Purpose of the development: Purpose - pipe insulation extruded polyolefins factory.

Recommended application field: Applications - pipes with the insulation used for the underground laying of gas, oil and water networks with temperature of medium -40 ° C to + 70 ° C.

Technical characteristic: Technical specifications: - Coating thickness - 2.5-3.5 mm; - Adhesion - not less than 35.0 N / cm; - Impact strength - not less than 17.5 J; - The lack of electric breakdown - not less than 17.5 kV; - Transient electric resistance - not less than 1000000000 Ohm x m2; - The area of the cathode peeling - no less than 5.0 cm2.

Advantages over analogues: Benefits: - The installation is used for heating the heating tube current of commercial frequency, providing a more uniform temperature field (the circumferential and pipe length) in comparison with foreign counterparts. Efficiency of the plant up to 93% depending on the working gap.

The development stage readiness: Introduced in production

Description of the development:
()
Description of production technology developed by NPP "Ukrtruboizol." The production process consists of several technological operations, chief among them - cleaning, heating, coating and cooling. Cleaning the pipe installation is carried out shot blasting. After shotblasting pipe surface cleaned to the extent of 1 to GOST 9.402-80, has a matte color and the necessary roughness of 60-90 microns. Heat is produced in the wind or induction furnaces. (KNOW-HOW enterprise). When coating applied technology combined layering adhesive and the polyethylene at the side extrusion through a slit die co-extrusion, thereby eliminating the problems associated with stitching the adhesive layer and to exclude the possibility airing interlayer space. This method of extrusion has reduced the cost of production and operation, while ensuring high quality. Cool coatings - water-air, in which more effectively cools the outer surface of the coating. Performance - 80 km of insulated pipes month. Available from experts NPP experience and knowledge of modern technologies allow them to solve various problems of oil and gas industry related to the pipe insulation. It can be performed any work for the customer.
