDR’s impact strength is far superior to the cast-iron pipe because of the impact resistance materials used. Away from the existing connection method, the pipe and fi tt ings are connected by a one-touch method, and the construction is much faster.

Especially, the connection accessory ? seamed pipe ? boasts of simple cap-tightening method compared with the existing products. Excellent clamping force ensures no risk of leakage and excellent constructability due to simple connection method of pipe and seamed pipe.

DMT Co., Ltd. provides a total solution from custom design, to manufacturing, construction for expansion joints, which is used to prevent fatigue failure from thermal expansion, contraction and vibration, to realize customer satisfaction.

DMT Co., Ltd. is fully equipped with facilities to manufacture various expansion joints (metal, rubber, Tefl on, fabric) up to large size. Especially, Tefl on expansion joint, which is chemically resistant, was certifi ed with NET in 2014 and NEP in 2014. Now, it is being supplied to power plants and petrochemical companies in Korea.

Tefl on Expansion Joint P-Type & H-Type

Dmtfl ex’s hot-fl ex expansion joint system is an engineered product that was specifi cally designed to provide high pressure / temperature transfer containment of highly corrosive mediums that could not be safely handled by conventional metallic, elastomeric or Tefl on expansion joints. Dmtfl ex’s hot-fl ex combines the high pressure rating of a metallic expansion joint with the high temperature corrosion resistance of Tefl on, creating a product that will outperform them both.

Each Hot-fl ex expansion joint can be custom engineered to clients’ specifi c applications: pressure / temperature rating, spring rate movement (axial, lateral and angular) metallic carcass (stainless steel, Inconel, hasteloy, etc.) of various lengths.

Dmtfl ex’s Tefl on expansion joints are used primarily in fl uid conducting systems as resilient connectors and tremor barriers. They are designed to compensate for misalignment, to absorb expansion and contraction and to isolate vibrational shock. They are also frequently used to reduce stress on fragile mating fl anges.

Fine Motors Co., Ltd. was established in 2002 by gathering manpower who had worked in the related fi elds of specially equipped vehicles. Based on solid technologies, it has thus been able to develop 124 types of certifi ed vehicles including a compost-scatt ering vehicle and customized vehicles with functionality and effi ciency for each diff erent purpose. Its main vehicles include those for fueling, water supply, a special tank lorry, an arm roll truck and cleaning vehicles such as a honey wagon and a refuse cart. Besides these, it has developed and manufactured construction vehicles such as general and special dump trucks and special vehicles including a water cannon vehicle, a fumigator truck and a catt le truck.

Fine Motors Co., Ltd. has been able to earn the ISO 9001, an INNOBIZ company certifi cate, Export top company award, as well as an employment top company certifi cate and fi refi ghting administrative development award from the Minister of Safety and Administration. By completing its registration with UNGM and SAM, the company is now preparing a stage to supply vehicles to the international agency and the U.S. Federal government and extending its export market.nd Fueling Vehicle

A water cannon vehicle enables installation of nozzles on left and right sides of the vehicle that can shoot and reach a minimum range of 60 meters, and a mixture of water with teargas, dye or fi refi ghting foam. Bulletproof processing is possible for windows as well as engine to protect the passengers and vehicle, and bulldozer installation is also possible to disperse demonstrators and to protect the vehicle from street wastes. All specifi cations can be customized to meet clients’ needs.

There are various kinds of fi refi ghting vehicles, including rescue vehicle with equipment for on-site activities, pump vehicle for fi refi ghting, ladder vehicle to help fi refi ghters to access tall buildings, and a water tank vehicle that supplies water to pump or ladder vehicles. Also, it manufactures integrated command vehicles that can control all the vehicles and situations and other fi refi ghting equipment vehicles for various disastrous situations. Again, all specifi cations can be customized for clients’ needs.

Fueling vehicles can carry fuel and refueling for other vehicles. They are widely used for military, police and airports. It is possible to adjust tank-capacity for various purposes and other specifi cations as well.
