Rigid polyurethane foam has been used for the insulation and protection of pipes for more than 30 years. It is now more widely used than ever, increasingly displacing alternative materials. One of the most popular areas of use is for district cooling systems, where it is the insulant of first choice for many specifiers. Other common uses are in: Insulation Steel Pipe with PUR Foam and HDPE Jacket - Hdpe We take a holistic approach to each project and provide engineered solutions with all the technical, training, and installation support Insulation Steel Pipe with PUR Foam and HDPE JacketEPPI Preinsulated carbon steel pipesThe preinsulated pipe system is made up of steel carrier pipe, 100% CFC free polyurethane insulation foam and seamless solid wall HDPE jacket.

Latest methods in preinsulated underground chilled water

Dec 31, 1996 · In the first part of this paper, some of the newest design features of hot water district heating piping are described. Emphasis is on polyurethane preinsulated one- and two-pipe elements equipped with a polyethylene jacket pipe. The paper also deals with the newest developments in concrete culvert district heating lines, namely the Petromar Piping Systems LLCInsulation At Petromar we use Polyurethane (PU)/ Polyisocyanurate (PIR) as the insulation material. We follow EN 253 standard for insulation where is we use high pressure foam which is injected into the annular space between the core and the jacket pipe. PU is a polymer composed of a chain of organic units joined by carbamate (urethane) links. Pre-Insulated Piping System - NAFFCO Flow ControlHigh Pressure Injected Foam - It is directly injected to fill the annular space between the core & Jacket. Polyurethane insulation foam fills the space between the service pipe and the outer protective jacket have the following characteristics:Coefficient of thermal conductivity less than 0.033 W/mk.

Pre-insulated Pipes - Specialized Engineering Contracting Co.

The pre-insulated piping system consisting of carbon steel as the core pipe and high density polyethylene (HDPE) as the jacket pipe has been the most successful system used in pre-insulated piping networks throughout the history of the industry.This sytem is used for the underground transport of hot and cold fluids at working temperatures in the range -32° C to +142° C, it is a very durable and Pre-insulated pipe - All industrial manufacturersCOOLMANT. Inner diameter:125 mm - 315 mm. Outer diameter:225 mm - 450 mm. Pressure:0 bar - 16 bar. The COOLMANT is an insulated pipe system that is used for applications that require cold water, waste water and district cooling. It consists of an inner pipe which is made from polyethylene Preinsulated pipes of INSTALL ENGINEERINGPREINSULATED PIPES. INSTALL ENGINEERINGs high quality pre-insulated pipes are based on eco-friendly production process, complying with the international standards for this type of production. The insulation layer is consisted of ecologically clean polyurethane foam and isocyanate foam without Freon. This type of insulation has the lowest thermal conductivity:=0.018-0.029 W/m.K, which
