PEM Korea Co., Ltd. is endeavoring in the manufacture and development of environment-friendly products to preserve nature and the environment.Since 2007, as part of environment-friendly and energy-saving project, we have promoted the research and development of Electric Fusion Welding System which is used for pre-insulated pipes system with P&C Korea Co., Ltd.. From then, we have brought outstanding technical progress and quality innovation in this field. At the same time, we have made an agreement on cooperation for the development of overseas market and the research of energy-saving project with DAEKYUNG ENERTECH Co.,Ltd., which is one of the leading manufacturers of pre-insulated pipe in Korea.
PEM Korea Co., Ltd. has taken over the plastic pro-cessing department of Daelim Industry Co., Ltd., whose excellence in construction, engineering and environmental works has been recognized since its entry into the field of plastic processing in 1987. PEM Korea Co., Ltd. will be reborn as a specialized com-pany that supplies environment-friendly products by further developing the synthetic plastic processing industry which has been playing a crucial role in the national progress in the field of construction, engi-neering and environmental works.

Acquired the patent‘Electric Fusion Welding System for Pre-insulated pipe’[Patent No.10-0829532]Concluded the joint research & development contract of Electric Fusion Welding system with P&C Korea
The pre-insulated pipe system has been developed continuously and used widely on all sides of the industry while substituting for traditional insulation methods.
The pre-insulated pipes which are composed of the carrier pipe, polyurethane foam and HDPE jacket as a main elements, are manufactured under factory-controlled conditions, so that this system may ensure high standard quality level.
Combining each expertise and experience, PEM Korea has cooperated closely with DAEKYUNG EN-ERTECH Co.,Ltd. and P&C KOREA Co.,Ltd. to meet the customer's needs and requirements.
PEM Korea pre-insulated pipe system can be characterized as follows, Various carrier pipes and polyurethane foam insulation are used to transport of liquids and gases with temperatures ranging from -200°C to 250°C.HDPE Jacket pipe makes secure a waterproof, durability and UV-resistance of pre-insulated pipe. Computer-controlled electric fusion welding joints ensure a completely watertight pipe system.
The above stated advantages will provide customers with versatile solutionsand enlarge opportunities to obtain more safety and quality as well as economic benefit.

DURABILITY
PEM Korea pre-insulated pipes are insulated with polyurethane foam which hasextremely low heat conductivity, the best insulation commercially available on the market.Exceptionally effective insulation that complies with most stringent international standards, provides with excellent thermal insulation for customer.
The pre-insulated pipe systems provide excellent durability as well as complete thermal integrity throughout their minimum 50 years of service life. As combining with PEM Eletric Fusion Welding Joints, this system is completely connected and behave as one unit.Every single component is designed and tested to ensure corresponding durability in accordance with EN253, EN448, EN488, EN489 with high quality from factory to site.
WATERTIGHT AND CHEMICAL RESISTANCE
PEM Korea pre-insulated pipe system protects carrier pipe against external corrosion, that is to say, it provides100% waterproof insulation.For the property of HDPE jacket has exceptional resistance to any intrusion of salt, chemistry and ultra-violet, there is no need for painting, coating or any other anti-corrosion of the service pipe.
